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?
Schnellladen wird nicht empfohlen, da es schädlich für den Akku ist.
What are the reasons for the battery warming up during charging?
Beim Ladevorgang der Batterie wird ein Teil der elektrischen Energie in chemische Energie und ein Teil der elektrischen Energie in Wärmeenergie und andere Energie umgewandelt. Eine Erwärmung des Akkus ist normal, bei zu hoher Temperatur sollten Sie jedoch prüfen, ob der Ladestrom zu groß ist oder ein Kurzschluss im Inneren des Akkus auftritt.
What is the battery's charge acceptance?
Die Ladungsmenge, die die Batterie unter den angegebenen Ladespannungs- und Strombedingungen pro Zeiteinheit aufnimmt.
What is the harm of the battery heating?
Der Akku darf sich während des Gebrauchs oder während des Ladevorgangs leicht erhitzen, aber ungewöhnliche Hitze ist nicht zulässig. Das abnormale Fieber ist offensichtlich und Sie können es fühlen, indem Sie das Batteriegehäuse mit Ihrer Hand berühren. Hitze ist sehr schädlich für die Batterie. Die Hitze führt zunächst zum Verdampfen und allmählichen Austrocknen des Elektrolytwassers und verringert dann die Ladeeffizienz, Verformung der Platten, erhöhten Innenwiderstand, beschleunigte Oxidation mechanischer Teile, durchgebrannte Platten oder Separatoren und äußert sich schließlich in einer verringerten Batteriekapazität und verkürztes Leben.
What is the danger if the connecting bolts are not tightened?
Eine lockere Verbindung erhöht den Widerstand an der Verbindung, wodurch beim Laden und Entladen leicht Funken entstehen. In schweren Fällen verursacht es Hitze und Feuer und es kommt zu einem Unfall.
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?
Ein teilweiser Batterieaustausch von Blei-Säure-Batteriebänken wird nicht empfohlen.
Are you a battery manufacturer, and do you produce the plates by yourself ?
Ja, wir sind seit 2003 ein professioneller Batteriehersteller in der Provinz Guandong, China. Wir produzieren Bleiplatten in unserer eigenen Werkstatt.
Does your battery develop a memory?
Bleibatterien entwickeln keinerlei Gedächtnis. Das bedeutet, dass Sie einen Akku nicht tiefentladen oder vollständig entladen müssen, bevor Sie ihn wieder aufladen. Für eine optimale Lebensdauer und Leistung empfehlen wir im Allgemeinen eine Entladung von 20 bis 501 TP3T der Nennkapazität der Batterien, auch wenn die Batterie bis zu 901 TP3T zykliert werden kann.
How does temperature affect the performance of my batteries?
Bei höheren Temperaturen (über 25 °C) nimmt die Batteriekapazität im Allgemeinen zu, normalerweise auf Kosten der Batterielebensdauer. Höhere Temperaturen erhöhen auch die Selbstentladungscharakteristik. Kältere Temperaturen (unter 25 °C) verringern die Batteriekapazität und verlängern die Batterielebensdauer. Kühlere Temperaturen verlangsamen die Selbstentladung. Daher optimiert der Betrieb von Batterien bei Temperaturen von 77º F (25º C) oder etwas darunter sowohl die Leistung als auch die Lebensdauer.
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?
Primärbatterien sind gewöhnliche Trockenbatterien, die nur einmal verwendet werden können. Sekundärbatterien werden auch wiederaufladbare Batterien genannt, können für viele Zeit geladen und entladen werden. Unsere Batterien sind Sekundärbatterien.
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?
Die Entladeeffizienz bezieht sich auf das Verhältnis der tatsächlichen Leistung zur Nennkapazität, wenn die Batterie unter bestimmten Entladebedingungen bei der Endspannung entladen wird. Es wird hauptsächlich von Faktoren wie Entladungsrate, Umgebungstemperatur, Innenwiderstand beeinflusst. Allgemein gilt, je höher die Entladungsrate ist, desto geringer wird die Entladungseffizienz sein; Je niedriger die Temperatur ist, desto geringer ist die Entladungseffizienz.
What is the difference between float and cycle applications?
Eine Float-Anwendung erfordert eine konstante Ladung der Batterie mit gelegentlicher Entladung. Zyklusanwendungen laden und entladen den Akku regelmäßig.

