Changing Vehicle Battery in Todays High Tech BMWs

You might think replacing a battery in a late model BMW is a simple matter. Just swing by the local tire store and swap it out, right?

In reality you may get some life from even the best battery this way but still not get your money’s worth.

When replacing a battery with anything but the exact same size and rated battery the vehicle must be reprogrammed.

For instance if the vehicle is only driven on short trips or not driven often, the white wet, acid and led plate batteries can tend to fail. Because of the high electrical demands placed on these vehicles upgrading to the Black Absorbent Glass Mat (AGM) batteries may be desirable. While some after market systems allow programming individual modules the BMW GT-1 and SSS system does not. After programming, the new battery must then be electronically “registered.”

By the way the technician can look in your network and determine how often and how far your vehicle has been driven as well as if the battery in the car has been “registered” or not.

Not reprogramming the car to relearn the condition of the battery will result in shortened battery life.
