My car's battery overheats when the key is on.
This is a safety hazard and should be addressed by a certified mechanic. Battery’s hold down brackets often become loose and can get caught between the battery’s posts causing a short. This can mean a wiring problem that can involve an electrical component with an internal short. Have a mechanic, like the ones at YourMechanic, come by and take a look.
