Whether you have a brand new BMW or a used model, you might wonder how often to replace your car battery to ensure the best performance around Corona. On average, a BMW battery will last three to five years. However, there are many factors that influence the lifespan of your equipment. Take a look at how to know if your car battery needs to be replaced with the service department at BMW of Murrieta!


Why Do I Need a BMW Battery Replacement?

Every BMW battery has a shelf life, and certain factors can cause the battery components to deteriorate even faster:

  • Heat: The heat of Riverside summers can evaporate the liquids inside the car battery, which can reduce the lifespan of your battery.
  • Vibrations: Your battery is secured with hold-down clamps, but those clamps can loosen. When your battery is jostled over rough roads, the vibrations can cause extra stress on your equipment.
  • Jump Starts: When your battery drains enough to need a jump start, this can shorten your battery lifespan significantly.
  • Quality: On average, we’ve found that OEM parts tend to last much longer than aftermarket alternatives.
  • Time: Eventually every BMW driver needs a BMW battery replacement, so be sure to get regular battery inspections as part of your maintenance visit.

How to Know if Your Car Battery Needs to be Replaced?

You know how often to replace a car battery, but what are the signs that your battery is on its last legs?

  • Dimming headlights
  • More frequent need for engine revving or jump starts
  • Takes longer to start the engine when you turn the key/push the button
  • Unusual power fluctuations

While you can schedule your service for a battery check, you can also learn how to test a car battery in your own Ontario garage. Where is the battery in a BMW? It’s often found in the trunk, beneath the liner, rather than under the hood.

You can pick up a digital multimeter at our parts department and test the battery levels precisely, or you can use a simple headlight test. Turn on your car, flip on the headlights, and rev the engine. If your headlights get brighter, your battery might be fading.

How Much is a Replacement Car Battery?

All BMW OEM parts have a two-year limited warranty with unlimited mileage, but if your battery is older, you’ll need a replacement. What is the cost to replace a battery? BMW battery replacements typically cost between $300 and $500 with parts and labor.
