Also in my NiCad packs there are 3 contact points +, - and there is a third,
what is it for? Inside the pack it is wired to a little thing about 1"long,
1/4" wide and 1/8" thick.

Could I use NiMH in place of my NiCad?

It's my understanding that NiCad excels in applications with big,
short-duration current draws, as in power tools. NiMH is more suited to
steady draw at lower current, with few peaks.

Of course, I have nothing to base that on.
