Hi aeajr,
The problem with deep discharging a Ni-Cd "battery" is that it can result in cell reversal, that's why proper cyclers, like the current Triton and and way back to the old Digipace cut off at about .9V per cell. A single cell can be safely discharged totally, you can put an old glow plug in your Ni-starter and leave it on the bench overnight and not damage the cell (just don't stand it next to a pile of oily rags[X(]). NiCads from way back, like the late 60's probably were prone to "memory", of course back when I was a kid you were told you would get a cramp and drown if you went in the water in less than an hour after eating

In an earlier post Matt Kirsch addressed the issue of the C designation in battery packs, and he was quite right in his response. The only reason I mention it weeks later is that just for grins, check page 9 of the current Tower Talk and see how the copy writers messed up on that one, a 1500mah 3S 8 cell Li-Po, I think not
