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?
Быстрая зарядка не рекомендуется, так как это вредно для аккумулятора.
What are the reasons for the battery warming up during charging?
В процессе зарядки аккумулятора часть электрической энергии преобразуется в химическую энергию, а часть электрической энергии преобразуется в тепловую энергию и другую энергию. Аккумуляторная батарея нагревается нормально, но если температура слишком высокая, следует проверить, не слишком ли велик зарядный ток и не произошло ли короткое замыкание внутри батареи.
What is the battery's charge acceptance?
При заданных условиях зарядного напряжения и тока количество заряда, которое батарея принимает в единицу времени.
What is the harm of the battery heating?
Аккумулятор может иметь небольшое количество тепла, независимо от того, используется ли он или во время зарядки, но чрезмерное нагревание не допускается. Аномальная лихорадка очевидна, и вы можете почувствовать ее, прикоснувшись к корпусу батареи рукой. Тепло очень вредно для батареи. Тепло сначала вызывает испарение и постепенное высыхание воды электролита, а затем снижает эффективность заряда, деформирует пластины, увеличивает внутреннее сопротивление, ускоряет окисление механических частей, выгорает пластины или сепараторы и, наконец, проявляется в снижении емкости аккумулятора и укороченная жизнь.
What is the danger if the connecting bolts are not tightened?
Плохое соединение приведет к увеличению сопротивления в месте соединения, что может легко вызвать искрение во время зарядки и разрядки. В тяжелых случаях это приведет к нагреву и возгоранию, а также к аварии.
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?
Частичная замена батарей свинцово-кислотных батарей не рекомендуется.
Are you a battery manufacturer, and do you produce the plates by yourself ?
Да, мы являемся профессиональным производителем аккумуляторов в провинции Гуандун, Китай, с 2003 года. Мы производим свинцовые пластины в собственной мастерской.
Does your battery develop a memory?
Свинцово-кислотные аккумуляторы не имеют памяти. Это означает, что вам не нужно глубоко разряжать или полностью разряжать батарею перед ее зарядкой. Для оптимального срока службы и производительности мы обычно рекомендуем разряд от 20 до 50% номинальной емкости батарей, даже если батарею можно перезарядить до 90%.
How does temperature affect the performance of my batteries?
При более высоких температурах (выше 77º F (25º C)) емкость батареи обычно увеличивается, обычно за счет срока службы батареи. Более высокие температуры также увеличивают характеристику саморазряда. Более низкие температуры (ниже 77º F (25º C)) снизят емкость аккумулятора и продлят срок его службы. Более низкие температуры замедляют саморазряд. Таким образом, эксплуатация батарей при температуре 77º F (25º C) или немного ниже оптимизирует как производительность, так и срок службы.
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?
Первичные батареи — это обычные сухие батареи, которые можно использовать только один раз. Вторичные батареи также называются перезаряжаемыми батареями, их можно заряжать и разряжать много раз. Наши батареи являются вторичными батареями.
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?
Эффективность разряда относится к отношению фактической мощности к номинальной емкости, когда аккумулятор разряжается при конечном напряжении в определенных условиях разряда. На него в основном влияют такие факторы, как скорость разряда, температура окружающей среды, внутреннее сопротивление. Как правило, чем выше скорость разряда, тем ниже эффективность разряда; чем ниже температура, тем ниже эффективность разряда.
What is the difference between float and cycle applications?
Плавающее приложение требует, чтобы батарея была постоянно заряжена с периодической разрядкой. Циклические приложения регулярно заряжают и разряжают аккумулятор.

А: Емкость батареи относится к количеству электричества, которое активный материал в батарее может участвовать в электрохимической реакции, называется емкостью батареи, то есть количеством заряда, который батарея может удерживать после зарядки. Единица измерения – «Ач» (Ач) и 1 А (А). Ток разряжается в течение 1 часа, а емкость составляет 1 ампер-час (Ач). Предполагая, что средний ток равен 4А, время разряда составляет 3 часа, когда батарея разряжена при предельном напряжении батареи, а емкость батареи составляет 12Ач (разряд здесь не рассчитывается) эффективность).
