How to charge a battery. An average car battery has a capacity of around 48 amp hours which means that, fully charged, it delivers 1 amp for 48 hours, 2 amps for 24 hours, 8 amps for 6 hours and so on. basic charger usually charges at around 2 amps-and so needs 24 hours to deliver the 48 amps needed to fully charge a flat, 48 amp hour battery. But there is a wide range of chargers with different charge rates on the market-from 2 to 10 amps. The higher the charge output, the faster a flat battery is recharged.
Therefore it is necessary to put about 30 amp hours plus 20% more to compensate for the internal resistance in the battery for a total of 30 amps x 0.2 = 36 amp-hours to fully charge your battery. Step 3: If you charge your battery at a 10-amp rate and you need to replace 36 amp-hours in the battery. To determine how long (in hours) you will need to charge your battery, divided 36 by 10 = 3.6 or 3.6 hours to recharge your battery. A 12 volt / 10 amp 3-stage automatic charger is the best charger for most automotive batteries.
