AC, Car Battery and More - Maintain your car's battery
Maybe the manufacturer says your battery is maintenancefree, but don't you believe it! Check your battery regularly to extend its life and avoid the hassle of being stranded with a dead battery.
- Begin with the simple: keeping your battery clean. A dirty case can actually cause current to drain. Wipe with a damp rag. Use a mild detergent if necessary.
- Next, clean the battery posts or terminals. Loosen and remove the negative cable (black or minus sign) first, then the red positive cable. Use a brass wire battery brush dipped in a paste made from a few tablespoons of baking soda and a little water.
- Inspect the battery case for damage, such as cracks or bulges - signs that a battery needs to be replaced.
- Reinstall the cables, positive first, and coat the terminals and clamps with a thin coating of grease to prevent new corrosion.
