Odyssey PC625 / 2011 GSA

My 2011 GSA oem battery was giving up the ghost, but apparently not quite dead enough for BMW to replace under warranty (although it tested at 9.8 under load). I read several threads suggesting the Odyssey PC625 was a good replacement option, so decided to give it a go. With some help from JVB, and a utility knife and dremel, the Odyssey fit right in. Needless to say, I am very glad to have this powerplant with our daytime temps hovering in the teens.

GSA battery, a stock GS battery, and the Odyssey 625.

Remove this tray and the larger standard GS battery fits.

Some trimming of the fins and the PC625 fits.

But a seat bar trimming is in order.
