It is dead when the car doesnt start. You can see warning sighs when your car takes longer to start, or when rolling your windows up or down takes longer than normal.

In some cases a battery with a dead cell will not even accept a charge.

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.


Does driving the car also charge the battery if its dead?

Yes, once you have jump started the car (from another car's battery), driving the car will recharge the dead battery (provided the battery is OK). This is a terrible idea and may damage the alternator. Drive the car immediately home and charge the battery with a battery charger. Alternators are designed to keep a charged battery fully charged. They are not designed to charge a dead battery. This puts way too much strain on the alternator circuits.
