Yes I can't believe how well it works. I was very sceptical to give it a try but when I finally did..........I am very happy. That was the best advice I've had in a long time.

Please tell us again what the mineral oil trick is.

Take about 1 1/2 ounce of mineral oil and pour it in each cell of the batteries. It floats on top of the electrolye and reduces the loss of the electrolyte through evaporation

Thanks for the info.

FWIW on the OP...you can get the functional equivilent 8D AGMS for about $500 bucks saving 600 bucks.
8D AGM Battery - UB8D - Deep Cycle - As Low As $439.97!

The amount that I use is different:
2 oz per 12 volt cell and 4 oz per 6 volt cell.

The actual oz depends if the batts are 6v or 12v. I don't remember right now what the general guidlines are. However, the point is, to let each cell get low enough so when you add the mineral oil, it does cover the entire surface area of the cell. Once this is done, you can top off with distilled water.

This is very effective with with single stage chargers that boils the batteries continously. This is why this procedure was developed years ago before the advent of smart chargers. My experience says this is not necessary with a modern 3 stage charger. I go almost a year without adding water and I'm plugged in 24/7.