А: Это относится к сопротивлению току, протекающему через батарею, когда батарея работает. Есть две части: омическое внутреннее сопротивление и поляризационное внутреннее сопротивление. Большое внутреннее сопротивление батареи приведет к уменьшению рабочего напряжения разрядки батареи и сокращению времени разрядки. Внутреннее сопротивление в основном зависит от материала батареи, производственного процесса, структуры батареи и других факторов. Является важным параметром для измерения производительности батареи.
А: В процессе зарядки аккумулятора часть электрической энергии преобразуется в химическую энергию, а часть электрической энергии преобразуется в тепловую энергию и другую энергию. Аккумуляторная батарея нагревается нормально, но если температура слишком высокая, следует проверить, не слишком ли велик зарядный ток и не произошло ли короткое замыкание внутри батареи.
А: Аккумулятор может иметь небольшое количество тепла, независимо от того, используется ли он или во время зарядки, но чрезмерное нагревание не допускается. Аномальная лихорадка очевидна, и вы можете почувствовать ее, прикоснувшись к корпусу батареи рукой. Тепло очень вредно для батареи. Тепло сначала вызывает испарение и постепенное высыхание воды электролита, а затем снижает эффективность заряда, деформирует пластины, увеличивает внутреннее сопротивление, ускоряет окисление механических частей, выгорает пластины или сепараторы и, наконец, проявляется в снижении емкости аккумулятора и укороченная жизнь.
А: Плохое соединение приведет к увеличению сопротивления в месте соединения, что может легко вызвать искрение во время зарядки и разрядки. В тяжелых случаях это приведет к нагреву и возгоранию, а также к аварии.
А: Несмотря на то, что свинцово-кислотная батарея была строго отобрана, когда она покидает завод, после определенного периода использования неоднородность будет появляться и постепенно увеличиваться. Зарядное устройство не может распознать или дополнить недостаточный заряд. Как сбалансировать емкость аккумулятора? Его должны выполнять люди. Пользователь периодически и нерегулярно измеряет напряжение холостого хода каждой батареи в середине и конце периода использования батареи. Для более низкого напряжения заряжайте отдельно, чтобы напряжение и емкость соответствовали другим батареям, и постарайтесь уменьшить их разрыв.
А: Да, мы являемся профессиональным производителем аккумуляторов в провинции Гуандун, Китай, с 2003 года. Мы производим свинцовые пластины в собственной мастерской.
А: Свинцово-кислотные аккумуляторы не имеют памяти. Это означает, что вам не нужно глубоко разряжать или полностью разряжать батарею перед ее зарядкой. Для оптимального срока службы и производительности мы обычно рекомендуем разряд от 20 до 50% номинальной емкости батарей, даже если батарею можно перезарядить до 90%.
А: При более высоких температурах (выше 77º F (25º C)) емкость батареи обычно увеличивается, обычно за счет срока службы батареи. Более высокие температуры также увеличивают характеристику саморазряда. Более низкие температуры (ниже 77º F (25º C)) снизят емкость аккумулятора и продлят срок его службы. Более низкие температуры замедляют саморазряд. Таким образом, эксплуатация батарей при температуре 77º F (25º C) или немного ниже оптимизирует как производительность, так и срок службы.
