Car battery replacement for BMW 3 Series (F30, F31, F34)
Model years: 2011 - present
Car battery is one of the main parts containing vehicle's electrical system. Principally, it stores electric power, which is provided for electric devices within the vehicle. Therefore, it's significant to have the battery in a properly operating condition. Believe it or not, battery is not an everlasting unit, which will get exhausted after a period of time irreversibly. In other words, chemical reactions inside the battery will be incapable of generating electricity any longer. The life of the battery is limited to 3 - 5 years, after which it becomes incapable of being charged. That is why installation of a new battery is required. In some cases, battery will experience loss of electricity, caused by the dirt on connection points. After a while, battery terminals can get covered by white powder (corrosion), resulting in poor contacts. This is the reason why the battery can no longer be re-charged by alternator. Finally, it will go dead and no longer be able to provide electricity. Rubbing up cable and battery connections, might recover the battery to its original state and make it valid again. The battery might also become exhausted, if the vehicle was not used for couple of weeks or so. In such case, recharging the battery will possibly restore its efficiency. In order to perform a recharge, you will need a battery charger.
Important! Some BMW 3 Series (F30, F31, F34) 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.
