If you haven’t already changed the battery in your BMW and don’t know how to do it, here is a quick method. There are nine steps that make up the battery replacement process:
- Remove your key from the ignition after turning it off. Next, find your battery. In a BMW, where is the battery? The majority of the time, you can discover it within your trunk, either on the floor or on the right side. Located it? The battery liner should be removed.
- With a 10mm wrench, unplug the negative battery terminal right away, then store the cable.
- The cable must then be disconnected from the positive battery terminal. To complete the task correctly, lift up the red plastic cover and look for a 10mm nut; you must loosen it.
- The time has come to remove the brackets. Two brackets, one on top and one on the side, support the battery. First, you should unbolt the latter using two 13mm bolts.
- Take out the battery from the trunk, but be careful because it could be heavy.
- Take images of the battery’s model number and technical specifications before you install the new battery. When registering your battery, the BimmerTech expert will need this information very much.
- Now that the old battery has been removed, gently set the new one in its place. Just make sure the settings are correct.
- crucial step Secure the battery properly. You must reinstall the brackets in order to accomplish this, being careful not to overtighten them. If not, you could break the battery housing. Connecting a Liquid Lead-Acid battery to the vent house can stop the vent house’s gasses from accumulating within your trunk if you’re installing one.
- Finally, connect the battery terminals by connecting the positive battery terminal first, then the negative terminal, after cleaning the battery posts with a battery terminal brush.
NOTE: Purchase our Battery Registration service before you ever begin replacing or registering your battery, and choose a preferred date when you could replace and register the battery simultaneously. Make sure you can do everything in one day because battery registration is required following every battery change and needs to be done immediately after battery replacement.

What occurs with an unregistered BMW 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.
