A car battery is permanently dead when it can no longer hold a charge. If the alternator in your vehicle cannot charge up the battery, it is time to replace it. There are tons of different things that can affect the total life of your battery. When you take the time to learn about some of these things, you will have an easier time maintaining your vehicle.

Average Battery Life

Car batteries typically last anywhere from two to five years. If your battery is over two years old, you should get it tested at least once each year. This can help you determine whether or not you should start thinking about replacing it. Any mechanic will be able to do this for you very easily. It could save you from getting stranded on the side of the road.

Shopping for the Right Battery

The overall quality of the battery itself plays a big role in roughly how long it is going to last. There are a number of things that you should pay attention to before buying any battery in particular.

Size of the Battery

You will need to make sure that you buy the right size battery for your vehicle. If you unsure of which one to get, you can always refer to the owner?s manual. This information will help you avoid buying the wrong battery, which can be very frustrating. If you put the wrong size battery in your car, it could cause all sorts of serious problems.

New vs. Used

Some people decide to buy used/recycled batteries because they tend to be much cheaper. These batteries cost about half of a new one, but it doesn?t mean they are worth your money. It is pretty much a crapshoot in the sense that the battery could last a few months or a few years. This is a pretty big chance to take, so you?ll want to think twice about it.


The manufacturer of the car battery can indicate whether or not it is a quality product. There are some companies that have a better reputation than others in this industry. Some of the top names when it comes to these batteries include NAPA, Kirkland, Optima, and Odyssey. You definitely want to take this into consideration before buying anything.
