Why is BMW Battery Registration important?

In late model BMWs, the electrical system is so sophisticated that it tailors charging to both the type and age of the battery. When you replace the battery the BMW power management system will need to know if it's a new or used battery, lead acid or AGM (Advanced Glass Mat) battery, and the age of the battery itself. The computer needs to know this information because it charges the AGM differently than the traditional battery. The process of updating is called Battery Registration. Replacing the battery in these cars without registering it could result in potential electrical problems, overcharging or undercharging the battery. Worst case scenario, damage or destruction to your battery and/or electrical system. The charging system often shortens the life of an unregistered battery by charging too aggressively and this can sometimes damage other control units. In the Battery Registration process, the battery capacity is set to 80%, the current odometer reading and battery statistics are stored, and the stored temperature statistics are deleted. Don’t risk it, always have a new battery registered after installation. It will ensure a properly operating electrical system and save you time and money in the future.
