What is the capacity of the battery?
The capacity of the battery refers to the amount of electricity that the active material in the battery can participate in the electrochemical reaction is called the capacity of the battery, that is, the amount of charge that the battery can hold after charging. The unit is “Ah” (Ah) and 1 A (A). The current is discharged for 1 hour, and the capacity is 1 ampere hour (Ah). Assuming that the average current is 4A, the discharge time is 3 hours when the battery is discharged at the termination voltage of the battery, and the battery capacity is 12Ah (the discharge is not calculated here) effectiveness).
What is battery internal resistance?
It refers to the resistance to the current flowing through the battery when the battery is working. There are two parts: ohmic internal resistance and polarization internal resistance. Large internal resistance of the battery will cause the battery’s discharge working voltage to decrease and shorten the discharge time. The internal resistance is mainly affected by the battery material, manufacturing process, battery structure and other factors. Is an important parameter to measure battery performance.
Can I fast charge my battery?
La charge rapide n'est pas recommandée car elle est nocive pour la batterie.
What are the reasons for the battery warming up during charging?
Pendant le processus de charge de la batterie, une partie de l'énergie électrique est convertie en énergie chimique et une partie de l'énergie électrique est convertie en énergie thermique et autre énergie. Il est normal que la batterie rechargeable chauffe, mais lorsque la température est trop élevée, vous devez vérifier si le courant de charge est trop important ou si un court-circuit se produit à l'intérieur de la batterie.
What is the battery's charge acceptance?
Dans les conditions de tension et de courant de charge spécifiées, la quantité de charge que la batterie accepte par unité de temps.
What is the harm of the battery heating?
La batterie est autorisée à avoir une petite quantité de chaleur, que ce soit en cours d'utilisation ou pendant la charge, mais une chaleur anormale n'est pas autorisée. La fièvre anormale est évidente et vous pouvez la sentir en touchant le boîtier de la batterie avec votre main. La chaleur est très nocive pour la batterie. La chaleur provoque d'abord l'évaporation et l'assèchement progressif de l'eau de l'électrolyte, puis diminue l'efficacité de la charge, la déformation des plaques, l'augmentation de la résistance interne, l'oxydation accélérée des pièces mécaniques, les plaques ou les séparateurs brûlés, et se manifeste enfin par une capacité réduite de la batterie et durée de vie raccourcie.
What is the danger if the connecting bolts are not tightened?
Une connexion desserrée entraînera une augmentation de la résistance au niveau de la connexion, ce qui provoquera facilement des étincelles lors de la charge et de la décharge. Dans les cas graves, cela provoquera de la chaleur et un incendie, et un accident se produira.
How to maintain the consistency of the battery pack?
Although the lead-acid battery has been strictly selected when it leaves the factory, after a certain period of use, the non-uniformity will appear and gradually increase. The charger can’t recognize or supplement the undercharge. How to balance the battery capacity? It must be performed by humans. The user measures the open circuit voltage of each battery periodically and irregularly during the middle and late periods of battery pack use. For lower voltages, recharge separately to make the voltage and capacity consistent with other batteries, and try to reduce their gap.
Can I do a partial replacement of my batteries?
Le remplacement partiel de la batterie des groupes de batteries au plomb-acide n'est pas recommandé.
Are you a battery manufacturer, and do you produce the plates by yourself ?
Oui, nous sommes un fabricant professionnel de batteries dans la province de Guandong, en Chine depuis 2003. Nous produisons des plaques de plomb par notre propre atelier.
Does your battery develop a memory?
Les batteries au plomb ne développent aucun type de mémoire. Cela signifie que vous n'avez pas besoin de décharger profondément ou de décharger complètement une batterie avant de la recharger. Pour une durée de vie et des performances optimales, nous recommandons généralement une décharge de 20 à 50% de la capacité nominale de la batterie, même si la batterie peut être cyclée à 90%.
How does temperature affect the performance of my batteries?
À des températures plus élevées (supérieures à 77 °F (25 °C)), la capacité de la batterie augmente généralement, généralement au détriment de la durée de vie de la batterie. Des températures plus élevées augmentent également la caractéristique d'autodécharge. Des températures plus froides (inférieures à 77º F (25º C)) réduiront la capacité de la batterie et prolongeront sa durée de vie. Des températures plus froides ralentiront l'auto-décharge. Par conséquent, faire fonctionner les batteries à des températures égales ou légèrement inférieures à 25 °C (77 °F) optimisera à la fois les performances et la durée de vie.
