You have important differences between Edison Nickel-Iron Batteries and Chinese Ni-Fe.
Some obvious and some that are not so noticeable.
All of them seem to be very important. One change is that the Edison Cell - Positive and Negative Plates
were kept fastened together with a hardware system where the Negative and Positive Elements
could be separated for 'secret Ni-Fe service' if need be.
This is where your old timer accounts about cleaning the plates and if necessary even
reconditioning the Positive 'Nickel Matrix Material' located in the pockets of the
positive plates comes to play.
One expert that helped me calls it 'A Lost Art' that he learned in his youth and then forgot over
many decades of a long life. Nothing got Lost. Not a bit of it.
Why it took just a hobbyist (myself) that got hooked on debunking all the mystery, myths, fish wives tales,
jive and riddles about Ni-Fe - to re-discover what is really going on is beyond me. It wasn't quick and it
wasn't exactly an easy puzzle but it was a lot of fun.
Keep Iron Poisoning in your mind from here on out.
Notice I didn't say maybe, please, perhaps, (or so) or whatever - but just laid it out there raw and cool.
Today the Chinese Ni-Fe Plates are welded to a current carrying bar so if you contaminate the
positive elements which is the Nickel Hydroxide (+ additives ?) (another post), your in big trouble
and your just out.
If it doesn't all rinse out with flushing (which I Highly doubt) then it's tough and you permanently lose capacity.
When it gets bad enough you have throwaways on your hands with a 20% Nickel content.
(See the Changhong Batteries MSDS). A major battery junk dealer on ebay
pays around 15 cents per pound for old Ni-Fe batteries. He's paying around 43 cents for common Lead Acid
batteries because though lead is cheaper it's in a much higher battery concentration.
Another major difference was going from the full metal cases (jars) to much more fragile
plastic cases. I feel that this may have been a huge mistake and may have a
major influence on the 'touchy' Ni-Fe Electrolyte. (another post) If you read the catalog called
'Changhong NF-S Series Nickel-Iron batteries for solar PV Application'
they tell you to Look for around 3 years (or so) of total use at 80% DOD which is Much lower than what
the Rolls 5000 Series batteries have in them.
I believe the Rolls 5000 series looks like they have around 82% MORE Life Cycles at 80% DOD than
the Changhong Ni-Fe cells do. Around 58% more Cycles at 100% DOD.
The Changhong cells start to show an advantage over the Rolls once you get up to
a MUCH More Reasonable DOD. At 50% DOD (50% Dead) the 2 battery technologies are fairly even.
There are situations where a person may need to 'buy a good 5 to 7 years with an undersized, overworked,
battery bank. In that case it's best to call Northern Arizona Wind & Sun.
Ni-Fe is for when you really have it ALL together, have plenty95 of cash and Really know Exactly what
to expect. Or at least hope that you do.
Plus we start buying the Ni-Fe cells directly from China someday unless a Reliable, honest player wants to
step up to the plate after
'The Ni-Fe Theory of Battery-tivity' has been revealed.
The Chinese Ni-Fe Cells Shine at 20% DOD with the life Cycle Chart jumping up
to over 23 years of good use.
You have an American Changhong reseller, Brandon Williams at Iron Edison Batteries advertising
that you can run the new Ni-Fe Batteries into the ground at 85% DOD
(85% Dead) on a daily basis.
This will Destroy the expensive Ni-Fe Cells much Sooner rather than later. When you see a
Changhong Operators Manual (which the resellers have always withheld from you) (another post)
it gets explained to you that the Life Cycles stated are WITH Expensive Electrolyte changes included.
Changhong and the Electric Indian does Not need to operate a Lying dreamland.
They have a Lot of different products in over 100 Countries. Lot's of different battery chemistries as well.
So changing the Electrolyte at 7-10 years is a real joke if you even slightly abused the new Ni-Fe Cells.
The batteries were totally shot before that - even at 60% DOD each day.
Let along running them 85% dead every day like somebodies fool. Only because much of the manufacturer's
data had been kept from you or what was available went unnoticed.
A NEW Look at old Charging routine's may be needed for Longer electrolyte life and less problems in general.
Now more than ever the name of the game is to avoid Positive Element Contamination from The Very
Beginning. It's NOT just Carbonates that you have to worry about.
According to certified research notes from Thomas A. Edison the Ni-Fe Cells (in time) are fully capable of
Self Destruction - all by themselves. Iron Poisoning of the Positive Electrodes. (another post)
The Carbonates and OTHER Contaminates is nothing but window dressing to the badboys in comparison.
(Lord willing, to be continued.)
