How much voltage and current to charge a 24V battery?
Then to charge two batteries in series, apply a maximum voltage of 27.6V and a maximum current of 18A. Remember, you can always make this safer by lowering the max current. I advise starting at 1/4C or lower and only increase to 1C if you really want fast charge and are well prepared to handle the potential heat and gas production.
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., the capacity is 45 Ah.
