Q: Battery not staying charged

asked by on

Battery keeps going dead

My car has 297000 miles.
My car has an automatic transmission.

Hi, thanks for writing in. This is likely a charging system problem or potentially a bad grounding connection. Check to be sure your battery cables are clean and free of corrosion and that the black (ground) cable is properly connected to the chassis of the vehicle which ensures a proper ground. If the connections check out fine, then you likely have a charging problem which is usually related to a faulty alternator or voltage regulator. If you would like help, consider having an expert automotive technician from YourMechanic come to your home or office to inspect and diagnose this issue for you, and make or suggest any repairs as needed.
