Battery desulfation

Sounds like buying a new battery would be cheaper and easier
 
Someone else was looking at that a couple of months ago.

Have not heard the results of that experiment yet.

.
 
The theory and techniques work but not on every battery and the battery doesn't come back 100%. Better to use those devices on batteries that aren't yet bad but if the battery wasn't bad you probably wouldn't be looking for a sulfation fix.

Like said it's easier just to pick up a new battery and know it's 100%

The DIY versions cost about $10 in parts and some of the commercial models boast 2 to 3 times the life of the battery. If that can be believed, that's a whole lot cheaper.
 
Until we went to solid state chargers, all vac tune chargers did that normally.

For about the last 10 years I have been using a charger with a desulfation mode on the farm with 7-8 batteries and it works well for recovering batteries for a good couple of years. I've even used it with our bulldozer which is a high drain start and it's kept that battery alive longer then any other battery we had in that unit. We've owned that farm all my life so I have a lot of history to compare to.
 
If you plan on using this device for preventive maintenance on a good battery, it would be cheaper to ensure said battery does not stagnate in a discharged state (< 80% of full charge), as that's when the rate of sulfation greatly increases....in a fully charged battery, the rate is negligible. If you plan on using it to restore a dead battery, it may or may not work...depends on how deeply the battery was discharged, and also the duration for which it sat in that state. That's the gist of the info. presented on another one I had looked at, at the bike show (Optimate, IIRC)...it was much more expensive, but did not guarantee the restoration of all batteries.
 
Epsom Salt / Distilled water

Epsom Salt / Distilled water

Desulfate a borderline battery with a mix of dissolved epsom salt and distilled water. Not a magic battery potion but it has extended life on batteries that were ready to be replaced. Make sure the salts are dissolved first in hot water, let water cool to under 100 degrees at least, top off battery. Charge on slowest rate you can, 2 amps or under until fully charged.

Im really interested in it for my stack of batteries that wont charge, if I get one working battery out of it, its a win.
 
I wouldnt bother with the DIY version - I tried it on several bike batteries and it made no difference whatsoever.
 
Yup when a battery starts sulfating, it is pretty much shot and waste of time to try desulfating. Even if you save just one, just a matter of time (a short matter of time at that) before it craps out anyways.

I am a huge believer in the BatteryMINDer charger/desulphator.
http://www.amazon.com/BatteryMINDer..._1?s=automotive&ie=UTF8&qid=1334248520&sr=1-1
First learned of this technology back in the 1990s when a colleague of mine was developing a system like this for charging M1A1 tank batteries for a US Army program. The fellow was former chief scientist for Exide battery and knew his stuff. It uses a pulsing technology that breaks up the sulfate crystals that cause the plates to short out. The system is computer controlled and monitors the response of the battery to determine optimum charging and pulsing conditions.

The consumer BatteryMINDer product has been around for awhile. I've had mine almost 15 years and it has paid for itself 10 times over. It won't save every battery, but I've used it to save many batteries. It's a much better product than the Battery Tender products which cost the same and do less.
