When to Change Your Car's Battery. There are several signs that indicate the battery in your car is failing and needs to be replaced. Sluggish engine cranking and unusual electrical problems like flickering headlights are telltale signs of trouble, though they may also indicate problems with your car's alternator. You should also replace your battery if it is bulging or has a rotten egg smell.
Heat can also decrease a battery's lifespan significantly. Hot weather causes liquids inside batteries to evaporate as well as internal damage. This can occur whether you are driving or if the car is parked. The magazine recommends that vehicle owners in hotter parts of the country have their car battery tested after two years of ownership and then every year after. Those who live in colder areas can wait four years after buying a car to test performance and capacity, then every year after.
