Procedure

If you have already paired your Carly, skip pairing steps. We assume that the battery has already been replaced, and now we just need to complete the registration procedure.

  1. Plugin Carly for BMW into the OBD2 port under the dashboard (driver's side). Press the power button on your Carly if it has one. The red LED light will turn on. how to register new bmw battery with carly
  2. Turn ignition to ON position. Don't start the car. You can't register a new battery if the engine is running.
  3. Download Carly for BMW Pro.  The free version of Carly does not allow you to perform battery registration. You can use the free version of Carly for BMW to see how Carly Battery Registration works but you can't complete the registration. Use the free version to check if battery registration is possible for your BMW model and year.
  4. Besides the Carly for BMW Pro, you will need to purchase the Battery Registration add-on which is another $10. Total cost for the Carly Adapter, Carly Pro and in-app battery registration place this setup in the mid $100-$200 range.
