1.  Whats the difference between NiCd and NiMh?

Nickel metal hydride (NiMH) advantages:                         Nickel cadmium (NiCad) advantages:
** lighter than NiCad                                                         ** Longer Life Cycles
** 2-3X capacity to equal size NiCad                                ** Performs in cold tempertures (good performance down to 20 F)
                                                                                            ** Lower self-discharge level than NiMh
                                                                                            ** No voltage drop at/near discharge level
​                                                                                            ** Less expensive

Nickel metal hydride (NiMH) disadvantages:                   Nickle Cadmium (NiCad) disadvantages:
** fewer life cycles compared to NiCad                         ** Heavy
** shorter run time                                                          ** May suffer from "Memory Effect" if                                                                                                constantly discharged  half-way and then recharged
** performs the worst in cold temperatures
** higher self-discharge level than NiCad
** voltage drop at near-discharged levels
** More expensive
