Whoops, yup, sorry, thinking of reconditioning NiCd packs once the memory effect cripples them. Discharging at 30A and charging at 1C, cycle that a few times and you can restore even decade old NiCd's crippled by the memory effect (crystallization of chemicals in the cells I believe.) Grabbed my dads old 12V cordless drill he was tossing and reconditioned the batteries this way and shes serving me well now.
Actually I usually discharge at 1.5-2C but that was when I actually used NiCd packs, now I'm all NiMh so it doesn't matter.
