Lithium Thionyl Chloride Battery SAFT 14250 — single cell, 3.6V, cylindrical

SAFT 14250 is a single-cell lithium thionyl chloride (Li-SOCl2) battery delivering a nominal voltage of 3.6 V in a cylindrical 14250 format. Designed for long-term operation in low-to-medium drain applications, it offers stable discharge voltage, low self-discharge and long shelf life suitable for devices that require reliable primary power over extended periods. The cell is intended for memory backup, metering, security sensors and industrial instrumentation where infrequent but dependable energy delivery is needed.

Advantages

This Li-SOCl2 chemistry provides a high energy density and very low self-discharge, which results in long operational lifetime in standby and intermittent-use devices. The cell maintains a stable nominal voltage under typical load conditions and performs well over a wide temperature range. Its cylindrical 14250 form factor makes it easy to integrate into equipment designed for replaceable primary cells, and the construction supports reliable performance in applications requiring long-term retention of charge.

Suitable for

• Memory backup for electronic modules and data loggers
• Utility metering (gas, water, electricity) with long service intervals
• Passive and active security sensors and alarm systems
• Industrial instrumentation and remote monitoring devices
• IoT nodes and telemetry equipment with low-to-medium pulse loads

Key specifications

• Cell chemistry: lithium thionyl chloride (Li-SOCl2)
• Nominal voltage: 3.6 V
• Cell format: cylindrical 14250 size
• Intended discharge profile: low-to-medium continuous or pulse drains
• Low self-discharge for extended shelf life
• Operating temperature range suitable for environmental and industrial use

How to use

Install the SAFT 14250 cell into the device following the manufacturer’s polarity markings and housing instructions. Use in equipment designed for primary (non-rechargeable) lithium cells and avoid attempts to recharge. For devices with intermittent or periodic transmission, verify that pulse currents remain within the device’s recommended limits for primary Li-SOCl2 cells. Store unused cells in a cool, dry place and insert them shortly before commissioning to maximize service life.

Usage recommendations

Do not expose the cell to fire, high temperatures, or mechanical abuse. Observe device-specific current limits and cut-off voltages to prevent premature depletion. Dispose of used cells in accordance with local regulations for lithium batteries and battery recycling.
