Product Overview

The Saft LS33600 is a high‑energy 3.6V Lithium Thionyl Chloride (Li‑SOCl₂) primary cell engineered for ultra‑long‑life, low‑drain, and moderate‑pulse applications. As one of the largest cylindrical cells in Saft’s LS‑series, it delivers exceptional energy density, very low self‑discharge, and multi‑decade operating life, making it a leading choice for industrial, metering, and remote‑monitoring systems that require maintenance‑free power.

High‑Energy Li‑SOCl₂ Chemistry

The LS33600 uses Li‑SOCl₂ chemistry, optimized for long‑duration, low‑drain applications where energy density and shelf life matter more than high‑rate discharge. Key chemical advantages include:

• 3.6V nominal output with excellent voltage stability

• Very high energy density, among the highest of any primary lithium chemistry

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

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

• Long shelf and operational life, frequently exceeding 10–20 years

This chemistry makes the LS33600 ideal for long‑term autonomous systems where battery replacement is difficult or impossible.

Electrical Performance for Long‑Life, Low‑Drain Systems

The LS33600 is engineered for low‑to‑moderate continuous currents with the ability to handle occasional pulse loads when paired with a capacitor or hybrid layer capacitor (HLC). Performance characteristics include:

• Stable 3.6V output for low‑drain electronics

• High energy capacity for multi‑year or multi‑decade deployments

• Ability to support moderate pulses with appropriate buffering

• Reliable operation in extreme cold and heat

• Minimal voltage drop during long‑term standby

This makes the LS33600 a dependable choice for systems requiring long‑duration, maintenance‑free power.

Mechanical and Environmental Durability

The LS33600 is built for harsh 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 remote or exposed 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 LS33600 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 LS33600’s ability to deliver decade‑long performance with minimal maintenance.

Why Engineers Choose the LS33600

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

• High energy density for multi‑year or multi‑decade deployments

• 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 LS33600 is often selected when designers need a high‑energy, long‑life primary lithium cell capable of powering autonomous devices for years or decades.
