$500 for a Battery?!
I took my '07 M6 into Tischer BMW a couple of days ago for a, "pre-purchase inspection". I bought my vehicle from Arena Motor Group in Owings Mills, and even though I think they insure their vehicles for sale are well serviced, I wanted a second opinion while the 30 day warranty from Arena was still in effect. Tischer didn't find anything wrong, but did note that the battery was the one that came with the vehicle originally, so it probably dated to 2006. Anyway, Tischer said that I was probably looking at having to replace the battery within the next couple of years (BTW, my M6 only has 20,000 miles). They said the cost of the battery was in the neighborhood of $300, and to install it was another $200.
Someone please tell me why the battery is so expensive, and why the amount Tischer would charge to install it would be almost for the cost of the battery. What is so unique about these batteries, and what's the procedure for changing them? Thanks.
