Car batteries can be expensive, especially for top-end vehicles. Many BMW vehicle owners may therefore appreciate a few tips on how to get the best value for money from their battery. Here in this blog, we'll give you some insight into what you can do to properly maintain your BMW battery, thereby prolonging its lifespan. By following these tips, it'll hopefully be quite a while before you have to buy a BMW car battery replacement.

where to find a bmw car battery

1. Park your BMW in the shade or an indoor garage

Extreme heat from the sun can be damaging to BMW batteries, and indeed any car's battery, especially if exposed to high temperatures for long periods. Parking your car indoors in a garage when it's not in use is ideal. However, not everyone has access to a garage; if this is the case for you, then try to park somewhere out of direct sunlight, like in the shade of a building or trees, to keep the car as cool as possible.

By parking out of direct sunlight wherever possible, you're not only prolonging the life of your BMW battery; it's much more pleasant for drivers and passengers alike to get into a car that doesn't feel like an oven on the interior!

2. Keep the battery hydrated

Maintaining the fluid levels in your battery is another important part of maintenance. If the fluid levels in a battery reach a low level or are completely depleted, that can result in a malfunction, preventing your car's engine from starting. Worse, it could fail while you are out on the road, which can be inconvenient at best, dangerous at worst.

Adding distilled water can provide a temporary solution to critically low fluid levels, though some car battery experts warn against this. Taking your BMW to a service centre to top up the fluid levels can be the best solution.

3. Check and clean the batteries connectors and contacts

Another important part of maintaining a BMW battery is checking the connectors and contacts. The contact points of a battery can become corroded or contaminated with dirt and dust over time. Grubby contacts and connectors can ultimately cause a malfunction, or in severe cases, can even cause your battery to stop working altogether.

what is the cheapest bmw car battery


Does a BMW need a special battery?

If you have a BMW vehicle with a start/stop system, you’ll be better off with an AGM battery. Although more expensive, these have the capacity to take constant starting and stopping (i.e., charging and discharging), and last longer, than standard starter batteries. Additionally, if your BMW has Intelligent Battery Sensors (IBS), you’ll need battery registration services.

Can I replace my BMW battery myself?

As with most cars, it’s relatively easy to fit a BMW automobile battery if you know what you’re doing. Make sure the new battery has the exact specifications as your current one. You will, however, need a scan tool for later BMW models to register the new battery.

How long do BMW car batteries last?

BMW batteries have a lifespan of two to five years. There are various factors that can reduce a battery’s lifespan, including the climate in your location, your driving habits, and whether you carry out routine maintenance. You can make the most of a battery’s lifespan by driving your vehicle for lengthy trips periodically and avoiding unnecessary use of electrical accessories.

How do I know if my BMW battery is bad?

It’s time to start thinking about a new BMW vehicle battery if you notice any of these signs:

  • Your engine cranks but doesn’t fire up.
  • Electric features like headlights and windows are less responsive than usual.
  • You're having a hard time starting your vehicle in cold weather and are jump-starting it regularly.

What happens if you don’t program a BMW battery?

If you don't reprogram your car for a new BMW automotive battery, you will lessen the battery’s lifespan because your vehicle will continue to treat it as if it is the old one, which means it will be overcharging it. Also, not reprogramming the ECU could adversely affect your car's electrical components. Therefore, it’s an essential task.

Manual Guide For Maintaining A BMW 525i Car Battery

Maintaining a BMW 525i car battery is easy because it is, in fact, 100% maintenance-free. The electrolytes inside it will last, provided you live in a temperate climate. When you need to charge it, only do this through the terminals in the engine compartment. Make sure the engine isn't running when you do this.

If you think you have a damaged fuse, fix or replace it to avoid overloading a circuit and prevent a fire.

How To Change A BMW Car Battery

Before you change your BMW car battery, you need to wear protective equipment including gloves and goggles. If you notice any battery leakage, it's best to let a mechanic do it.

The BMW car battery location is in your vehicle's boot or under the bonnet. After you've located the battery, remove the cables negative first before the positive. Disconnect everything that holds it in place. Remove the battery and clean the tray, clamps, and cables, then put the new one in position. Reattach the cables in reverse order, then ensure it's firmly fixed in place to avoid harmful vibrations.

Why Registering And Programming a BMW Battery Is Essential

You need to programme any new battery you install in your BMW to avoid overcharging it, not lessen its lifespan, and save your vehicle's electrical parts. This applies to any BMW model produced after 2002, when the manufacturer introduced Intelligent Battery Sensors. The upsides of these sensors are that you get improved fuel mileage and BMW car batteries tend to live longer.
