During BMW battery registration process the following happens.

Battery capacity is set to 80%
Current Odometer reading is stored
Delete stored battery statistics such as:
battery charge level.
Stored temperature statistics are deleted
During the battery registration process old battery charging history gets deleted. Now your BMW DME module knows the battery is new and doesn’t require as aggressive chargings as the old battery. This step should be performed every time the battery gets replaced.

If you change the battery rating and type you will need to perform coding as well to let your BMW (IBS / Power Module) know how to handle the new battery.

What model BMW’s need to have their batteries reprogrammed or registered?

2002 and newer 7-Series E65/E66 chassis
2003 and newer 6-Series E54/E63 chassis
2004 and newer 5-Series E60/E61 chassis
2005 and newer X5 E53 chassis with N62 engine
2006 and newer 3-Series E90/E91/E92/E93 chassis
2007 and newer X5 E70 chassis
2008 and newer X6 E71 chassis

What you need:

Foxwell NT510 Multi-system scanner


Step 1: Replace BMW Battery

Better stick with an AGM (Advanced Glass Mat) battery instead of switching to lead acid batteries if the stock was AGM battery.

Step 2: Register a new battery

Locate the on board diagnostic (OBD – 2) port under the dashboard near your brake pedal. Plug your BMW Foxwell NT510 scan tool into this port.

Turn the key to option II but don’t not start engine. If you have a Push Start button press it a couple of times. Don’t press the brake pedal when you press the start button. All the dashboard lights should turn on.

Register the new BMW battery with NT510:

1.Plug your Foxwell NT510 BMW scanner into the OBD2 port under the dashboard.

2.Turn ignition on, the key to position II. Do not start your car.

3. Select BMW. Scan for VIN. It will automatically look up the VIN number. Once VIN is found press OK.

4. Scroll down to the Body menu 4.

5. Scroll down to Power Supply (Battery) and press Enter.

6. Select option 2 for Battery registration.

In the next screen, you can perform the following.

Register new battery. Battery replacement is the same as the original.
Change battery capacity to higher or lower.
Change battery type between AGM and lead acid battery.

Do not unplug the scanner during the battery registration process
Do not turn off the ignition during the battery programming.
You don’t need to run option 2 and 3 if your replacement battery has the same specs as the old battery. Just new battery registration is all you need to complete.

You can also perform BMW maintenance functions such as registering a new battery, read and clear adaptations, activate and test all of the modules individually, engage the transmission, among many others.

2008 BMW E93
Register a new battery -OK

2009 BMW 335i (American)
Do battery registration – ok

BMW E90 328i -OK
Code a new battery on 08-2011 M3’s
Can code injectors and new battery on 2008 BMW 135i
Foxwell NT510 find BMW 90 bad cylinder and I replace one:
Registering a battery is super easy. It gives you the option to say that you upgraded the Ah rating as well if you are having trouble finding an OEM spec battery.
