Tadiran TL-5276/W 3.6V 1.0Ah lithium battery 2-pin connector
A 3.6 V 1.0 Ah lithium thionyl chloride cell with a 2-pin connector, 10-year shelf life and a -60 °C to +85 °C operating range
- Battery TypeTL-5276
- High operating voltage maintained throughout most of the application lifetime
- 0 Ah nominal capacity among the highest available on the market today
- Less than 1% capacity loss after one year of storage at 20°C
- Operates reliably from -60°C to +85°C in harsh environments
- Non-flammable inorganic electrolyte with low magnetic signature for sensitive equipment
Tadiran TL-5276/W Lithium Thionyl Chloride Battery
The Tadiran TL-5276/W is a 3.6V 1.0Ah primary lithium thionyl chloride cell fitted with a 2-pin connector. It delivers a high, stable operating voltage and very low self-discharge, losing less than one percent of capacity per year at 20°C. The inorganic electrolyte is non-flammable and non-pressurised at ambient temperature. A shelf life exceeding ten years supports long-term spares holding.
Suited for low-current industrial
This cell suits equipment that draws continuous currents up to 50mA and occasional pulses up to 100mA, such as memory-backup circuits, remote sensors, and tracking beacons. The wide operating range from -60°C to +85°C fits harsh outdoor and avionics environments. Buyers needing rechargeable chemistry or higher continuous current should look at other technologies.
3.6V 1.0Ah Li-SOCl2 chemistry with 2-pin termination
The lithium thionyl chloride chemistry provides the high energy density and voltage stability required for long-life, low-drain applications. The 2-pin connector matches the listed compatible part numbers including TL-5276/W, B9574T, and LS14250MLB. The cell is not rechargeable; charging attempts create a safety hazard. Store in a clean, cool, dry area not exceeding 30°C.

Questions about this item
How do I connect the 2-pin connector, and which step is commonly reversed?
Match the connector polarity to the device socket before pressing it in; the step often reversed is plugging it in backwards, which prevents the 3.6 V supply from reaching the load.
What replacement will this lithium thionyl chloride cell need after its service life?
The cell is non-rechargeable, so after the 1.0 Ah capacity is depleted you must replace it with another TL-5276/W or compatible 3.6 V 1.0 Ah pack such as the LS14250MLB.
What limit appears first when the battery runs continuously at its 50 mA maximum?
The 1.0 Ah capacity is exhausted after roughly 20 hours at the 50 mA continuous rating, so runtime is the first limit under sustained use.
