Why Should I Change my Battery?

Car batteries wear out over time, and extremely hot or cold weather can speed up a good battery’s demise. The cold is commonly thought of as a killer of batteries, but that's because the it takes more exertion. Typically these batteries lose strength before the winter, and then finally fail when trying to start up the engine in the cold.

How to Identify a Faulty Battery

There are several ways that you can figure out how to identify a faulty battery. Check its age. The bottom line is that older batteries have many more issues than younger batteries and are more likely to fail. If your battery has been in your car for several years, it's probably best to make the assumption that it needs to be changed. Batteries wear down over time due to things like multiple cycles of discharging. They can also break down over time if they’re constantly exposed to extreme temperatures or temperature changes.

How Long Does an Auto Battery Last?

Most people ask, How long does an auto battery last? because they want to be prepared ahead of time. In general, car batteries last anywhere from three to five years. There are several factors that will determine how long your battery will last.

If you drive in extreme temperatures, the exposure to those temps will have a huge impact on the life of the battery. If you're constantly on the road taking the car for long trips, that's another thing that could affect your battery's lifespan. If your alternator and drive belt are starting to break down, those are additional issues that could shorten your battery’s life span.

You may have reached the five-year point with no issues. This is because many of the latest batteries are designed to work right up until the point that they fail. This means that you're unlikely to get a lot of warning signs before the battery dies. This could be particularly bad if you’re nowhere near help.
