Industrial 3.6V Lithium Cell
The SAFT LS14250 is a lithium thionyl chloride battery that delivers a stable 3.6V output and 1200 mAh nominal capacity. It is built with concentric bobbin electrodes and solder pins for direct PCB mounting. The chemistry provides a low self-discharge rate of less than 1% per year at 20°C, supporting long-term backup power for circuit boards, medical equipment, and telecommunications gear.
Suited for Permanent Solder Installations
This cell suits engineers designing devices that require a primary power source soldered permanently in place, such as utility meters, military aerospace systems, or remote sensors operating from -60°C to +85°C. It is not for users needing a rechargeable cell, a snap-in holder format, or a consumer AA replacement for household electronics.
1200 mAh Capacity for Low-Drain Longevity
The 1200 mAh capacity comfortably handles microamp-level backup loads for years, making it ideal for memory retention and real-time clock circuits. It runs out quickly if subjected to continuous high-current discharge or pulsed loads beyond the bobbin design's low-rate capability, limiting its use in high-drain applications.

Questions about this item
What circuit-board footprint fits the 14.5 mm diameter and 25.25 mm height of this LS14250 cell?
Design the PCB with a 14.5 mm mounting hole pattern and 25.25 mm clearance; the solder pins are spaced for direct through-hole attachment.
Can the -60 °C to +85 °C operating range handle a legacy board that only specifies -20 °C to +60 °C?
Yes — the wider temperature window means the cell will still deliver 3.6 V in environments where the older board would stop working.
How do I confirm the 1200 mAh capacity is available after soldering?
Measure open-circuit voltage — a fresh cell reads near 3.6 V — then apply a known load and verify the voltage remains stable for the expected runtime.
