asked by on

My mazdas battery died and when i get into the vehicle, it sounds like something in the car is on. I do not know if it is suppose to be like that, or if something is on and i don't know it. could this lead to the car dying?

My car has 109000 miles.
My car has an automatic transmission.

Late model cars use a lot of power while the key is off. We call that "parasitic drain." In normal cases it doesn’t exceed 200 milliamps and at that rate the battery should stay alive. Like your computer, your car goes through a shut down procedure that takes about 20 minutes and sometimes when something goes wrong, not everything shuts down as it should. This can drain a battery overnight. Figuring out what is not shutting down can be challenging and requires a pretty thorough knowledge of your cars systems. To have it checked out at your convenience, contact YourMechanic. They can send a technician to your home or office to check out your electrical system and let you know what it will take to solve your problem.
