There's the crucial part where you are wrong, every Complete discharge takes "1 life cycle" out of the battery and the problem is with NiCds, you don't know with a VOM how "dead" or discharged the battery is. Some electronic gadgets have a "time to recharge" feature, things like an electric knife don't. So you kill the batteries each time a little more when in actual fact a deep discharge may only be needed maybe 1 in every 10 cycles. I used NiCds over the years with model flying, you learn really really quickly how to screw things up at your own expense.
Present day you will find more and more NiMH rechargables, they don't develop memory and don't use Cadmium (bad heavy metal).
