If you are interestred in desulphation and battery rejuvination.
Hop onto google and punch in "battery desulphation"....or "battery Rejuvination"
There is a lot to read.
Chemical desulphation V electronic and combinations of both...and all sorts of pros and cons....and there are some cons.
To sumarise.
Sulphation is a very specific condition in batteries.....not all batteries fail due to sulphation..and if you have a far gone battery...there is probaly no help for it.
IF....the battery is suffering from desulphation.....it MAY..be possible to significantly improve its condition...but it is neither, quick, easy or a guaranted thing AND there are drawbacks.
Almost without exception, chemical desulphation will result in loss of capacity and loss of acid...AND complete failure is a reasonable posibility ......but it is reasonably fast.
There are a number of battery remidies...some are nothing but short term fixes that sign the batteries death warrant, some are marginally effective and some just do bugger all.
NOW...there have been changes in the chemistry of batteries, that have achieved significant improvements to battery life and performance......these mostly revolve arround addition of calciium or other metals to the plates and changing from simple hydrochloric acid..to something a little more colplex.
NOW..it may be that inox has some of those chemicals in it.....cant say for sure.
For chemical desulphation the chemical of the moment is "ethylene diamine tetra acetic acid"....all reports are that it is quite effectice...but has the issues mentioned above.
This acid is available, but it is expensive and a little hard to obtain as its self...there are a couple of vendors that supply a product bassed on it......but its hardly worth it unless you have large expensive batteries.
ONTO electronic desulphation.
I am currently doing some experinemts of my own ...and I do have instruments to measure performance....these experiments will take some time.
The problem is that this takes much longer than many want to believe and pretty high energy desulphators are required.
the people who are into this the most are the
home built electric vehicle people, the golf buggy enthusiats and the alternative energy enthusiasts.
It is worthwhile, because these people use very large expensive arrays of batteries and it is worth it for them to have a go.
If sucess is
forth comming it is reasonable to expect a T105, 225Ah trojan gof cart battery to take a month continuous on a high energy desulphator, to come from a recoverable state to as good as it will get functional state.
When you have a machine that takes between $1500 and $4500 worth of batteries and you have the time and space to reprocess scrounged batteries...it may be a viable thing.
For the rest of us with smallish relativly low cost batteries...its just not worth the bother.
We are better off buying a new good quality modern technology battery and looking after it.
AND...a properly recoveered & reconditioned battery that was a good prospect will never perform as
well as a new battery of the same sort.....AND the desulphation may only extend the battery live of 5 years typical out another 2 years tops.
Serioulsy... go buy a new battery and don't be a cheap scate...but a good one.
cheers

Just a bit of a follow up.
The inox mx2, MSDS, lists Cadminum Sulphate as its only hazardous ingredient less than 5%
it mentions...ingredients not determined to be hazardous.
Water is certain and may be epsom salts....
This would make it a fairly old and pedestrian formulation.
There is a hell of a lot of reading on the net about these sorts of processes.
just for interest this...
http://homepages.ihug.co.nz/~pcaffell/Battery_Maintanence_Tips.pdf.
gives a pretty light over view...it does not discuss the pros and cons much.
As I have mentioned....many of these things "work".
Epsom salts, definitely works( like some other chemical means)...it is not fast and there is loss of reactive material.... the suphate is to my understanding not converted back into active material...thus the loss of capacity.
Electronic desulphation breaks up the resistant sulphates and returns them to active material.
Sulphates are a normal part of lead acid battery operation, but "sulphation" is sulphates that become resistant to the normal chemical cycle.
