Opening HP97 Battery Pack Grrrrrrr


A friend of mine has an HP97 with a battery pack that doesn't hold a charge any longer.

How do I crack it open to replace the nicads?

I assume they're C or sub-C size nicads inside?


A razor blade can break the welds on the ends & the units are glued back together. Batteries Plus will rebuild them for $20.


I rebuilt a couple of these. I used the sub-C Replacement Ni-Cds from Radio Shack with the solder tabs already on the cells. It was a tight fit, the solder joints must not use much space, or you will have a hard time getting the plastic case back together around them. If Batteries Plus will do this for $20, it is well worth it.
