How to use

Install the cell following the equipment manufacturer’s polarity markings and guidelines for primary cells. Use the battery in devices designed for a 3.6V single-cell supply and avoid applications requiring rechargeable chemistry. Observe device-specified maximum load and temperature limits to maintain rated service life. Do not attempt to recharge, short-circuit, puncture or disassemble the cell. Dispose of the cell in accordance with local regulations for lithium primary batteries.

Usage recommendations

Store unused cells in a cool, dry place and avoid prolonged exposure to high temperatures to minimize self-discharge. For long-term deployments, confirm device current draw and pulse profile against the cell’s expected performance to estimate replacement intervals accurately. When installing in metering or telemetry equipment, ensure correct polarity and secure mechanical contact to prevent intermittent connection that can affect device operation.
