Murata 389/390 SR1130SW 1.55V Silver Oxide Battery - 10 Pack

Product Description

The Murata 389/390 SR1130SW 1.55V Silver Oxide Battery provides clean, consistent power tailored for precision timepieces, medical instruments, and compact electronic devices. Built on the legacy of Sony’s world-renowned micro-battery engineering (acquired by Murata), this battery offers high energy density, a flat discharge curve, and dependable performance.

Featuring Murata’s proprietary leak-resistant sealing technology and a specialized J-shaped gasket, this button cell ensures maximum leak protection to safeguard delicate internal movements. The dual-cross designation (389/390) makes it a versatile power solution compatible with both high-drain functions (such as watch alarms or backlights) and low-drain continuous operation in standard analog watches.

Key Features

• Stable 1.55V Discharge: Delivers a constant voltage output from start to finish, maintaining accurate timekeeping and sensor readings.
• Patented Anti-Leak Technology: Engineered with advanced sealing structure and a J-shaped gasket to prevent liquid leakage and internal component corrosion.
• High Capacity & Energy Density: Advanced Japanese silver oxide chemistry packed into a compact 11.6 mm x 3.05 mm form factor.
• Eco-Friendly & Mercury-Free: Manufactured with mercury-free (0% Hg) for safety and environmental sustainability.
• Universal Cross-Reference: Directly replaces battery sizes 389, 390, SR1130SW, SR1130W, SR1130, AG10, SG10, and LR1130.
• Precision Japanese Manufacturing: Produced in Japan under rigorous quality standards for high reliability and low self-discharge rates.
