Key Technical Specifications

• Voltage: 1.55 V (nominal)
• Capacity: Approximately 24 mAh for the SR626SW variant; slightly higher for larger sizes such as the 377/376 series.
• Dimensions: Common sizes include 6.8 mm × 2.6 mm (SR66, SR626SW) and 7.0 mm × 3.1 mm (377/376).
• Chemistry: Silver Oxide (Ag₂O), known for its low self‑discharge rate and high energy density.
• Shelf Life: Up to 10 years under optimal storage conditions, ensuring readiness when the device is first powered on.
• Temperature Range: Operates effectively from –20 °C to +60 °C, making it suitable for both indoor and outdoor applications.

Why Silver Oxide?

The silver oxide chemistry offers several advantages over alkaline or lithium alternatives:

• Stable Voltage Output: Maintains a consistent 1.55 V throughout most of its discharge cycle, which is critical for devices that rely on precise voltage thresholds.
• Low Self‑Discharge: Retains up to 90% of its charge after five years when stored at room temperature, reducing the need for frequent replacements.
• High Energy Density: Provides more energy per unit volume compared to many other button cell chemistries, extending device operation time.
• Environmental Considerations: Contains no mercury or heavy metals that are common in some older battery types, aligning with modern environmental standards.

Common Applications

The Energizer Silver Oxide Button Cell Battery is widely used across a spectrum of devices. Below are some typical use cases:

• Watches and Clocks: Powers quartz movements, LED displays, and internal circuits.
• Medical Devices: Supplies energy to glucose monitors, blood pressure cuffs, and hearing aids where reliability is paramount.
• Security Systems: Fuels keyless entry modules, alarm sensors, and motion detectors that require long standby periods.
• Consumer Electronics: Operates remote controls, wireless mice, and small gaming devices.
• Industrial Equipment: Powers RFID tags, sensor nodes, and other low‑power industrial control units.

Installation Tips

Proper installation ensures maximum performance and safety. Follow these guidelines when inserting the battery into your device:

1. Check Polarity: Verify that the positive (+) side of the battery aligns with the marked terminal in the device’s compartment.
2. Clean Contacts: Remove any corrosion or debris from the contacts to prevent voltage drops.
3. Gentle Insertion: Avoid applying excessive force; a gentle push is sufficient due to the small size of the cell.
4. Avoid Short Circuits: Ensure that no conductive material bridges the positive and negative terminals during insertion or removal.

Storage Guidelines

To preserve battery life, store unused batteries in a cool, dry place. Keep them away from high temperatures, moisture, and direct sunlight. If you plan to keep batteries for extended periods, consider storing them in a sealed container with desiccant packs to mitigate humidity.

Environmental Impact and Recycling

The Energizer Silver Oxide Button Cell Battery is designed with environmental responsibility in mind. While it does not contain mercury, the silver component requires responsible disposal. Many regions offer battery recycling programs that safely recover precious metals and prevent hazardous materials from entering landfills.

Performance Comparison
