Where is the battery located in the BMW 5 Series?

The battery of the BMW 5 Series is located under the partition panel on the right side of the trunk, below the taillight. Simply open the cover to access it. Car batteries, also known as storage batteries, are a type of cell that works by converting chemical energy into electrical energy. Typically, what people refer to as a car battery is a lead-acid battery, which is mainly composed of lead and its oxides, with sulfuric acid solution as the electrolyte. The BMW 5 Series is a mid-to-large-sized sedan, with dimensions of 5106mm in length, 1868mm in width, and 1500mm in height, featuring a wheelbase of 3105mm and a body structure of a 4-door, 5-seater sedan. This model is equipped with a 2.0-liter turbocharged engine, delivering a maximum power of 135kW and a maximum torque of 290Nm.
When I first got into the BMW 5 Series, I was curious about where the battery was located. Later, when I replaced it myself, I discovered its clever placement—right in the trunk. Open the trunk lid, and in the right corner, there’s a small carpet or cover panel. Lift it, and you’ll find the battery securely placed. This arrangement is typical in models like the G30 generation. Why here? BMW engineers designed it this way to balance weight, reducing the impact of a heavy front end on steering for a smoother drive. Just be careful not to damage the cover when storing items. The first time searching for it can be confusing, so I recommend wearing gloves during the process. Disconnect the negative terminal before replacing it with a new AGM battery to avoid short circuits. If you’re a DIY enthusiast like me, a basic tool kit will suffice, but don’t force it if you’re unsure—damaging the wiring is a risk. Online video tutorials are incredibly helpful, and never skip safety steps for convenience. After all, battery issues can affect the entire car’s performance.
