    I checked on the Optima web site and they do not show a battery for an M5 but I was not sure whether they did not make one or they did ot list one.

    someone on the 'other m5 board' put an optima in

    but it was smaller, so he had to use something to help keep in in place. Try a search on m5board dot com.

    Optima Battery?

    I have my 2000 M5 in my garage for the winter. I start it every two weeks just to get new gas thru the injectors. When I went to start it several weeks ago the battery was weak so I put the charger on it. When I went to start it today the battery was not strong enough to turn it over. The battery, I think it is the original OEM battery so it probably is time for it to be replaced. Has anyone had experience with the Optima battery in an M5. Do they have one that fits propery in an M5 without having to make special hold downs or have it flopping around in the battery compartment?
