HI all. Put a new battery in my car about a month ago. All is fine, been driving car regularly. Its been a few days that the car has been parked so I go to start it today and no power. I put the charger on the car to see if I could get power, I do, it starts charging. I went out not too long ago and now I figured out what happened. The vanity mirror bulb for the visor was on ( apparently these wear out and eventually you have to fasten it just right or the bulb will stay on) My question, is my battery toast? Or should it be fine if I leave it on the charger overnight?
