Interstate deep cycle

[bagpiperjosh]

can anyone tell me which interstate batteries are good deep cycle batteries? if so can you give part numbers?

thanks

That is easy to answer. Interstate does not make True Deep Cycle Batteries.

Close as they get is a hybrid battery aka Marine, RV, and Golf Cart batteries. Hope that helps. FWIW they only make 1 Golf Cart battery on the bottom of the page GC2 BCI series.

i get a really good discount for interstate through my work, so naturally that would be the case

A good discount for a battery that will last you 5 years, is better than list price for a 10 year battery, except for the day of labor to change them out

Mike an Interstate hybrid will only last 2 years at best pressed into deep cycle service. Long term I think it is best to look into $/wh vs service life. Sure you can buy a discount battery @ $90/Kwh that last 2 or 3 years with TLC, vs a model that cost $150/wh that last 5 to 7 years with a 10 year warranty. Both batteries will cost more when replacement is required. The 10 year battery is pro-rated, the discount battery is eat it.

What did you spend on NiFe per Kwh?

Sunking,

The last cheap 'Marine Batteries' that I bought at Walmart were around $60 per kWh. Everstart MAXX
batteries with an 18 Month Free replacement warranty. In my case it's no questions asked because I'm in
there every week and know the guys. The thing is in a lot of years now they always make it at least
a couple of years using them perhaps 75 (or so) times per year taking them down to 50% - 60% SOC.
At 3 years old they seem to hold around 1/2 what they did when newer. Before 4 years they are gone.

For a situation in the back of a truck where they could walk I like them just fine.
I don't want them inside the truck like a high dollar Odyssey (AKA DieHard) battery for special occasions
like a portable winch - that can really suck the juice.

I use Timers with Any maintenance Battery Charger no matter who makes it.
If it doesn't work coming on and off without manually resetting the charger - I don't need it.

I'm glad to see your the 'Top Dog' with Posts now!! From here on out it's 'The Legendary' Sunking

Too much. But I hope I only have to change electrolyte once 850ah @ 52V

What is the cost and time involved to change electrolyte? Any Employment Prevention Agency issues to deal with? I know lye is really toxic stuff.

[Sunking]

Too much.

Let me Guess. $.40 to $.60 WH. If so did you consider LFP over NiFe? I can modify a Midnight Solar controller for LFP pretty cheaply.

Nickel Iron Battery Electrolyte and the hard Ni-Fe Reality

Too much. But I hope I only have to change electrolyte once 850ah @ 52V

Certainly Edison or the Edison Storage Battery Company never Lied to people that it was a good idea to
'stretch' the Nickel-Iron battery electrolyte replacement intervals. It will destroy your expensive Ni-Fe cells -
plain and simple. Nor did Changhong Batteries who supplies your Ni-Fe Cells to
Beutilityfree and Iron Edison ever talk any foolish nonsense about waiting too long - that I ever saw.

There are other Electrolyte 'Contaminants' that Edison was writing about when he unveiled his new
Ni-Fe Battery reconditioning process in 1904. The "E" Cells had only been on the market since 1903.

Edison was already concerned with bringing his Ni-Fe cells back from the dead because of
Poisoning of the Nickel Matrix in the Positive Elements.

By 1907 Mr. Edison identified and moved 'Iron Poisoning' to the top of his List of
Ni-Fe electrolyte contaminants that is a much longer list
than your average person realizes.
The carbonates may be playing a second fiddle to bigger problems.

Almost 20 years later in the 1920's Edison was still coming up with more contamination Bad News
and more NEW methods to fight the destruction of his Ni-Fe batteries.

Amazingly the Ni-Fe subject has been kept wrapped in a shroud of ignorance and Lies for over 100 years now.

The Edison Storage Battery Company recommended changing the Ni-Fe Auto Battery Electrolyte every
8 to 10 months and the Ni-Fe Storage Battery Electrolyte every 3 to 6 years.
In writing. Can I get a witness?

You have been a victim of Ni-Fe Sales Propaganda that was planted many years ago . There was a guy
pushing Chinese Ni-Fe Cells in America long before Diamond John at Beutilityfree was ever thought of.

All this change the Nickel-Iron-Battery Electrolyte every 7 to 10 years or every 20 years is a big Lie.

Quote from the Changhong Batteries Ni-Fe Operators Manual:

3.3.3 The electrolyte will absorb the carbon dioxide in
the air and create carbonate easily during
operation. When carbonate in the electrolyte is
over 50g/L, the performance of the battery
will be badly effected.

After charge and discharge for 150~200 cycles or operate for
1 year, please check the carbonate in the electrolyte. If the carbonate in the
electrolyte is over 50g/L, please replace the electrolyte.

(Changhong is watching a few of the US Forums and hopefully they will tighten things up
to deal with the planted stories and other issues being brought to their attention).
