Tadiran TL-2150/S 3.6V 1/2 AA Lithium Battery
This 1/2 AA lithium thionyl chloride cell delivers 3.6 volts and 1 Ah capacity for long-life, low-current applications. It suits metering, security, tracking and industrial sensors that need reliable energy for years without replacement. The button-top termination fits standard holders used in these devices. Buyers who need a rechargeable cell or higher continuous current for motors or radios should look elsewhere.
Thermals noise and power draw
The chemistry operates from -60°C to +85°C with stable voltage through most of its service life. Self-discharge stays below 1% per year at 20°C, so stored spares retain charge for a decade or more. Continuous current is rated at 50 mA with pulse capability up to 100 mA. The inorganic electrolyte is non-flammable and non-pressurised at ambient temperature.
Bundled accessories and software
No accessories, cables or software are included with the cell. The data lists compatible alternatives such as Tadiran TL-4902, TL-5101, TL-5902, TL-5111, Saft LS-14250 and LS-14250c, Toshiba ER3v, and Sonnenschein SL-350/S, SL-750/S and SL-150/S 14250 for cross-reference only. The battery is not rechargeable; do not attempt to recharge it.

Questions about this item
How do I install the Tadiran TL-2150/S button-top battery and what orientation step is often missed?
Insert the battery with the button top facing the positive contact; the 14.5 mm diameter and 25.2 mm height must match the holder exactly, or the cell will not seat.
What maintenance or replacement will the TL-2150/S need after long-term deployment?
The cell is non-rechargeable; after 10+ years shelf life or when voltage drops under load, replace it with another ER14250-compatible lithium thionyl chloride unit.
What sustained-current limit appears first when the TL-2150/S powers a continuous load?
The maximum recommended continuous current is 50 mA; exceeding this reduces capacity and can trigger early voltage sag.
