Product Overview

The Saft LO43SHX is a high‑power primary lithium cell engineered for applications that require instantaneous pulse current, stable voltage under heavy load, and dependable operation across extreme temperatures. Built on a Li‑SO₂ system, it delivers the high‑rate capability, cold‑temperature performance, and intrinsic safety needed in military, aerospace, industrial, and emergency‑response electronics. As one of the larger and more robust LO‑series cells, the LO43SHX is designed for mission‑critical systems where reliability cannot be compromised.


High‑Power Electrical Performance

The LO43SHX is optimized for fast‑response, high‑drain workloads, supporting devices that must activate instantly and deliver strong bursts of power. Its spiral‑wound construction enables:

  • Strong pulse output for RF transmissions, encrypted radios, and telemetry

  • High continuous discharge capability for active electronics

  • Stable operating voltage under heavy load

  • Reliable performance in low‑temperature environments

  • Multi‑year storage with minimal voltage degradation

This performance profile makes the LO43SHX ideal for systems requiring immediate responsiveness and consistent high‑rate power delivery.


Chemistry Profile: Li‑SO₂ for High‑Rate, Harsh‑Environment Use

The LO43SHX uses Lithium Sulfur Dioxide (Li‑SO₂) chemistry, selected for its ability to support:

  • High‑rate discharge and strong pulse currents

  • Excellent cold‑temperature performance

  • Stable voltage under demanding electrical loads

  • Predictable safety behavior with controlled venting

This chemistry is widely used in defense and industrial systems where power delivery, safety, and reliability are top priorities.


Mechanical and Environmental Durability

The LO43SHX is engineered for environments where ruggedness and reliability are essential:

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

  • High resistance to shock, vibration, and mechanical stress

  • Wide operating temperature range suitable for aerospace, defense, and industrial deployments

  • Integrated safety vent for controlled pressure management

  • Long shelf life for extended standby or storage

These characteristics ensure stable performance even in mission‑critical or remote installations.


Typical Applications

The LO43SHX is widely used in sectors that require high‑rate discharge, rugged construction, and long‑term reliability:

  • Military radios, beacons, and encrypted communication systems

  • Aerospace emergency modules and avionics

  • High‑power industrial IoT sensors

  • Electromechanical actuators and control systems

  • Oil & gas instrumentation and pipeline monitoring

  • Security and intrusion detection systems

  • Remote telemetry and SCADA equipment

  • Emergency backup and fail‑safe power modules

These systems benefit from the LO43SHX’s ability to deliver instantaneous current while maintaining stable performance over long service intervals.


Why Engineers Choose the LO43SHX

  • High‑power Li‑SO₂ chemistry with strong pulse capability

  • Stable voltage delivery 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 LO43SHX is often selected when designers need a high‑power primary lithium cell capable of long‑term reliability in extreme conditions.
