Replace the battery every three to four years.
While batteries can last more than five years in ideal driving conditions, factors such as temperature, the car’s age and nature of usage can impact the life of a battery. Many motorists are unaware that under the stress of normal city driving, the average life of a vehicle battery is about three years.
According to the National Car Care Council, drivers with batteries more than three years old should consider replacing them, since batteries rarely give warning signs that they are about to fail.
