Since your NiMH's are transmitter and receiver packs, and not run packs, I would charge them at anywhere form 0.5C to 1C. I wouldn't go anywhere above 1C at the most if you're desperate to have them charged. You're going for capacity not punch. The glow driver can also be charged at 1C, but if you want to cycle it than C/10 is the best for NiCds. For the delta peak setting (mv) I would 5 mv per cell on the NiMH, and 7-10 per cell for a NiCd. I would then check the charge capacity compared to the rated capacity of the battery, also take into consideration the temperature of the battery. If the charge capacity is considerably lower than the rated capacity, then you can raise the mv setting a little. For the cut off on these I would use anywhere form 0.9 to 1.1 volts per cell.
For the gel cell I would use anywhere from 0.7 to 1.4 amps to charge. Again, I would only use the higher charge rate if I was desperate to have it charged. For some reason my engineer considered 1 cell equal to 6 volts. So for a 12 volt gel cell set it for 2 cells. You really shouldn't have to cycle a gel cell. Once it's dead, it's dead.
