Results for sr920 battery
SR920 battery is a compact, high-performance button cell battery commonly used in small electronic devices such as watches, calculators, medical devices, and automotive key fobs. It offers reliable power delivery with a nominal voltage of 3V and a capacity of approximately 120mAh, making it ideal for low-power applications requiring long-term stability. This page provides detailed, practical insights into SR920 battery compatibility, performance, and usage tips to help users make informed purchasing decisions.
Understanding the search intent behind sr920 battery reveals that users are typically seeking a direct replacement for existing batteries in precision devices. Many consumers are looking for genuine or high-quality equivalents that match exact specifications to avoid device malfunction or premature failure. The SR920 battery is not interchangeable with other button cells like SR910 or LR920 due to differences in chemistry and voltage output—this is critical to understand before purchase.
To ensure optimal performance and safety, follow these steps when replacing or selecting an SR920 battery:
Users should avoid low-cost, unbranded SR920 batteries with vague specifications, as they often underperform or leak. Reputable brands offer better consistency and longer service life. For devices like digital watches or key fobs, a genuine SR920 battery can extend operational life by up to 30% compared to generic alternatives. Always store batteries in a cool, dry place to maintain performance.

- SR920 Battery
- A 3V lithium coin cell battery with a diameter of 9.5mm and a height of 2.0mm, designed for low-drain, long-life applications. It uses lithium-manganese dioxide (Li-MnO₂) chemistry, which ensures stable voltage output over time and excellent shelf life (up to 10 years).
- Compatibility
- Designed to fit devices that specifically require a 9.5mm × 2.0mm 3V battery. Always verify the device manual or existing battery code before replacement.
- Chemistry Type
- Lithium-manganese dioxide (Li-MnO₂) provides high energy density and consistent voltage, ideal for precision electronics.
To ensure optimal performance and safety, follow these steps when replacing or selecting an SR920 battery:
- Verify the battery size: 9.5mm diameter × 2.0mm height—any deviation may cause fitment issues.
- Check the voltage: Ensure the replacement is rated at 3V; do not use 1.5V alkaline or 1.55V silver-oxide cells.
- Confirm the chemistry: Only use Li-MnO₂ type; avoid mixing with other chemistries.
- Inspect for corrosion: Clean the battery compartment with a dry cloth before inserting a new battery.
- Dispose of old batteries properly: SR920 batteries are not recyclable in standard bins—use designated e-waste collection points.
