Lithium Thionyl Chloride Battery SAFT LS17500 3.6V 3600mAh

SAFT LS17500 is a primary lithium thionyl chloride (Li-SOCl2) cylindrical battery with a nominal voltage of 3.6V and rated capacity of 3600mAh. Designed for long-term, low-drain applications, this cell offers stable voltage output, low self-discharge and extended shelf life. The chemistry and construction provide reliable performance across a wide operating temperature range, making the battery suitable for utility metering, memory backup, remote sensors and other equipment where long unattended operation is required.

Advantages

The LS17500 delivers high energy density and low self-discharge, enabling multi-year service life in low-current applications. Its stable voltage profile supports sensitive electronics and data retention circuits. The cell’s wide temperature tolerance and robust hermetic construction reduce performance degradation in harsh environments. Its cylindrical format simplifies replacement and integration into existing housings without the need for complex adapters.

Suitable for

• Utility meters (water, gas, electricity)
• Memory backup for industrial controllers and data loggers
• Remote tracking and telemetry devices
• Wireless sensors and alarm systems
• Portable measurement and monitoring equipment

Key specifications

• Chemistry: lithium thionyl chloride (Li-SOCl2)
• Nominal voltage: 3.6 V
• Typical capacity: 3600 mAh (at specified discharge conditions)
• Cell format: cylindrical
• Operating temperature range: wide temperature tolerance suitable for outdoor and industrial use
• Self-discharge: low self-discharge for long shelf life

How to use

Install the LS17500 in the device following the manufacturer’s polarity markings and recommended holder or contact design. Use within the device’s specified current draw to achieve the expected service life; this battery is optimized for low to moderate continuous or intermittent currents rather than high-drain loads. Store unused cells in a cool, dry place away from direct heat and sunlight. Dispose of used batteries according to local regulations for lithium primary cells or return them to appropriate recycling or collection programs.

Usage recommendations

For longest operational life, design the host device to minimize standby and peak currents, use proper voltage monitoring and avoid continuous high-current pulses. Verify compatibility of voltage and cell dimensions with the product design before deployment.
