Our online calculator will help to calculate how much time needs for charging a car battery, using a direct current.
Therefore, it is always suggested to charge 12 volts battery at 10 amps. So when you are charging a battery at 2 amps then it takes 24 hours for the battery to receive 48 amps of charge. If you have a 100 amp battery, then the battery will take 5 hours to reach the 50% battery capacity.
However, it may take longer if your charger isn't compatible with the battery or if there's some underlying defect with the battery itself. So by the time it’s at say 90% charged, it may only accept about 5 or 6 amps. In those instances, it could take up to 5 hours.
