Energizer 364 SR621SW Silver Oxide 0%Hg Mercury Free 10 Batteries

Energizer silver oxide batteries are specially designed to meet the varying power requirements of a wide variety of applications such as analog and digital watches, medial instruments, calculators, toys, and other portable electronics. However, they are primarily used for watch and calculater applications. They are ideal replacement batteries for any device. Sodium hydroxide (NaOH) electrolyte (low drain) cells are primarily designed for low drain continuous use over long periods of time, typically up to five years. This is commonly found in analog watch applications. Potassium hydroxide (KOH) electrolyte (high drain) cells are designed for continuous low drains with periodic high drain pulse demands. This is typical of applications such as LCD watches with backlight, analog watches with alarms, and calculators. Life expectancy in these applications is typically between one to three years.
