1/2 AA lithium thionyl chloride cell

The Omnicel ER14250 is a primary lithium battery that delivers a nominal 3.6 V and 1200 mAh in the compact 1/2 AA footprint. It suits devices that need long-term, low-current power such as utility meters, security alarms, medical instruments and board-level backup circuits.

Steady low-current discharge across extreme

Lithium thionyl chloride chemistry maintains a stable voltage over years of continuous microamp to milliamp draw rather than short high-current bursts. The cell operates from -55 °C to +85 °C, so outdoor telecom gear, water meters and aerospace systems keep running through seasonal extremes without voltage sag.

Hermetic cylindrical case

The stainless steel can measures 14.5 mm wide by 25.25 mm tall and weighs roughly 12 g, fitting existing 1/2 AA holders without adapters. A pressure vent and UL approval add safety for permanent installation, while the non-rechargeable design eliminates charging circuitry and prevents accidental recharge attempts.

Questions about this item

How much heat can the Omnicel ER14250 withstand during continuous operation?

The cell operates reliably from -55°C to +85°C, so it tolerates sustained high ambient temperatures without performance loss.

What device or holder is required to use this 1/2 AA lithium cell?

You need equipment with a 14.5 mm by 25.25 mm battery compartment and contacts for a 3.6 V primary lithium thionyl chloride cell.

Will this 3.6 V, 1200 mAh battery replace an older Saft LS-14250 in my meter?

Yes, the ER14250 is listed as a direct equivalent for the Saft LS-14250 and other 14250-series cells used in utility meters.
