What Does Your Car Battery Do?

This mind sound like a silly question. But your car battery does things that most people might not ever think about. Obviously your car battery supplies the necessary electricity to start your car. But most people might not realize what all of this involves. Not only does your battery send electricity into the vehicle ignition system so that the engine’s spark plugs spark and ignite the fuel in the cylinder. But it also must turn the vehicle’s starter and alternator to turn over the engine and get electricity to keep the vehicle running.

The starter is the most difficult thing for the battery to move, because it turns the entire engine. It has to turn the engine over fast enough to get fuel injected into the cylinder, and for the cylinders to build up enough compression for the engine to run.

How Long Does A Car Battery Last?

On average, a car battery lasts between 2 and 5 years. If you live in the northern part of the United States, your vehicle battery normally lasts longer, because of the cold climate. The warmer the area is that you live in usually the shorter time your batter lifespan is. In the California bay area we fit right into the 2 to 5 year average depending on the battery quality.

Electrical Problems That Mimic A Dead Battery

Now this will be an interesting topic to write about. We get a lot of business from our customers who either diagnosed their car themselves, but replacing the battery did not solve their problem. Of they took it to another auto repair shop and they thought it was a battery problem but it wasn’t. Not to toot our own horn but we have been specializing in automobile electrical repairs for over 35 years and we really do know our stuff!

The most common thing that people mistake for a dead battery is a failed alternator. Their battery just won’t keep a charge even when you drive it around. People think it is the battery but the alternator just is not charging the battery up. Another less common culprit is some sort of a more serious electrical problem that continually drains energy from the battery. You get a similar affect to a failed alternator. The battery keeps losing its charge. But with an electrical drain and a good alternator the battery gets low when the car is not running rather than when it is running.
