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.

Replacement BMW Batteries: Why Register a New BMW Battery?
Modern, late-model BMW batteries must be “registered” or matched to the onboard ECU for optimum operation and battery longevity, which is a frequently overlooked and underappreciated requirement. You might be asking why this is essential, and some online armchair experts could even argue that it isn’t really necessary and is just a way for the service provider to make more money by replacing the batteries. Some people turn to buying a new battery from an auto parts store, installing it themselves, and quickly learning that their battery needs to be replaced, again, in order to avoid the additional cost of registering their BMW battery.
How long does a BMW battery change take?
A battery replacement can be finished by our BMW service specialists in around 15 minutes. Expect the appointment to take longer, possibly up to an hour, if you have additional services like a brake check or tire rotation booked.
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.
What occurs if the battery in a BMW dies?
After you turn off your BMW, your battery continues to run for a while. After you leave, it will continue to run your radio, lights, clock, and even the security alarm for the car. Electrical issues with your BMW could cause some components to turn off while others, like your lights, remain on, draining your battery. When you leave your BMW, make sure all electric components are turned off.
How can I restart my automobile once the battery has been changed?

A BMW battery may be overcharged, right?
The battery is typically the most costly and crucial component of an electric vehicle. So, is it possible to unintentionally overcharge an electric vehicle and cause battery damage (or degradation)?
The quick answer is no, a battery in an electric vehicle cannot be overcharged. A built-in battery management and monitoring system ensures that the primary battery pack doesn’t overcharge in electric vehicles (such as Teslas, Chevy Bolts, and Nissan Leafs).
This is how it goes:
The charging process will be slowed down once the system notices that the battery is getting close to being fully charged. When the battery is fully charged, it will begin to “trickle charge,” meaning that it will be regularly charged at the same rate as its self-discharge rate. By doing this, the battery is kept fully charged without being overcharged.
It is important to keep in mind, though, that continuing to charge a battery until it is fully charged can cause it to lose some of its capacity over time and slightly shorten its useful lifespan.
Later on, along with other relevant electric vehicle (EV) issues, we’ll go into greater detail regarding the elements affecting battery health (lifespan).
How long is the warranty on a BMW battery?
Considering that all replacement BMW batteries are covered by a two-year/unlimited-mileage warranty*, it only makes sense to select dependable genuine equipment.
Do BMW batteries require programming?
Registration is necessary so that your vehicle is aware of the modified requirements and is able to adapt to the new battery settings. Otherwise, improperly coding your BMW battery could lead to a variety of electrical issues, including a reduction in battery life, the risk of overcharging or undercharging your battery, or, in the worst case scenario, serious harm to your car’s alternator and electrical system, which could cause your battery to fail before its time.
What kinds of electrical issues could there be? As a result of your automobile assuming that the battery life is low and attempting to conserve it, several modules of your BMW may turn off. So, at that time, it’s possible for your windows and mirrors to not close or open, your radio to not function, your interior lighting to not function, or other modules that are not required for starting or operating a car to fail.
What occurs if your 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.
Why is a BMW battery required to be registered?
Why is it required to register a BMW battery? It is crucial that you register, reprogram, or reset the change in the vehicle’s computer system after installing a new car battery. This will inform the computer system that the battery is new and will cleanly wipe the memory of the previous charging patterns. The reason for this is that the more recent BMW models have an electrical system that is very sophisticated and equipped with IBS (Intelligent Battery Sensors), which customizes the charging process to the kind and age of the battery.
It’s crucial to register the new battery using an electronic scanner in the vehicle’s BMS (Battery Management System), whether you’re switching from a traditional lead-acid battery to an Absorbent Glass Mat (AGM) battery or using an OEM battery. This procedure, which resets electrical components and sensors and clears fault codes, is referred to as a new battery registration.
The charging system in your car is reset during the BMW battery registration scanning process, and the battery capacity is set to 80%. Additionally, it removes any battery and temperature statistics relating to the old battery that were stored. It’s crucial to understand that nothing about the procedure will affect or reset the reading on your odometer.
Important Hint: In a car made only for AGM uses, never swap out an OEM factory-installed AGM battery for a regular lead-acid battery. AGM batteries can be used as a replacement for wet-flooded batteries, but don’t forget to register them. If the scanner only has an 85AH or 100AH choice, for instance, and your battery has a 90AH rating, always select the greater AH level.
Can I replace a battery on my own?
- To determine whether your automobile battery needs to be replaced, you should have it tested.
- Most automotive batteries can be replaced with a few simple tools and is a reasonably simple process.
- It is necessary to properly dispose of used automobile batteries because they are regarded as hazardous trash.
Instead than paying excessive garage or repair center charges, you can purchase your replacement battery anywhere, including online. Depending on your vehicle, car batteries might cost anywhere from $50 to $200. Once you get the battery, it usually takes 30 minutes to finish the process.
