Car battery replacement for BMW 1 Series (E87, E81, E82, E88)

Car battery is a fundamental connecting part of car's electrical system. In principle, it is a container for electricity, which makes electric mechanisms do work inside the vehicle. Hence, it's essential, that the battery is maintained in a fully working condition. Believe it or not, battery is an expiring unit and will get ineffective over time. In other words, chemical processes inside the battery will no longer be able to produce electricity. Battery's serve time roughly lasts 3 - 5 years, after which it cannot hold a useful charge. This is the reason why new battery installation should be considered.

There is an option, that battery will experience loss of electricity, because of the dirt on connection points. Eventually, white material (corrosion) can build up between battery terminals and cable connectors, which is a cause of weak connection contacts. This implies, that the battery will lose the merit of being re-charged by alternator. Sooner or later, it will run out of energy and no longer be able to provide electricity. Rubbing up cable and battery connections, might restore the battery to a level of full efficiency and prepare it ready to be used again.

The battery may also get flat, if the vehicle was left unused for a few weeks or so. In such case, battery recharge will possibly recover it. To begin a recharge, you will need a battery charger.

Important! Some BMW 1 Series (E87, E81, E82, E88) 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.
