Your BMW battery feeds power to your car to start it and run its electric systems. If their BMW batteries aren’t properly working, car owners lose a number of the vehicles’ critical functions that can compromise performance, comfort, and even safety. One of the most parts of being a car owner is knowing when its battery should be replaced – after all, no battery lasts forever.
Your car batteries power the BMW’s sound system, air-conditioning, radio, engine, and many of the safety mechanisms built into the vehicle. With all these energy-intensive features supported by the battery’s power, it’s only natural that the unit will eventually lose its efficiency and need replacing.
There isn’t really an exact formula as to when car batteries should be replaced. It typically depends on how often you use your car and how many accessories the battery is powering on a regular basis, as well as how well you look after it.
To be on the safe side, make sure you have your batteries checked at least twice a year by a professional, especially if you use your car a lot. On average, BMW batteries in the UK tend to need replacing every two to three years.
In theory, any high-quality car battery could last up to five years. But in practice, many car owners don’t keep up with the regular maintenance requirements needed, so batteries tend to give up the ghost much sooner.
A good mechanic will be able to tell you during routine maintenance and servicing checks whether or not your battery is still good to go or if it’s liable to need replacing in the near future. They can also provide some excellent maintenance tips to help you get more years out of your battery.
BMW Battery Maintenance During Lockdown
With lockdown restrictions being implemented around the world in the midst of the COVID-19 pandemic, it’s understandable that many cars are not being used as often as before. But unfortunately, this doesn’t mean that car batteries experience less wear and will just retain their charge.
Remember that even when not in use, your BMW’s car battery will still drain over time. Some essential functions, like your car alarm, the clock and so on, continue to work even if your car is just parked in the driveway. In addition, the chemical process that results in discharge still occurs while your battery is not in use, albeit at a slower rate.
If your BMW battery is healthy, then it should still work just fine, despite the car not being used for two weeks or so. However, any period beyond that, and your battery might need to be completely charged to full again.
Experts recommend that, if you’re not using your car for long periods, you should let your engine run for around 15 to 20 minutes a week, just to make sure your battery stays in optimal condition. If possible, take your BMW out for longer drives every so often, so the alternator can recharge your battery.
Also, make sure you minimise the use of your car’s electrical systems if they’re not needed. Avoid turning on the headlights or the radio, or using the air conditioning before starting the engine, for instance.

FREQUENTLY ASKED QUESTIONS
Does a BMW need a special battery?
Newer BMW vehicles make use of a technology known as Intelligent Battery Sensors, or IBS. To take full advantage of their cars’ features, BMW car owners must register their new BMW vehicle battery each time they replace it at any BMW dealership or an authorised BMW shop.
How much does it cost to replace a BMW battery?
A BMW auto battery replacement will cost anywhere between £225 and £374, factoring in the parts and labour required. However, it’s worth noting that the price of parts and installation will vary depending on the model you’re getting a replacement for, and where you buy the battery, so be sure to shop around for the best prices to get the most for your money.
Can I replace my BMW battery myself?
There shouldn’t be any problem if you decide to replace your BMW battery yourself, especially if the replacement that you are getting is a battery with the exact specs as the original. However, you will need a scan tool to perform battery registration after you fit your new BMW battery.
How long do BMW car batteries last?
The lifespan of a BMW car battery depends on several factors, but typically these batteries can last between two and five years.
Can you jump-start a BMW battery?
You can jump-start a dead battery to get it to work again. However, you’ll need another vehicle with a healthy battery and a set of jump leads to charge yours. Although the usual BMW battery location is at the rear of the vehicle, you can still jump-start it from the front.
How To Replace A BMW Battery
- Wear safety glasses, then open the boot of your BMW.
- Locate the battery on the right side of the boot by lifting up the floor panel.
- Unfasten the top of the battery cover. Using a flat screwdriver, loosen the fasteners by turning them counterclockwise, then remove the battery cover.
- Using a socket wrench, remove the two bolts securing the protective bar.
- Loosen the nut on the negative (black) battery cable. Remove the cable, carefully preventing it from coming into contact with the terminal. Do the same for the positive (red) battery cable.
- Remove the old battery and replace it with a new one.
- Connect the positive (red) battery cable to the positive battery terminal first, then tighten the nut. Do the same thing for the negative (black) battery cable.
- Reinstall the protective bar and replace the battery cover.
BMW Battery Fire Risks
A recent fire risk has been discovered in BMW batteries for electric and hybrid engines. Apparently, when metallic debris infiltrates the battery cell during production, the battery may potentially short-circuit during charging, potentially resulting in a fire. If you’re unfortunate enough to receive a faulty model, then you could be in for some expensive repairs and replacement parts.
Because this has happened, people now appear to be thinking twice about transitioning to EVs, with drivers more likely to stick to more trustworthy petrol and diesel cars. That’s no problem in term of getting new batteries, though – compatible BMW units for these engines are still widely available.
Ideal Car Battery Voltage
Healthy car batteries have a voltage of at least 12.6v. Because of the way lead-acid batteries consume their charge, you should only test your battery’s voltage with a multimeter after it has been left unused for a while. Leaving your car static overnight will help you get the battery’s “resting voltage”, which gives a more accurate reading.
If your battery is in bad shape, you need a replacement. To get the best value for money on high-quality batteries, visit Orius Batteries’ store today!
