Title: old free batteries drive pickup truck, new battery reviving technology !
Post by: hartiberlin on January 13, 2008, 09:43:14 PM
Have a look at this info:

and

I wonder, if they also use some kind
of High voltage BackEMF pulse system onboard to
recharge the batteries on the fly...

I discovered a cheap and cheerful way to revive lead acid batteries years ago when I was into electric tricycles. It does not work with sealed batteries. First, do a discharge test to determine ampere-hour capacity, at say,4 amps. Now add 10 millilitres of Epsom salts to each cell, and charge battery. repeat discharge test. my experience is that after 3 or 4 charge- discharge cycles, capacity increases by about 400%. Does not work with every battery. Only try this on scrap batteries.

Epsom salts is Magnesium Sulphate
I don't know how this works.

My chemistry teacher at school, 50 years ago, told me it works by some how displacing the sulphate[ lead sulphate?] on the plates of the cell. something about numbers in the electrochemical series I think. It was a long time ago....My experience is that it definitely works. If you have a battery that has lost most of its capacity, give it a try. you have nothing to lose.

This is interesting, but not new.

I'm sure he's using a battery desulfator.

Check Out:

I've been using one of these for a while and it works great. Highly Recommended.

You can also find DIY articles, but you can hardly build it for what Battery Life Saver sells it for.

Here the link of the best plan I see so far for making your own Lead-Acid Battery Desulfator.

I want to build this circuit soon, as soon I find all the parts, now time to find free dead battery :)

Here in america you can buy epsom salt at your local market. its used for many purposes. One of them is you take a bath with a couple table spoons in a hot bath to relive stress

hello and thank you Neptune

i am trying this since 3 days and up to now it DOES WORK, my very old seal battery was dead, since 7 years not working, not able to keep a charge, and today i was able to output 200 watts for a long time ! i have not decharge it completly i prefer to recharge it completly until no more current enter in the battery, and then i will perform a full discharge

so it is a very good idea to buy many old batterys and get a power source when the local system is not working, very good investment to buy epson salt, i have tried to crystallize epson salt some years ago with no result, i am very happy to use it now to revive old battery

it work, i will report later how much it work
