Repacking DynaTAC battery (SNN4211A)

I’m really wanting to repack this battery, and am looking for a way to open it without destroying it. This battery actually worked great as of last year, but now it only lasts for about a minute or so (One of the cell must have failed). I want to repack it with
Ni-Mh cells, which should be much better that Ni-Cd. I just need to find a way to open the case without ruining it.

As stated in the title, the pack I want to rebuild is an SNN4211A.

Thanks!

Hi. I want to do this too.
The later model battery packs, such as SNN4040A, can be opened without too much difficulty, I have re-packed one of these.
But the earlier model batteries are almost impossible to open I find, without wrecking the casing.
For sure, most of the Dynatac batteries I have had are pretty much stuffed & need repacking.

Is the SNN4211A a later one? Mine came off of a 1993/94 (forget which year) Ultra Classic.
