RE: [korgpolyex] Re: memory backup battery mod

I haven't been too thrilled with NiMH battery longevity lately. I just
replaced one in a cordless phone and a couple in my kids remote control cars
that had stopped charging. They aren't cheap and they don't last forever. I
would stick with a CR2032 in a coin cell 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.