How to charge a battery to be at 100% state of charge healthiest?
You may have heard it said “you need a 3 stage charger”. We’ve said it, and we’ll say it again. The best kind of charger to use on your battery is a 3 stage charger. They are also called “smart chargers” or “micro processor controlled chargers”. Basically, these types of chargers are safe, easy to use, and will not overcharge your battery. Almost all of the chargers we sell are 3 stage chargers. Okay, so it’s hard to deny that 3 stage chargers work and they work well. But here’s the million dollar question: What are the 3 stages? What makes these chargers so different and efficient? Is it really worth it? Lets find out by going through each stage, one by one:Stage 1 | Bulk ChargeThe primary purpose of a battery charger is to recharge a battery. This first stage is typically where the highest voltage and amperage the charger is rated for will actually be used. The level of charge that can be applied without overheating the battery is known as the battery’s natural absorption rate. For a typical 12 volt AGM battery, the charging voltage going into a battery will reach 14.6-14.8 volts, while flooded batteries can be even higher. For the gel battery, the voltage should be no more than 14.2-14.3 volts. If the charger is a 10 amp charger, and if the battery resistance allows for it, the charger will put out a full 10 amps. This stage will recharge batteries that are severely drained. There is no risk of overcharging in this stage because the battery hasn’t even reached full yet. Stage 2 | Absorption ChargeSmart chargers will detect voltage and resistance from the battery prior to charging. After reading the battery the charger determines which stage to properly charge at. Once the battery has reached 80%* state of charge, the charger will enter the absorption stage. At this point most chargers will maintain a steady voltage, while the amperage declines. The lower current going into the battery safely brings up the charge on the battery without overheating it.This stage takes more time. For instance, the last remaining 20% of the battery takes much longer when compared to the first 20% during the bulk stage. The current continuously declines until the battery almost reaches full capacity.*Actual state of charge Absorption Stage will enter will vary from charger to chargerStage 3 | Float ChargeSome chargers enter float mode as early as 85% state of charge but others begin closer to 95%. Either way, the float stage brings the battery all the way through and maintains the 100% state of charge. The voltage will taper down and maintain at a steady 13.2-13.4 volts, which is the maximum voltage a 12 volt battery can hold. The current will also decrease to a point where it’s considered a trickle. That’s where the term “trickle charger” comes from. It’s essentially the float stage where there is charge going into the battery at all times, but only at a safe rate to ensure a full state of charge and nothing more. Most smart chargers do not turn off at this point, yet it is completely safe to leave a battery in float mode for months to even years at a time. It’s the healthiest thing for a battery to be at 100% state of charge. We’ve said it before and we’ll say it again. The best kind of charger to use on a battery is a 3 stage smart charger. They are easy to use and worry free. You don’t ever have to worry about leaving the charger on the battery for too long. In fact, it’s best if you DO leave it on. When a battery is not at a fully charged state, sulfate crystal build on the plates and this robs you of power. If you leave your powersports in the shed during off-season or for vacations, please connect the battery to a 3 stage charger. This will ensure that your battery will be ready to start whenever you are.
Does over-discharging damage batteries?
Over-discharging is a problem which originates from insufficient battery capacity causing the batteries to be overworked. Discharges deeper than 50% (in reality well below 12.0 Volts or 1.200 Specific Gravity) significantly shorten the Cycle Life of a battery without increasing the usable depth of cycle. Infrequent or inadequate recharging can also cause over discharging symptoms called SULFATION. Despite that charging equipment is regulating back properly, over discharging symptoms are displayed as loss of battery capacity and lower than normal specific gravity. Sulfate occurs when sulfur from the electrolyte combines with the lead on the plates and forms lead-sulfate. Once this condition becomes occurs, marine battery chargers will not remove the hardened sulfate. Sulfate can usually be removed by a proper desulfation or equalization charge with external manual battery chargers. To accomplish this task, the flooded plate batteries must be charged at 6 to 10 amps. at 2.4 to 2.5 volts per cell until all cells are gassing freely and their specific gravity returns to their full charge concentration. Sealed AGM batteries should be brought to 2.35 volts per cell and then discharged to 1.75 volts per cell and then this process must be repeated until the capacity returns to the battery. Gel batteries may not recover. In most cases, the battery may be returned to complete its service life.CHARGING Alternators and float battery chargers including regulated photo voltaic chargers have automatic controls which taper the charge rate as the batteries come up in charge. It should be noted that a decrease to a few amperes while charging does not mean that the batteries have been fully charged. Battery chargers are of three types. There is the manual type, the trickle type, and the automatic switcher type.
