Tadiran TL-2100/S 3.6V AA 2.1 Ah Lithium Battery
3.6 V AA lithium-thionyl-chloride cell delivers 2.1 Ah capacity, 120 mA continuous and 200 mA pulse current, operates from –60 °C to +85 °C and retains charge for over 10 years in storage
- 6 V nominal voltage delivers stable power through most of the discharge cycle
- 1 Ah capacity ranks among the highest available in AA lithium thionyl chloride cells
- Operates from -60 °C to +85 °C for reliable performance in extreme environments
- Less than 1 % self-discharge per year enables 10+ year shelf life
- Non-flammable, non-pressurised inorganic electrolyte improves safety in sealed devices
Tadiran 3.6 V AA Lithium Cell
The Tadiran TL-2100/S is a 3.6 V AA lithium thionyl chloride primary cell rated at 2.1 Ah. It delivers a high, stable operating voltage and very low self-discharge, retaining over 99 % of its charge after one year at 20 °C. The button-top termination fits standard AA holders. It is built for long-life, low-drain applications where replacement access is difficult.
Ideal for Remote Sensors and Meters
This cell suits utility meters, alarms, GPS trackers, data loggers and memory-backup circuits that draw continuous currents up to 120 mA and occasional pulses up to 200 mA. It operates from -60 °C to +85 °C and resists humid environments. It is not for devices needing rechargeable cells, higher continuous current or a flat-top terminal. Designers requiring a rechargeable chemistry or currents above 200 mA should select a different power source.
2.1 Ah Non-Rechargeable Lithium Thionyl Chloride
The single deciding specification is the 2.1 Ah capacity combined with a non-rechargeable lithium thionyl chloride chemistry. This fixes the energy budget and rules out any design that expects to recharge the cell in situ. Verify that the load profile stays within the 120 mA continuous and 200 mA pulse limits before specifying this battery.

Questions about this item
How can I confirm the Tadiran TL-2100/S 3.6V AA 2.1 Ah Lithium Battery is performing correctly after installation?
Measure the open-circuit voltage with a multimeter; a fresh cell should read close to 3.6 V. Under a load up to 120 mA continuous or 200 mA pulse the voltage should remain stable, confirming the lithium thionyl chloride chemistry is working as intended.
What is included with the Tadiran TL-2100/S battery and what must be purchased separately?
The package contains the single AA-size ER14505 cell with button-top termination. No holder, leads, charger or additional hardware is supplied; any mounting hardware or protection circuitry required by your application must be sourced separately.
Which capacity version of the Tadiran lithium AA battery should I choose for my device?
This model is offered in a single 2.1 Ah capacity. If your equipment specifies ER14505, TL-2100/S, LS-14500, XL-060F or any of the listed compatible part numbers, this 2.1 Ah cell is the correct version to use.
