well heres my experience.Been servicing #10 us hc250's which sat in a uncharged (drained state) for 6 months they would not hold a charge or even reach 12.5 v on a meter even after charging for two days.
  I figured by all the loud girgling of large amounts of large blurping bubbles they were shot.Some show signs of plate warping and creep. So I figured what the heck a little epsons salts could not make it worse then it was. One teaspoon of salt to one table spoon of distilled water for each of the 30 cells. Boiled the brew to melt the salt and added a table spoon of hot mix to each cell. Then back on the charger. Manually cycled the charger for two hours in high charge 4 hours in desulfate for 30 hours. It worked.
  I had plenty of time to think. I believe it is the O2 content which causes the sulfation. Boiling water removes O2 from removing micro air bubbles which are present. Ive heard of some people equalizing batteries by over charging causing them to boil and off gas which would be one way of getting extra air out of the electrolite but would be very stressful to the plates. I was also watching a food channel show about how to make clear ice cubes that night and they boiled distilled water twice letting it cool in between to remove the tiny air bubbles from the water which confirmed my earlier thoughts. If hydrogen floats up lighter then air then normal use would eventually remove hydrogen leaving more oxygen content which oxidizes the plates with a combination of sulfur and oxygen. The surface tension difference may cause that oxidation layer to prevent water from entering the plate surface. Better quality water with less O2 and heat may be the easy way to resolve it. I have 10 more batteries which are slated to be recycled which have been so completely destroyed the cases have swollen and become egg shaped.
  A thought, place the batteries in a boiling vat of water and charge alternating the charge cycle same as above but also removing all the acid and putting back only twice boiled and cooled new water. If the opportunity presents itself in terms of time I may even try to build a vacuum chamber or vacuum device to attach to the battery cells to remove O2 while charging and conditioning.
  In any event Im ahead 2 grand already.Being in command of 27,000 $ worth of batteries and growing I think a little investigation using junk batteries is not out of the question.
  As time and events permit I will update. Hopefully the distributor I buy from wont have a hissy fit and raise the battery prices and maybe there is way to find out if electroplating techniques use specific bath temperatures to improve the rate at which the process works for electroplating.

Thanks pese
   Ive seen that book before, nice easy circuit but my charger is a smart charger with a similar functioning pulser. I'm not that patient as to wait a couple months to reclaim a battery. If it turns out that the oxygen content in water/acid is the reason the eventual death of lead acid batteries then why use water at all? There must be other conductive liquids which do not contain oxygen that could be used as a replacement in lead acid batteries. Since the battery industry sells some billions of dollars worth of batteries each year i doubt they will be of much or any assistance in an effort to make even one battery last longer. That would be no more practical then the electric company helping to make energy free.
   If batteries are effected in their output by temperature then it should stand to reason it would also effect the charge side either by surface tension or emulsion of the acid.Again the use of water begins to look like the use of a known week point to regulate the life expectancy of the product.

use one two other batteries so you have also strong energy for short time to load unload  your "experimental /repairing" battery..
 
each "cell" of battery have 2volts (2.2 if loaded) . so you can also use fro two batteries 7 cells (14 volts) to unload in your
"repair-experimental cell. (even using the 24 volts to cahrge the 12volt, BUT give attention to the load resistors (lamps) and
stay at your work that the cahrging battery will nor exeed the 14,8 volts, because they will boile end spend a lot of
hydroxy gases that can expole (i seen this 2 times.  (If you will not build an watercar , like Dingle) give attention to that
for chargeing current limiting resistors , use OMLY car lamps.  (60 watt 12volt lamps take approx. 5 amp.) so unse
some in paralled toi cahard , and discharge the batteries.

Even ... very "week" batteries you will try to charge for dotzend seconds in revers mode (reverse polarity) it will helf that an normal charging can be started.

Pese

PS
This way you can use any small charger (but it need more time).

"Specialists" use als for "Elektrowelding" no "weldingtransformers" . 3 car bateries (36volts) ca be used for mor than 1 hour welding-time! So you need only an small transformer to load this, during  1 day

Riderino,
With all due respect to your work, Groundloop has also posted a very helpful schematic for the same purposes here:
http://www.overunity.com/index.php/topic,4057.msg75477.html#msg75477
The unit does work.

That said, your approach may be quite different but equally useful.  All the best to you in your endeavours.
B

i have put epson salts directly in each cell (no water) 1 month ago, 15 milimiters in all the 6 cells in one battery, no water, and it has work like Neptune said to us in an another topic

cheap, easy, no electronic pulsating device needed

i just do not know why this is not the perfect way, is there a problem with epson salts ? , someone said that it is damaging the battery...will it work for a long time ? i guess so

my old battery was dead, and did not keep a charge at all, 15 milimiters in each cell of the battery and be amaze, easy and cheap

if something go wrong i will report it here

I found this thread over on RC4 about conductive liquids, it's not much help but does offer some suggestions, information and reasoning.

Hi all,

Those who are not very good with electronic circuits can get a ready built desulfating chargers from Bedini research:

http://r-charge.com/

There is also this company that sells some units but I have no info about their quality:

http://www.tecmate.com/optimate3_detail.php

Take care,

Michel

not Bedini not Radiant.

This "words" are good to earn high prices.-

To find the same reuslts.
Its need only experience amd kmowledge that you find this way...

Nothing NEW
all WELLKNOW.

Find it out yourself
Lot of written knowledge to find in WEB

Hi all

Here is link to Bedini on batteries.  Very educational.  At about the half way point,  he shows about converting lead acid battery to alkaline battery using alum.

 http://video.google.com/videoplay?docid=-7091246195185928492&hl=en

Here is another link to convert to alkaline.  Read the notes at the bottom of the page.

@tishatang

many thanks for these 2 great links !

This seems really to be an alternative to change
the lead acid battery industry to be more "green".

Now this industry will probaby soon be called:

lead alum industry.

Has anybody tried to roll up
lead plates like John Bedini and built this way his homemade
lead alum batteries for solar charging or other storage needs ?

How good do these homemade batteries work on 12 volts to 120/240 Volts
inverters ?

Many thanks.

Regards, Stefan.

If it needs just to roll up 2 lead plates with some rubber spacers between it and
the just fill it up with a alum-destilled water mix,
how much Ampere-hours capacity will such a battery have,
that John Bedini built this way ?

So it seems, it depends only on the surface of the lead plates or foils.

So it seems you can build yourself really big batteries this way.

The question is, how long they will last and if they are able to be charged
also with  such a radiant energy charger or with the Bedini chargers.

Regards, Stefan.
