Now that the seasons are changing, it is a good time to perform some maintenance on your car battery.
Since the battery delivers power to your car through heavy cables, it is wise to check the battery cables and make sure they are tightened properly. Use a pair of channel locks to tighten.
Cleaning the terminals and clamps is the next step. Clean the posts and clamps with a wire brush until they shine.
Check the fluid level and refill with distilled water when necessary. Use a funnel to fill the fluid level to approximately ¼” below the bottom of the filler hole. Some cars have a “maintenance free battery” so this step can be omitted.
Always wear safety glasses when working near car batteries. Car batteries contain sulfuric acid, which can burn your skin. If you get the acid on yourself, immediately flush the area with water.
