Re: optima battery prices............
There are limits to how much sulfation can be reversed. It's not a good place to be. Also, sulfate crystals will slough off and drop to the bottom of the battery case. When the layer of sulfate is deep enough to touch the plates, the cell shorts and you are done.
It's outrageous what they get for 6 volt batteries. Must be the low volume that pumps up the unit price.