What are primary and secondary batteries?
Les piles primaires sont des piles sèches ordinaires, ne peuvent être utilisées qu'une seule fois. Les batteries secondaires sont également appelées batteries rechargeables, elles peuvent être chargées et déchargées plusieurs fois. Nos batteries sont des batteries secondaires.
What is battery rating?
The most common battery rating is the AMP-HOUR RATING. This is a unit of measurement for battery capacity, obtained by multiplying a current flow in amperes by the time in hours of discharge. (Example: A battery which delivers 5 amperes for 20 hours delivers 5 amperes times 20 hours, or 100 ampere-hours.)Manufacturers use different discharge periods to yield an different Amp-Hr. Rating for the same capacity batteries, therefore, the Amp-Hr. Rating has little significance unless qualified by the number of hours the battery is discharged. For this reason Amp-Hour Ratings are only a general method of evaluating a battery’s capacity for selection purposes. The quality of internal components and technical construction within the battery will generate different desired characteristics without effecting its Amp-Hour Rating. For instance, there are 150 Amp-Hour batteries that will not support an electrical load overnight and if called upon to do so repetitively, will fail early in their life. Conversely, there are 150 Amp-Hour batteries that will operate an electrical load for several days before needing recharging and will do so for years. The following ratings must be examined in order to evaluate and select the proper battery for a specific application: COLD CRANKING AMPERAGE and RESERVE CAPACITY are ratings used by the industry to simplify battery selection.
What does the Reserve Capacity rating mean and how does it apply to cycle?
Reserve capacity is the number of minutes a battery can maintain a useful voltage under a 25 ampere discharge. The higher the minute rating, the greater the battery’s ability to run lights, pumps, inverters, and electronics for a longer period before recharging is necessary. The 25 Amp. Reserve Capacity Rating is more realistic than Amp-Hour or CCA as a measurement of capacity for deep cycle service. Batteries promoted on their high Cold Cranking Ratings are easy and inexpensive to build. The market is flooded with them, however their Reserve Capacity, Cycle Life (the number of discharges and charges the battery can deliver) and Service life are poor. Reserve Capacity is difficult and costly to engineer into a battery and requires higher quality cell materials.
What is discharge efficiency?
L'efficacité de décharge fait référence au rapport entre la puissance réelle et la capacité nominale lorsque la batterie se décharge à la tension de fin dans certaines conditions de décharge. Il est principalement affecté par des facteurs tels que le taux de décharge, la température ambiante, la résistance interne. Généralement, plus le taux de décharge est élevé, plus l'efficacité de décharge sera faible ; plus la température est basse, plus l'efficacité de décharge sera faible.
What is the difference between float and cycle applications?
Une application flottante nécessite que la batterie soit en charge constante avec une décharge occasionnelle. Les applications de cycle chargent et déchargent régulièrement la batterie.

UN: La capacité de la batterie fait référence à la quantité d'électricité que le matériau actif de la batterie peut participer à la réaction électrochimique est appelée la capacité de la batterie, c'est-à-dire la quantité de charge que la batterie peut contenir après la charge. L'unité est « Ah » (Ah) et 1 A (A). Le courant est déchargé pendant 1 heure et la capacité est de 1 ampère heure (Ah). En supposant que le courant moyen est de 4A, le temps de décharge est de 3 heures lorsque la batterie est déchargée à la tension de terminaison de la batterie, et la capacité de la batterie est de 12Ah (la décharge n'est pas calculée ici) efficacité).
UN: Il fait référence à la résistance au courant traversant la batterie lorsque la batterie fonctionne. Il y a deux parties : la résistance interne ohmique et la résistance interne de polarisation. Une grande résistance interne de la batterie entraînera une diminution de la tension de fonctionnement de décharge de la batterie et raccourcira le temps de décharge. La résistance interne est principalement affectée par le matériau de la batterie, le processus de fabrication, la structure de la batterie et d'autres facteurs.

UN: Bien que la batterie au plomb ait été rigoureusement sélectionnée à sa sortie d'usine, après un certain temps d'utilisation, la non-uniformité apparaîtra et augmentera progressivement. Le chargeur ne peut pas reconnaître ou compléter la sous-charge. Comment équilibrer la capacité de la batterie ? Elle doit être réalisée par des humains. L'utilisateur mesure la tension en circuit ouvert de chaque batterie périodiquement et irrégulièrement pendant les périodes intermédiaires et tardives d'utilisation de la batterie. Pour les tensions inférieures, rechargez séparément pour rendre la tension et la capacité cohérentes avec les autres batteries et essayez de réduire leur écart.

