Small silver cylindrical 1/2 AA lithium cell with axial wire leads

Xeno Energy

Xeno Energy XL-050FAX 3.6V 1/2 AA 1.2Ah Lithium Battery w/ Axial Leads

SKU CH-T01X-P94R4

A 3.6 V, 1.2 Ah 1/2 AA lithium cell with axial leads, 10-year shelf life and -55 °C to +85 °C operation

  • Battery type1/2 AA Lithium
  • 6 V stable voltage powers devices reliably
  • 2 Ah capacity supports long runtime in compact form
  • 10+ year shelf life with less than 1% annual self-discharge
  • 55 °C to +85 °C operating range suits extreme environments
  • Non-flammable inorganic electrolyte enhances safety in critical applications

Xeno Energy 1/2 AA Lithium 3.6 V 1.2 Ah

This 1/2 AA lithium primary cell delivers a nominal 3.6 V and 1.2 Ah capacity for long-life, low-drain applications. It suits metering, security, memory-backup and industrial sensor nodes that require stable voltage over years of service. The axial-lead termination allows direct PCB mounting without a holder. It is not rechargeable and must not be placed in a charging circuit.

Operating range -55 °C to +85 °C

The inorganic electrolyte remains non-flammable and non-pressurised at ambient temperature across the full -55 °C to +85 °C range. Maximum recommended continuous current is 30 mA with a pulse capability of 60 mA. Self-discharge stays below 1 % per year at +20 °C, giving a shelf life of 10+ years. Low magnetic signature and excellent humidity resistance support reliable operation in harsh environments.

Direct replacement for Tadiran TL and Saft LS series

The cell is compatible with Tadiran TL-4902, TL-2150, TL-5101, TL-5111, TL-5151, TL-5902, Saft LS-14250 and LS-14250c, Toshiba ER3V, Sonnenschein SL-350/S, SL-750/S, SL-150/S and generic 14250 references. No additional accessories, software or mounting hardware are bundled; the axial leads are the only mechanical feature. Users needing rechargeable chemistry or higher pulse currents must select a different product.

Questions about this item

How do I install the XL-050FAX with its axial leads, and what mistake should I avoid?

Solder the axial leads directly to the PCB pads; observe the marked polarity on the cell body and never attempt to recharge this non-rechargeable lithium battery.

What maintenance or replacement will the 1.2 Ah lithium cell need later?

No maintenance is required; after 10+ years shelf life or when voltage drops below useful level, replace the cell with another XL-050FAX or compatible 1/2 AA lithium type such as Saft LS-14250.

What limit appears first under sustained use of the 3.6 V battery?

The maximum recommended continuous current is 30 mA; exceeding this will reduce capacity and can trigger the 60 mA pulse limit prematurely.
