I've no idea what the so-called "C-rate" is...

You need to know this!

C is the cell's capacity in mAh. This is usually right there on the cell.
For example, I have some decade-old Panasonic nicads marked 500mAh. (That's
not very high capacity, compared to recent cells.)

If you charged the cell at 50mA, that would be a 0.1C charge rate.

Indeed, yes... a bit arcane!
Typical NiMH's today (2008) are 2100 mAH so "0.1C" would be 210 mA.
I should check my Sanyo charger - my guess is that it exceeds "0.5C",
i.e. an amp, or so.
Still looking for a Maha/Powerex MH-C9000 charger.
