Product Overview

The Saft LSH20‑HTS is a specialized high‑power 3.6V Lithium Thionyl Chloride (Li‑SOCl₂) primary cell engineered for high‑temperature environments, strong pulse currents, and reliable long‑term operation in mission‑critical systems. As a high‑temperature variant of the standard LSH20, the LSH20‑HTS is designed for continuous operation in elevated thermal conditions where conventional Li‑SOCl₂ cells cannot maintain performance or safety margins.

This makes the LSH20‑HTS a preferred choice for oil & gas, defense, aerospace, and industrial IoT deployments where heat, vibration, and high‑rate discharge are unavoidable.

High‑Temperature Chemistry Profile: Li‑SOCl₂ Optimized for Thermal Stability

The LSH20‑HTS uses a high‑temperature‑stabilized Li‑SOCl₂ chemistry, engineered to maintain voltage stability, safety, and pulse capability under elevated thermal loads. Key characteristics include:

• 3.6V nominal output with stable voltage at high temperatures

• Enhanced electrolyte formulation for thermal stability

• High pulse current capability from spiral‑wound construction

• Extended operating range, typically up to +150°C depending on configuration

• Low self‑discharge, even in elevated‑temperature standby conditions

• Strong cold‑temperature performance, maintaining versatility across environments

This chemistry enables the LSH20‑HTS to deliver high‑rate power in environments where standard Li‑SOCl₂ cells would degrade or fail.

Electrical Performance in High‑Temperature, High‑Drain Applications

The LSH20‑HTS is optimized for pulse‑intensive, high‑drain workloads that must operate reliably in extreme heat. Performance advantages include:

• Strong pulse output for RF transmissions, telemetry, and high‑power electronics

• Stable 3.6V voltage under heavy load and high ambient temperatures

• High continuous discharge capability for active systems

• Reliable operation in both high‑heat and low‑temperature environments

• Long operational life with minimal voltage drift

This makes the LSH20‑HTS ideal for downhole tools, military electronics, and industrial systems exposed to sustained heat.

Mechanical and Environmental Durability

The LSH20‑HTS is engineered for harsh, high‑temperature industrial and defense environments:

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

• High resistance to shock, vibration, and mechanical stress

• Specialized internal components rated for elevated thermal exposure

• Integrated safety vent for controlled pressure management

• Long shelf life, even in warm storage conditions

These features ensure stable performance in mission‑critical, high‑heat, and remote installations.

Typical Applications

The LSH20‑HTS is widely used in sectors that require high‑rate discharge, thermal resilience, and long‑term reliability:

• Oil & gas downhole tools, MWD/LWD systems

• High‑temperature industrial IoT sensors

• Military radios, beacons, and encrypted communication systems

• Aerospace emergency modules and avionics

• High‑heat electromechanical actuators and control systems

• Pipeline monitoring and high‑temperature SCADA nodes

• Emergency backup and fail‑safe power modules in hot environments

These systems benefit from the LSH20‑HTS’s ability to deliver instantaneous current while maintaining stability under extreme thermal stress.

Why Engineers Choose the LSH20‑HTS

• High‑temperature‑rated Li‑SOCl₂ chemistry

• Strong pulse and high‑rate discharge capability

• Stable 3.6V output under heavy load and elevated temperatures

• Rugged stainless‑steel construction for harsh environments

• Predictable safety behavior with controlled venting

• Maintenance‑free operation for sealed or remote systems

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