А: Возможно, вы слышали, что «вам нужно трехступенчатое зарядное устройство». Мы говорили это, и мы скажем это снова. Лучшее зарядное устройство для аккумулятора — это трехступенчатое зарядное устройство. Их также называют «умными зарядными устройствами» или «зарядными устройствами, управляемыми микропроцессором». По сути, эти типы зарядных устройств безопасны, просты в использовании и не будут перезаряжать аккумулятор. Почти все зарядные устройства, которые мы продаем, являются трехступенчатыми зарядными устройствами. Итак, трудно отрицать, что трехступенчатые зарядные устройства работают и работают хорошо. Но вот вопрос на миллион долларов: каковы три этапа? Что делает эти зарядные устройства такими разными и эффективными? Это действительно того стоит? Давайте узнаем, пройдя каждый этап, один за другим:
Этап 1 | Массовая зарядка
Основное назначение зарядного устройства для аккумуляторов — перезарядка аккумулятора. На этом первом этапе, как правило, фактически используются самые высокие напряжение и сила тока, на которые рассчитано зарядное устройство. Уровень заряда, который может быть применен без перегрева батареи, известен как естественная скорость поглощения батареи. Для типичной 12-вольтовой AGM-батареи напряжение зарядки, поступающее в аккумулятор, достигает 14,6-14,8 вольт, а у залитых аккумуляторов может быть еще выше. Для гелевого аккумулятора напряжение должно быть не более 14,2-14,3 вольта. Если зарядное устройство представляет собой зарядное устройство на 10 ампер, и если сопротивление батареи позволяет это, зарядное устройство будет выдавать полные 10 ампер. На этом этапе аккумуляторы будут перезаряжаться, если они сильно разряжены. На этом этапе нет риска перезарядки, потому что батарея еще даже не полностью заряжена.
Этап 2 | Поглощающий заряд
Интеллектуальные зарядные устройства определяют напряжение и сопротивление аккумулятора перед зарядкой. После считывания заряда батареи зарядное устройство определяет, на каком этапе следует правильно заряжать. Как только аккумулятор достигнет уровня заряда 80%*, зарядное устройство перейдет в режим абсорбции. В этот момент большинство зарядных устройств будут поддерживать постоянное напряжение, в то время как сила тока снижается. Меньший ток, поступающий в аккумулятор, безопасно повышает заряд аккумулятора, не перегревая его.
Этот этап занимает больше времени. Например, последний оставшийся 20% батареи занимает гораздо больше времени по сравнению с первым 20% на этапе массовой загрузки. Ток непрерывно снижается, пока батарея почти не достигнет полной емкости.
* Фактическое состояние заряда, на которое перейдет стадия поглощения, зависит от зарядного устройства.
Этап 3 | Плавающий заряд
Некоторые зарядные устройства переходят в плавающий режим уже при состоянии заряда 85%, но другие начинают ближе к 95%. В любом случае, поплавковая ступень полностью заряжает аккумулятор и поддерживает состояние заряда 100%. Напряжение будет снижаться и поддерживаться на стабильном уровне 13,2-13,4 В, что является максимальное напряжение, которое может выдержать 12-вольтовая батарея. Ток также уменьшится до точки, где он считается струйкой. Отсюда и пошло выражение «капельное зарядное устройство». По сути, это плавающая стадия, когда заряд поступает в аккумулятор постоянно, но только с безопасной скоростью, чтобы обеспечить полный заряд и не более того. Большинство интеллектуальных зарядных устройств не отключаются в этот момент, однако совершенно безопасно оставлять аккумулятор в плавающем режиме на месяцы и даже годы.
Для батареи лучше всего иметь уровень заряда 100%.
Мы говорили это прежде, и мы скажем это снова. Лучшим зарядным устройством для аккумулятора является 3-ступенчатое интеллектуальное зарядное устройство. Они просты в использовании и не беспокоят. Вам никогда не придется беспокоиться о том, чтобы оставить зарядное устройство на аккумуляторе слишком долго. На самом деле, лучше оставить его включенным. Когда батарея не полностью заряжена, кристаллы сульфата накапливаются на пластинах, и это лишает вас энергии. Если вы оставляете свой PowerSports в сарае в межсезонье или на время отпуска, подключите аккумулятор к 3-ступенчатому зарядному устройству. Это гарантирует, что ваша батарея будет готова к запуску в любое время.
