Best Answer

Car is off, meaning, the engine is turned off.

If it's not a hybrid, then it can in two ways

1 From another car... hook up the lines + and -

2 From a charging station, usually they plug in a wall socket, 110v/220v to 12v, and in a couple of hours, PRESTO, your battery is charged.

Charge a car without a battery?

You can start a car without a battery if you hook up a jump pack or use jumper camples but it could fry your alternator. It is pointless to charge a car without a battery. When you charge the car you are charging the battery.


New car battery not used for months will not accept charge from charger?

Some car battery charges will not charge a completely dead battery. You need to find a type of battery charger that is designed to charge a completely dead battery. You can get around this by hooking a car with a working battery up to the dead battery with jumper cables. The alternator/charging system of the car with the good battery will charge the dead battery. Leave them connected for about 30 min, then disconnect and try to use the battery charger again. If it still won't charge, hook it up to the car with the good battery for a longer period of time.