UN: Vous avez peut-être entendu dire "vous avez besoin d'un chargeur à 3 étapes". Nous l'avons dit, et nous le redirons. Le meilleur type de chargeur à utiliser sur votre batterie est un chargeur à 3 étapes. Ils sont aussi appelés « chargeurs intelligents » ou « chargeurs contrôlés par microprocesseur ». Fondamentalement, ces types de chargeurs sont sûrs, faciles à utiliser et ne surchargeront pas votre batterie. Presque tous les chargeurs que nous vendons sont des chargeurs à 3 étages. D'accord, il est donc difficile de nier que les chargeurs à 3 étages fonctionnent et ils fonctionnent bien. Mais voici la question à un million de dollars : quelles sont les 3 étapes ? Qu'est-ce qui rend ces chargeurs si différents et efficaces ? ça en vaut vraiment la peine? Découvrons-le en parcourant chaque étape, une par une :
Étape 1 | Charge groupée
Le but principal d'un chargeur de batterie est de recharger une batterie. Cette première étape est généralement celle où la tension et l'ampérage les plus élevés pour lesquels le chargeur est conçu seront réellement utilisés. Le niveau de charge qui peut être appliqué sans surchauffer la batterie est appelé taux d'absorption naturel de la batterie. Pour une batterie AGM typique de 12 volts, la tension de charge entrant dans une batterie atteindra 14,6-14,8 volts, tandis que les batteries inondées peuvent être encore plus élevées. Pour la batterie au gel, la tension ne doit pas dépasser 14,2-14,3 volts. Si le chargeur est un chargeur de 10 ampères et si la résistance de la batterie le permet, le chargeur fournira 10 ampères complets. Cette étape rechargera les batteries qui sont fortement épuisées. Il n'y a aucun risque de surcharge à ce stade car la batterie n'est même pas encore pleine.
Étape 2 | Frais d'absorption
Les chargeurs intelligents détectent la tension et la résistance de la batterie avant la charge. Après avoir lu la batterie, le chargeur détermine à quelle étape charger correctement. Une fois que la batterie a atteint l'état de charge 80%*, le chargeur entrera en phase d'absorption. À ce stade, la plupart des chargeurs maintiendront une tension constante, tandis que l'ampérage diminue. Le courant plus faible entrant dans la batterie augmente en toute sécurité la charge de la batterie sans la surchauffer.
Cette étape prend plus de temps. Par exemple, le dernier 20% restant de la batterie prend beaucoup plus de temps que le premier 20% pendant la phase de masse. Le courant diminue continuellement jusqu'à ce que la batterie atteigne presque sa pleine capacité.
* L'état de charge réel L'étape d'absorption entrera variera d'un chargeur à l'autre
Étape 3 | Charge flottante
Certains chargeurs entrent en mode flottant dès l'état de charge 85%, mais d'autres commencent plus près de 95%. Dans tous les cas, l'étage flottant amène la batterie à fond et maintient l'état de charge du 100%. La tension diminuera et se maintiendra à un niveau constant de 13,2 à 13,4 volts, ce qui est le tension maximale qu'une batterie de 12 volts peut supporter. Le courant diminuera également à un point où il est considéré comme un filet. C'est de là que vient le terme "chargeur d'entretien". C'est essentiellement l'étape de flottement où il y a une charge dans la batterie à tout moment, mais seulement à un rythme sûr pour assurer un état de charge complet et rien de plus. La plupart des chargeurs intelligents ne s'éteignent pas à ce stade, mais il est tout à fait sûr de laisser une batterie en mode flottant pendant des mois, voire des années à la fois.
C'est la chose la plus saine pour une batterie d'être à l'état de charge 100%.
Nous l'avons déjà dit et nous le répéterons. Le meilleur type de chargeur à utiliser sur une batterie est un Chargeur intelligent à 3 étapes. Ils sont faciles à utiliser et sans souci. Vous n'avez jamais à vous soucier de laisser le chargeur sur la batterie trop longtemps. En fait, c'est mieux si vous le laissez allumé. Lorsqu'une batterie n'est pas complètement chargée, des cristaux de sulfate s'accumulent sur les plaques, ce qui vous prive d'énergie. Si vous laissez vos sports motorisés dans le cabanon pendant la saison morte ou pour les vacances, veuillez connecter la batterie à un chargeur à 3 étapes. Cela garantira que votre batterie sera prête à démarrer quand vous le serez.
