Clean Your Battery

The best way to keep your battery running smoothly is to keep it clean. Regularly detach the battery cables and wipe off the terminals. Make sure the battery is strapped down tightly and that all connections are secure.

If you suspect that your battery is being overcharged or isn't holding a charge well, take it to a service shop where they can run a quick battery inspection. And if you need to replace the battery, make sure that it's the right battery type for your specific make and model of car.