А: Чрезмерная разрядка — это проблема, возникающая из-за недостаточной емкости аккумуляторов, что приводит к их перегрузке. Более глубокие разряды, чем у 50% (на самом деле значительно ниже 12,0 В или удельного веса 1,200), значительно сокращают срок службы батареи без увеличения полезной глубины цикла. Нечастая или неадекватная подзарядка также может вызвать симптомы чрезмерной разрядки, называемые СУЛЬФАЦИЯ. Несмотря на то, что зарядное оборудование регулирует обратно правильно, симптомы чрезмерной разрядки проявляются в виде потери емкости аккумулятора и более низкого, чем обычно, удельного веса. Сульфат образуется, когда сера из электролита соединяется со свинцом на пластинах и образует сульфат свинца. Как только возникает это условие, морские зарядные устройства не удаляют затвердевший сульфат. Сульфат обычно можно удалить с помощью надлежащей десульфатации или выравнивающей зарядки с помощью внешних ручных зарядных устройств. Для выполнения этой задачи залитые пластинчатые аккумуляторы необходимо заряжать током от 6 до 10 ампер. от 2,4 до 2,5 вольт на элемент до тех пор, пока все элементы не начнут свободно выделять газ и их удельный вес не вернется к полной концентрации заряда. Герметичные батареи AGM следует довести до 2,35 вольта на элемент, а затем разрядить до 1,75 вольта на элемент, а затем этот процесс необходимо повторять до тех пор, пока емкость не вернется к батарее. Гелевые аккумуляторы могут не восстановиться. В большинстве случаев батарея может быть возвращена для завершения срока службы. ЗАРЯДКА Генераторы переменного тока и поплавковые зарядные устройства для аккумуляторов, включая регулируемые зарядные устройства для фотогальванических элементов, имеют автоматическое управление, которое снижает скорость зарядки по мере того, как аккумуляторы заряжаются. Следует отметить, что снижение до нескольких ампер при зарядке не означает, что аккумуляторы полностью заряжены. Зарядные устройства для аккумуляторов бывают трех типов. Существует ручной тип, тип струйки и тип автоматического переключателя.
А: Первичные батареи — это обычные сухие батареи, которые можно использовать только один раз. Вторичные батареи также называются перезаряжаемыми батареями, их можно заряжать и разряжать много раз. Наши батареи являются вторичными батареями.
А: Наиболее распространенным рейтингом батареи является РЕЙТИНГ AMP-HOUR. Это единица измерения емкости батареи, полученная путем умножения силы тока в амперах на время разрядки в часах. (Пример: батарея, выдающая 5 ампер в течение 20 часов, дает 5 ампер, умноженных на 20 часов, или 100 ампер-часов.)
Производители используют разные периоды разряда, чтобы получить разные ампер-часы. Номинал для аккумуляторов одинаковой емкости, следовательно, Ампер-час. Рейтинг не имеет большого значения, если только он не определяется количеством часов, в течение которых батарея разряжалась. По этой причине рейтинги в ампер-часах являются лишь общим методом оценки емкости батареи для целей выбора. Качество внутренних компонентов и техническая конструкция батареи будут генерировать различные желаемые характеристики, не влияя на ее номинальное значение в ампер-часах. Например, существуют аккумуляторы емкостью 150 ампер-часов, которые не будут поддерживать электрическую нагрузку в течение ночи и, если потребуется делать это повторно, выйдут из строя в самом начале своего срока службы. И наоборот, есть батареи емкостью 150 ампер-часов, которые будут работать от электрической нагрузки в течение нескольких дней, прежде чем потребуется подзарядка, и будут делать это в течение многих лет. Чтобы оценить и выбрать подходящую батарею для конкретного применения, необходимо изучить следующие характеристики: СИЛА ПРИ ХОЛОДНОМ ПРОВОДЕ и РЕЗЕРВНАЯ ЕМКОСТЬ — это характеристики, используемые в отрасли для упрощения выбора батареи.
