Twelve Saft LS14250 3.6V half-AA lithium cells in a row

SAFT

SAFT LS14250 ER14250 3.6V 1/2 AA 1200mAh Lithium standard battery 12-Pack

SKU CH-24ZE-RJX4F

Twelve 3.6 V 1/2 AA lithium thionyl chloride cells deliver 1200 mAh each with a low self-discharge rate and a wide -60 °C to +85 °C operating range

  • Reliable long-term power backed by 1200 mAh nominal capacity
  • Stable voltage maintained across most of the operating lifetime
  • Functions in extreme cold down to -60 °C and heat up to +85 °C
  • Minimal self-discharge under 1 % per year at 20 °C
  • Meets IEC 86-4 and EN 50020 intrinsic safety standards

12-pack 3.6V 1/2 AA lithium cells

This 12-pack supplies Saft LS14250 (ER14250) lithium thionyl chloride cells rated at 3.6 V and 1200 mAh each. The 1/2 AA form factor fits devices designed for this size. They serve industrial, medical, military, aerospace and telecom equipment needing long-life backup or primary power. The chemistry delivers a high, stable voltage across most of the discharge curve.

Replaces shorter-life primary cells

These cells replace alkaline or standard lithium primaries in applications where multi-year service and wide temperature tolerance matter. The jump is worth it when maintenance intervals must stretch to years and the load is low to moderate. They are not for high-drain devices that demand pulse currents beyond the bobbin design capability.

1200 mAh capacity with 25-year shelf life

Each cell holds 1200 mAh and loses less than 1% per year at 20 °C, giving up to 25 years of storage before use. Operating range spans -60 °C to +85 °C, so they handle extreme cold and heat. Capacity runs out under sustained high-current draw or when passivation limits pulse response after long storage.

Questions about this item

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

Yes, the LS14250 matches the standard 1/2 AA form factor at 14.5 mm diameter and 25.25 mm height.

Is soldering required or do these snap into a holder?

They are standard cylindrical cells with flat ends; they press into a 1/2 AA holder — no soldering needed unless the board has through-hole pads.

How long before the 1200 mAh capacity drops noticeably in storage?

Self-discharge is below 1 % per year at 20 °C, so usable capacity remains high for many years.
