BMW 1 Series battery positive and negative terminal locations: The red plastic cover under the engine is the positive terminal. The negative terminal of the battery has a cover directly above the battery. Red indicates positive, and black indicates negative. The battery positive terminals must be connected together. When removing or installing the battery, pay attention to the sequence of disconnecting and connecting the battery cables to prevent short-circuit discharge caused by the battery positive terminal coming into contact with the car body or other metal components through metal tools like wrenches during the process. The BMW 1 Series is a compact sedan launched by BMW Brilliance Automotive, with dimensions of 4462mm in length, 1803mm in width, 1446mm in height, and a wheelbase of 2670mm.
As a long-term owner of a BMW 1 Series, I often handle battery issues myself. The car's battery is usually located on the right side of the trunk. You can find it by opening the trunk lid and looking towards the right corner—the positive terminal is marked with a red cover, while the negative terminal is either black or directly connected to the car frame. BMW designed it this way to balance the vehicle's weight distribution, improving driving stability and handling. Every time I work on it, I make sure to turn off the engine and wear insulated gloves to prevent short-circuit risks. As a side note, the battery lifespan is typically around 3-5 years, so it's important to regularly check for corrosion on the terminals to avoid unexpected breakdowns. If you're unsure about the location, there might be a diagram label on the inner wall of the trunk—just refer to it for guidance.
Buddy, as a hands-on DIY car owner, I can tell you that locating the battery terminals on a BMW 1 Series is pretty straightforward. They're positioned at the rear right side of the trunk – just lift the plastic cover to reveal them. The red cap indicates the positive terminal, while the negative is typically an exposed metal point. Remember to turn off the vehicle's power before working on it to avoid sparks from accidental contact with metal tools. Last time I helped a neighbor with jumper cables, precise terminal location saved us a lot of hassle. BMW placed it in the trunk primarily to reduce front-end weight for better cornering agility. Maintenance tip: Occasionally brush the terminals to prevent corrosion – this extends battery life and takes almost no time.
