ModMMax is on a distinguished road
In a previous incarnation, I worked as an electrician in a coal mine. This mine used battery operated vehicles called unitracks to deliver supplies to the underground operation (the shafts ran straight into the mountain so there was no vertical shaft). The batteries were wet cell 120v and we regularily dealt with suphate build up. We connected these batteries to enough alternating current to cause the battery to boil. Can't offer the electrical logic but it seemed to work. BTW, if I was going to try this to one of my 8D's, I would remove it from the boat first. There is a lot of spitting and sizzling that goes on and the occasional one would catch fire. I'm betting the high freq idea is a more civilized form of that coal mine practice.
