How do you replace a battery
A car battery is among the most crucial components of any vehicle. It will require replacement at least once in the lifetime of a driver. However, replacing a BMW battery doesn't have to be the most difficult DIY project, and you may even save some cash by doing it yourself. The key to success with a DIY battery replacement is knowing the amount of work it will take.
The first step is to identify the type of battery your BMW uses. There are three kinds of batteries each with its own pros and cons. One of the most well-known is a lead-acid battery, that is made up of sulfuric acid and lead. It produces electricity through a chemical reaction, and recharges itself when you use your BMW. Other battery types found in BMWs include Gel or Absorbent Glass Mat. These batteries have similar operation but require a different installation and handling.
It's time to replace your old battery once you know which one your BMW uses. Most auto parts stores will have systems that match the BMW model and make with the correct battery. This can save you time. You could also look at your owner's manual, which will likely include the battery type required for your particular model.
To replace the battery on a BMW key fob, shut off your car and then remove the metal blade of the valet key or flat screwdriver to reach the lock cylinder. Then, take off the fob's liner and locate the battery. After taking the battery off, clean the terminal connections and then reinstall them using care. Do not tighten brackets too much, since they could break the battery case. Connect the positive first before connecting the negative. Finally, connect the upholstery in its normal position.
Registering the battery you have purchased is an excellent idea to do. This will inform the engine control module, also referred to as the DME to know that you've got an updated battery and it won't be confused which one to charge. This will also reset the battery's age statistics to ensure that you don't overcharge the new BMW battery.
