Description

The 3-Pack 373 / 372 / SR916SW Rayovac Silver Oxide Button Batteries provides dependable, precision power for watches and compact electronic devices requiring miniature silver oxide cells. Manufactured by Rayovac, these batteries use silver oxide-zinc chemistry to deliver a nominal voltage of 1.55 volts. Their stable discharge characteristics make them particularly suitable for quartz watches and other low-drain electronics requiring consistent voltage and reliable operation.

Each Rayovac 373 battery measures approximately 9.5mm in diameter by 1.65mm in height, making it an exceptionally thin button cell suitable for compact battery compartments. The 373 / SR916SW designation is commonly used for low-drain watch applications, while the 372 / SR916W designation identifies a similar-sized high-drain version. Compatibility with both types should be verified against the device manufacturer's requirements. This package contains 3 Rayovac 373 silver oxide button cell batteries, providing a convenient supply for watch battery replacements and compatible miniature electronics.

Important Compatibility Note:

• Verify that your device requires a 373 / SR916SW 1.55V silver oxide button cell before installation.
• Each battery measures approximately 9.5mm in diameter by 1.65mm in height. Button cells with similar appearances may have different dimensions and may not fit correctly.
• The 373 / SR916SW battery is generally classified as a low-drain silver oxide cell, commonly used in analog quartz watches.
• The 372 / SR916W battery has the same nominal dimensions and voltage but is classified as a high-drain cell. A 373 battery should not automatically be substituted for a 372 in equipment requiring higher discharge capability.
• For watches with alarms, illumination, chronographs, or other higher-current functions, confirm that the selected battery meets the manufacturer's discharge requirements.
• Do not substitute 371 / SR920SW, 377 / SR626SW, 364 / SR621SW, or other button cell sizes unless specifically approved by the equipment manufacturer.
• Always confirm the original battery designation, voltage, chemistry, dimensions, and polarity before replacement.
• These Rayovac batteries are non-rechargeable primary silver oxide cells. Do not attempt to recharge them.
• Handle button cells with clean, dry hands or suitable nonconductive tools to avoid contaminating the battery contacts.
• Keep button cell batteries away from children and pets. Swallowed button batteries can cause severe internal injuries. Seek immediate emergency medical attention if ingestion is suspected.
• Do not short-circuit, crush, disassemble, heat, or expose batteries to fire.
• Store unused batteries in a cool, dry location and follow applicable battery recycling and disposal guidelines.
