Nickle iron batteries

Re: Nickle iron batteries

Don't know if they are made anymore .. unless China?

Re: Nickle iron batteries

7 Month update.

This last week, was refill time. Becasue of the need to exclude Co2 from the cells, the vent & fill hole, has a little check valve in it, and it was a real pain to bypass it and refill. Cells were not quite yet down to the FILL---- indicator line, but each took about 1/2 gallon of distilled, to top them off. Bank seemed fine, but not under any heavy load yet. I've set the absorb time back again, to reduce gassing, we'll see how it goes.

Their size is roughly a bit larger than L-16's

House permit is imminent, and in 6 months, I hope to be living off the batteries at night.

Changhong Drops the Dime on Chinese Nickel Iron (Ni-Fe) Batteries.

'Changhong NF-S Series Nickel-Iron batteries

for solar PV application.'

From Oct. 2010


1.6.7 Cycling

The Changhong NF-S series NiFe

cell is adaptable to a wide range

of depth of discharge (DOD). The

number of cycles vary with DOD

required. The lower DOD is, the

more number of cycles are. The

number of cycles reach thousands

during shallow discharge, while it

can only reach hundreds of cycles

during deep discharge. The

following figure gives the effect of

DOD on the available cycle life.

NOTE: Changhong closed their website down for a while and when they came back
there were 2 versions of the Ni-Fe Solar Brochure if you poke around.

http://www.changhongbatteries.com/

Under Nickle-Iron (Ni-Fe)

it's called "Solar Ni-Fe cell catalogue"

Under Ni-Fe Battery for Solar & wind appliances

they are calling it

"Solar PV Ni-Fe cell catalogue"

IF you have an interest make a copy NOW. Funny things can happen with Changhong Literature.

(Back to the post.)


NOTE: With once Daily Cycling (See Chart)

__________________________________________


100% DOD = Well Under 3 Years

80% DOD = Around 3.3 Years

50% DOD = Around 8.6 Years

30% DOD = Around 16.8 Years

20% DOD = Around 23 Years

'Jan. 2008 Changhong NiFe Operators Manual'

1.4

Life time: The charge and discharge cycles should

be more than 750 times. During the life time, the

average discharge capacity should not be less

than nominal capacity. The minimum discharge

capacity should be more than 90% of the nominal

capacity.


NOTE: < snip >

"More than 750 Times"

This is the only Cycles Claim in this Operators Manual.

However note the HIGH Capacity Claim with the NEW jacked up
LiOH.H20 Levels. UP by 400% now.

This seems to be the first time in Internet History that this Important Data has
ever been pointed out.

There are plenty of Great Things about the NiFe cells that need
to be looked at properly and appreciated.

Absolutely no need for lies, half truths, myths or fish wives tales.

'Changhong Operators Manual'

NOTE: Prior to Jan. 2008

with 75% Lower LiOH.H2O Levels at typical USA Temperatures
than after the
Jan. 2008 Operators Manual above.


4.8 Lifetime

Life time: The number of full charge and full discharge cycles will

be about 1000 times depending on proper maintenance

> > > > including electrolyte replacement when needed. < < < <

Much longer lifespans can be expected if regular discharges are

less than 20%

where the number of charge / discharge cycles will be between

> > > > 5000 to 8000 cycles. < < < <

The end of the lifespan is defined by operation at 70% capacity
or lower

> > > > after replacing the electrolyte. < < < <

In many applications the battery will still be very useful for
many years or decades beyond this.



NOTE: "In many applications" can mean many things including

Capacity of Less than 70% being acceptable.

huh? why is 15% off of 40 grand such a bargain for a 1000ah 48v bank?

A pair of crown industrial 1000AH 24V can be had from our sponsor for under $10,000.

and you need 2 of them, for 48V.

so $20K for lead acid, or $34.3K for sexy Ni-Fe ?? The $15K difference could buy 3/4 a replacement bank of lead acid

Mike, It looks like under 10 grand for 1,000 Ah, 48 Volts at the Legendary Wind-Sun.com

The NF800-S Ni-Fe cells that I've been looking into NOW take in the low Thousands of Dollar$ to replace the Electrolyte - each time $

So you really need to narrow down how many go-go juice (electrolyte) changes (Over Time) to do a proper cost comparison - over time.

Also to compare 'Battery Capacity Over Time' which I suspect the Ni-Fe cells excel at. For goodness sakes they need to win at something :-)

The only way to REALLY find out for sure is to wear out two sets of batteries under identical loads and circumstances. Then measure what happens.

If I win the Mega Millions (or whatever) that battery test feat goes on my To Do List right away.

The Russian's wrote back to me and said they want to get into the USA Battery market real, real bad with their Ni-Fe batteries.

Asked them if they are willing to wear some stuff out doing ACTUAL no jive head to head battery comparisons (like it's a real business).

Gave John D'Angelo all the Russian contact info a couple of days ago. It's a love/ hate research relationship. What can I say ;-)

Of coarse you have to also Drop a nice Dime on somebody once in a while :-)

Update on my bank  (800ah 48V NiFe)  Aug 2018
//////

Iron should not costs multiples more than lead. Attributing this to lack of competition and high shipping fees associated with comparatively low volume. The earth has a lot of iron, the iron core takes up perhaps 25%, or more, of the earths volume. Iron is also more environmentally friendly to be sure. 

To be fair, the iron batteries that I viewed appeared to employ high quality construction standards. 

With cheap panels, iron batteries make good sense if they are reasonably priced. They are not very reasonably priced considering the cost of raw iron vs. raw lead. I have no idea why iron batteries are only made in China at this time. 

Lithium is currently both cheaper and far more efficient in charging. Not to mention very lightweight. 

"10 year old batteries" may not be a good source for comparison. 

AND NiCd use the same electrolyte as NiFe,  KOH. My NiCd's are all over 25 yrs old and using the same electrolyte, well maintained... Contamination in NiCd is the killer. A very small amount of oil is used to help prevent degradation of the electrolyte....NiCd and NiFe both can be refilled to recover their capacity....
