Lithium Battery Information Sheet
Product Overview
The Saft LO39SHX is a high‑power primary lithium cell engineered for applications that demand instantaneous pulse current, stable voltage under heavy load, and reliable operation across extreme temperatures. Built on a Li‑SO₂ system, it delivers the high‑rate capability, cold‑temperature performance, and intrinsic safety required in military, aerospace, industrial, and emergency‑response electronics.
High‑Power Electrical Performance
The LO39SHX 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 construction 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 LO39SHX 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 LO39SHX 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
-
