I haven’t been too thrilled withNiMH battery longevity lately. I just replaced one in a cordless phone and acouple in my kids remote control cars that had stopped charging. They aren’tcheap and they don’t last forever. I would stick with a CR2032 in a coincell socket.

They're NiCads, and very different construction.

That's what the resistor and diode you remove are. It's a crap charging
circuit, but it pretty much works.
