How long do car batteries last?

When it comes talking about cars or anything automotive, it’s easy to get seduced by the concept of performance. It’s very linear and easier to understand – the more horsepower an engine produces, the faster it will go. However, an engine isn’t much more than a very intricate paperweight with a properly working battery. These days batteries don’t require much attention until they do. So, how do car batteries last? Most of the automotive experts working in the Gwatney Mazda of Germantown Service Department say the average is about four years. Let’s see if we can help you find ways to make it last longer.

If you’ve even taken the shortest of peeks under the hood, it doesn’t take much to understand that there are a lot more electronics and computer controls in place than in previous generations of vehicles. Naturally, this is going to require a well-charged battery with enough power to start the vehicle and run all of its systems.

Once a vehicle is running, the responsibility for powering all of the electronics falls to the alternator. It basically acts as a generator that recharges the battery while you’re driving. Among the things that will shorten the lifespan of the battery is frequent short drives. It always takes a big jolt of power to get it started, if the alternator doesn’t have sufficient time to do its job, the battery will suffer.

The other most common reason a battery might die before its time is overuse. Leaving your headlights, interior lights or accessories turned on, will drain the battery very quickly. Most people learn their lesson after needing to call for a jump start. However, repeatedly needing to get the battery jumped is not only bad for it but also could be a sign it’s time for a new one.
