Hi Dale,
I agree, I certainly don't do it that way.? But some sales material for "smart chargers" describe this method.? I just use a power supply regulated to not exceed 1.35 or 1.4V per cell and a current limit at about C/10 or C/5.? I include a small resistor between the supply and the battery so that it doesn't apply full current all the way to the end voltage. This doesn't give the fastest charge, but it works and avoids battery damage.
Cheers,
Halden
