Product Overview

The Saft LS14500 is a high‑energy 3.6V Lithium Thionyl Chloride (Li‑SOCl₂) primary cell built for long‑duration, low‑drain, and moderate‑pulse applications where reliability, compact size, and multi‑year autonomy are essential. As the AA‑size member of Saft’s LS‑series, the LS14500 delivers excellent energy density, very low self‑discharge, and stable voltage, making it one of the most widely used industrial lithium cells for IoT, metering, and remote‑monitoring systems.

High‑Energy Li‑SOCl₂ Chemistry

The LS14500 uses Li‑SOCl₂ chemistry, optimized for long‑life, low‑drain operation. Key characteristics include:

• 3.6V nominal output with stable voltage throughout discharge

• High energy density in a standard AA form factor

• Extremely low self‑discharge, typically under 1% per year

• Wide operating temperature range, often −60°C to +85°C

• Operational life of 10–20 years, depending on load profile

This chemistry is ideal for autonomous devices deployed in remote or inaccessible locations where battery replacement is costly or impractical.

Electrical Performance for Long‑Life, Low‑Drain Systems

The LS14500 is engineered for low continuous currents with the ability to support moderate pulse loads when paired with a capacitor or hybrid layer capacitor (HLC). Performance advantages include:

• Stable 3.6V output for low‑drain electronics

• High energy capacity for multi‑year deployments

• Ability to support moderate pulses with proper buffering

• Reliable operation in extreme cold and heat

• Minimal voltage drop during long‑term standby

This makes the LS14500 a dependable choice for systems requiring decade‑long, maintenance‑free operation.

Mechanical and Environmental Durability

The LS14500 is built for rugged industrial and outdoor environments:

• Hermetically sealed stainless‑steel housing for leak‑proof operation

• High resistance to shock, vibration, and mechanical stress

• Wide temperature tolerance for exposed or remote installations

• Integrated safety vent for controlled pressure management

• Long shelf life suitable for extended storage or standby

These features ensure stable performance in mission‑critical or remote deployments.

Typical Applications

The LS14500 is widely used in sectors that require long‑life, low‑drain power with occasional pulse demands:

• Utility metering (gas, water, heat meters)

• Industrial IoT sensors and wireless modules

• Smart city infrastructure and environmental monitoring

• Asset tracking and geolocation beacons

• Oil & gas instrumentation and pipeline monitoring

• Security and intrusion detection systems

• SCADA nodes and remote telemetry

• Memory backup and RTC power

These systems benefit from the LS14500’s ability to deliver years of stable, maintenance‑free performance.

Why Engineers Choose the LS14500

• Ultra‑long‑life Li‑SOCl₂ chemistry with extremely low self‑discharge

• High energy density in a compact AA format

• Stable 3.6V output for low‑drain electronics

• Excellent temperature resilience for outdoor and industrial use

• Rugged stainless‑steel construction for harsh environments

• Maintenance‑free operation for sealed or remote systems

The LS14500 is often selected when designers need a compact, long‑life primary lithium cell capable of powering autonomous devices for many years.
