SAFT LS14250 3.6V 1/2 AA Lithium 1200 mAh Axial Terminals

SKU CH-3S22-FJMPS

3.6 V lithium thionyl chloride ½ AA cell with axial terminals delivers 1200 mAh capacity, operates from -60 °C to +85 °C and retains charge for years with under 1 % annual self-discharge

  • High stable voltage for reliable operation
  • 1200 mAh capacity delivers long runtime
  • Axial terminals enable direct PCB mounting
  • Wide -60°C to +85°C temperature range
  • Low self-discharge under 1% per year

Power Profile

The SAFT LS14250 is a 3.6V 1/2 AA lithium thionyl chloride cell rated at 1200 mAh with axial terminals. It serves engineers and technicians who need a stable, high-voltage primary source for board-level backup, medical devices, telemetry or military and aerospace systems where replacement intervals stretch to decades.

Upgrade Path

It replaces older primary cells that sag under load or lose capacity quickly in storage. The jump is worth it when the application demands a flat discharge curve, less than one percent yearly self-discharge at 20°C and a proven safety record backed by IEC 86-4 and EN 50020 intrinsic-safety compliance.

Sustained Behaviour

The bobbin construction delivers a nominal voltage that stays high through most of the service life across a -60°C to +85°C range. Low magnetic signature and resistance to humid environments keep output predictable during multi-year deployments, while the non-flammable inorganic electrolyte maintains safety under continuous low-current draw.

Questions about this item

Will the 14.5 mm diameter and 25.25 mm height fit my 1/2 AA battery compartment?

Yes, the cell measures 14.5 mm in diameter and 25.25 mm in height, matching the standard 1/2 AA form factor for a snug fit.

How do I solder the axial terminals without damaging the lithium thionyl chloride chemistry?

Apply heat briefly to each axial lead; prolonged exposure can harm the internal bobbin structure and corrosive electrolyte.

When should I replace the battery given its low self-discharge rate?

With under 1% capacity loss per year at 20°C, expect decades of shelf life; replace when the powered device shows voltage sag under load.
