Thanks to dodgyken, it will be easy to find a replacement.
Dimensions are: 242 x 175 x 190
So I guess that is the Banner Uni Bull 50 300

It's a quite common battery, used in a lot of BMWs.

So it should be quite straightforward to find the Varta, Bosch verions (just to name two common, well known, brands).
