Ampere-hours, or amp-hours for short. It's a measure of the total energy that can be stored in the battery. A battery rated for 20 Ah can supply 2A for 10 hours, or 5A for 4 hours, or 20A for 1 hour.

V is the batteries rated voltage. Ah is the amp-hour of the battery. This is a rating of how many amps it can supply for a given period of time. For example a 600 Ah battery with a 100 A load means that the battery should last 6 hours.


How long to charge dead laptop battery?

Check and see how many Ah (Amper hours) your battery is. If it is for a gas/gasoline car, then it is probably around 42 Ah; batteries for diesel are usually around 72 Ah. Check the power of your battery charger. It should be something between 4-6 A. You must divide the battery capacity by the charger strength to get the time necessary. For example: your battery is 42 Ah and your charger is 6 A. Then the time needed will be 42 Ah / 6 A = 7 h. Charge your battery no longer than 7 h. Please note that overcharging the battery permanently damages it.
