I want to buy A123 Systems 3.3v 2.5ah 26650 LiFePO4 cells that are on clearance at my local electronics shop but don't know how long they have been sitting on the shelves.
Is there any way to tell when they were manufactured and what is the maximum time (from the date of maufacture) they can be assumed to still be in prime condition?
Thanks