A: Die Kapazität der Batterie bezieht sich auf die Strommenge, die das aktive Material in der Batterie an der elektrochemischen Reaktion beteiligen kann, die als Kapazität der Batterie bezeichnet wird, dh die Ladungsmenge, die die Batterie nach dem Laden halten kann. Die Einheit ist „Ah“ (Ah) und 1 A (A). Der Strom wird 1 Stunde lang entladen und die Kapazität beträgt 1 Amperestunde (Ah). Unter der Annahme, dass der durchschnittliche Strom 4 A beträgt, beträgt die Entladezeit 3 Stunden, wenn die Batterie bei der Abschlussspannung der Batterie entladen wird, und die Batteriekapazität beträgt 12 Ah (die Entladung wird hier nicht berechnet).
A: Es bezieht sich auf den Widerstand gegen den Strom, der durch die Batterie fließt, wenn die Batterie arbeitet. Es gibt zwei Teile: Ohmscher Innenwiderstand und Polarisationsinnenwiderstand. Ein großer Innenwiderstand der Batterie führt dazu, dass die Entladebetriebsspannung der Batterie abnimmt und die Entladezeit verkürzt wird. Der Innenwiderstand wird hauptsächlich durch das Batteriematerial, den Herstellungsprozess, die Batteriestruktur und andere Faktoren beeinflusst. Ist ein wichtiger Parameter zur Messung der Batterieleistung.
A: Beim Ladevorgang der Batterie wird ein Teil der elektrischen Energie in chemische Energie und ein Teil der elektrischen Energie in Wärmeenergie und andere Energie umgewandelt. Eine Erwärmung des Akkus ist normal, bei zu hoher Temperatur sollten Sie jedoch prüfen, ob der Ladestrom zu groß ist oder ein Kurzschluss im Inneren des Akkus auftritt.
A: Der Akku darf sich während des Gebrauchs oder während des Ladevorgangs leicht erhitzen, aber ungewöhnliche Hitze ist nicht zulässig. Das abnormale Fieber ist offensichtlich und Sie können es fühlen, indem Sie das Batteriegehäuse mit Ihrer Hand berühren. Hitze ist sehr schädlich für die Batterie. Die Hitze führt zunächst zum Verdampfen und allmählichen Austrocknen des Elektrolytwassers und verringert dann die Ladeeffizienz, Verformung der Platten, erhöhten Innenwiderstand, beschleunigte Oxidation mechanischer Teile, durchgebrannte Platten oder Separatoren und äußert sich schließlich in einer verringerten Batteriekapazität und verkürztes Leben.
A: Eine lockere Verbindung erhöht den Widerstand an der Verbindung, wodurch beim Laden und Entladen leicht Funken entstehen. In schweren Fällen verursacht es Hitze und Feuer und es kommt zu einem Unfall.
A: Obwohl die Blei-Säure-Batterie beim Verlassen des Werks streng ausgewählt wurde, tritt nach einer gewissen Nutzungsdauer die Ungleichmäßigkeit auf und nimmt allmählich zu. Das Ladegerät kann die Unterladung nicht erkennen oder ergänzen. Wie gleicht man die Batteriekapazität aus? Sie muss von Menschen ausgeführt werden. Der Benutzer misst die Leerlaufspannung jeder Batterie periodisch und unregelmäßig während der mittleren und späten Nutzungsperioden des Batteriepacks. Laden Sie bei niedrigeren Spannungen separat auf, um die Spannung und Kapazität mit anderen Batterien in Einklang zu bringen, und versuchen Sie, ihre Lücke zu verringern.
A: Ja, wir sind seit 2003 ein professioneller Batteriehersteller in der Provinz Guandong, China. Wir produzieren Bleiplatten in unserer eigenen Werkstatt.
A: Bleibatterien entwickeln keinerlei Gedächtnis. Das bedeutet, dass Sie einen Akku nicht tiefentladen oder vollständig entladen müssen, bevor Sie ihn wieder aufladen. Für eine optimale Lebensdauer und Leistung empfehlen wir im Allgemeinen eine Entladung von 20 bis 501 TP3T der Nennkapazität der Batterien, auch wenn die Batterie bis zu 901 TP3T zykliert werden kann.
A: Bei höheren Temperaturen (über 25 °C) nimmt die Batteriekapazität im Allgemeinen zu, normalerweise auf Kosten der Batterielebensdauer. Höhere Temperaturen erhöhen auch die Selbstentladungscharakteristik. Kältere Temperaturen (unter 25 °C) verringern die Batteriekapazität und verlängern die Batterielebensdauer. Kühlere Temperaturen verlangsamen die Selbstentladung. Daher optimiert der Betrieb von Batterien bei Temperaturen von 77º F (25º C) oder etwas darunter sowohl die Leistung als auch die Lebensdauer.
