• Utility meters and measurement instruments
• Environmental and industrial sensors
• Memory backup for clocks, microcontrollers and data loggers
• Small medical devices and portable electronics with low current draw

Key specifications

• Nominal voltage: 6 V
• Nominal capacity: 150 mAh
• Cell type: button cell (high-voltage configuration)
• Typical application: low-current, long-standby devices
• Physical characteristics: compact cylindrical button form for holder installation

How to use

Install the cell into the device holder observing polarity markings and any orientation requirements. Ensure contacts and holder are clean and free of corrosion before insertion. Replace the battery when device performance indicates low voltage or when the device enters battery-fail states. Dispose of used cells in accordance with local regulations for battery recycling and hazardous waste.

Recommendations

Store unused cells in a cool, dry place away from direct sunlight and high temperatures. For optimal service life, avoid prolonged storage in fully discharged devices and remove the battery if the equipment will be unused for extended periods. Check device manufacturer guidance for recommended replacement intervals and compatibility with this nominal voltage and capacity.
