I always charge all my batteries with https://www.skyrc.com/iMAX_B6mini_Charger
It supports all battery types and you can attach a velcro strap with a temperature sensor.

It would be interesting if you could measure the internal resistance of those damaged NiCD (with a charger, or multitester). At least in LiPOs, that value reflects the "health"of the battery.

thanks eried, that looks like a good charger, I'll keep it in mind if I decide to return to rechargeables.

I threw that damaged pack away, I was so mad at it. The battery cover on my 65 is a bit warped as a result of the overheating, but the calc itself is fine, fortunately. One plastic slide on the cover works fine but the other does not, but one slide is enough to hold it in place.
