I see the wisdom of that now! I'll have to consider that.

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.
