Common Applications
ITTA SR920SW batteries work with compatible quartz watches and small electronic equipment.
For example, certain analog watch movements require SR920SW or 371 silver-oxide cells.
Additionally, some precision electronic devices use the same battery format. Nevertheless, compatibility depends on the manufacturer’s specified battery model.
SR920SW vs 371 Battery
SR920SW and 371 commonly identify the same silver-oxide battery format.
Both designations generally refer to a 1.55V button cell with similar dimensions. Therefore, customers may encounter either model number when searching for watch battery replacements.
Always follow the watch manufacturer’s instructions to confirm compatibility.
SR920SW vs SR920W
Although SR920SW and SR920W batteries share similar dimensions, their discharge characteristics can differ.
SR920SW typically suits low-drain watch applications. In contrast, SR920W generally refers to a high-drain variant.
Therefore, choose the battery model specified by your watch manufacturer rather than relying only on physical size.
Silver Oxide vs Alkaline Watch Batteries
Silver-oxide batteries generally maintain a more stable voltage throughout discharge.
In comparison, alkaline button cells may offer different voltage-discharge characteristics.
Consequently, many compatible quartz watch movements use silver-oxide cells.
For reliable operation, follow the battery chemistry recommended by the device manufacturer.
How to Replace an SR920SW Watch Battery
- Confirm that your watch requires an SR920SW or 371 battery.
- Carefully open the watch case using suitable tools.
- Identify the original battery’s polarity and orientation.
- Remove the exhausted cell without damaging the watch movement.
- Install the replacement battery with the correct polarity.
- Close the case securely and check watch operation.
For water-resistant watches, consider professional replacement to help protect the case seals.
Important Battery Safety
- Never recharge silver-oxide button cells.
- Avoid short-circuiting or damaging battery terminals.
- Keep new and used batteries away from children.
- Do not expose batteries to fire or excessive heat.
- Remove exhausted cells promptly.
- Follow local battery-recycling and disposal requirements.
Warning: Swallowed button batteries can cause life-threatening injuries. Seek emergency medical assistance immediately if you suspect ingestion.
Frequently Asked Questions
What is the voltage of the ITTA SR920SW battery?
Each cell provides a nominal voltage of 1.55V.
