The battery of the BMW 3 Series is located in the trunk. Placing the battery in the trunk is for achieving front-rear weight balance. Generally, the lifespan of a car battery is over 2 years. Models of the BMW 3 Series include: BMW 320i, BMW 325im, BMW 320lim, BMW 325lixdrivem, BMW 320li, etc. Taking the 2021 BMW 320i as an example, it is a mid-size car with body dimensions of: length 4719mm, width 1827mm, height 1459mm, wheelbase 2851mm, and a fuel tank capacity of 59l. The 2021 BMW 320i is equipped with a 2.0t turbocharged engine, with a maximum horsepower of 156ps, maximum torque of 250nm, maximum power of 115kw, and is paired with an 8-speed automatic transmission.
As someone who frequently helps friends with car issues, I'm very familiar with the battery location in BMW 3 Series: For most model years, it's hidden under the floor mat on the right side of the trunk or inside the left storage compartment. You'll need to open the trunk, remove the anti-slip mat or storage cover, and you'll find the battery cover underneath - just use a small wrench to remove it and access the battery itself. This design is primarily for weight distribution, making the front wheels lighter for better handling. If you're replacing the battery yourself, remember to wear gloves, turn off the engine, and disconnect the negative terminal to prevent short circuits. During regular maintenance, also check for corrosion on the terminals - this can extend battery life by about two years. Keep your trunk organized and avoid stacking items too high to maintain easy access to the battery compartment.
