Cylindrical AA lithium battery with axial leads, silver metal finish

Tadiran

Tadiran TL-5104/P 3.6V AA 2.1Ah Lithium Battery with Axial Leads

SKU CH-BC9J-B65VX

AA-size 3.6V lithium thionyl chloride cell delivering 2.1Ah with axial leads for direct PCB mounting

  • High stable voltage through most of service life
  • 1 Ah capacity among highest available for AA lithium
  • Operates reliably from -60 °C to +85 °C
  • Less than 1 % self-discharge per year at 20 °C
  • Axial leads enable direct PCB mounting

Purpose-built power cell

The Tadiran TL-5104/P is a 3.6V AA lithium thionyl chloride cell rated at 2.1 Ah with axial leads for direct PCB mounting. It serves engineers and maintenance teams who need a primary power source that delivers stable voltage across a wide temperature span and a shelf life exceeding 10 years.

Integration profile

The 14.5 mm diameter by 50.5 mm height form factor fits standard AA footprints while the axial leads free up board space otherwise occupied by a holder. Operation from -60 °C to +85 °C lets the cell replace multiple chemistries in remote sensors, utility meters or industrial loggers without thermal management hardware.

Compatibility matrix

Cross-reference tables list direct equivalents including Saft LS-14500 series, Sonnenschein SL-360/S and SL-760/S, Xeno XL-060F and several Tadiran TL models so procurement can consolidate part numbers. The non-rechargeable chemistry and corrosive electrolyte require careful handling and storage below 30 °C, ruling out designs that expect recharging cycles.

Questions about this item

How long can the 2.1 Ah lithium thionyl chloride cell deliver its rated capacity before voltage drops off?

The ER14505 chemistry maintains a high, stable operating voltage through most of the 2.1 Ah discharge life, so usable capacity remains close to the rated figure until near the end of discharge.

What temperature extremes can the TL-5104/P withstand during continuous operation?

The cell is rated for an operating range of -60 °C to +85 °C (-76 °F to +185 °F) with low self-discharge, making it suitable for long-term deployment in harsh environments.

Which existing Tadiran or Saft models can directly replace this AA-size 3.6 V cell?

Direct cross-references include Tadiran TL-4903, TL-5903, TL-2100 and Saft LS-14500, LS-14500C, LS33600, all sharing the same ER14505 form factor and axial-lead termination.
