How many times can you start a car before the battery dies?
The easiest thing you can do to prevent your car battery from dying is to start your car once a week and letting it run anywhere from 5 to 10 minutes.

Does revving the engine charge the battery?
The battery will charge faster if you rev the engine faster. Why? Because the faster the crankshaft turns, the faster it turns the belt that runs the alternator. And the faster the alternator turns, the more electricity it produces to run all the electrical stuff in the car — and recharge the battery.
What drains a car battery while it is off?
What may drain a car battery when it’s off are things such as interior lights, door lights, or even bad relays.
