A young Danish user of KZ650info.com named "Coninsan" submitted this post which I have presented verbatim. I intend to give it a go. The Alum was tough to find however, I needed to order it from a specialty store in Seattle. It was promised by Thurs. 24th. I will update as to what I have found out/experienced within the week.

Hurrah!
I would like to talk a little about something I have found out about how to recycle old dead lead batteries.
You can in just one hour to save it and give it more capacity than it had from the start. All you need is a little Alum, can be purchased in any general store, and an electric kettle.
When using lead batteries their mostly filled with sulfuric acid, and a relatively strong mix, as the battery is used sulfur is deposited on the lead terminals achieving "sulfurisation" you can harvest energy from this with the household substance Alum.
Alum is completely safe and is normally used to polish silverware, preserve food and wash clothes with. It is 100% environmentally friendly, so you can say to your battery gets a little greener after this.
Doing this will increase the capacity of your battery with up to 50%, typically between 20-30%. Volts remain the same. The saved battery can be expected to live up to twice as long as it did before because Alun is a much more stable and don't dissolve the terminals as the old acid does.
I've tried this with fresh batteries and it does not work. But with old batteries, I have gained a total rescue, and used them successfully on my old motorcycle, which still runs smoothly.
A 22ah battery ended up being a 28ah battery after this treatment, tested at constant load with a 12W bulb and measuring the time it remains lit. The battery could not hold power for more than 30min before treatment.
It is as simple as this:
1st First you take your old lead acid battery, which long ago does not work anymore, and has lost capacity. However, roasted and sealed batteries can not be saved.
2nd Empty the old acid out of the battery and dispose of in a propper way, usually down to recycling.
And clean the battery carefully with water a 4-5 times so you are sure that all the acid is out of battery. Be careful not to get too much on your fingers.
3rd Bring your electric kettle to boil for at least 1 liter of water.
To get the most out of your battery, use demineralized water, depending on how hard the water is in your area you will get varying results, therefore demineralized water is most optimally. I used plain tap water and it gave no complications.
4th When the water has boiled you let it sit in just a minute or two while you find a bowl.
5th Measure 100grams Alum up and gently poor it into the bowl, avoid spilling.
6th Poor, while stirring, 1 liter of water into the bowl, make sure that all the Alum is dissolved.
7th Cover the bowl and let it cool until it is hand warm.
8th Pour the mixture on to your battery up to the stated max level. Do not be afraid to get this on my fingers, it is quite harmless, it will nevertheless dry out your fingers, the remnants can just be poured down the drain.
9th charge up the battery and check levels on a constant rate, if the levels fall below the minimum, fill it only up to max with more water.
10th When your battery is finished charging, it is ready for use.
Good luck with your 'new' battery
