Twelve silver button-top lithium cells in a row

Xeno Energy

Xeno Energy XL-055F 3.6V 2/3 AA 1.65Ah Lithium Battery 12-Pack

SKU CH-EE9J-25X9D

Twelve 3.6 V 2/3 AA lithium cells deliver 1.65 Ah capacity, 10-plus-year shelf life and reliable operation from -55 °C to +85 °C

  • Battery Type2/3 AA
  • Ready for long-term deployments with a 10+ year shelf life
  • Delivers 1.65 Ah capacity in a compact 2/3 AA form factor
  • Operates reliably from -55°C to +85°C for extreme environments
  • Low self-discharge under 1% per year keeps power in reserve
  • Non-flammable inorganic electrolyte enhances safety in critical applications

Professional power for industrial sensors

These Xeno Energy XL-055F lithium cells deliver 3.6 V and 1.65 Ah in a 2/3 AA form factor. The button-top termination suits equipment that requires a positive contact nub. They target engineers maintaining remote telemetry, utility meters or security systems where battery changes are costly or impractical.

Wide temperature range and minimal self-discharge

Operation spans -55 °C to +85 °C, so the same pack serves Arctic pipelines and desert wellheads. Self-discharge stays below 1 % per year at 20 °C, and capacity loss during storage remains under 1 %. Continuous current is rated at 60 mA with 150 mA pulse capability, keeping voltage stable for low-duty-cycle transmitters.

Direct replacement for common ER and TL series cells

The XL-055F cross-references ER14335, SL-361, SL-761, TL-2155, TL-4955, TL-5155 and TL-5955 part numbers. The twelve-piece pack simplifies inventory for fleets that standardise on this chemistry. The jump is worth it when existing alkaline or lower-capacity lithium cells require annual swaps and the application can tolerate a non-rechargeable, corrosive-electrolyte primary cell.

Questions about this item

How do I install these 14.5 mm diameter button-top cells, and what step causes damage?

Insert each cell with the button top facing the positive contact; do not solder directly to the battery — use a holder or spot-weld tabs, because heat above a few seconds harms the internal chemistry.

What maintenance or replacement will these 3.6 V 1.65 Ah lithium cells need later?

They are non-rechargeable primary cells; after delivering their 1.65 Ah capacity they must be replaced — expect 10+ years shelf life with under 1 % annual self-discharge at 20 °C.

What limit appears first during sustained use of these 60 mA continuous-rated batteries?

The 60 mA maximum recommended continuous current is the first ceiling; drawing more causes voltage sag and reduces usable capacity before the 150 mA pulse limit is reached.
