What Causes Car Battery Deterioration?
There are several factors that contribute the deterioration of your car’s battery, but here are some of the most common factors:- Heat: Hot weather causes the evaporation of liquids inside a car battery, so if you drive in a hotter climate, your car battery’s lifespan may be shorter.
- Vibrations: If your battery’s hold-down clamps are loose, or you drive over rough Anderson roads frequently, vibrations will cause internal battery parts to break down faster.
- Needing a Jump: If you’ve left your lights on overnight or let your engine idle for too long and you require ajump start, this can shorten battery life significantly.

- Turn on the engine, keep the car in park, and make sure the headlights are on.
- Rev the engine and see if the headlight brightness changes.

- Take your car to a service center at this point for further assessment.
