Description

Saft LO29SHX 3.0 Volt Li-SO₂ Button Cell | High-Drain C-Size Lithium Battery

Name: Saft LO29SHX 3.0V Primary Lithium Li-SO₂ Button Cell – High-Drain C-Size Spiral Cell
Brand: Saft
SKU: LO29SHX
Price: 17.25 USD
Availability: InStock

The Saft LO29SHX 3.0V Primary Lithium (Li-SO₂) Battery is a high-performance C-size spiral cell designed for equipment requiring exceptional pulse load performance and long-term reliability. Built to meet stringent military and environmental requirements, the LO29SHX provides stable voltage, low self-discharge, and the ability to operate in extreme temperatures.

Engineered with hermetic glass-to-metal sealing and a built-in safety vent, this high-drain lithium cell offers superior safety and durability, even in rugged field environments. Its Li-SO₂ chemistry delivers strong energy density and rapid current response, making it ideal for radio communications, rescue beacons, sonobuoys, and other high-demand devices.

Made in the USA and UL-recognized, the Saft LO29SHX is widely used as a direct replacement for several military and OEM part numbers, including G52/11 and LO29SHX formats.
