Does starting a car keep the battery charged?
“Starting the engine draws 100 to 130 amps, and idling the car for 15 minutes might put back three or four amps,” Brown-Harrison says. “If you’re idling only for 15 to 20 minutes, the battery never truly gets recharged. So each time you start and leave it to idle, the charge will get lower and lower and lower.”
Can a car battery be charged when not in use?
When your car battery is hooked up to your car when it’s not in use, then it will lose a charge faster because there are various systems in a car that will need electricity to function even when the car isn’t on.

Why does my car battery keep going bad?
If you start the car and then only drive it about five miles or less, then you are not recharging the battery sufficiently. Such repeated draining of the battery will cause it to go bad pretty quick. I suggest using a battery charge tender to keep the battery charged between uses.
