I reviewed some Panasonic CR123A batteries a while back. Recently it’s been brought to light by a rep at Panasonic, that the batteries I received were most likely counterfeit. Panasonic does not package CR123A batteries in “pillow packs”, and that most of the Panasonic batteries found on Ebay are in fact, counterfeit.
The email I received reads:
The Panasonic CR-123A batteries you purchased on e-bay were clearly counterfeit. Panasonic does not package our batteries in “pillow packs”. Our continuing monitoring of e-bay tells us that roughly 80-90% of all Panasonic CR-123A batteries sold on e-bay are counterfeit.
