Maxell 392 SR41W 1.55V Silver Oxide Battery - 5 Pack

Product Description

The Maxell 392 (SR41W) is a 1.55V high-drain silver oxide button cell battery engineered to provide reliable, long-lasting power for precision electronics. Made in Japan, this mercury-free battery features Maxell’s high-energy density technology and leak-resistant design, delivering a flat discharge rate to ensure consistent voltage output throughout its lifespan.

Because it is a high-drain cell ("W" series), it is specifically designed to handle devices with continuous base loads as well as periodic high-power demands, such as watches with backlights, alarms, or digital displays. It is widely used in wristwatches, medical devices, digital thermometers, calculators, and small electronic instruments.

Key Features

• HIGH-DRAIN RELIABILITY (SR41W): Engineered specifically for high-drain electronic devices requiring continuous base currents with intermittent high-pulse demands such as watch alarms, LED backlights, and digital displays.
• STABLE 1.55V VOLTAGE OUTPUT: Advanced Silver Oxide (Ag2O/Zn) chemistry provides a flat discharge voltage profile to ensure long-lasting, consistent power from start to finish without continuous voltage drop.
• SUPERIOR LEAK RESISTANCE: Manufactured in Japan utilizing Maxell’s proprietary cross-linking technique and precision sealing process to prevent electrolyte leakage and protect sensitive micro-circuits.
• 0% MERCURY & ENVIRONMENTALLY SAFE: Eco-friendly mercury-free formula (Hg-Free) complies with modern environmental standards while offering high energy density in a compact size.
• UNIVERSAL CROSS-COMPATIBILITY: Perfect 1:1 replacement for 392, SR41W, D392, V392, GP392, SR41, 247B, SB-B1, 280-13, and LR41 (alkaline equivalent). Ideal for watches, medical devices, digital thermometers, calculators, and key fobs.
