Renata 377 / SR626SW Silver Oxide Button Battery 10-Pack

10-Pack Silver Oxide Button Cells

This 10-pack supplies Renata 377 / SR626SW silver oxide button cells rated at 1.55 Volt. They suit watches, calculators, medical devices and other compact electronics that require this specific coin format. The silver oxide chemistry delivers stable voltage through the discharge curve. Each cell measures 6.8 mm diameter by 2.65 mm height.

Compatibility check before ordering

Verify that your device specifies 377, SR626SW or one of the listed equivalent codes such as LR626, AG4, V377, 376 or 606. Confirm the physical dimensions of 6.8 mm by 2.65 mm fit the battery compartment. Ensure the application expects 1.55 Volt silver oxide chemistry rather than 1.5 Volt alkaline types. Do not use if the device requires a different voltage or a rechargeable cell.

Sustained discharge characteristics

Silver oxide chemistry provides a flatter voltage curve than alkaline equivalents, maintaining output over longer periods. The manufacturer states these cells last five times longer than the alkaline equivalent under comparable loads. This makes them suited for continuous low-drain use where frequent replacement is impractical. They are not designed for high-current pulse applications.