UN: La décharge excessive est un problème qui provient d'une capacité insuffisante de la batterie, ce qui entraîne une surcharge des batteries. Les décharges plus profondes que 50% (en réalité bien en dessous de 12,0 Volts ou 1.200 Gravité Spécifique) raccourcissent considérablement la durée de vie d'une batterie sans augmenter la profondeur de cycle utilisable. Une recharge peu fréquente ou inadéquate peut également provoquer des symptômes de décharge excessive appelés SULFATION. Bien que l'équipement de charge se régule correctement, les symptômes de décharge excessive se manifestent par une perte de capacité de la batterie et une gravité spécifique inférieure à la normale. Le sulfate se produit lorsque le soufre de l'électrolyte se combine avec le plomb sur les plaques et forme du sulfate de plomb. Une fois que cette condition se produit, les chargeurs de batterie marine n'enlèveront pas le sulfate durci. Le sulfate peut généralement être éliminé par une charge de désulfatation ou d'égalisation appropriée avec des chargeurs de batterie manuels externes. Pour accomplir cette tâche, les batteries à plaques inondées doivent être chargées entre 6 et 10 ampères. à 2,4 à 2,5 volts par cellule jusqu'à ce que toutes les cellules dégagent librement du gaz et que leur gravité spécifique revienne à leur pleine concentration de charge. Les batteries AGM scellées doivent être amenées à 2,35 volts par cellule, puis déchargées à 1,75 volts par cellule, puis ce processus doit être répété jusqu'à ce que la capacité revienne à la batterie. Les batteries au gel peuvent ne pas récupérer. Dans la plupart des cas, la batterie peut être retournée pour compléter sa durée de vie. CHARGE Les alternateurs et les chargeurs de batterie flottants, y compris les chargeurs photovoltaïques régulés, ont des commandes automatiques qui diminuent le taux de charge à mesure que les batteries se chargent. Il convient de noter qu'une diminution à quelques ampères pendant la charge ne signifie pas que les batteries ont été complètement chargées. Les chargeurs de batterie sont de trois types. Il y a le type manuel, le type d'entretien et le type de commutateur automatique.
UN: Les piles primaires sont des piles sèches ordinaires, ne peuvent être utilisées qu'une seule fois. Les batteries secondaires sont également appelées batteries rechargeables, elles peuvent être chargées et déchargées plusieurs fois. Nos batteries sont des batteries secondaires.
UN: La cote de batterie la plus courante est la cote AMP-HOUR. Il s'agit d'une unité de mesure de la capacité de la batterie, obtenue en multipliant un flux de courant en ampères par le temps en heures de décharge. (Exemple : une batterie qui délivre 5 ampères pendant 20 heures délivre 5 ampères fois 20 heures, soit 100 ampères-heures.)
Les fabricants utilisent différentes périodes de décharge pour produire un Amp-Hr différent. Note pour les batteries de même capacité, donc, l'Amp-Hr. La notation a peu d'importance à moins d'être qualifiée par le nombre d'heures pendant lesquelles la batterie est déchargée. Pour cette raison, les ampères-heures ne sont qu'une méthode générale d'évaluation de la capacité d'une batterie à des fins de sélection. La qualité des composants internes et la construction technique de la batterie généreront différentes caractéristiques souhaitées sans affecter son indice d'ampère-heure. Par exemple, il y a des batteries de 150 ampères-heures qui ne supporteront pas une charge électrique pendant la nuit et si elles sont appelées à le faire de manière répétitive, elles tomberont en panne au début de leur vie. À l'inverse, il existe des batteries de 150 ampères-heures qui feront fonctionner une charge électrique pendant plusieurs jours avant de devoir être rechargées et le feront pendant des années. Les valeurs nominales suivantes doivent être examinées afin d'évaluer et de sélectionner la batterie appropriée pour une application spécifique : L'AMPÉRAGE DE DÉMARRAGE À FROID et LA CAPACITÉ DE RÉSERVE sont des valeurs nominales utilisées par l'industrie pour simplifier la sélection de la batterie.
