100-Pack 1/2 AA Lithium Cells for Long-Term Devices

This pack supplies one hundred Xeno Energy XL-050FAX batteries, each a 3.6V 1.2Ah lithium thionyl chloride cell with axial leads. They suit equipment that needs a very low self-discharge rate and a shelf life beyond ten years. Typical uses include utility meters, alarm panels, tracking beacons and industrial data loggers where replacement access is difficult or costly. The cells are not rechargeable and must not be placed in a charger.

Thermal Behaviour and Power Profile

The chemistry operates from -55°C to +85°C with a stable voltage through most of the discharge curve. Maximum recommended continuous current is 30 mA and pulse capability reaches 60 mA, so the cell runs cool in normal metering loads. Self-discharge stays below one percent per year at 20°C, preserving capacity during storage. The inorganic electrolyte is non-flammable and non-pressurised at ambient temperature, though it is corrosive if the case is breached.

Axial Leads and Cross-Reference Compatibility

Axial leads allow direct soldering to a PCB without a separate holder, reducing assembly height and part count. The 14.5 mm diameter and 25.2 mm height match the 14250 form factor. The pack covers replacements for Tadiran TL-4902, TL-2150, TL-5101, TL-5902, TL-5111, TL-5151, Saft LS-14250 and LS-14250c, Toshiba ER3V, and Sonnenschein SL-350/S, SL-750/S and SL-150/S. Devices needing higher continuous current or a rechargeable cell cannot use this battery.

Questions about this item

How do I solder the axial leads on the XL-050FAX without damaging the 3.6V lithium cell?

Use a temperature-controlled iron at the lowest setting that melts solder, apply heat for under two seconds per joint, and keep the body below 85°C to avoid electrolyte venting.

After ten years on the shelf, will the 1.2Ah capacity still meet the 30mA continuous rating?

Self-discharge stays under 1% per year at 20°C, so a fresh cell retains virtually all 1.2Ah and the 30mA continuous limit is unchanged.

At what ambient temperature does the 60mA pulse capability start to drop off?

The specified operating range ends at +85°C; above that the internal resistance rises and the 60mA pulse rating can no longer be guaranteed.
