Car battery 12 volt how many amps How many amps in 12 volt

1, car battery 12 volts: 40 amps (ah) to 100 amps (ah).

2, small cars are generally 12V40A -----12V60A ranging from freight cars generally 24V.

3, you can see from the top of the battery, there is a maximum ampere hours.

4, 12v battery working current depends on its model, that is, capacity, generally marked on the shell, the greater the working current when the time is shorter, for example, 20Ah battery to 2Amps current discharge, can last 10 hours, you need to charge.

5, the instantaneous maximum current can be 70 to 100 amps, or even higher. But pay attention to ultra-high will be prone to problems, and even battery explosion.

6, when the battery serious power loss, relying solely on the car generator charging is not possible, you should use a portable charger to charge.