UN: La capacité de réserve est le nombre de minutes pendant lesquelles une batterie peut maintenir une tension utile sous une décharge de 25 ampères. Plus la cote de la minute est élevée, plus la capacité de la batterie à faire fonctionner les lumières, les pompes, les onduleurs et les appareils électroniques pendant une longue période avant qu'une recharge ne soit nécessaire est grande. Le 25 ampères. L'évaluation de la capacité de réserve est plus réaliste que l'ampère-heure ou le CCA en tant que mesure de la capacité pour le service à cycle profond. Les batteries promues sur leurs cotes de démarrage à froid élevées sont faciles et peu coûteuses à construire. Le marché en est inondé, mais leur capacité de réserve, leur cycle de vie (le nombre de décharges et de charges que la batterie peut fournir) et leur durée de vie sont médiocres. La capacité de réserve est difficile et coûteuse à intégrer dans une batterie et nécessite des matériaux de cellule de meilleure qualité.
UN: L'efficacité de décharge fait référence au rapport entre la puissance réelle et la capacité nominale lorsque la batterie se décharge à la tension de fin dans certaines conditions de décharge. Il est principalement affecté par des facteurs tels que le taux de décharge, la température ambiante, la résistance interne. Généralement, plus le taux de décharge est élevé, plus l'efficacité de décharge sera faible ; plus la température est basse, plus l'efficacité de décharge sera faible.
UN: Une application flottante nécessite que la batterie soit en charge constante avec une décharge occasionnelle. Les applications de cycle chargent et déchargent régulièrement la batterie.
A: Generally, they can last for several years to a decade or more. The service life of lithium batteries varies depending on several factors. The lifespan is influenced by factors such as the quality of the battery, charging and discharging patterns, operating temperature, and the depth of discharge. High-quality lithium batteries with proper usage and maintenance tend to have longer lifespans.
A: There are several ways to determine if a lithium battery needs replacement
Monitor the battery’s capacity. If the battery doesn’t hold a charge as long as it used to and the performance significantly deteriorates, it might be time for a replacement.
If the battery shows signs of swelling or physical damage.
Frequent overheating or abnormal charging patterns could suggest that the battery is no longer functioning properly and requires replacement.

FAQ
Search battery, charging and product support questions.
What is the capacity of the battery?
The capacity of the battery refers to the amount of electricity that the active material in the battery can participate in the electrochemical reaction is called the capacity of the battery, that is, the amount of charge that the battery can hold after charging. The unit is “Ah” (Ah) and 1 A (A). The current is discharged for 1 hour, and the capacity is 1 ampere hour (Ah). Assuming that the average current is 4A, the discharge time is 3 hours when the battery is discharged at the termination voltage of the battery, and the battery capacity is 12Ah (the discharge is not calculated here) effectiveness).
What is battery internal resistance?
It refers to the resistance to the current flowing through the battery when the battery is working. There are two parts: ohmic internal resistance and polarization internal resistance. Large internal resistance of the battery will cause the battery’s discharge working voltage to decrease and shorten the discharge time. The internal resistance is mainly affected by the battery material, manufacturing process, battery structure and other factors. Is an important parameter to measure battery performance.
Can I fast charge my battery?
La charge rapide n'est pas recommandée car elle est nocive pour la batterie.
What are the reasons for the battery warming up during charging?
Pendant le processus de charge de la batterie, une partie de l'énergie électrique est convertie en énergie chimique et une partie de l'énergie électrique est convertie en énergie thermique et autre énergie. Il est normal que la batterie rechargeable chauffe, mais lorsque la température est trop élevée, vous devez vérifier si le courant de charge est trop important ou si un court-circuit se produit à l'intérieur de la batterie.
What is the battery's charge acceptance?
Dans les conditions de tension et de courant de charge spécifiées, la quantité de charge que la batterie accepte par unité de temps.
What is the harm of the battery heating?
La batterie est autorisée à avoir une petite quantité de chaleur, que ce soit en cours d'utilisation ou pendant la charge, mais une chaleur anormale n'est pas autorisée. La fièvre anormale est évidente et vous pouvez la sentir en touchant le boîtier de la batterie avec votre main. La chaleur est très nocive pour la batterie. La chaleur provoque d'abord l'évaporation et l'assèchement progressif de l'eau de l'électrolyte, puis diminue l'efficacité de la charge, la déformation des plaques, l'augmentation de la résistance interne, l'oxydation accélérée des pièces mécaniques, les plaques ou les séparateurs brûlés, et se manifeste enfin par une capacité réduite de la batterie et durée de vie raccourcie.
What is the danger if the connecting bolts are not tightened?
Une connexion desserrée entraînera une augmentation de la résistance au niveau de la connexion, ce qui provoquera facilement des étincelles lors de la charge et de la décharge. Dans les cas graves, cela provoquera de la chaleur et un incendie, et un accident se produira.
