Car battery replacement for BMW X1 five-door SUV (E84)
Model years: 2009 - present
Car battery is a major player inside vehicle's electrical system. In essence, it is a storage for electrical energy, which is provided for electric devices inside the car. Therefore, it's relevant to keep the battery in a properly operating condition. Sadly, car battery is not a permanent unit and will eventually become useless. More precisely, chemical reactions inside the battery will terminate and no electricity will be produced. Battery's life is limited to about 3 - 5 years, until it starts loosing the ability to hold a useful charge. This indicates, that installation of a new battery is advised. In some cases, battery's energy will be wasted, due to the soil concentrated on connection points. In time, battery terminals can get covered by a layer of white material (corrosion), which is a cause of weak connection contacts. This is the reason why the battery will lose the merit of being re-charged by alternator. Ultimately, it will get drained and no longer be able to provide electricity. Eliminating soil from cable and battery connections, might get the battery back to its normal operation and make it usable again. The battery may also get exhausted, if the car hasn't been driven for some time. In such case, battery recharge will likely restore its efficiency. To begin a recharge, you will need a battery charger.
Important! Some BMW X1 (E84) vehicles might be equipped with an IBS (Intelligent Battery Sensor) system. That means, newly replaced battery must be registered by your Service center. Avoiding battery registration might cause power management system failure, as well as incorrect readings on the display of the on-board computer.
