Saft LSH20: High-Power Battery for Extreme Environments

Introduction to the Saft LSH20

The Saft LSH20 is a 3.6V D-size primary lithium-thionyl chloride (Li-SOCl₂) battery designed for high-power applications in the most demanding environments. With a robust capacity of 13000mAh, this battery is engineered to deliver exceptional performance for industries like oil and gas, aerospace, and industrial automation. Its spiral construction and ability to handle high current pulses make it a powerhouse for applications requiring both reliability and power.

Key Features of the Saft LSH20

The LSH20 utilizes lithium-thionyl chloride chemistry to provide a high nominal voltage of 3.6V, ensuring stable power delivery even under heavy loads. Unlike bobbin-style batteries, the LSH20’s spiral construction is optimized for high-power output, capable of delivering pulses up to 4A. This makes it ideal for applications requiring sudden bursts of energy, such as in drilling equipment or emergency systems.

The battery’s low self-discharge rate, less than 1% per year at 20°C, ensures it retains its charge during long periods of inactivity, making it suitable for backup power or remote applications. Its ability to operate in extreme temperatures, from -60°C to +150°C, sets it apart as a reliable choice for harsh environments like oil rigs or aerospace systems.

Construction and Design

The LSH20 is built with a stainless steel container and a hermetic glass-to-metal seal, offering superior resistance to corrosion and environmental stress. Its non-flammable electrolyte enhances safety, while the low magnetic signature makes it suitable for sensitive applications. With dimensions of 33.4mm x 61.6mm and a weight of approximately 100g, the LSH20 is robust yet manageable for industrial applications.

Applications of the Saft LSH20
