Lithium Battery Information Sheet
Product Overview
The Saft LO26SX is a high‑power primary lithium cell engineered for applications that require instantaneous pulse current, stable voltage under heavy load, and reliable operation across extreme temperatures. As part of Saft’s LO‑series, it uses Lithium Sulfur Dioxide (Li‑SO₂) chemistry, which provides strong high‑rate discharge capability, excellent cold‑temperature performance, and predictable safety behavior. The LO26SX is widely deployed in military, aerospace, industrial, and emergency‑response systems where ruggedness and long‑term reliability are essential.
High‑Power Electrical Performance
The LO26SX is optimized for fast‑response, high‑drain workloads, making it ideal for devices that must activate instantly and deliver strong bursts of power. Its spiral‑wound internal design supports:
-
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 LO26SX a dependable choice for systems requiring immediate responsiveness and consistent high‑rate power delivery.
Chemistry Profile: Li‑SO₂ for High‑Rate, Harsh‑Environment Use
The LO26SX uses Li‑SO₂ chemistry, selected for its ability to support:
-
High‑rate discharge and strong pulse currents
-
Stable voltage under demanding electrical loads
-
Excellent cold‑temperature performance
-
Controlled venting and predictable safety characteristics
This chemistry is well‑suited for defense and industrial systems where power delivery and safety are top priorities.
Mechanical and Environmental Durability
The LO26SX is built for environments where ruggedness and reliability are non‑negotiable:
-
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 LO26SX 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 LO26SX’s ability to deliver instantaneous current while maintaining stable performance over long service intervals.
Why Engineers Choose the LO26SX
-
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 LO26SX is often selected when designers need a high‑power primary lithium cell capable of long‑term reliability in extreme conditions.
