- High 3.6 V voltage stable over lifetime
- 3600 mAh capacity among the highest available
- Operates from -60 °C to +85 °C
- Less than 1 % self-discharge per year
- UL approved with hermetic glass-to-metal seal
What this battery is and who uses it
The SAFT LS17500 is a 3.6 Volt A-size lithium thionyl chloride primary cell rated at 3600 mAh. It is built for equipment that needs a very long service life and a stable voltage across a wide temperature range. Typical applications include utility metering, remote sensors, tracking devices and memory-backup circuits where replacement is difficult or costly.
Who this suits and who should look elsewhere
Engineers designing low-current devices that must operate from -60°C to +85°C will benefit from the low self-discharge rate and hermetic glass-to-metal seal. The cell is not rechargeable and its pulse capability is typically limited to 120 mA, so designers needing higher peak currents or a rechargeable chemistry should select a different power source.
Behaviour under sustained load
The bobbin construction and non-flammable electrolyte keep the nominal voltage near 3.6 V during most of the discharge at 1 mA. Capacity loss during storage is below 1 % per year at +20°C, so the cell retains usable energy after years in the field. Continuous high-current draw is not supported; the chemistry is optimised for steady, low-drain operation over decades.

Questions about this item
What device voltage must match the 3.6 V nominal rating of this SAFT LS17500 cell?
The equipment you power must be designed for a 3.6 V lithium-thionyl-chloride primary cell; the battery delivers 3.6 V at 1 mA load and 3.66 V open-circuit at +20 °C.
Can the 17 mm diameter and 50.9 mm height fit the A-size battery compartment in my existing meter?
Yes — the cell measures 17 mm diameter by 50.9 mm height, the standard A-size envelope, so it fits existing A-size holders.
How do I confirm the battery is healthy after installing it in my logger?
Measure open-circuit voltage with a multimeter; a fresh cell reads about 3.66 V at +20 °C, and voltage should stay near 3.6 V under the logger's typical microamp load.
