So, I assume you've been using this stuff?
What are you thoughts on it?
Do you know what Univar charges for it? I think the outfit in Utah is something like $12/lb.
I've used EDTA before with mixed results, but mostly the problems I had could be traced back to my own stupidity.
I've had elcheapo car battery in our buick die on me and used EDTA to clean it up and it worked well. It did finally die because of a shorted cell, but it took it another year to do it.
I also brought a 4D back that had been sitting for at least two years out in the open in North Dakota. That was 8 years ago and the battery is still starting the tractor we mounted it in. This battery had loads of crud built up on the plates, enough in fact, that when you looked down the filler holes, you couldn't see any plates, just white/grey crap.
According to the instructions, you only use one teaspoon per cell for a T-105, but, me, I had to go more is better, and added 3 teaspoons to one T-145 and it caused the plates to be shorted out at the bottom where all the crud falls to.
Ever since then I've used 1 tsp/cell for a T-105 or a start battery and 2tsp/cell for an 8D or a T-145. I haven't had any L16's to work with yet, so I don't know how much to add to them.
If you are talking about the place in Orem, Ut. It's called:
Trailhead Supply 801 225 3931 or 801 226 6630
325 E. 1165 N.
Orem UT 84057

and their price went up not too long ago to $16.00/pound with $6.00 shipping, or a cost of $22.00.
Still, there are about 40teaspoons to a pound so you can do a LOT of batteries with the stuff.
At one teaspoon per cell you can do 13.3 T-105s.
I do have to mention that I use the 'desulphate' mode on my smart charger to help, but acording to what I've read, it isn't really required.
