- Compact 1/2 AA size fits space-constrained devices at 14.5mm diameter
Tadiran TL-5101/S 3.6V 1/2 AA Lithium Battery
The Tadiran TL-5101/S is a 3.6V 1/2 AA lithium thionyl chloride primary cell delivering 950 mAh capacity. It uses a button-top termination and measures 14.5 mm diameter by 25.2 mm height. The chemistry provides a high, stable operating voltage and a shelf life exceeding 10 years with very low self-discharge.
Suits long-life low-drain devices.
This cell suits metering, alarm, tracking and industrial sensors that require multi-year operation from -60°C to +85°C. It is not for devices needing rechargeable batteries or higher continuous current than the chemistry can sustain. Buyers who want a rechargeable power source should look at something else.
950 mAh capacity at 3.6V defines the energy budget
The single specification that decides fit is the 950 mAh capacity at 3.6V, which sets the total energy available for the application. Verify the device voltage window and average current draw against this rating. The ER14250 form factor and button top must also match the holder.

Questions about this item
What comes in the box and does it need any extra hardware?
The package contains the single Tadiran TL-5101/S cell with button-top termination. No charger or holder is included because the chemistry is non-rechargeable and the cell is designed to be soldered or clipped directly into the host device.
How do I decide between the listed compatible models such as TL-4902 or Saft LS-14250?
All listed models share the 14.5 mm diameter, 25.2 mm height, 3.6 V nominal voltage and 950 mAh capacity, so they are electrically and mechanically interchangeable; choose the one your equipment manual specifies or the one most readily available.
What does the 950 mAh rating actually deliver in a device running at 3.6 V?
At the rated 3.6 V the cell can supply 950 mAh of charge, which translates to roughly 3.4 Wh of energy; the stable voltage plateau means the device sees near-constant voltage through most of the discharge, and the low self-discharge preserves capacity for 10+ years in storage.
