Omnicel ER14250 1/2 AA 3.6V 1200mAh 12-Pack

12-Pack 1/2 AA Primary Lithium Cells

This 12-pack supplies Omnicel ER14250 primary lithium thionyl chloride cells rated at 3.6 V and 1200 mAh each. They suit meters, sensors, alarms and other low-drain devices that require the 1/2 AA form factor. The chemistry delivers a stable 3.66 V open-circuit voltage and a wide operating range from -55 °C to +85 °C. Buyers needing rechargeable cells or higher continuous current should choose a different chemistry.

Simple Drop-In Replacement With Basic Precautions

Each cell measures 14.5 mm diameter by 25.25 mm height, matching the standard 1/2 AA footprint for direct insertion. Installation is straightforward: observe polarity, avoid mixing different models in series, and never attempt to recharge. Soldering tabs, if required, must be completed in seconds to prevent heat damage. Do not use any cell with a mangled casing.

Steady Voltage Over Long Service Life

Lithium thionyl chloride chemistry maintains nominal voltage through extended discharge, making these cells reliable for multi-year deployments. The 1200 mAh capacity supports low continuous loads such as 1 mA reference draws, while the 100 mA pulse test confirms recovery after brief higher demands. Storage below +30 °C in a dry, ventilated area preserves shelf life. Sustained high-current applications will deplete capacity rapidly and are not a suitable use case.
