Letter Re: AA Cells and Mobile Power
There was a discussion about batteries a few days back on SurvivalBlog. The writer advocated using AA NiMH cells almost exclusively, with adapters for devices requiring C and D cells. While I do agree that this is a good approach for some devices, there is certainly some merit to having full size 10 Amp Hour (10,000 MAH) batteries in high [current] draw or long term use devices. Not only is capacity significantly higher on larger cells, but the maximum safe current draw is higher too. Good NiMH C cells have 2-to-3 times the capacity of AA cells, and NiMH D …
