How long should a car battery last?

If you are having trouble starting your car, or if you find that the battery is no longer maintaining its charge, or if your car is dead after a few days of standing, it is probably time to change your battery.

Car batteries have a lifespan, just like any other kind of battery. As fitted by manufacturers to new cars, batteries have been known to last for up to 7 years, but in older cars, batteries will usually only last an average of 2 to 3 years.

You can replace a car’s battery yourself, but you will need to give in your old battery when purchasing a new one. However, seeing as most fitment centres don’t charge to change out the batteries or perform a battery check, it is easier just to have them do it for you.

Car batteries are not all created equal, though, and you will need to make sure you get the right size, shape and amperage for your car. Also note that the battery terminal locations and polarity may vary, depending on the different designs out there.
