Where is the battery located in a BMW 523?

The battery charging location for the BMW 5 Series is inside the right-side panel in the trunk. How the battery works: The working principle of the BMW 5 Series battery is to convert chemical energy into electrical energy. The lifespan of the battery is closely related to the vehicle's condition. Battery maintenance methods: Avoid parking the car in an open parking lot for extended periods. If long-term parking is necessary, remove the battery to prevent it from freezing and getting damaged. In winter, the car engine is harder to start. Each attempt to start the car should not exceed 5 seconds, with a minimum interval of 15 seconds between attempts. If the car fails to start after several attempts, check other aspects such as the circuit, ignition coil, or fuel system. Avoid multiple uninterrupted attempts to start the car, as this can cause the battery to over-discharge and burn out.
I often drive a BMW, where is the battery for the 523 model located? It's under the floor in the lower left corner of the trunk. I've found and checked it multiple times myself: lift the trunk carpet, and you'll see a small plastic cover or panel that can be pried open with a screwdriver or coin, revealing the battery inside. BMW designed it this way for better weight distribution, ensuring more stable driving, especially at high speeds. When replacing the battery, first remove the key—safety first; then disconnect the negative terminal to prevent short circuits, and tighten the connections after installation. Regularly checking the battery voltage is important, as it tends to drain faster in winter. It's recommended to measure the voltage every six months to avoid getting stranded on the road. Be careful not to touch metal parts when handling it yourself, and if unsure, it's best to visit a professional shop.
