SKU CH-1GTD-8DDDM

Six 3.6V 1/2 AA lithium cells with axial leads, 1.2Ah capacity and 10+ year shelf life

  • Battery type1/2 AA Lithium
  • 10+ year shelf life keeps spares ready
  • 6 V stable voltage through most of the discharge
  • 2 Ah capacity among the highest in 1/2 AA size
  • 55 °C to +85 °C operating range suits harsh environments
  • Axial leads enable direct PCB soldering

Industrial power pack

Six Xeno Energy XL-050FAX cells deliver 3.6V and 1.2Ah each in a 1/2 AA lithium format. The axial leads suit direct PCB soldering or custom harness builds. They target metering, telemetry and backup circuits that demand decade-long service without mains access.

Sealed axial construction

Stainless steel can with hermetic glass-to-metal seal resists humidity and operates from -55°C to +85°C. Self-discharge stays below 1% per year at 20°C, supporting a 10+ year shelf life. Continuous load is rated at 30 mA with 60 mA pulse capability for periodic transmissions.

Primary cell replacement

The pack replaces Tadiran TL-4902, TL-2150, TL-5101, TL-5111, TL-5151, TL-5902, Saft LS-14250 and LS-14250c, Toshiba ER3v and Sonnenschein SL-150/S, SL-350/S, SL-750/S equivalents. Not for rechargeable applications or loads exceeding the stated current limits.

Questions about this item

What voltage does the Xeno XL-050FAX deliver, and what continuous current can it sustain?

Each cell supplies 3.6 V and is rated for a maximum continuous current of 30 mA, with pulse capability up to 60 mA.

What are the exact dimensions of the 1/2 AA cells, and how much clearance do they need?

The batteries measure 14.5 mm in diameter and 25.2 mm in height, so the holder or enclosure must accommodate at least those clearances.

How are the axial leads attached, and what is the common mistake to avoid?

The leads are factory-welded to each end of the cylindrical cell; do not attempt to solder directly to the battery body, as heat can damage the seal and electrolyte.
