A completely dead battery or a bad connection to the battery.
Use a battery charger.
Sounds like a dead battery. You need the battery to start the car, but once it is running the engine runs completely off of the alternator (which also recharges the battery if the battery is still good).
It wouldnt work
Replace the battery?
Start with checking/testing condition of battery and battery connections.
check the battery, its probably dead
Dead cell in the battery or corroded or loose battery cables.
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.
Yes. If the alternator is dead and you drive the vehicle, all the power is coming from the battery and it will eventually drain completely. Also, if a diode is shorted inside the alternator, that can drain a battery.
You can run a deep cycle battery completely dead without damaging the battery. They are designed to be run down.
Something is on drawing power from the battery or the battery has a dead cell and needs replacing.
