Found out today that the remaining bottle I have is expired and cannot be filled again until it is recertified. They're good for 5 years and the date is stamped into the top side of the cylinder. Good news is that it will take a couple of days, but, a local welding supply co. will do it for $20. This is cool info on the equipment and how it's done.
