After a little more research on battery registration I found that if you replace a BMW battery with the same amperage battery registration does little to nothing at all. It’s when you change to a different than oe spec things go a little haywire as the computer does not recognize the change in amps unless told to. The article I read said that if you replace the battery with the same one and don’t register it there might be a 1% reduction in battery life. The article was a technical one and not clickbait, so it may have some veracity. I wish I would have kept it so I could link to it.