A: Vielleicht haben Sie schon einmal gehört, dass gesagt wird: „Sie brauchen ein 3-Stufen-Ladegerät“. Wir haben es gesagt, und wir werden es noch einmal sagen. Das beste Ladegerät für Ihre Batterie ist ein 3-Stufen-Ladegerät. Sie werden auch „intelligente Ladegeräte“ oder „mikroprozessorgesteuerte Ladegeräte“ genannt. Grundsätzlich sind diese Arten von Ladegeräten sicher, einfach zu bedienen und überladen Ihren Akku nicht. Fast alle von uns verkauften Ladegeräte sind 3-Stufen-Ladegeräte. Okay, es ist schwer zu leugnen, dass 3-Stufen-Ladegeräte funktionieren, und sie funktionieren gut. Aber hier ist die Millionen-Dollar-Frage: Was sind die 3 Stufen? Was macht diese Ladegeräte so anders und effizient? Lohnt es sich wirklich? Finden wir es heraus, indem wir jede Phase einzeln durchgehen:
Stufe 1 | Massenladung
Der Hauptzweck eines Batterieladegeräts besteht darin, eine Batterie aufzuladen. In dieser ersten Phase wird normalerweise die höchste Spannung und Stromstärke verwendet, für die das Ladegerät ausgelegt ist. Der Ladezustand, der aufgebracht werden kann, ohne die Batterie zu überhitzen, wird als natürliche Absorptionsrate der Batterie bezeichnet. Bei einer typischen 12-Volt-AGM-Batterie erreicht die in eine Batterie eingehende Ladespannung 14,6–14,8 Volt, während geflutete Batterien sogar noch höher sein können. Für die Gel-Batterie sollte die Spannung nicht mehr als 14,2-14,3 Volt betragen. Wenn das Ladegerät ein 10-Ampere-Ladegerät ist und der Batteriewiderstand dies zulässt, gibt das Ladegerät volle 10 Ampere aus. In dieser Phase werden stark entladene Batterien wieder aufgeladen. In dieser Phase besteht keine Gefahr des Überladens, da der Akku noch nicht einmal voll ist.
Stufe 2 | Absorptionsladung
Intelligente Ladegeräte erkennen vor dem Laden Spannung und Widerstand der Batterie. Nach dem Lesen des Akkus bestimmt das Ladegerät, in welcher Phase es richtig geladen werden soll. Sobald die Batterie den Ladezustand 80%* erreicht hat, tritt das Ladegerät in die Absorptionsphase ein. An diesem Punkt halten die meisten Ladegeräte eine konstante Spannung aufrecht, während die Stromstärke abnimmt. Der niedrigere Strom, der in die Batterie fließt, bringt die Batterie sicher auf, ohne sie zu überhitzen.
Diese Phase dauert länger. Beispielsweise benötigt das letzte verbleibende 20% der Batterie im Vergleich zum ersten 20% während der Bulk-Phase viel länger. Der Strom nimmt kontinuierlich ab, bis die Batterie fast ihre volle Kapazität erreicht hat.
*Der tatsächliche Ladezustand der Absorptionsphase ist von Ladegerät zu Ladegerät unterschiedlich
Stufe 3 | Erhaltungsladung
Einige Ladegeräte wechseln bereits beim Ladezustand des 85% in den Float-Modus, andere beginnen näher am 95%. In jedem Fall bringt die Float-Stufe die Batterie vollständig durch und hält den Ladezustand des 100% aufrecht. Die Spannung wird sich verjüngen und bei konstanten 13,2-13,4 Volt bleiben, was das ist maximale Spannung, die eine 12-Volt-Batterie halten kann. Der Strom nimmt auch bis zu einem Punkt ab, an dem er als Rinnsal angesehen wird. Daher stammt auch der Begriff „Erhaltungsladegerät“. Es ist im Wesentlichen die Float-Phase, in der die Batterie jederzeit aufgeladen wird, jedoch nur mit einer sicheren Geschwindigkeit, um einen vollen Ladezustand zu gewährleisten, und nicht mehr. Die meisten intelligenten Ladegeräte schalten sich zu diesem Zeitpunkt nicht aus, aber es ist absolut sicher, eine Batterie monate- oder sogar jahrelang im Float-Modus zu belassen.
Es ist das Gesündeste für eine Batterie, einen Ladezustand von 100% zu haben.
