Owner Reviews, Ratings, Comments and Criticism
I'm pretty used to buying batteries online and finding they had been made long before I ordered them (had some CR123 with experations the next month from another vendor). In at least my case, my batteries from this vendor show a production date of 3/30/10...and I ordered them on April 18th. You can't get any younger batteries (exp is Mar2016). I'll be checking this distrbutor out for the rest of my battery needs.
