What amount of current should I use to charge a 12V car battery?

A 12V power regulated supply will hardly charge a 12V lead-acid battery at all because it doesn''t put out enough voltage. An unregulated supply will continue to charge the battery at gradually reducing current until it reaches its unloaded peak voltage, which could be 40% higher than its rating and is dependent on the mains voltage.

AGM Battery Voltage Chart

When your AGM battery is fully charged, it should show around 12.8 to 13.0 volts. Consider this the gold standard. But as your battery discharges, the voltage drops gradually.

How to Calculate the Battery Charging Current & Time?

First of all, we will calculate charging current for 120 Ah battery. As we know that charging current should be 10% of the Ah rating of battery. Therefore, Charging current for 120Ah Battery = 120 Ah x (10 ÷ 100) = 12 Amperes. But due to some losses, we may take 12-14 Amperes for batteries charging purpose instead of 12 Amps. Related Posts.
