    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

    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.

    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

    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.

    Yes, I'm aware of that. I was referencing the possible similarities of marketing techniques that create an aura around a fallacy to give the impression of a reality that does not quite exist.

    ?? Tesla doesn't sell NiFe.

    The new sales are likely going to Iron Edison, a vendor who sells and integrates both LiFePO4 and NiFe storage systems.

    But, stay tuned. I shall be glad to relate both good and bad I find with the NiFes once I get them and am using them.
    If you need high quality deep cycle batteries, take a look at NiFe batteries.

    They are a very niche application. They are less efficient than LA. Need special voltage setup in charge controllers & inverter setpoints.
    They consume a lot of water, I use about 6-10 gall monthly, doing about 1/3 of the bank at a time. They need a messy electrolyte change out every 5-10 years
    They survive long cloud events when you have days of no hope for solar charging, and can't complete absorbcloudy days Jan2017.png

    And the week before

    So, to keep from flattening a LA bank, you'd need to run a generator a couple long days to complete a cycle, or risk sulfating LA batteries. Me, I just run enough (about 2 hrs day) to keep the power flowing till the next day
    Li batteries (LFP, LiPo4) Look hopeful, but have not had a lot of consumer history, and have some thermal concerns when chargeing in the cold

    Stay away from them.

    Search the forum for posts by Mike90250 and the keyword NiFe over the last couple of years.
