I want to buy a digital camera that uses rechargeable and disposable AA alkaline batteries. I don't know if I want ni-cd or ni-mh (or what it means) The difference is the chemical make-up of the two batteries you listed. The Nickle cadium batteries are the first to hit mainstream. They have problems in developing a memory so to speak. I do not recommend Nickle Cadium batteries. The Nickle Metal Hydride batteries came out in replacement of the old problematic Nickle Cadium batteries. The Nickle Metal Hydride batteries do not suffer from charge memory. The Nickle Cadium batteries, say, if you recharged them before they where depleted all the way would develop a memory at that voltage level. Even though you still had a good charge left, the battery would say it was dead. One other thing to remember is that the Ni-Cd battery normally only shows a 1.2 volt charge when completely charged, most new digital cameras will not work at that voltage level. Get yourself some good Nickle Metal Hydride batteries and an intelligent charger, you'll never look back. Good Luck and happy shooting. NiMh do not have memory problems (as the previous poster indicated), and they are really inexpensive. I got recently 2 4-packs of Sanyo 2500 mAh batteries here: http://thomas-distributing.com/sanyo-250... . NO problems with theorder, and fast shipping (and no, I DON"T work for them ;) ).
Cheers,
