Energizer 371 or 370 Button Cell Silver Oxide SR920SW Watch Battery Pack of 5 Batteries

I got five of these tiny batteries for what one battery would cost me at a local discount chain store. The service was excellent and speedy. I have no idea what the shelf life is on these batteries. At the rate of one battery every two years, I'll find out in 2018 or 2019.

The batteries were "fresh", but more importantly, the reseller was excellent with continuous communications and shipping statuses. It was a small purchase, but I would buy from this third party seller again.
