How to Replace the Battery

A car battery is one of the most vital components of any vehicle. It's likely to require replacement at least once throughout the life of a driver. However replacing a BMW battery isn't necessarily the most complicated do-it-yourself project, and you can even save some money by doing it yourself. The most important thing to do an effective DIY battery replacement is knowing how much work it will take.

It is important to know the type of battery your BMW utilizes. There are three types of batteries, each with their own pros and cons. Lead-acid batteries are the most well-known, as they contain sulfuric acids and lead. It produces electricity by a chemical reaction and then recharges itself using your BMW. Other types of batteries in BMWs include Gel or Absorbent Glass Mat. These batteries operate similarly but require different handling and installation.

Be sure not to tighten the brackets too much, as this could crack the battery case. Connect the positive first, then the negative. Finally, connect the upholstery in its normal position.

Registering your new battery is also an excellent thing to do. If you do this, the engine control module (known as the DME) will know that the new battery is installed and won't be confused as to which one to charge. It also resets the statistics on battery age, which could help prevent overcharging of your new BMW battery in Smyrna or Alpharetta.
