Edison Battery?

Not to be cynical (what, me?) but I was wondering why the Edison
Battery was not being mentioned a lot more.
Did some research, found that the early electric vehicles may well
have many of the same batteries they started out with (Jay Leno
collection?). They were Nickel Iron, used a caustic solution as the
electrolyte, had pretty good current density, and were being used for
locomotives mainly. But their liability is that they could well easily
last for over 40 years, even with overcharging. Seems perfect for
a photovoltaic setup, wind generator, or both.
So the Exide folks bought up the company making them in 1972, stopped
production in 1975. In a very good marketing decision. They are the
second-largest lead acid battery company, and where's the sense of
turning out a product for which there's very little repeat market? In
direct competition with batteries that are good for maybe eight years?

Just mentioning in case anyone had some interest in looking further.

Take a look here for a discussion of the pros and cons.

The Battery Builder's Guide

It's a pretty good read and according to the author, as far as lead
acid batteries for a RE system goes, there are really only two types:
1) Faure (pasted lead) plates, like is used in T105 or L16 batteries.
2) Plante (pure lead) plates, like used in industrial, Surrette, or
HUP batteries.

Basically, the more lead, the better the battery.

NiFe cells from China:

Look at 7008; $010 for 12V 122AH. Batteries Plus sells a 12V 105AH
deep discharge for $5. If it lasts only 5 years you break even at 60

Interesting!  But not tempting.  Look close at the graphs.  Except perhaps here
in Florida, you would need to keep them in a heated room.  Also, they have high
self-discharge compard to a lead-acid.  That  represents a considerable 24/7
vampire load on your system.

Yep, I'll just stick to my 6-volt lead-acid batteries.  When I got them they
were perhaps 5 yers old (standby service only), and .they still test fine after
another 5 years.
