Like all parts, batteries run their course. Most will last up to five years, depending on conditions and how often you drive. Signs of an aging battery include an audible slow crank when you attempt to start your engine, a lit check engine/battery light or the strange odor of rotten eggs.

Several factors can affect a car battery's lifespan. The most common factors are faulty charging systems, dirt, rust build-up, and hot temperatures. Car batteries fail to last as long in hot climates because they're more chemically active in higher temperatures. This heat increases the risk of damage to the battery's internal structure. 

A malfunctioning charging system can also reduce your battery's lifespan. Usually, a faulty alternator will keep the battery charging circuit running even when the car engine is shut or fail to produce ample voltage.

Car battery failure can also be something as simple as grease, dirt, and rust building up so that the battery circuits become less efficient. As the current flow is restricted, the battery must work harder and won't last as long. You can prevent each of these issues by having your battery regularly inspected and replaced when needed.
