The negative terminal of the BMW 5 Series battery is located on the right side of the trunk. Simply open the cover to see it. Taking the 2021 BMW 5 Series 525li as an example, its body dimensions are: 5106mm in length, 1868mm in width, and 1500mm in height, with a wheelbase of 3105mm and a fuel tank capacity of 68 liters. The 2021 BMW 5 Series 525li features a double-wishbone independent front suspension and a multi-link independent rear suspension. It is equipped with a 2.0T turbocharged engine, delivering a maximum horsepower of 184PS, a maximum power of 135kW, and a maximum torque of 290Nm, paired with an 8-speed automatic transmission.
I just bought a used BMW 5 Series and researched the battery location. The negative battery terminal is usually in the trunk – you may need to open the right-side cover or trim panel. That black terminal post is the negative, marked with a minus sign. When jump-starting, I always disconnect the negative first to avoid short circuits, which is safer. Note that locations vary slightly by model year – for example, the G30 series might have it under the trunk floor panel, so checking the vehicle manual is more accurate. For routine battery maintenance, watch for oxidized terminals and clean them to extend lifespan. Car batteries typically last 3-5 years, and regular voltage checks are crucial.
