Edison Battery

Edison Battery

Edison Battery

(OP)
I read that Edison had a Iron Nickel battery that so rarely needed replacement, the plant went out of business.

Also stories about people finding long abandoned tractors in the woods with a still good battery.

Can any one confirm this?

Do they have any extraordinary performance characteristics?


RE: Edison Battery

(OP)
Thanks IR, I should have checked myself.

That Wilkipedia link to modern NiFe battery data makes the same claims too!

Sure is expensive though.

RE: Edison Battery

Um, that must be a differtent article to the one I read. It said that the self discharge rate is a big problem, so no tractors in the woods.

RE: Edison Battery

Depends on the definition of "still good."  

Based on the Wikipedia article, one could envision that the battery could be topped off, recharged, and back in service, while a lead-acid battery would be permanently damaged.

RE: Edison Battery

Fair enough, that's a reasonable interpretation.

RE: Edison Battery

I just checked today, there are 4 high lift fork trucks using Edison Batteries still in use. These trucks went in to service in the early 60's based on the inspection records. They will sit idle for long periods and require a top off charge unless they are at the charging station.

At one time we had over 70, now about 30, electric fork trucks using Edison Batteries but all have been converted to lead/acid or something.

I was referring to the BeUtilityFree brochure.  There is a link at the bottom of the Wilki page.
