4. What sort of maintenance should I perform on my battery?

Modern automotive and light truck batteries need little attention. Check the battery once a year for signs of corrosion at the terminals. Clean the terminals with a mixture of baking soda and water. Keep the top of the battery clean of heavy dirt and oil to prevent low grade short-circuiting.

Some batteries are equipped with removable vents so the electrolyte levels in each cell can be checked and filled with water if the level is low. Always use good quality drinking water or distilled water to prevent iron or other chemicals from contaminating the electrolyte. Be careful not to overfill the cells or acid may be expelled during operation or charging. If your vehicle has not been started in more than a month, recharge the battery before using the car.