How to maintain the consistency of the battery pack?
Although the lead-acid battery has been strictly selected when it leaves the factory, after a certain period of use, the non-uniformity will appear and gradually increase. The charger can’t recognize or supplement the undercharge. How to balance the battery capacity? It must be performed by humans. The user measures the open circuit voltage of each battery periodically and irregularly during the middle and late periods of battery pack use. For lower voltages, recharge separately to make the voltage and capacity consistent with other batteries, and try to reduce their gap.
Can I do a partial replacement of my batteries?
Le remplacement partiel de la batterie des groupes de batteries au plomb-acide n'est pas recommandé.
Are you a battery manufacturer, and do you produce the plates by yourself ?
Oui, nous sommes un fabricant professionnel de batteries dans la province de Guandong, en Chine depuis 2003. Nous produisons des plaques de plomb par notre propre atelier.
Does your battery develop a memory?
Les batteries au plomb ne développent aucun type de mémoire. Cela signifie que vous n'avez pas besoin de décharger profondément ou de décharger complètement une batterie avant de la recharger. Pour une durée de vie et des performances optimales, nous recommandons généralement une décharge de 20 à 50% de la capacité nominale de la batterie, même si la batterie peut être cyclée à 90%.
How does temperature affect the performance of my batteries?
À des températures plus élevées (supérieures à 77 °F (25 °C)), la capacité de la batterie augmente généralement, généralement au détriment de la durée de vie de la batterie. Des températures plus élevées augmentent également la caractéristique d'autodécharge. Des températures plus froides (inférieures à 77º F (25º C)) réduiront la capacité de la batterie et prolongeront sa durée de vie. Des températures plus froides ralentiront l'auto-décharge. Par conséquent, faire fonctionner les batteries à des températures égales ou légèrement inférieures à 25 °C (77 °F) optimisera à la fois les performances et la durée de vie.
How to charge a battery to be at 100% state of charge healthiest?
You may have heard it said “you need a 3 stage charger”. We’ve said it, and we’ll say it again. The best kind of charger to use on your battery is a 3 stage charger. They are also called “smart chargers” or “micro processor controlled chargers”. Basically, these types of chargers are safe, easy to use, and will not overcharge your battery. Almost all of the chargers we sell are 3 stage chargers. Okay, so it’s hard to deny that 3 stage chargers work and they work well. But here’s the million dollar question: What are the 3 stages? What makes these chargers so different and efficient? Is it really worth it? Lets find out by going through each stage, one by one:Stage 1 | Bulk ChargeThe primary purpose of a battery charger is to recharge a battery. This first stage is typically where the highest voltage and amperage the charger is rated for will actually be used. The level of charge that can be applied without overheating the battery is known as the battery’s natural absorption rate. For a typical 12 volt AGM battery, the charging voltage going into a battery will reach 14.6-14.8 volts, while flooded batteries can be even higher. For the gel battery, the voltage should be no more than 14.2-14.3 volts. If the charger is a 10 amp charger, and if the battery resistance allows for it, the charger will put out a full 10 amps. This stage will recharge batteries that are severely drained. There is no risk of overcharging in this stage because the battery hasn’t even reached full yet. Stage 2 | Absorption ChargeSmart chargers will detect voltage and resistance from the battery prior to charging. After reading the battery the charger determines which stage to properly charge at. Once the battery has reached 80%* state of charge, the charger will enter the absorption stage. At this point most chargers will maintain a steady voltage, while the amperage declines. The lower current going into the battery safely brings up the charge on the battery without overheating it.This stage takes more time. For instance, the last remaining 20% of the battery takes much longer when compared to the first 20% during the bulk stage. The current continuously declines until the battery almost reaches full capacity.*Actual state of charge Absorption Stage will enter will vary from charger to chargerStage 3 | Float ChargeSome chargers enter float mode as early as 85% state of charge but others begin closer to 95%. Either way, the float stage brings the battery all the way through and maintains the 100% state of charge. The voltage will taper down and maintain at a steady 13.2-13.4 volts, which is the maximum voltage a 12 volt battery can hold. The current will also decrease to a point where it’s considered a trickle. That’s where the term “trickle charger” comes from. It’s essentially the float stage where there is charge going into the battery at all times, but only at a safe rate to ensure a full state of charge and nothing more. Most smart chargers do not turn off at this point, yet it is completely safe to leave a battery in float mode for months to even years at a time. It’s the healthiest thing for a battery to be at 100% state of charge. We’ve said it before and we’ll say it again. The best kind of charger to use on a battery is a 3 stage smart charger. They are easy to use and worry free. You don’t ever have to worry about leaving the charger on the battery for too long. In fact, it’s best if you DO leave it on. When a battery is not at a fully charged state, sulfate crystal build on the plates and this robs you of power. If you leave your powersports in the shed during off-season or for vacations, please connect the battery to a 3 stage charger. This will ensure that your battery will be ready to start whenever you are.
