Hi, some comments:
the original cells ( 1/3AA 14x17mm, cost in Germany about 2 Euro each ) have a capacity of 110 mAh. The POWER PACK M gives 25mA charge current. So the nominal charging time for a complete empty pack will be 110*1,4/25=6,16 = 6 hours 10 minutes. ( 1,4 is the typical effiency factor for NiCd charge calculation ) I would not recommend to use NiMh cells for such kind of charging ( user controlled by time ). They are much more sensitive for overcharging ! Each overcharging will reduce the capacity ! I putted those in a home cellular phone and the cells were dead after half of a year. The charging was very stupid: charging complete after putting the handset onto the base even if already fully charged. NiCd cells are here much more sturdy. regards Bernd H. > >The biggest issue with the NiCd packs is not overcharging (a full > >charge is 16 hours) > > Other post says 6 to 10 hours. 16 would be a max ? > > >but with having to wait until they are dead to recharge them, or > >rigging a device to discharge them before you charge them. > > Because of "memory building" ? > > >My best advice would be to buy the NiCd pack, use it w/o worrying > >about the NiCd battery life, and they when they die, replace the > >NiCd cells with NiMH cells. > > NiMH ??? > > Almost any battery shop can build or order the cell packs...I can > give you specs if you need them. > > James, I have 2 dead power packs and I want to have them "repacked". > Could you give me the specs ?
