My understanding is that computer grade capacitors have higher leakage currents than similar sized non-computer grade capacitors. When reforming capacitors watch the current going into the capacitor. The forming process causes outgassing. If you excess the amount that the burst seal can handle, even after reforming, the capacitor will have limited life.
Never completely flatten a NICAD pack. Doing so will cause back charging the will put the wrong gasses on the wrong ends of the cell. The depolarizers will not absorb the gas and the pressure will increase in the cell and burst the burst seal. Again, like the electrolytic that was formed too fast, the cell will dry out over a month or so and you'll have a worthless battery pack. NiCads are best stored discharged. That means bring each cell to 1 volt. This is hard to measure in a battery pack. Dwight
