If you’re looking at the various types of BMW car batteries for sale and wondering which will be best for your vehicle, read on. Here, we look at some general principles when it comes to replacing your car’s battery and in what respects the BMW battery might differ from those on other vehicles.

BMW Battery Or An Equivalent?

If you’re on a tight budget, but still need to get your vehicle’s battery replaced so you can travel from A to B, you’ll be looking for the most affordable unit for your vehicle. The typical BMW battery price from your dealership could well make your eyes water. However, as with most cars, there’s no need to shell out for an OEM (Original Manufacturer Equipment) component – which can cost a lot more – when a cheap version will do the job just as well.

Of course, OEM batteries have their advantages. First, you know an OEM battery will fit your car perfectly. And second, they’re often seen as being better quality than their aftermarket equivalents. If you plan to sell your car in the near future, the buyer may well prefer to see that the car’s been maintained with OEM parts.

However, in many cases, provided you do your research and assure yourself that the battery you’re buying is of sufficiently high quality, there’s likely to be only a negligible difference between the performance and lifespan of an alternate brand. You also tend to have a lot more choice when it comes to aftermarket parts, and the options are more widely available, than OEM ones where you may have to wait for a store to order what you need.

Check The Specs

The most important factor to check when buying a new BMW battery is not necessarily who’s made it, although as noted above, the quality of the brand is worth considering. But what you should be looking for is a battery that meets or exceeds the specifications laid down in your owner’s manual.

That generally means buying one of the same type – so if your car was fitted with an AGM battery, don’t try and fit an EFB or lead-acid one, or it’s not only the battery’s performance that will be affected. Fitting a lower-grade battery could damage the internal workings of your car and put your safety at risk. Having said that, if you have an EFB fitted, it is safe to upgrade to an AGM if you have the extra money to do so.

You should also look for the three usual specifications of your old battery – Cold Cranking Amps, Reserve Capacity, and the unit’s dimensions – and match or exceed them when buying a new one.

Specific To BMWs

If your BMW was manufactured in or after 2002, you’re probably going to need to get any new battery registered. BMW started to install Intelligent Battery Sensors (IBS) in the car’s engine control unit from this date. These sensors determine the power delivered to the battery, so the older the battery, the more power is used to recharge it. Fitting a new battery without informing the car’s ECU means it could receive too much charge, shortening its lifespan and causing possible performance problems. Ask your garage about the registration of your new car battery.

how much are BMW car batteries for sale


How much does a car battery cost in the UK?

Buying a new car battery in the UK is likely to cost you between £60 to £185, depending on the type of battery, the manufacturer, the length of any warranty offered, whether it’s maintenance-free and whether you need advanced features to support, for instance, start-stop technology.

How long do BMW car batteries last?

Dealers selling BMW vehicle batteries often estimate that they will last anything between two and five years. How you treat your car battery is a big factor in its lifespan, though. Look after it well and take the car for long drives periodically, and you should get five years or more from it.

How do I know if my BMW battery is dying?

Here are some typical warning signs:

  • Your engine cranks, but won’t start.
  • Your engine refuses to crank or start at all.
  • Your lights don’t come on.
  • Intermittent issues: if your car starts fine one day but won’t the next, it’s becoming unreliable.

If you see any of these signs, start checking out the BMW battery replacement cost in the UK.

How do you charge a dead BMW battery?

Ideally, charge a dead BMW battery when removed from the car and use a 12-volt trickle charger for up to 24 hours to ensure it’s fully charged. If you leave the battery in the car, use the jump-start terminals under the bonnet. If the battery won’t charge, start looking for a new BMW car battery for sale.

Does a BMW need a special battery?

You don’t need an OEM battery, but your new one must match the required specifications, e.g., if an AGM was fitted originally, replace like with like. Also, ensure RC, CCA, and dimensions match. BMW models later than 2002 are equipped with Intelligent Battery Sensors, or IBS, so the new battery must be registered to ensure it’s charged appropriately.

BMW Battery Replacement And Registration

It’s easy enough to replace your BMW’s battery yourself, but you may need expert help to register it. BMW models from 2002 or later are equipped with Intelligent Battery Sensors.

The car’s onboard computer adapts the speed and the battery is charged according to its state. Failure to register a new battery means the old settings will be used which can shorten the unit’s lifespan, affect its performance or even damage your car.

Consult your garage about registering, programming, and coding when fitting a new BMW battery.

The Right Way To Charge Your BMW Car Battery

Here’s a quick guide to charging your BMW battery:

  • Open the bonnet using the release lever.
  • Remove the car key from the ignition.
  • Locate the battery and attach the charger’s positive clamp (red) to the battery’s positive terminal.
  • Attach the negative clamp (black) to the negative terminal.
  • Plug the charger into the mains or an extension socket.
  • Wait for the battery to charge fully, which can take up to 24 hours.

Then, test whether your car will start. If not, your battery is probably dead so look at replacement BMW automobile batteries on sale.

Tips to Repair and Maintain Your BMW Battery

Replacing any car battery is expensive, and that’s certainly true for a BMW. So what steps can you take to ensure your new battery lasts as long as possible? Here are a few tips:

  • Keep your car out of direct sunlight and extremely cold temperatures. The former can cause battery fluids to evaporate, the latter can cause the battery to struggle to start the engine. If you don’t have a garage, park in shade or sheltered spots as much as possible.
  • Keep an eye on battery fluid levels if you have an unsealed unit – top up with distilled water when necessary.
  • Clean any corrosion off battery terminals routinely.
  • Have your car and battery serviced regularly by a mechanic.
