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.f there is a power point handy, the battery can be left in the car, so long as the charge rate is only 3 or 4 amps. However, if the car has an alternator, disconnect the battery. beforehand: otherwise some alternators-generally the older type-can be damaged. If separate. caps are fitted, remove them for ventilation.
A: Charging time depends on the battery and the charger. For a battery being charged by the car's alternator it can take an hour of driving to get it fully charged. Car batteries range from 40AH to 110AH, and alternators range from 45 amps to 200 amps. If you are using a battery charger, a 10 amp charger will take 4 to 11 hours to fully charge the battery, a 2 amp charger will take 2-4 days. Of course you don't have to get the battery to full charge to get it to start the car.
