  • 2Ah capacity among the highest available today
  • 10+ year shelf life with under 1% annual self-discharge
  • Operates reliably from -55°C to +85°C
  • Axial lead termination fits Tadiran TL-4902 and Saft LS-14250 devices

24-pack 1/2 AA lithium batteries

This pack contains twenty-four Xeno Energy XL-050FAX cells, each rated at 3.6 V and 1.2 Ah with axial leads. The 1/2 AA lithium chemistry delivers a high operating voltage that remains stable across most of the service life. A shelf life exceeding ten years and a self-discharge rate below one percent per year at 20 °C make them suitable for long-term storage.

Ideal for low-drain industrial devices

These cells suit equipment requiring 30 mA continuous current or 60 mA pulse current, such as utility meters, alarm panels and data loggers. They operate reliably from -55 °C to +85 °C and resist humid environments. Buyers needing rechargeable cells or higher continuous current for motor-driven loads should consider other chemistries.

Verify voltage, size and current needs

Confirm the host device accepts 3.6 V primary lithium cells in the 14.5 mm by 25.2 mm form factor with axial-lead termination. Check that the maximum continuous draw does not exceed 30 mA and that the pulse demand stays within 60 mA. Cross-reference the listed Tadiran, Saft, Toshiba and Sonnenschein part numbers to ensure compatibility.

Questions about this item

What device or circuit must already accept a 3.6 V 1/2 AA lithium cell with axial leads for these batteries to work?

Any equipment designed for a 3.6 V 1/2 AA lithium primary cell with axial leads — such as utility meters, alarm sensors, or industrial loggers that list the XL-050FAX or cross-referenced models like Saft LS-14250 or Tadiran TL-5101 — will accept them directly.

How will these 3.6 V 1.2 Ah cells behave in a device that previously used a 3.6 V 1/2 AA battery with lower capacity?

The higher 1.2 Ah capacity extends operating time between replacements, while the 3.6 V nominal voltage and axial-lead fit remain identical; the device will simply run longer before the voltage drops below its cut-off threshold.

What should I measure to confirm each cell is performing correctly after installation?

With the device under its normal load, verify the cell voltage stays near 3.6 V and that the current draw does not exceed the 30 mA continuous or 60 mA pulse limits; stable voltage under load indicates the battery is functioning as intended.
