Saw this sealed wet cell battery on a table at the flea market this week. It seems to be complete but without the center terminal rod. I'm guessing the mostly loose crystals are the electrolyte solution that dried out. (That might have been prevented with some battery oil.) 8^D The top says BEACON, and the mint aqua glass jar has a large circle with a smaller one in the center embossed on one side. The base has what appears to be a CI near the center. This item is for sale [id=505397479].
