These are Sanyo NiCd 2400? If so, this is good news as they have sintered electrodes and are rather bullet proof. The cells will have totally discharged and the electrolyte settled out of the seperator during storage, so their internal resistance will be initially higher and you may get some premature negative delta V charge termination for the first few cycles (this is where the voltage of the cell rises during the first few minutes of charge and then drops, fooling your charger into thinking the cells are fully charged when they are not). Best thing to do is put them on a 1A charge and keep an eye on them. They should charge for around 2.5 hours but if they terminate charge early put them back on charge again, it is ok to keep doing this unless they get warm (>45C). Once charged, discharge them to 1.0V/cell and repeat the process (charge and discharge). When full discharged, leave them for a few days, then come back and measure their voltage. Good cells will spring back up and still be >1.15V. If any have internal shorts then they will drop off rapidly.
Hope this helps.
