We have read in some previous posts about EDTA restoring inverter batteries to an "almost new" state.
After reading clinical studies from the links that were posted, we ordered some EDTA (photographic quality) from the US.
Here are the results so far.
1) My friend has 2 Trace inverters with 12 batteries apiece that, although only a couple of years old, were in a mess, probably from not equalizing them on a monthly basis.
10 of the 24 batteries were completely useless and would not accept or hold a charge, and the other 14 were running hot and about to give up the ghost.
After treating all the batteries with EDTA, with approx a double dose, (2 tablespoons per cell), and operating them for less than a week, they now are running cool, accepting and holding their charge like new, or nearly new batteries. (Cost to fix, approx. $70 US for the whole job)
2) My mechanic has a cheapo inverter with 8 batteries and he complained that they did not last as long as when they were new. As his inverter has no equalize feature, I'm not surprised. We treated them also with a double dose and although not a clinical observation, he tells me now that they used to last him 6 hours and now last 11. (Cost to fix, $14 US)
3) A friend dropped off 4 Trace batteries that he had lying around and although we did not know what condition they were in in, we went ahead and gave them all a double dose treatment. After hooking them up to my Trace 3.6, along with my other batteries, 3 of them looked promising and the other one was still not accepting the charge, so I added another single dose to the 3, and another double dose to the bad one. They are, after being hooked up for less than a week, all running cool and accepting and holding their charge. (cost to fix, approx. $20 US)
CONCLUSIONS...
As the cost for experiment number 1 is the same or less than the cost of buying one single battery, the results are outstanding.
I believe that adding a single does per year to one's batteries would maintain them, and this would cost only approx. $5 US per bank of 4 batteries.
I don't know just how many years one can make "treated batteries" last, but I did read about a fellow who was still running his "treated batteries" after 18 years.
If you have any doubts or don't believe the results, bring me your old batteries. Maybe I'll go into the used battery business.
PS: If you are now operating with some old "hard to charge" batteries, you have to consider how much extra you are paying for electricity to try to charge batteries that don't want to take the charge. This alone justifies the cost of adding in the EDTA.
PPS: We plan to experiment with car batteries as well.
