Hello, Do you know how to date Edison Nickel - Iron Metal cased 1.2 volt cells. I think mm means 1943. There is a date code out there somewhere. I have 22 of these and would like to recondition them. Can you help?

Thanks Randy

I read the entire thread and I'm surprised no one has mentioned this......

Get several people together and do a "group buy" from a Chinese or Russian manufacturer. An import specialist would be needed, but the minor cost would be spread over several people and a large order would no doubt mean a discount. You might even consider a "group bank loan" and then each person pay his share of the payments. Yeah, it could get confusing so someone would have to be in charge of handling the finances.....but it could work.

Once they're delivered stateside (probably a Pacific port) it would be the responsibility of the buyers to pick them up. Okay, some would have to drive a long ways for their prize, but it would be a once in a lifetime purchase, right? It would be worth it.

Yes, you need more Edison cells than lead acid for a given voltage, but to me the positives far outweigh the negatives (no pun intended). I'd love to have a set......even small ones.........for my Delco Light plants.

I just could not justify buying Edison Nickel Iron over Edison Lithium Iron. I've heard people say that the lifespan of LiFePO4s is often understated, that they are 15 year cells. Way lighter, no maintenance, and with 80% discharge and max efficiency you need less amp hours than Nickel Iron. Or maybe I was just brainwashed by these videos...

If there are flaws in the videos please point them out to me, I'm not looking to win an argument with anyone about battery types, I'm just trying to get beyond misinformation, I'm a novice myself who has eye'd up Edison's LiFePO4 as well as NiFe solar off grid packages. Then I saw these vids recently and don't know what to think.

I'm no expert on stationary cells by any stretch of the imagination.
But I have a friend who owns (just retired) a fairly large company that does a lot of business in motive and backup battery systems, around $20 million per year.

Bottom line is this.
All the Chin manufacturers be it Lipo, Edison alkalines, and lead acid cells are providing crap quality. The cases leak and crack, the case to lid seal leaks and the posts leak. Their power ratings are over stated and often provide 1/3 of what is published. The life is also often 50% of what is stated. So be wary of you intend to buy one of these installations.

The best bang for the buck is still flooded lead acid which has a high power density and is still the cheapest. He says eventually the lithiums or NiMh with ultra capacitors will be improved and some day eclipse lead acid. Maybe in 10-15 years.

The chins have no interest in improving the quality as they know they're the cheapest game in town. So if you're looking for a battery bank, go for big lead acid cells with a lot of acid capacity. Big, bulky, stinky and heavy but still your best bet.

Do you, or anyone know where the best bang for your buck is for high quality LiFePO4s? For starters I just want a nice LiFePO4 to simply keep charged from my wall outlet in order to have some small basic stuff if I lose power. Maybe I'll add on to it later but that's all I want right now.

I don't know if they are the best bang for buck, but I have gotten nothing but quality cells from all-battery.com. Ni-cad cells I bought from them about four years ago are still going strong.

Ten years ago I bought decent cells in 100 lots from an operation in Korea. I don't recall the vendor now. These were 4" wide, 1.5" thick and about 7" tall.
*Note that these are individual cells and you MUST install monitoring circuitry to each cell to prevent runaway that will be like a mini Fukushima.

Just start googling for the capacity you need.
