What has been won by the brave at great cost can be lost cheaply by fools and once gone can rarely be regained and only then at great cost.

I imagine my chances of scoring picric acid are about as high as seeing a tyrannosaurus rex ambling down the lane. But it seems interesting.

I purloined this from an online encyclopaedia:-

Corrosion behaviour of negative and positive electrode of lead acid battery has been examined in the battery fluid (5 M H2SO4) containing small amount of picric acid, mixtures of picric acid and phosphoric acid as additives from Tafel polarization study. Analysis of the corrosion parameters indicates that picric acid enhances corrosion rate of negative plate but it acts as an inhibitor to the positive plate. A mixture of picric acid and phosphoric acid however acts as corrosion regulator to both the plates. The results are well explained in terms of adsorption of picric acid and electrode surfaces and formation of lead picrate.

I suspect that Epsom salts used wisely may be of some benefit - for a knackered battery.

What I'm looking for is something which prevents the lead sulphate from ever going hard. I don't know what that might be at the moment.

Starting batteries with their porous plates are difficult candidates for rejuvenating if they are sulphated. The sulphation gets into the pores, expands, and then causes 'shedding.' Prevention seems the only cure really, unless the battery is somewhat oversized for the vehicle it is used in.

The sturdier plates (solid) of traction batteries are more responsive, And I have noticed this too. ie - my little 24 V electric scooters use batteries that just keep going, and have done for a couple of years, and those two 12 V deep cycle batteries, as well as the pair in a repaired electric bicycle were both brought back from the dead with no electrolyte and had been sitting around in this condition for years. Basically I added some distilled water and pulsed carefully watching and adjusting the power so they didn't get too warm or gassed too much.

I also have far more success with so-called 'marine' batteries, and larger-type truck batteries. I gather this is due to the plates being more solid than the SLI batts used in cars.

* There are no end of sites on the 'net which play swings and roundabouts with different chemicals and claim they work because one chemical counteracts the deletarious effects of another. - It reminds me of going to the doctors to have pills to counter the side-effects of the pills which were taken to prevent the side-effects of the pills which were prescribed to lessen the harmful effects of some pills which had been recommended to alleviate the si... .

* But I'm all ears. :D

Fix your 13 year old car battery which you have been using as a doorstop for the last three years with 'Scamm's additive.'

Three gallons in each cell of your car battery will:-

Make the plates as hard as diamonds. :D

Automatically makes little shelves (millions of them) neatly arranged on each side of the separator which have micro-hoists which lift the sulphate crystals on board and very tiny (Chinese?) workmen who have acid-proof coats and aqualung hit them with hammers.

Only $14,998.90 for a quart.

yes hydrazine sulphate is used for a cancer cure in some countries
but it is also known for causing it, but i cant remember where i read it?

it also could have been a hyda- something??

and regular epsom salts will work

just boil the water or peroxide first to get it to completely disolve
