Check your vehicle owner's manual for the your car battery’s location. Space under the hood is at a premium in many newer vehicles. Some batteries may be located in the trunk, under the floorboard or even tucked away out of sight behind a wheel well.
The most common cause of degraded battery performance in lead-acid batteries is sulfation, which occurs when sulfur collects on the lead plates in the battery, blocking the electric current. It’s not difficult to recondition a car battery at home.
