opening yaesu battery case
 

I have frozen the FNB28 battery case to open it up, and it has worked
perfectly, but when replacing the rechargable cells, do you keep the
components such as the thermal overload etc in the case, or has freezing
destroyed them?

Wire all EXACTLY the same way, just replace the cells out....
I have done this with my Standard packs, and doubled the capacity by
switching to better cells with the same dimensions....

I asked a similar question about ICOM packs (I didn't know about freezing)
and found that the problems that I had were related to corrosion,
which destroyed the microphone (ICOM had microphones in their packs
for a while, for full duplex operation) and a really cheap heat sensor
in an OEM (Periphex, circa 1995) pack whose leads broke off.

I replaced them with NiCad cells because I did not have a charger that
could charge NiMH cells properly and I had a bunch of them in the junkbox.