Wir haben es schon einmal gesagt und wir werden es noch einmal sagen. Die beste Art von Ladegerät für eine Batterie ist ein 3-Stufen-Smart-Ladegerät. Sie sind einfach zu bedienen und sorgenfrei. Sie müssen sich keine Sorgen machen, das Ladegerät zu lange am Akku zu lassen. Tatsächlich ist es am besten, wenn Sie es eingeschaltet lassen. Wenn eine Batterie nicht vollständig aufgeladen ist, bilden sich Sulfatkristalle auf den Platten und dies raubt Ihnen die Energie. Wenn Sie Ihren Powersport außerhalb der Saison oder im Urlaub im Schuppen lassen, schließen Sie den Akku bitte an ein 3-Stufen-Ladegerät an. Dadurch wird sichergestellt, dass Ihre Batterie startbereit ist, wann immer Sie es sind.
A: Überentladung ist ein Problem, das von einer unzureichenden Batteriekapazität herrührt, die eine Überlastung der Batterien verursacht. Entladungen tiefer als 50% (in Wirklichkeit weit unter 12,0 Volt oder 1.200 spezifischem Gewicht) verkürzen die Lebensdauer einer Batterie erheblich, ohne die nutzbare Zyklustiefe zu erhöhen. Seltenes oder unzureichendes Aufladen kann auch zu Überentladungssymptomen führen, die als SULFATION bezeichnet werden. Obwohl die Ladeausrüstung ordnungsgemäß zurückregelt, werden Überentladungssymptome als Verlust der Batteriekapazität und niedriger als das normale spezifische Gewicht angezeigt. Sulfat entsteht, wenn sich Schwefel aus dem Elektrolyten mit dem Blei auf den Platten verbindet und Bleisulfat bildet. Sobald diese Bedingung eintritt, werden Schiffsbatterieladegeräte das gehärtete Sulfat nicht mehr entfernen. Sulfat kann normalerweise durch eine ordnungsgemäße Desulfatierung oder Ausgleichsladung mit externen manuellen Batterieladegeräten entfernt werden. Um diese Aufgabe zu erfüllen, müssen die gefluteten Plattenbatterien mit 6 bis 10 Ampere geladen werden. bei 2,4 bis 2,5 Volt pro Zelle, bis alle Zellen frei gasen und ihr spezifisches Gewicht zu ihrer vollen Ladungskonzentration zurückkehrt. Versiegelte AGM-Batterien sollten auf 2,35 Volt pro Zelle gebracht und dann auf 1,75 Volt pro Zelle entladen werden, und dann muss dieser Vorgang wiederholt werden, bis die Kapazität der Batterie zurückkehrt. Gel-Batterien erholen sich möglicherweise nicht. In den meisten Fällen kann die Batterie zurückgegeben werden, um ihre Lebensdauer zu vervollständigen. LADEN Lichtmaschinen und Float-Batterieladegeräte, einschließlich geregelter Photovoltaik-Ladegeräte, verfügen über automatische Steuerungen, die die Laderate verringern, wenn die Batterien aufgeladen werden. Zu beachten ist, dass ein Absinken auf wenige Ampere während des Ladevorgangs nicht bedeutet, dass die Akkus vollständig geladen sind. Es gibt drei Arten von Batterieladegeräten. Es gibt den manuellen Typ, den Trickle-Typ und den automatischen Switcher-Typ.
A: Primärbatterien sind gewöhnliche Trockenbatterien, die nur einmal verwendet werden können. Sekundärbatterien werden auch wiederaufladbare Batterien genannt, können für viele Zeit geladen und entladen werden. Unsere Batterien sind Sekundärbatterien.
A: Die gebräuchlichste Batteriebewertung ist die AMP-HOUR RATING. Dies ist eine Maßeinheit für die Batteriekapazität, die durch Multiplikation eines Stromflusses in Ampere mit der Entladezeit in Stunden erhalten wird. (Beispiel: Eine Batterie, die 20 Stunden lang 5 Ampere liefert, liefert 5 Ampere mal 20 Stunden oder 100 Amperestunden.)
Hersteller verwenden unterschiedliche Entladezeiten, um unterschiedliche Amperestunden zu erhalten. Wertung für Akkus gleicher Kapazität, daher die Amp-Hr. Die Bewertung hat nur geringe Bedeutung, wenn sie nicht durch die Anzahl der Stunden, in denen die Batterie entladen ist, qualifiziert wird. Aus diesem Grund sind Amperestundenwerte nur eine allgemeine Methode zur Bewertung der Kapazität einer Batterie für Auswahlzwecke. Die Qualität der internen Komponenten und der technische Aufbau innerhalb der Batterie erzeugen unterschiedliche gewünschte Eigenschaften, ohne die Amperestunden-Bewertung zu beeinflussen. Beispielsweise gibt es 150-Ampere-Stunden-Batterien, die eine elektrische Last über Nacht nicht unterstützen und bei wiederholter Aufforderung früh in ihrer Lebensdauer versagen. Umgekehrt gibt es 150-Ah-Batterien, die mehrere Tage lang eine elektrische Last betreiben, bevor sie aufgeladen werden müssen, und dies über Jahre. Die folgenden Werte müssen geprüft werden, um die richtige Batterie für eine bestimmte Anwendung zu bewerten und auszuwählen: COLD CRANKING AMPERAGE und RESERVE CAPACITY sind Werte, die von der Industrie verwendet werden, um die Batterieauswahl zu vereinfachen.

