Tadiran

Tadiran TL-4903/S 3.6V AA 2.4 Ah lithium battery

SKU CH-M67Q-SQZYE

AA lithium thionyl chloride cell delivering 3.6 V and 2.4 Ah with a ten-year shelf life and operation from –60 °C to +85 °C

  • High 3.6 V output voltage maintained across most of the battery life
  • 4 Ah capacity among the highest available in AA lithium cells
  • Shelf life exceeds 10 years with under 1 % annual self-discharge
  • Operates reliably from -60 °C to +85 °C in harsh environments
  • Non-flammable inorganic electrolyte enhances safety in critical applications

Tadiran TL-4903/S 3.6 V AA lithium cell

The Tadiran TL-4903/S is a primary lithium thionyl chloride cell in AA size that delivers 3.6 V and 2.4 Ah. It suits metering, alarm, tracking and industrial IoT devices that need long-term, maintenance-free power.

Replaces earlier ER14505-type cells

The cell is compatible with Tadiran TL-2100, TL-5903, TL-5104, Saft LS-14500, LS-14500C and LS33600, Sonnenschein SL-360/S and SL-760/S, Maxell ER6S-TC, Minamoto ER14505, Xeno XL-060F and ER6, XL-060F, SB-AA11 and PT-2100. The jump is worthwhile when an application demands the higher 2.4 Ah capacity and the stable voltage profile of this chemistry.

Not for rechargeable or high-drain uses

The battery is not rechargeable and must never be placed in a charger. Maximum recommended continuous current is 60 mA with a 120 mA pulse limit, so it cannot drive motors, bright LEDs or wireless transmitters that draw more. Operating range spans -60 °C to +85 °C with less than 1 % yearly self-discharge at 20 °C.

Questions about this item

What are the exact diameter and height so I can confirm it fits my AA slot?

The cell measures 14.5 mm in diameter and 50.5 mm in height, matching the standard AA form factor with a button-top termination.

Is there any preparation needed before first use, or can I install it straight away?

Insert the battery with the button top facing the positive contact; no charging or priming is required because the chemistry is primary lithium thionyl chloride and non-rechargeable.

After how many years in storage should I plan to replace it?

Shelf life exceeds 10 years with less than 1 % capacity loss per year at 20 °C, so plan replacement around the 10-year mark.
