What charging current should I use for a lead acid battery?
Customers often ask us about the ideal charging current for recharging our AGM sealed lead acid batteries. We have the answer: 25% of the battery capacity. The battery capacity is indicated by Ah (Ampere Hour). For example: In a 12V 45Ah Sealed Lead Acid Battery, the capacity is 45 Ah. So, the charging current shouldRead More

Get PriceBattery Capacity
If the battery is being discharged very quickly (i.e., the discharge current is high), then the amount of energy that can be extracted from the battery is reduced and the battery capacity is lower. This is due to the fact the necessary components for the reaction to occur do not necessarily have enough time to either move to their necessary positions.