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?
Schnellladen wird nicht empfohlen, da es schädlich für den Akku ist.
What are the reasons for the battery warming up during charging?
Beim Ladevorgang der Batterie wird ein Teil der elektrischen Energie in chemische Energie und ein Teil der elektrischen Energie in Wärmeenergie und andere Energie umgewandelt. Eine Erwärmung des Akkus ist normal, bei zu hoher Temperatur sollten Sie jedoch prüfen, ob der Ladestrom zu groß ist oder ein Kurzschluss im Inneren des Akkus auftritt.
What is the battery's charge acceptance?
Die Ladungsmenge, die die Batterie unter den angegebenen Ladespannungs- und Strombedingungen pro Zeiteinheit aufnimmt.
What is the harm of the battery heating?
Der Akku darf sich während des Gebrauchs oder während des Ladevorgangs leicht erhitzen, aber ungewöhnliche Hitze ist nicht zulässig. Das abnormale Fieber ist offensichtlich und Sie können es fühlen, indem Sie das Batteriegehäuse mit Ihrer Hand berühren. Hitze ist sehr schädlich für die Batterie. Die Hitze führt zunächst zum Verdampfen und allmählichen Austrocknen des Elektrolytwassers und verringert dann die Ladeeffizienz, Verformung der Platten, erhöhten Innenwiderstand, beschleunigte Oxidation mechanischer Teile, durchgebrannte Platten oder Separatoren und äußert sich schließlich in einer verringerten Batteriekapazität und verkürztes Leben.
What is the danger if the connecting bolts are not tightened?
Eine lockere Verbindung erhöht den Widerstand an der Verbindung, wodurch beim Laden und Entladen leicht Funken entstehen. In schweren Fällen verursacht es Hitze und Feuer und es kommt zu einem Unfall.
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?
Ein teilweiser Batterieaustausch von Blei-Säure-Batteriebänken wird nicht empfohlen.
Are you a battery manufacturer, and do you produce the plates by yourself ?
Ja, wir sind seit 2003 ein professioneller Batteriehersteller in der Provinz Guandong, China. Wir produzieren Bleiplatten in unserer eigenen Werkstatt.
Does your battery develop a memory?
Bleibatterien entwickeln keinerlei Gedächtnis. Das bedeutet, dass Sie einen Akku nicht tiefentladen oder vollständig entladen müssen, bevor Sie ihn wieder aufladen. Für eine optimale Lebensdauer und Leistung empfehlen wir im Allgemeinen eine Entladung von 20 bis 501 TP3T der Nennkapazität der Batterien, auch wenn die Batterie bis zu 901 TP3T zykliert werden kann.
How does temperature affect the performance of my batteries?
Bei höheren Temperaturen (über 25 °C) nimmt die Batteriekapazität im Allgemeinen zu, normalerweise auf Kosten der Batterielebensdauer. Höhere Temperaturen erhöhen auch die Selbstentladungscharakteristik. Kältere Temperaturen (unter 25 °C) verringern die Batteriekapazität und verlängern die Batterielebensdauer. Kühlere Temperaturen verlangsamen die Selbstentladung. Daher optimiert der Betrieb von Batterien bei Temperaturen von 77º F (25º C) oder etwas darunter sowohl die Leistung als auch die Lebensdauer.
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?
Primärbatterien sind gewöhnliche Trockenbatterien, die nur einmal verwendet werden können. Sekundärbatterien werden auch wiederaufladbare Batterien genannt, können für viele Zeit geladen und entladen werden. Unsere Batterien sind Sekundärbatterien.
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?
Die Entladeeffizienz bezieht sich auf das Verhältnis der tatsächlichen Leistung zur Nennkapazität, wenn die Batterie unter bestimmten Entladebedingungen bei der Endspannung entladen wird. Es wird hauptsächlich von Faktoren wie Entladungsrate, Umgebungstemperatur, Innenwiderstand beeinflusst. Allgemein gilt, je höher die Entladungsrate ist, desto geringer wird die Entladungseffizienz sein; Je niedriger die Temperatur ist, desto geringer ist die Entladungseffizienz.
