pefI too found the battery cover impossible to remove “by hand”. I used the clear plastic package as a cradle for the device,

then used a flat-blade screwdriver applied to the indent where you are meant to push by hand, and pushed hard at about

about a 45° angle. Finally got it open! I filed off a bit of the hook on the cover latch so hopfully it will be easier next time.
