Rodney -> RE: How to cycle a 1.2V NiCd....... (5/8/2004 5:41:50 PM)

A no brainer, for a single cell you can pull it to absolute zero volts with no damage occuring as long as you did not draw so high a current that you caused excessive self heating internally. Just connect a 2.2 ohm resistor accross the terminals and leave it there for awhile, a couple of hours ought to do it. A better question is why would you want to do this? The chances of a single cell ever exhibiting what some would like to call memory (technically no such thing) is just about 1 in ten million or less. If you measure the ampere hours out though, it will give you a good indication of the health of the cell, all NiCads will wear out usually indicated by it ability to provide the required currentfor the required time. The typical life of a NiCad is 1000 charge/discharge cycles, roughly twice as good as NiMh. When the cell will only supply about 80% of its rated milliampere hours, it is time for replacement.
