Thanks for the reply like the infinite shelf life. They do not have acid in them I was told. Swap meet is only once a month and the guy has several cannot say how he acquired them on here but definitely not stolen. I will check my CF battery and PN and dimensions before I go next month. No he does not have a web site and the asking price was $50 definitely cheap in my book. Acid is $ 7.95 at NAPA for a quart.
