Where Is the Battery in a BMW?The battery is one of the most important parts of a car. Without it, the vehicle wouldn’t start, and you wouldn’t be able to drive around Stratham, Portsmouth, or Exeter.

You may be wondering where the battery is in your BMW. The team at BMW of Stratham will provide that information. We’ll also explain how to charge a battery if needed and signs that you may need a new one entirely.

Read through the information below, then contact us for automotive service.

Location of the Battery

Location of the BatteryFor a BMW sedan or SUV, the battery can be found underneath the hood. Plus, you have starting air terminals by the engine for when the battery may need to be charged.

In a sedan like the 5 Series, the starting aid terminal in the engine compartment acts as the battery’s positive terminal. Then, a special nut is used as the negative terminal of a battery.

In an SUV like the X3, the battery’s positive terminal is also found in the engine compartment. However, a special connection on the body acts as the battery’s negative terminal.

The battery itself needs to be compatible to the automobile. Otherwise, it could impair vehicle functions or even damage various car parts.

Charging the Battery

You want to make sure that the battery in your BMW is always at a sufficient charge. This should especially be done after making frequent short-distance trips or if the vehicle hasn’t been driven in over a month.

Charging the Battery

To charge the battery, make sure the engine is off along with any electronic systems, such as the radio. Then, you’ll want to grab jumper cables and complete the following steps:

  1. Open the cover of the starting aid terminal.
  2. Attach one terminal clamp of the positive jumper cable to the positive terminal of the battery of the car that’s assisting.
  3. Attach the terminal clamp on the other end of the cable to the positive terminal of the battery on your BMW.
  4. Repeat steps 2 and 3 for the negative end.
  5. Start the engine of the working vehicle and let it run for a few minutes.
  6. Try starting your automobile and let both engines run for several minutes.
  7. If your battery is running fine, then you can disconnect the jumper cables in the reverse order.

Signs You Need a New Battery

If your BMW battery is unresponsive after trying to charge it, it may be dead. In that case, it’ll need to be replaced as soon as possible.

There are other ways to determine when your battery may be on its way out. One sign is that you have a slow engine crank. If it takes a bit longer to start up the car, the battery might be failing.

You might have a swollen or bloated battery case, which could happen under excessive heat. You’ll want to be careful since this could decrease battery life.

Finally, there could be a leak somewhere. This could also cause corrosion around the posts where the positive and negative cable connections are located. If you don’t remove that gunk right away, your BMW may not start.
