Energizer 377 Watch/Electronic Battery

Silver Oxide Batteries are designed for continuous low-drain and high pulse on demand so they are perfect for watches, toys, glucose monitors, calculators and more.

Mercury-free battery also has good resistance to shock, vibration and acceleration. Cell size is 377. It is a replacement for 376/377, 377BP, D377, SB-AW, SR626SW and SR66.