А: Резервная емкость — это количество минут, в течение которых батарея может поддерживать полезное напряжение при разряде 25 ампер. Чем выше минутный рейтинг, тем выше способность батареи работать с освещением, насосами, инверторами и электроникой в течение более длительного периода времени, прежде чем потребуется подзарядка. 25 Ампер. Рейтинг резервной емкости более реалистичен, чем ампер-час или CCA, как измерение емкости для глубокого цикла обслуживания. Аккумуляторы, рекламируемые с высоким рейтингом холодного пуска, просты и недороги в изготовлении. Рынок наводнен ими, однако их резервная емкость, срок службы (количество разрядов и зарядов, которые может обеспечить батарея) и срок службы невелики. Резервную емкость сложно и дорого реализовать в аккумуляторе, и для этого требуются более качественные материалы для элементов.

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?
Быстрая зарядка не рекомендуется, так как это вредно для аккумулятора.
What are the reasons for the battery warming up during charging?
В процессе зарядки аккумулятора часть электрической энергии преобразуется в химическую энергию, а часть электрической энергии преобразуется в тепловую энергию и другую энергию. Аккумуляторная батарея нагревается нормально, но если температура слишком высокая, следует проверить, не слишком ли велик зарядный ток и не произошло ли короткое замыкание внутри батареи.
What is the battery's charge acceptance?
При заданных условиях зарядного напряжения и тока количество заряда, которое батарея принимает в единицу времени.
What is the harm of the battery heating?
Аккумулятор может иметь небольшое количество тепла, независимо от того, используется ли он или во время зарядки, но чрезмерное нагревание не допускается. Аномальная лихорадка очевидна, и вы можете почувствовать ее, прикоснувшись к корпусу батареи рукой. Тепло очень вредно для батареи. Тепло сначала вызывает испарение и постепенное высыхание воды электролита, а затем снижает эффективность заряда, деформирует пластины, увеличивает внутреннее сопротивление, ускоряет окисление механических частей, выгорает пластины или сепараторы и, наконец, проявляется в снижении емкости аккумулятора и укороченная жизнь.
What is the danger if the connecting bolts are not tightened?
Плохое соединение приведет к увеличению сопротивления в месте соединения, что может легко вызвать искрение во время зарядки и разрядки. В тяжелых случаях это приведет к нагреву и возгоранию, а также к аварии.
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?
Частичная замена батарей свинцово-кислотных батарей не рекомендуется.
Are you a battery manufacturer, and do you produce the plates by yourself ?
Да, мы являемся профессиональным производителем аккумуляторов в провинции Гуандун, Китай, с 2003 года. Мы производим свинцовые пластины в собственной мастерской.
Does your battery develop a memory?
Свинцово-кислотные аккумуляторы не имеют памяти. Это означает, что вам не нужно глубоко разряжать или полностью разряжать батарею перед ее зарядкой. Для оптимального срока службы и производительности мы обычно рекомендуем разряд от 20 до 50% номинальной емкости батарей, даже если батарею можно перезарядить до 90%.
How does temperature affect the performance of my batteries?
При более высоких температурах (выше 77º F (25º C)) емкость батареи обычно увеличивается, обычно за счет срока службы батареи. Более высокие температуры также увеличивают характеристику саморазряда. Более низкие температуры (ниже 77º F (25º C)) снизят емкость аккумулятора и продлят срок его службы. Более низкие температуры замедляют саморазряд. Таким образом, эксплуатация батарей при температуре 77º F (25º C) или немного ниже оптимизирует как производительность, так и срок службы.
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?
Первичные батареи — это обычные сухие батареи, которые можно использовать только один раз. Вторичные батареи также называются перезаряжаемыми батареями, их можно заряжать и разряжать много раз. Наши батареи являются вторичными батареями.
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?
Эффективность разряда относится к отношению фактической мощности к номинальной емкости, когда аккумулятор разряжается при конечном напряжении в определенных условиях разряда. На него в основном влияют такие факторы, как скорость разряда, температура окружающей среды, внутреннее сопротивление. Как правило, чем выше скорость разряда, тем ниже эффективность разряда; чем ниже температура, тем ниже эффективность разряда.
