bosch battery

I bought a spare Bosch Powertube 625 Horizontal battery for my e-160s about a month ago but realised I wasted my money and it's not gong to get used. It's brand new, still in the box and I'm asking £450 including postage (UK only).

I went to local bikeshop to update my bike, when i received bike they told me there is no update for my bike, but when i came home and checked bike has been updated... Anyone know what has been changed in updates? Purion Display...1.2.0.0 -> 1.4.0.0, driver unit...1.7.0.0 -> 1.8.6.0, powerback...

Hi, has anyone else experienced issues with Bosch service? I purchased a new Cube Reaction SL625 and the battery died on 3rd use. Been waiting 3 weeks and gone through major stress with Bosch - they have no stock!!
