Product Overview

The Saft LSH20 is a high‑power 3.6V Lithium Thionyl Chloride (Li‑SOCl₂) primary cell engineered for demanding industrial, military, and aerospace applications that require strong pulse currents, high‑rate discharge capability, and reliable operation across extreme temperatures. Its spiral‑wound construction and Li‑SOCl₂ chemistry make it one of the most widely used high‑power cells in mission‑critical systems where instant activation, rugged durability, and long‑term stability are essential.

Chemistry Profile: Li‑SOCl₂ for High‑Power, Harsh‑Environment Performance

The LSH20 uses Lithium Thionyl Chloride (Li‑SOCl₂) chemistry, chosen for its combination of high energy density, excellent voltage stability, and strong high‑rate capability. Key characteristics of this chemistry include:

• 3.6V nominal output with stable voltage under load

• High pulse capability due to spiral construction

• Very wide operating temperature range, typically −60°C to +85°C

• Low self‑discharge, supporting multi‑year deployments

• Strong cold‑temperature performance, ideal for outdoor and aerospace use

This chemistry enables the LSH20 to deliver both instantaneous high current and long‑term reliability in harsh or remote environments.

Electrical Performance for High‑Drain Applications

The LSH20 is optimized for pulse‑intensive and high‑drain workloads, making it suitable for devices that must activate instantly and deliver consistent power. Its performance profile includes:

• Strong pulse output for RF transmissions, telemetry, and communication systems

• High continuous discharge capability for active electronics

• Stable 3.6V voltage even under heavy load

• Reliable operation in extreme cold and heat

• Long storage life with minimal voltage degradation

This makes the LSH20 a dependable choice for systems requiring immediate responsiveness and consistent high‑rate power delivery.

Mechanical and Environmental Durability

The LSH20 is built to withstand the toughest industrial and defense environments:

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

• High resistance to shock, vibration, and mechanical stress

• Wide temperature tolerance for aerospace, defense, and remote deployments

• Integrated safety vent for controlled pressure management

• Long shelf life suitable for extended standby or storage

These features ensure stable performance even in mission‑critical or remote installations where reliability is non‑negotiable.

Typical Applications

The LSH20 is widely used in sectors that require high‑rate discharge, rugged construction, and long‑term reliability:

• Military radios, beacons, and encrypted communication devices

• Aerospace emergency systems and avionics modules

• High‑power industrial IoT sensors and wireless instrumentation

• Electromechanical actuators and control systems

• Oil & gas instrumentation and pipeline monitoring

• Security and intrusion detection systems

• Remote telemetry, SCADA, and environmental monitoring

• Emergency backup and fail‑safe power modules

These systems benefit from the LSH20’s ability to deliver instantaneous current while maintaining stable performance over long service intervals.

Why Engineers Choose the LSH20

• High‑power Li‑SOCl₂ chemistry with strong pulse capability

• Stable 3.6V output under heavy load

• Excellent cold‑weather and extreme‑temperature performance

• Rugged stainless‑steel construction for harsh environments

• Predictable safety behavior with controlled venting

• Maintenance‑free operation for sealed or remote systems

The LSH20 is often selected when designers need a high‑power primary lithium cell capable of long‑term reliability in extreme conditions.
