It depends on the year and model of your BMW 5 series. For most BMW 5 series models, you do not need to reprogram the computer when replacing the battery. However, for some newer models, such as the 2019 BMW 5 series, it is recommended to have the battery registered with the car's computer system using a BMW diagnostic tool. This process ensures that the car's charging system is properly calibrated to the new battery. If you are unsure whether or not your BMW 5 series requires battery registration, it is best to consult with a BMW dealership or a qualified mechanic.
