Are you replying to my comment about using stainless steel screws to plug the vent holes I added to a D34 Optima? If so, it is a temporary measure to experiment on one that is "bad". And, they are only #6 screws, and don't touch the electrolyte (they are just in the cover). First reports: The battery was fully charged, then I added 1 teaspoon of water to each cell. This lowered the open circuit voltage slightly, from 13.13v to 12.94v. The battery was put back on charge, and has been charging all day on a trickle charger. The voltage is still rising, and currently at 14.20v at 0.4 amps. About 9ah has gone into it so far. I plan to leave it on until the voltage stops rising, and then test its capacity. -- Lee A.
