How To Register a BMW Battery
In this guide, you will find step-by-step instructions on how to register and code a BMW battery.
BMW Battery Scan Tools
To register a BMW battery, you will need an OBD-II scan tool such as:
- Foxwell for BMW NT510
- One of the most popular BMW scanners. The tool can register a new BMW battery with similar specs compared to the previous battery. Installing a new battery with significantly different specs requires coding, which is not currently available on Foxwell NT510.
- AutoPhix 7910 BMW Scan Tool
- Similar to Foxwell NT510, and one of the cheapest scan tools able to register a BMW battery.
- Autel MaxiSys
- Professional Level Diagnostic Scanner. It can be used to program and code any battery, including AGM and lead-acid, even if the replacement battery is significantly different than the original.
- BMW INPA Software (INPA K+CAN)
- Require a laptop and familiarity with INAP software.
Registering a BMW battery is very similar to most of the scanners out on the market.
How to Register a BMW Battery
These instructions will help you register your new battery on a 2002 or newer BMW vehicle, including 1, 3, 5, 6, X1, X3, X5 series, etc.
Replace the battery in your BMW. If you need help with this step, see our guide on how to replace a BMW battery. We recommend installing a new battery with specs as close as possible to the old battery.
Locate the onboard diagnostic port under the dashboard near your brake pedal. The OBD-2 port on BMW cars has a small door that you will need to open. You may also find a cover on the port that you need to pull out. Plug your BMW scan tool of choice into this port. Remember, generic OBD2 scanners cannot perform the necessary BMW battery registration.
Turn Ignition On. Turn the key to option II. If you have a Push Start button, press it a couple of times. Don't press the brake pedal when pressing the start button. All the dashboard lights should turn on. The engine shouldn't be running. You won't be able to perform the BMW battery registration procedure if the engine is running.
The last step is to register the new BMW battery. The instructions in this step will vary depending on the scanner that you select. See the instructions in the next section on how to register a battery using various scanners.

What is the difference between BMW Battery Registration and Coding?
Our members often ask what the difference is between BMW battery registration vs. coding. The registration procedure clears the old battery's charging history and tells your BMW that a new battery with the same specs as the old battery is installed. The Engine Control Unit (DME) can charge the battery properly.
- Battery Registration
- Registration must be performed every time you change the battery on a 2002 and newer BMW. It lets the car know the battery installed is brand new.
- If the new battery has the same specs or very close to the old battery (CCA, CA, Ah, battery type), no coding will be required.
- Battery Coding
- You will need to carry out coding if you change the battery capacity or type in addition to the registration procedure. Coding is required if the new battery has different specifications than the old battery installed in the car.
- For example, if you install a battery with a higher or lower cranking Ampere rating, or switch between Lead Acid and an AGM battery, you will need to code (program) the DME. Otherwise, the DME may overcharge or undercharge the new battery and, therefore, shorten the battery's life.
