Sanyo claim to have solved the self-discharge problem - . That's just a shiny marketing site, from memory they state the batteries arrive charged, and will discharge to 85% in one year. Not bad. I came across these about a year ago; I haven't tried them, nor have I heard anything about them. I'm not sure what their market actually is, for stuff you only use occasionally alkaline (or even lithium) would work out better & cheaper. A better backup battery? Camera flashes?
