I am looking for information about fast charging NiCad batteries.
I understand it is possible to recharge NiCads in 15 minutes to 1 hour,
if certain precautions are taken to avoid overcharging and overheating.
My questions are:
	1) how much current should be used to fast charge? (10 times the
	   16 hous rate, or what??)
	2) how is the charging time determined?? (strictly on a time basis?
	   by measuring the terminal voltage with a constant current source?)
	3) is a constant current source used for the charger? ( or constant
	   voltage, or some combination?)
What questions should I have asked that I didn't??

Thanks for any help.
