]What *he* said. I believe the target voltage for discharging is .9 to 1.0
]volts per cell. Find the number of cells in any NiCd battery by dividing
]by the NiCd cell voltage, 1.2. You don't want to go lower than 5.4 (better
]luck next time :-).
Better yet, don't discharge it at all. The most recent Gates application
notes show that there is NO appreciable memory effect in modern NiCads -
they ran a lot of experiments. Thus, there is NO REASON TO DISCHARGE NICADS!
