Energizer CR2016 Lithium Batteries - 2 Packs of 5 (10 Batteries Total) - Long-Lasting Power for Watches, Calculators, Key Fobs & Small Electronics

Giving these 5 stars because they arrived fast, packaged well, and appear to be genuine Energizer brand.The cells have an Exp date of 05/2034, which means basically 9 years from now.Because some reviewers stated their batteries were DOA, I used the sharp probe on my DVOM to pierce the packaging and check each cell and they all read more than 3.3Volts. Good enough for me!
