   Going off-grid or replacing a set of old lead-acid batteries? The Iron Edison Nickel Iron (NiFe) battery will be the last battery you will ever buy. No battery offers a better long-term value for renewable energy storage. Have questions or need help designing your system? Give us a call (720-432-6433)

     What is the efficiency of the NiFe battery on charge/discharge cycle?

   Hi,

   My other half is interested in all this alternative energy stuff, and I told him about your site,
   does your neighbour still has second hand batteries available ?

   Do you know if this is a one-time ‘call now to avoid disappointment’ type of situation, or does your neighbour have a steady supply of these second-hand batteries?

   Those NiFe batteries look pretty interesting, it’s just sad that an industry to supply them is so dead compared to lead-acid.

   I guess that the up-front expense is one factor. Also, Excide bought the only surviving Ni-Fe manufacturer in the US, in the ’70s and shut it down shortly thereafter. Ni-Fe has virtually disappeared from our vocabulary but that’s no reflection on their quality.

   Just wondering, Hugh, whether anyone you know has tried Nickle-Iron batteries. I’ve just written an article about batteries and these look pretty good. They’ve certainly been proven and the engineering reports corroborate the anecdotal evidence. They may be a bit less efficient than lead-acid but they tolerate abuse that would kill lead-acid batteries. After a good ten years of service, the electrolyte can be changed and the batteries will perform as well as they did when new.
   Here’s a good site linked to some good engineering studies and to the Chinese source.

   I interviewed this guy and he’s a very enthusiastic Ni-Fe user, himself.

     I tried nickel-cadmium a long time ago in the days when we used 12-volt light bulbs. My problem was with the range of voltage between charge and discharge. Bulbs blew on charge, and the light was very dim on discharge. I don’t know if nickel-iron has this problem. It’s not such an issue with modern sine-wave inverters but it still reflects a low efficiency.

     Since then I have not used them although I have been involved with installations that used secondhand ones. By the way, the Northern Lighthouse Board are disposing of quite a few as they replace old diesel systems in their lighthouses around Scotland. Or this program may now be finished. Ni-Cd is a more toxic technology than Lead-acid, so these batteries may be expensive to dispose of.

     I wonder why Ni-Fe batteries are not more widely used?
