Woodstock battery holder

[jebem]

Thank you for sharing this idea, Bernhard.
I had the same issue after replacing the original Ni-Cd batteries on one of my HP-25 machines with a new set of Chinese 900mAh Ni-Cd batteries which obviously are a little larger than the originals.

To replace the batteries, instead of breaking the plastic holder at the usual place to remove the dead batteries (cutting the middle plastic strip at the batteries side), I prefer a different approach.

The battery holder is made of two plastic pieces welded together at factory. So to open it on the original place we can use a X-acto knife and lots of patience to not destroy the plastics (or your fingers...).

After inserting a new set of batteries, the back cover can be glued to the case.
