BMW 3 Series replacement car battery
A vital part of the automobile electrical system is the car battery. In essence, it serves as a container for the electricity that is given to the car’s electrically powered equipment. In light of this, it is important to keep the battery in top working order. The truth is that a car battery is a consumable that will eventually lose its effectiveness. To be more exact, the battery’s internal chemical processes won’t longer be able to generate electricity. A battery can only be used for 3 to 5 years before it starts to lose its ability to keep a meaningful charge. Installation of a new battery is necessary when this occurs. There is a chance that the battery’s energy will be squandered as a result of the deposits that have built up on the connection terminals. Poor connections can be caused by corrosion over time, which can impair a battery’s terminals. In other words, the battery will stop being able to be recharged by the alternator. It will eventually run out of fuel and stop functioning as a source of electricity. Debris from the cable and battery connection points may be removed, allowing the battery to be brought back to full performance and made usable once more. If the car wasn’t used for a while, the battery can also lose power. Recharging the battery might be able to improve the battery’s performance in this situation. You’ll need a battery charger to recharge the battery.
Important! It’s possible that some BMW 3 Series (E92, E93, E90, and E91) automobiles include an IBS (Intelligent Battery Sensor) technology. That indicates that your Service center has to register the newly replacement battery. Avoiding battery registration could result in a failure of the power management system and inaccurate readings on the on-board computer’s display.
Batteries that work best with the BMW 3 Series:
*Note: If more than one battery type is appropriate for your model, compare the specifications of the battery that is already installed in your car to those in the table below before selecting the best one.
Typically, the following equipment is sufficient for replacing batteries:
- 10 and 13 mm sockets or wrenches
- screwdrivers with flat-head and Phillips heads
3. The battery for the BMW 3 Series is under the right trim in the trunk.
Disconnect the negative connection on the old battery before removing it to begin replacing it. By doing this, unintentional short circuits between the positive battery terminal and the car’s body will be avoided. Make sure the cable does not make touch with the battery terminals when changing the battery. The minus (-) sign next to the negative battery connector serves as a visual cue (1):
1. Remove the positive terminal cover:
Positive connection disconnected:
Disconnect the battery’s venting pipe if it’s there. Some vehicles use battery ventilation systems to exhaust hydrogen-containing generated gases outside.
Remove the old battery from the battery compartment (notice that the battery is heavy and improper lifting could cause back injuries):
Before installing the new battery in the car’s battery compartment, do not remove the plastic terminal caps.
To guarantee optimal contact, if necessary, clean battery wires of any corrosion or debris before joining.
Instead of unplugging the battery, connect the cables, beginning with the positive terminal.
How big of a battery does a BMW have?
The BMW auto batteries you use should be compatible with your current model. BCI Group 94 49 H8 batteries are used in the majority of BMW automobiles, including those in the X3, X5, 3, 5, and 7 series. Given that they have nearly identical size, these batteries can also be used interchangeably.
The typical lifespan of an automotive battery for a BMW is three to five years. Your battery’s lifespan can be impacted by a variety of elements, including temperature, battery type, design, specifications, and driving practices.
Intelligent Battery Sensors are a feature of newer BMW cars, particularly those introduced after 2002. To prevent problems in the future, you must register your battery.
You can typically locate the battery and replace it on your own because it is a simple procedure. Just keep in mind that you will need to use a scanner equipment to register your BMW if it is a later model. Additionally, confirm that the new battery has virtually identical specifications to the old one.
Regrettably, you won’t be able to start your BWM if the battery dies. By utilizing jumper cables to link it to a healthy battery from another automobile, you can try jump-starting the battery. The vehicle can be jump-started from the front even if the battery is at the back.
What size battery is an E90?
Batteries with a nominal voltage in the 1.2-1.5V range and physical dimensions of 12.0 x 30.2 mm are known as N/E90 battery equivalents. Typically, these batteries are identified as N-cell or E90 batteries, but they may also bear the labels MN9100, LR1, R1, 910A, 910D, HR1, KR1, UM-5, UM5, etc.
How big is the battery in a BMW 320i?
Battery groups for the BMW 320i are either H6, H7, or H8. For dimensions, refer to the table below.
(1) Battery group codes made up of letters and numbers are used by the Battery Council International (BCI). These refer to the size of battery that will fit a certain vehicle the best (in terms of physical dimensions, terminal positions, and kind).

Where can I find BMW batteries?
The majority of brand-new BMW vehicles are constructed with their batteries in the trunk, unlike practically all other vehicles. Now that we’ve cleared things out, learning how to remove a car battery won’t take much time: Under the upholstery that covers your trunk, the battery is often found on the right side of your car.
How can I reset my BMW now that the battery has been changed?
One of the vehicles with the most advanced intelligent operating system in the world is the BMV. Therefore, the first thing you must do after every hit or replacement of an object in the car is to restart the entire vehicle.
This setup enables the computer to anticipate your next replacement requirement and alert you to it. After changing the battery, resetting the BMW computer is a quick and easy process.
- First, turn on the controller again.
- Step 2: Press “Trip” to activate it and make it light.
- Step 3: Hold down the “trip” button while continuing to press and hold it until the “Reset” button shows up on the screen.
- Reset in Step 4
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.
Should I reprogramme my car after changing the battery?
Yes. Your settings will need to be reset. The dealer will typically do it for free, but no guarantees can be made. If you replace a battery and anything was connected to the old one, such as the hose you mentioned, you must reinstall it. Everything is always put back on the same way I took it off. If you find yourself in need of help, think about calling YourMechanic. One of our mobile specialists may visit your house to service your batteries and make sure it was installed correctly. Thanks for reading, and good luck.

What happens if a fresh battery is not registered?
The charging current of the alternator is improperly set if a fresh battery is not registered. The replacement battery is not adequately charged as a result. This could lead to early failure. But don’t worry, the onboard electronics shouldn’t be harmed.
