BMW battery coding is quite simple and takes no more than 15 minutes when done with the assistance of a BimmerTech specialist. You will be guided through it step-by-step by our expert. This is what you should do, then:
- Make sure your new battery is securely installed in your trunk using our battery installation instructions, and be ready for a remote BMW battery registration.
- As soon as you’re prepared to begin your coding session, check your Wi-Fi connection and start a chat with your BimmerTech professional.
- Under the dashboard on the driver’s side, look for the OBD2 port. Connect the OBD port to your laptop’s Ethernet port or external USB-RJ45 converter when the expert instructs you to do so. These are essential tools for registering your BMW battery. You’ll need to know your vehicle’s model code to decide if you’re going to use an Ethernet port or the USB port on your laptop. You’ll need a USB adaptor for vehicles with the model code “E” (such as the E90, E60, etc.). The Ethernet port would be the best choice for you if your car has a model code of “G” (e.g., G11, G30, etc.) or “F” (e.g., F30, F10, etc.).
- The battery registration process will thereafter be carried out by the BimmerTech expert.

Why register the replacement battery?
The servicing procedure “Register battery replacement” must be executed after installing a new battery. To let the power management system (software in engine electronics and an intelligent battery sensor) know that a new battery was put in the car, the battery replacement must be registered. The power management won’t work effectively if the battery change is not registered, which could result in certain tasks being restricted by particular electrical consumers being turned off or having their power consumption lowered. Power management will charge the new battery as if it were the old, worn-out battery, resulting in the replacement battery failing sooner than expected.
Important! The on-board computer’s display may show inaccurate values if the new battery hasn’t been recognized because of outdated information in the power management system (check control message “Recharge battery” appears even though the battery is new).
The power management in the Digital Engine Electronics (DME) or Digital Diesel Electronics (DDE) is alerted by a servicing function when a battery needs to be replaced. The following actions are carried out:
- 2. Changing a battery with a different capacity but the same kind (registration/conversion)
- 3. Changing to a new type of battery (for programming, conversion, or registration)
- 4. Software updates for the entire battery management system
For vehicles with EfficientDynamics, changes to the charging profile also impact how the Start/Stop system functions.
Car 1:
The battery is being replaced with an identical one. To inform the car that the battery is new, you register replacement so that the charging profile can be modified appropriately. If you don’t, the car will try to charge an outdated battery and eventually fail.
Car 2:
You replace a Standard LA battery with an AGM (or vice versa). Because the charging profile will be for the wrong sort of battery and accelerate battery failure, if you don’t register the replacement, it will toast the new battery for similar reasons to Car 1 but even worse. You MUST utilize a “conversion” in this scenario to switch the battery type. Register a replacement after that.
The vehicle must remain stationary with its new battery installed for at least 3 hours after a battery replacement. Until then, it is impossible to determine the new battery’s charge level with any degree of certainty. Possible The battery’s complete discharge-related Check Control signals are then hidden.
After a power supply interruption, some systems’ range of use may be constrained. Individual settings might also be lost.
Depending on the equipment specification, settings or activations are required. For instance:
- Autonomous engine start-stop function (MSA) vehicles: The MSA function is only operative after a learning period (the vehicle must not be awakened for approximately 6 hours).
The lifespan of a battery in these cars, whether an AGM or ordinary battery, can be significantly shortened by skipping the battery registration step. On a late model BMW, skipping battery registration can be one of the problems that results in premature battery failure. For more information, see the topic on Energy Diagnosis.

How much does it cost to register a BMW battery?
The charges may end up being more than you had anticipated when you visit the auto shop to replace your old battery with a new original BMW battery. The cost of registering the battery is about $200.
On the other hand, BimmerTech provides a battery registration service at a much lower cost. Visit our coding website to find out the precise cost of the service and the cost of the coding cable.
Is registering a BMW battery required?
BMWs with IBSs are required to log the type, capacity, and timing of the battery replacement. For BMWs with IBS, battery replacements DO NEED TO BE REGISTERED (Intelligent Battery Sensor)
What happens if my new BMW battery isn’t registered?
The new battery-ECU matching step is skipped, causing the ECU to fail to identify the battery as new and continue to operate the charging cycle as if it were the old battery. This reduces fuel efficiency and severely reduces the new, mismatched battery’s service life. In the long term, neglecting the battery registration service results in spending more money at the gas pump and on replacement batteries.
This new battery-ECU matching service is understood and routinely offered by a respected and skilled BMW service and repair facility, like Autoscope, to maintain the car’s design goals, operational effectiveness, and ownership economies.
Can Carly register her BMW on a battery?
In order for the car’s systems to be informed of the change when a new battery is installed, this battery must also be registered in the control unit. You can register any battery and battery type that is compatible with a BMW car using the Carly app. You can avoid going to the dealer or mechanic by doing this! Remember that you must first read out the battery to determine whether it is supported. Visit this page to see if your BMW model is compatible with this feature or any others.
