Five hundred small silver lithium cylinders with axial leads in bulk packaging

Xeno Energy

Xeno Energy XL-055F 3.6V 2/3 AA 1.65Ah Lithium dry cell battery 500-Pack Axial Leads

SKU CH-X3SF-2RGTR

500 lithium 2/3 AA cells deliver 3.6 V and 1.65 Ah with axial leads, 10-year shelf life, and -55 °C to +85 °C operation

  • Battery type2/3 AA
  • Ready for long-term deployments with 10-year shelf life
  • Stable 3.6 V output through most of the operating lifetime
  • 65 Ah capacity among the highest in this form factor
  • Operates reliably from -55 °C to +85 °C
  • Axial leads simplify direct soldering to circuit boards

500-Pack 3.6V 2/3 AA Lithium Cells

The Xeno Energy XL-055F is a primary lithium dry cell supplied in a 500-piece pack. Each unit delivers 3.6 volts and 1.65 Ah capacity in the 2/3 AA form factor with axial leads for direct PCB mounting. The chemistry provides a shelf life of 10+ years and less than 1% annual self-discharge at 20°C.

Suited for long-life IoT.

These cells suit designs that demand stable voltage over years at low continuous currents up to 60 mA. They are not for applications requiring rechargeable chemistry, higher continuous drain, or consumer AA-replacement use. Buyers needing solder-tab or button-top terminations should look at a different SKU.

Verify 14.5 mm diameter and 33.5 mm height clearance

Confirm the PCB footprint accepts axial-lead spacing and that the operating envelope stays within -55°C to +85°C. Ensure the system never attempts recharging and that mixed cell types are not used in series. Store stock below 30°C in a dry, ventilated area.

Questions about this item

What device voltage is needed to run the 3.6 V XL-055F cells?

The cells deliver a nominal 3.6 V, so the equipment must be designed for a 3.6 V lithium primary supply.

Will these axial-lead batteries fit the same footprint as my existing ER14335 or SL-361 packs?

Yes, the XL-055F is listed as compatible with ER14335, SL-361, SL-761 and several TL-series models, sharing the 2/3 AA size and axial termination.

How can I confirm the pack is healthy after installation?

Measure open-circuit voltage — it should read close to 3.6 V — and verify the device draws no more than 60 mA continuous or 150 mA pulse during normal operation.
