How often do BMW batteries need replacement? 

As a BMW owner, you may already know that your car's battery is a critical component that requires periodic replacement. It provides the power needed to start your vehicle and run the electrical components. On average, a BMW battery will last three to five years. However, there are many factors that influence the lifespan of your equipment.  Regular maintenance, such as checking the battery terminals for corrosion and keeping the connections tight, can help extend the life of your battery.


How do I know when my batteries going out?

Some key signs that you have a bad battery are:

  • The car is difficult to start.

  • Once started, the car doesn't hold a charge for very long.

  • Dim or flickering taillights and headlights and/or dim interior and dashboard lights.

BMW Battery Registration: Why it is important and how TMJ Bimmers can help

Did you know that replacing the battery on a BMW requires more than just a simple battery swap? It requires a process called battery registration, which is essential for ensuring optimal performance and longevity of your car's electrical system.

What is BMW Battery Registration?

BMW battery registration is a procedure that needs to be performed after replacing the battery on your BMW. It involves resetting and updating the car's electronic system to recognize the new battery's specifications and to calibrate the charging and discharging functions accordingly. This process is important because modern BMWs are highly sophisticated vehicles with complex electronic systems that rely on the battery to function correctly.

Why is BMW Battery Registration important?

Failing to perform battery registration can lead to several issues, such as:

  1. Reduced battery life: When you replace your BMW's battery without registering it, the car's electronic system may not be calibrated correctly, which can cause overcharging or undercharging of the battery. Over time, this can reduce the battery's lifespan and performance.

  2. Malfunctioning electrical components: Modern BMWs have many electrical components that rely on the battery to function correctly. If the battery is not registered, these components may not receive the correct voltage, which can cause them to malfunction or fail.

  3. Reduced resale value: When you try to sell your BMW, potential buyers will expect that the car has been maintained correctly. Failing to perform battery registration can indicate to a potential buyer that the car has not been properly maintained, which can reduce its resale value.
