Usually it means that the alternator isn't charging the battery. Batteries store electricity and the alternator uses energy from the engine to produce electrical energy for all of the devices in the vehicle and to recharge the battery. If the alternator isn't working the battery will eventually loose it's charge and you will not be able to start the vehicle.

Very confusing question. I assume you mean what light comes on when the batteries is defective. If that is the case then the red battery warning or charging system warning light may come on. And then again the light may not come on at all. The light is there to warn you about a problem with the charging system and not necessarily with the battery.

The battery light means your battery is low. You should go to a mechanics.

It means there is a problem with the charging system. Normally a bad alternator.

It comes on when there is a problem with the charging system. Most of the time it means the alternator has failed.
