Purpose & Fit

The Saft LS14250 is a 3.6 V 1/2 AA lithium-thionyl chloride cell built for low-drain devices that need a stable voltage over years rather than hours. It suits backup power for circuit boards, utility meters, security sensors and similar industrial or professional electronics. Buyers who want a rechargeable cell or a high-current pulse battery for cameras or toys should look elsewhere.

Deciding Spec

The chemistry delivers a nominal capacity of 1200 mAh at 3.6 V with a self-discharge rate below 1 % per year at 20 °C. That combination of long shelf life and steady voltage is the single figure that determines whether the cell matches the application’s energy budget.

Sustained Behaviour

Operating range spans -60 °C to +85 °C while maintaining voltage stability for most of the service life. The bobbin electrode construction and inorganic electrolyte resist passivation and humidity, so capacity remains predictable during multi-year deployments rather than fading after a short burst.

Questions about this item

How long will the 1200 mAh capacity actually power a typical backup circuit?

At a constant 1 mA draw the 1200 mAh rating yields roughly 1200 hours; real runtime depends on the load profile of your specific circuit.

What does the 3.6 V lithium-thionyl chloride chemistry mean for voltage stability?

The Li-SOCl2 chemistry holds a high, stable voltage through most of the discharge curve, so the cell stays near 3.6 V until capacity is nearly exhausted.

Will the 14.5 mm by 25.25 mm dimensions fit a standard ½ AA holder?

Yes, the cell matches the ½ AA form factor with a maximum diameter of 14.5 mm and height of 25.25 mm, so it fits standard holders.
