    I hear that in Japan there is a Lithium Ion battery that does not discharge (at
    least it takes many years). How is this possible, and is this even possible?
    I read about this battery on the web somewhere, but cannot cite the source at
    this time.

    Sure, it weighs about 400 pounds, and outputs 3V at 1 amp max.
    Cost? well as a one of a kind, priceless!

    Lithium-manganese cells have a very low self discharge rate of <2%/yr.
    Guaranteed shelf life of 10yrs. But it depends on storage temperatures.
    They are good for life-jackets and the like.
    If you separate the electrolyte you could activate the cells only in an
    emergency event. Zinc-oxide cells come to mind.

    Aren't you talking shelf life?
