So I guess it is Ok to live under a rock most of the time, but every now and then coming out can just be fun. I was reading about different brands of batteries for one of my cars. I ended up on some BMW site discussing the batteries I was interested in. As I'm reading along I am wondering what the heck these people are talking about when they need to buy a cable and software with their new battery purchase. After a few posts it became clear they were needing all this extra crap because they had to download the new battery information into their vehicles computer. Of course I got a chuckle out of this nonsense. As I read further I came across a post that said, "doesn't anybody on this forum find it ridiculous that we have to download battery information to our car ? What happened to disconnecting the hold down and the cables and just installing a battery and being done with it ? " I couldn't of said it any better...
