    Somehow this seems to have gotten off the rails.

    My comments to KIRK1's comment was meant to suggest that if he believes "there's right now a host of Fe-Ni vendors in china so somebody must be buying Fe-Ni batteries" (according to who, BTW ?) he may be a victim of the same type of marketing hype that Musk tries to pull off with is production capability fantasies and projections. That is, China MAY have all sorts of production capacity, but China MAY also (or rather) have a goal of making folks think they have all sorts of production capacity that they in fact do not have, and/or/also that would like folks to think sales are greater than actual for reasons of their own. Or, there may indeed be a boatload of vendors who aren't producing as much or as profitably as they'd like everyone to think.

    Then too, the idea that there's a lot of Fe-Ni Chinese batteries sold seems to be an statement that could use some verification and context.

    • Well, I have a chicom set and bought it via BeUtilityFree.com I don't plan on buying another one. I think they have a lot of domestic use in China

        Is this because you are happy with them, or because you aren't happy with them?

          There's right now a host of Fe-Ni vendors in China: so somebody MUST be buying them.
          Then you must be a fool or Chi-Com? Edison never renewed his Patent and it expired in 1940's, Edison Electric sold the plant to Exide in in 1972, and production ceased in 1975.

          Due to its low specific energy, poor charge retention, poor charge/discharge efficiency, high maintenance, and high cost of manufacture, other types of rechargeable batteries have antiquated NiFe batteries.

          There only real application that can be justified is in Mining Industry for emergency lightning where batteries are exposed to high temps, heavy vibration. slow charge/discharge, efficiency and cost is of no concern.

            I'm happy enough, spent the $$$ already, and re-rejuvenated the electrolyte this last summer, still going and I never worry about sulfation destroying them in a week. But they are inefficient thirsty bastards
