Twelve half-AA lithium cells with axial leads in a row

Xeno Energy

Xeno Energy XL-050FAX 3.6V 1/2 AA 1.2Ah Lithium Battery 12-Pack

SKU CH-PCFR-68FSN

Twelve 3.6 V 1/2 AA lithium cells with axial leads deliver 1.2 Ah capacity, 10+ year shelf life and operation from -55 °C to +85 °C

  • Battery type1/2 AA Lithium
  • 6V high operating voltage stays stable across the application lifetime
  • 2Ah capacity among the highest nominal ratings available today
  • 10+ year shelf life with less than 1% self-discharge per year at 20°C
  • Operates reliably from -55°C to +85°C in humid environments
  • Non-flammable non-pressurised inorganic electrolyte for safe long-term storage

12-Pack 1/2 AA Lithium Primary Cells

This pack contains twelve Xeno Energy XL-050FAX 3.6V 1.2Ah lithium batteries with axial leads. They are non-rechargeable primary cells designed for long-life, low-power applications such as utility meters, security sensors and industrial data loggers.

Current and temperature operating envelope

Continuous discharge is limited to 30 mA with pulse capability up to 60 mA. The chemistry operates from -55°C to +85°C and holds a shelf life of 10+ years with less than 1% annual self-discharge at 20°C. The inorganic electrolyte is non-flammable and non-pressurised at ambient temperature.

Physical fit and replacement cross-reference

Each cell measures 14.5 mm diameter by 25.2 mm height and weighs 9 g. Verify that your device accepts axial-lead 1/2 AA dimensions and a 3.6V primary chemistry. Direct replacements include 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, SL-150/S. Do not attempt to recharge.

Questions about this item

Should I buy the 12-pack or look for a smaller quantity?

The listing is a 12-pack of 1/2 AA 3.6 V 1.2 Ah lithium cells with axial leads; no smaller pack is offered in this SKU.

What does the 1.2 Ah rating mean for a device that draws 30 mA continuously?

At the maximum recommended continuous current of 30 mA the 1.2 Ah capacity provides the rated energy until the voltage drops below the usable threshold.

The axial-lead termination — does it fit standard 1/2 AA holders or only soldered connections?

Axial leads are designed for direct PCB soldering; they do not fit spring-loaded battery holders made for button-top cells.
