Where is the battery located in a BMW 1 Series?

The battery in a BMW 1 Series is generally installed in the trunk of the car, next to the spare tire. Below is an introduction to the BMW 1 Series: 1. Interior: The new 1 Series largely continues the interior design of the previous model, with the upgrades in this new model mainly focused on the configuration. The new car is equipped with features such as the new iDrive system, active cruise control system, engine start-stop, and BMW remote services. 2. Powertrain: The new car is powered by three engines: 1.6T, 2.0T, and 3.0T. Among them, the 1.6T engine offers two versions with high and low power outputs, with maximum power outputs of 136 horsepower and 177 horsepower respectively. The 2.0T engine has a maximum power output of 218 horsepower, while the 3.0T engine in the BMW M135i xDrive can reach a maximum power output of 320 horsepower. The 8-speed automatic transmission has become the standard configuration across the entire lineup of the new car.

I once drove a used BMW 1 Series and encountered battery issues. Its battery is located under the floor of the trunk, not in the engine compartment. Open the trunk door, lift the carpet or remove the fixed padding, and you'll see the battery cover. After lifting the cover, the battery and its positive/negative terminals are clearly visible. BMW designed it this way to optimize front-rear weight balance for more stable driving. I once replaced it myself but forgot to turn off the engine, causing a short circuit – now I always remember step one is to turn off the ignition. The spacious trunk makes operation easier, but beginners shouldn't take risks as improper handling may damage the vehicle's electrical system. Regularly check the electrolyte or maintenance-free indicator – generally replacement is needed every three years to avoid cold-weather starting difficulties.

After getting the new car, I was always curious about where the battery was. Later, a friend told me it's a unique design of the BMW 1 Series—hidden under the trunk. Just open the trunk, remove the floor covering, and it's revealed. It's quite concealed but not hard to find, and the space design doesn't affect my usual luggage storage. Why is it placed there? My friend explained it's for better car handling, as the battery weight at the rear reduces sway. Once, when the car wouldn't start in the morning, I lifted the trunk to check and found the terminals loose—a simple fix solved the issue. The location is quite convenient for DIY; just have a wrench and gloves ready and be mindful of safety. The car feels more stable when driving, and the area under the trunk is less prone to dust accumulation, extending the battery's lifespan. Regular maintenance technicians also often remind checking the battery's condition.

The battery of the BMW 1 Series is located under the trunk floor. After opening the trunk, remove the luggage liner or carpet cover to directly access the battery. This location is convenient for maintenance, and it's recommended to turn off the engine during replacement to avoid short-circuit risks. The design intention is to balance weight and enhance driving feel. It is advised to inspect every six months, removing dust or addressing corroded terminals. Extra warmth is needed in winter to prevent power loss, with most batteries lasting three years. Professional tools can be used to measure voltage when necessary to ensure battery health.
