What is the S2 stock battery size/code?

[desmo888]

Hi all,
I am installing a stock S2 battery box under the rear seat of my e//S2. I need to know what the stock battery code (size) is for the stock battery for proper fitment. No info available here in the USA for S2's.
Also, anyone running an Optima red top? I may go that route.

TIA.

About 175x175x280mm. Usually about 64-70Ah depending on manufacturer.
Optima is probably too high.

I got one overhere and it turned out to be a standard DIN 065 Style shape battery according to the book, and it must be right as it fits perfect and starts with no problem.
