Yup - those covers are a pain.
Firstly - ignore the operators manual
1. Slide the battery out a bit (terminals all connected of course)
2. Slip the bottom part of the cover under the battery and push battery into its spot all the way.
3. I then push the LHS of the cover onto the locating pin and and down at the same time push forward towards the battery and then slide the RHS on to the locating pin. It feels like you will snap the damn thing but it does not.
Hope this makes sense. The 1250 is a beautiful machine.
