How do you replace a battery
A car battery is one of the most crucial components of any vehicle and will require replacement at least once throughout a driver's lifetime. However, replacing a BMW battery does not have to be the most difficult DIY project, and you can even save some money by doing it yourself. Knowing the amount of work needed to replace a battery is the key to success with your DIY project.
The first step is to identify the type of battery your BMW utilizes. There are three types of batteries, each with its own pros and cons. One of the most well-known is a lead-acid battery which is composed of lead and sulphuric acid. It generates electricity through an chemical reaction and recharges itself with the help of your BMW. Other types of batteries in BMWs include Gel or Absorbent Glass Mat. These batteries have similar operation but require different installation and handling.
Once you have a clear picture of the type of battery your BMW has and you know the battery's name, it's time to replace the battery that was in use. Many auto parts stores have a system that matches the BMW model and use the correct battery. This can help you save time. You may also want to look in your owner's manual which will likely include the type of battery required for your particular model.
To replace the battery on the BMW key fob, switch off your vehicle and remove the blade made of metal from the valet key or a flat screwdriver to access the lock cylinder. Remove the liner from the fob and locate the battery. After you have removed the battery, clean the terminal connections, and then reinstall them with care. Be careful not to tighten the brackets too much because this could damage the battery case. Connect the positive terminal first, then the negative. Last, reconnect the upholstery to its normal position.
Registering your new battery is an excellent thing to do. This will allow the engine control module, also known as the DME, be aware that you have a new battery and it won't be unsure about which one to charge. It will also reset the battery's age statistics, which could help avoid charging too much for your new BMW battery in Smyrna or Alpharetta.