What is supported depends on the built-in hardware and software of your specific car as well as the construction year. Use the Carly adapter to connect to your vehicle, and then use the Carly app to see what functions for yours. The Carly solution is always being improved, therefore after the video was shot, the app’s design may have changed and/or new features may have been introduced.
Can an OBD2 scanner detect a BMW battery?
A BMW OBD2 scanner must be used for battery registration (also known as a BMW diagnostic scanner or code reader). The OBD2 port underneath your vehicle’s dashboard is where the BMW scanning equipment is simply inserted in to establish an electronic connection with the engine control module (DME). The next step is to navigate to the appropriate screen and press a button to notify the DME that a new battery has been fitted. Please check our step-by-step guidelines below for more information on how to register a BMW battery.
We strongly advise buying a BMW scanner tool if you’re a home mechanic or enthusiast and don’t already have one. As essential to your toolkit as a set of socket wrenches, a BMW obd2 scanner will pay for itself after only one repair. The same one we used for this post is available for purchase in the components list below or by clicking here.
If you own a BMW and need to replace a dead battery without a diagnostic scanner, we advise visiting your neighborhood independent repair shop and asking them to handle it. They will probably conduct it for a minimal price and it takes less than a minute.
Includes thorough part diagrams, part numbers, and links to buy all necessary parts to do this repair.
With the help of a professional diagnostic scanner, you can read DTCs, find defective O2 sensors, verify the readiness of your emissions system, switch off the CEL or MIL, reset the monitor, read real-time data, get your car’s VIN, and do a lot more. This is the only BMW diagnostic scanner you will ever need, regardless of whether you are a do-it-yourself mechanic at home or work in a professional repair facility.
The process of registering your battery with a BMW obd2 scanner is quick and easy. Please be aware that the engine must be stopped and the ignition turned to position 15 (the AC must be blowing) in order for the battery to be successfully registered, regardless of the brand of diagnostic scanner or software you are using.
- Find the OBD2 port on your car. The port is often found either under the dashboard or inside the driver-side footwell in BMW vehicles.
- Turn the ignition to position 15 and insert the scanner into the port (dashboard lights on and AC blowing). DO NOT TURN ENGINE OFF!
- Launch the BMW scanner tool and locate the car.
- Locate the screen for battery management. Depending on the brand and model of your scanner, it is typically found under Special Functions.
- Select Register Battery Change, then adhere to the directions.
- At the conclusion of the registration, you will be informed that it was successful.
- If the battery registration error message appears on the screen, make sure the ignition is in the position 15 position and the engine is off (dashboard lights on and AC is blowing). The main cause of registration failure is this. If the engine is running or the ignition is not in position 15, the battery won’t register.
Can a BMW battery be changed?
The two-year limited guarantee on all BMW OEM parts includes unlimited mileage, but if your battery is more than two years old, you’ll need to get a replacement. How much does a battery replacement cost? For components and labor, replacing a BMW battery normally costs between $300 and $500.
Can any battery be used in my BMW?
Finding a great BMW battery is one of the most crucial factors to take into account if you want the best for your luxury vehicle. For the best performance on the road, you must purchase a BMW car battery that satisfies the strict criteria of the vehicle.
The 5, 6, and 7 Series BMW vehicles typically have very high features. These automobiles need a lot more energy than your typical car does, thus we strongly advise obtaining them strong batteries.
You must be aware of your vehicle’s needs before purchasing a BMW battery. An Absorbent Glass Matt (AGM) battery is strongly advised for modern BMW vehicles with start-stop technology since it can handle the increased energy demand. However, you can also utilize an Enhanced Flooded Battery (EFB) if you want to buy something for less money.
Just keep in mind that you should only replace the original AGM battery in your BMW vehicle with another AGM. Because these vehicles weren’t intended to be utilized with EFBs, downgrading will cause battery and engine problems with your BMW. On the other hand, if your BMW came with an EFB at the factory, switching to an AGM battery won’t cause any issues.
EFBs outlive ordinary batteries in terms of longevity. They were created specifically for entry-level start-stop vehicles, so they can easily handle the rigorous needs of the majority of modern automobiles.
However, you should always choose an AGM battery if you want to spend more money on a more potent BMW battery. Although these batteries are made for start-stop vehicles, they are also compatible with other energy-consuming vehicles.
In comparison to conventional batteries, they offer a three times longer cycle life and may be utilized in all kinds of weather. Additionally, an AGM battery is necessary if you frequently use the car’s accessories.
BMWs with typical power requirements can be powered by standard automobile batteries. Therefore, if your car doesn’t have high-end gadgets or a start-stop system, you don’t require a special BMW car battery.
