Replacing A BMW Battery
You would think that replacing a battery in a car would be one of the easiest things you could possibly do. Not so for the BMW apparently. I have a 2005 525i E60 BMW, and in my research, for replacing the battery, I came across a tonne of conflicting information. Supposedly, BMW’s have a smart charging system that determines the best output for your battery, ensuring that its life is prolonged. Honestly, given how expensive everything else is with a BMW, I believed it at first.
