I think that parallel to the circuit board covers it. Otherwise it depends if it is lying face down to work on it or holding it up as to use it ;0)
What I did was cut the cell from the legs and use the legs as posts to connect the wires. There is a point to the bottom right (rig lying face down) where the battery can just fit with a couple of wraps if insulating tape to keep it from shorting. Fitting a cell without the legs in the original position would be difficult as it is stood proud of the board. You would also need to completely remove the circuit board to de-solder the legs from underneath.
