Silver oxide battery SR series

circular1.5 Vprimary

The silver oxide battery is a primary battery that mainly uses silver oxide as the positive electrode active material, zinc as the negative electrode active material, and an aqueous alkali solution as the electrolyte solution.
Due to its high energy per unit volume and stable operating voltage characteristics, it became established as a power supply for quartz watches (analog watches) requiring high accuracy. In recent years, applications have expanded to a wide range of fields such as medical devices equipped with Bluetooth® Low Energy.

Features
- Stable operating voltage and high capacity
Higher capacities than alkaline button batteries

- Superior load characteristics
The long-life low-drain type (SW), suitable for equipment that operates for long periods of time with light loads such as analog watches.
The high-drain type (W), suitable for equipment expected to be used for short periods of time with heavy loads such as medical equipment and multifunction digital watches with alarms and LED lights.

- Superior leakage resistance
Suppresses the electrolyte from rising up and seeping out - a basic phenomenon of alkaline electrolytes.

- Excellent capacity retention rate
For the main models, the SR920SW, SR626SW, and SR621SW, an annual capacity deterioration rate of about 2% has been achieved for standard capacity.

- Mercury-free for the environment
All models of Maxell’s silver oxide batteries are manufactured without using mercury or lead as part of Maxell’s efforts to reduce its environmental impact. These batteries comply with the EU Battery Directive.

Applications
- CGM
- Capsule endoscopes
- Analog watches/Digital watches
- Bluetooth® Low Energy devices
