How to Register BMW Battery Yourself
In this guide, you will find step-by-step instructions on how to register a BMW battery yourself.
What you will need
To complete BMW battery registration yourself, you will need a scan tool that can carry battery registration.
Popular scanners that you can use to register a new BMW battery.
- Foxwell for BMW NT510
- Can only be used to register a new BMW battery with the same specs as the original.
- Carly for BMW
- Can be used to register a new battery. Limited coding functionality.
- Autel MaxiDAS DS808
- Can be used to program and code any type of battery including AGM and lead-acid. Even if the replacement battery is different than the original.
- BMW INPA Software (INPA K+CAN)
These instructions apply to 2002 and newer BMW models including 1, 3, 5, 6, X1, X3, X5 series.
Replace BMW Battery
The first step in the process is to replace the battery on your BMW. Aim to install a new battery with the same specs or as close as possible as the old battery.
Locate OBD-2 port
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 need to open. You may also find a cover on the port that you need to pull out. Plug the BMW scan tool of your choice into this port. Remember generic OBD2 scanners cannot perform 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 you press the start button. All the dashboard lights should turn on. The engine shouldn't be running. You won't be able to perform BMW battery registration procedure if the engine is running.
Complete BMW Battery Registration Procedure
The last step is to register the new BMW battery. The instructions in this step will vary depending on the scanner that you use.
See the instructions in the next section.
Foxwell NT510 Notes
Foxwell NT510 is more than just an OBD2 scan tool. It is capable of reading and clearing fault codes from multiple BMW systems.
You can use this scanner to read and clear codes from modules such as engine, airbag, transmission, ABS and more.
- Can only register a new battery with the same specs as the original.
- Make sure to update your Foxwell scanner to the latest software via the Foxwell website.
- Foxwell support is typically very slow to respond.
Register BMW Battery with Carly
You can use Carly and your Android or iPhone.
What we used:
- Carly Bluetooth adapter (Check Price)
- Carly Pro App ($60)
- Carly Battery Registration Addon ($15)
Carly allows you to perform registration and coding in BMWs. While Carly is a great BMW scanner, you need to be cautious as you can easily damage your vehicle with this little adapter if you accidentally stop the battery registration process in the middle.
INAP Battery Registration Procedure
BMW INPA K+CAN setup which requires a laptop. INAP is more complex to setup and can be difficult for many owners. Not recommended if you do not have experience with the INAP software.
- Connect OBD-II Cable to your OBD-II port. Turn on your laptop, then run the INPA software.
- Select “MODEL”–>Body–>Power Module
- Press “F6” to Activate
- Press”F2” to select “Control2”
- Press “F7” to select “Register battery replacement”
- If registration is successful you will get “Register battery replacement Activated properly”
These steps will register a new battery with the same specs. These steps will not code a new battery with different specs.
What is BMW Battery Registration?
BMW battery registration was introduced in 2002 and most BMW models after that require that you perform battery registration for best battery life and avoid electrical issues.
If your BMW is older than 2002, you don't need to perform battery registration.
During the BMW battery registration process, the following happens:
Battery capacity is set to 80%
The current Odometer reading is stored
Delete stored battery statistics such as:
battery charge level.
Stored temperature statistics are deleted
Show When do I need to register BMW battery?
Every time you replace the battery on a 2002 and newer BMW you need to register it. If your new battery has different specs than the old battery you need to code the new battery in addition to registering it.
Can I replace the battery myself and drive it to the mechanic for the registration?
Yes. This is ok. No damage will happen if you have to drive your BMW for a few min. It is the long overcharging or undercharging that can shorten the life of the battery or cause problems.
What's the difference between BMW Battery Registration and coding?
Our members often ask what's the difference between BMW battery registration vs. coding. Registration procedure clears the charging history of the old battery and tells your BMW that a new battery is installed which allows the car to charge the battery properly.
What is BMW Battery Coding?
Ideally, you should avoid installing a battery with different specs but that doesn't always happen. If you do install a battery with higher or lower capacity, BMW has different charging maps (profiles) for each battery, such as 80Ah, 90Ah or 110Ah batteries. You will need to perform coding to let the DME module know that you changed battery capacity.
If you changed battery type, you need to complete battery coding as well. BMW charges lead-acid type batteries differently than AGM batteries.
You need to perform coding if you:
Change battery type from Lead Acid to AGM or vice-versa.
Change the battery capacity.
Why do I have to perform BMW battery registration?
Yes. Don't skip battery registration. If you don't have a scanner, find an independent repair shop that can complete this for you. Some may only charge 0.5 hr of labor.
Which BMW models need battery registration?
Most 2002 and newer models. E61, E63, E64, E65, E66, E67,
E70, E71, E72, E81, E82, E84, E87, E88, E89, E90, E91, E92, E93, F01, F10.
Should I reset error codes?
If you had a BMW battery that was failing it is possible that a low voltage error codes have been triggered and stored in various systems. Perform a scan of all system and clear any codes that may have been stored. This procedure should also remove any Safe Mode including Energy Saving and Transport Modes.