Does over-discharging damage batteries?
Over-discharging is a problem which originates from insufficient battery capacity causing the batteries to be overworked. Discharges deeper than 50% (in reality well below 12.0 Volts or 1.200 Specific Gravity) significantly shorten the Cycle Life of a battery without increasing the usable depth of cycle. Infrequent or inadequate recharging can also cause over discharging symptoms called SULFATION. Despite that charging equipment is regulating back properly, over discharging symptoms are displayed as loss of battery capacity and lower than normal specific gravity. Sulfate occurs when sulfur from the electrolyte combines with the lead on the plates and forms lead-sulfate. Once this condition becomes occurs, marine battery chargers will not remove the hardened sulfate. Sulfate can usually be removed by a proper desulfation or equalization charge with external manual battery chargers. To accomplish this task, the flooded plate batteries must be charged at 6 to 10 amps. at 2.4 to 2.5 volts per cell until all cells are gassing freely and their specific gravity returns to their full charge concentration. Sealed AGM batteries should be brought to 2.35 volts per cell and then discharged to 1.75 volts per cell and then this process must be repeated until the capacity returns to the battery. Gel batteries may not recover. In most cases, the battery may be returned to complete its service life.CHARGING Alternators and float battery chargers including regulated photo voltaic chargers have automatic controls which taper the charge rate as the batteries come up in charge. It should be noted that a decrease to a few amperes while charging does not mean that the batteries have been fully charged. Battery chargers are of three types. There is the manual type, the trickle type, and the automatic switcher type.
What are primary and secondary batteries?
Les piles primaires sont des piles sèches ordinaires, ne peuvent être utilisées qu'une seule fois. Les batteries secondaires sont également appelées batteries rechargeables, elles peuvent être chargées et déchargées plusieurs fois. Nos batteries sont des batteries secondaires.
What is battery rating?
The most common battery rating is the AMP-HOUR RATING. This is a unit of measurement for battery capacity, obtained by multiplying a current flow in amperes by the time in hours of discharge. (Example: A battery which delivers 5 amperes for 20 hours delivers 5 amperes times 20 hours, or 100 ampere-hours.)Manufacturers use different discharge periods to yield an different Amp-Hr. Rating for the same capacity batteries, therefore, the Amp-Hr. Rating has little significance unless qualified by the number of hours the battery is discharged. For this reason Amp-Hour Ratings are only a general method of evaluating a battery’s capacity for selection purposes. The quality of internal components and technical construction within the battery will generate different desired characteristics without effecting its Amp-Hour Rating. For instance, there are 150 Amp-Hour batteries that will not support an electrical load overnight and if called upon to do so repetitively, will fail early in their life. Conversely, there are 150 Amp-Hour batteries that will operate an electrical load for several days before needing recharging and will do so for years. The following ratings must be examined in order to evaluate and select the proper battery for a specific application: COLD CRANKING AMPERAGE and RESERVE CAPACITY are ratings used by the industry to simplify battery selection.
What does the Reserve Capacity rating mean and how does it apply to cycle?
Reserve capacity is the number of minutes a battery can maintain a useful voltage under a 25 ampere discharge. The higher the minute rating, the greater the battery’s ability to run lights, pumps, inverters, and electronics for a longer period before recharging is necessary. The 25 Amp. Reserve Capacity Rating is more realistic than Amp-Hour or CCA as a measurement of capacity for deep cycle service. Batteries promoted on their high Cold Cranking Ratings are easy and inexpensive to build. The market is flooded with them, however their Reserve Capacity, Cycle Life (the number of discharges and charges the battery can deliver) and Service life are poor. Reserve Capacity is difficult and costly to engineer into a battery and requires higher quality cell materials.
What is discharge efficiency?
L'efficacité de décharge fait référence au rapport entre la puissance réelle et la capacité nominale lorsque la batterie se décharge à la tension de fin dans certaines conditions de décharge. Il est principalement affecté par des facteurs tels que le taux de décharge, la température ambiante, la résistance interne.
