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.

Can a BMW battery be replaced without reprogramming?
Let’s first focus on what BMW battery registration genuinely is before delving into the procedure. Battery registration, to put it simply, is the process of notifying your car that a brand-new battery has been installed. Importantly, it must be done every time you replace the battery in your BMW, model year 2002 or later.
The car adapts the amount of energy required to recharge to operate at peak levels as your battery ages and gradually loses its ability to charge. The battery needs more charging the older it is. By registering your battery, you can inform your engine control module (also referred to as DME — Digital Motor Electronics) that a new one has been installed. As a result, the vehicle will reset the old battery statistics and won’t attempt to overcharge the new battery under the assumption that the old one is still in place.
In addition to registering, you must also code your BMW computer. No matter how different or similar your new battery is from your previous one in terms of specifications, it will still be necessary each time you change it.

Does BMW require a unique battery?
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.
