Where is the battery located in a BMW 3 Series?

The battery of the BMW 3 Series is located under the trunk. Taking the 2021 BMW 3 Series Sport Package as an example, it is a mid-size 4-door 5-seater sedan with body dimensions of: length 4719mm, width 1827mm, height 1459mm, wheelbase 2851mm, and a fuel tank capacity of 59 liters. The 2021 BMW 3 Series Sport Package is equipped with a 2.0T turbocharged engine and an 8-speed automatic transmission, delivering a maximum power of 115 kilowatts and a maximum torque of 250 Newton-meters. It features rear-wheel drive with a front suspension using a double-joint spring strut front axle and a rear suspension using a multi-link independent suspension.
The battery location of the BMW 3 Series, I have to tell you, is usually under the floor cover in the right rear corner of the trunk. Just lift the trunk floor, and you'll see a removable plastic cover. This design improves the vehicle's weight distribution, reduces the burden on the front, and protects the battery from engine heat to prevent premature aging. If you're checking it yourself, remember to unlock the trunk with your key first, then gently lift the carpet or cover to easily find it. The battery's negative terminal is usually closer to the inner side of the rear. Be careful not to cause a short circuit when connecting. If the battery dies, changing fuses or jump-starting becomes much easier. I often recommend checking the battery's condition regularly to prevent leakage or corrosion because if this little thing runs out of power, the whole car stops working. A quick check before driving can save you a lot of trouble.
