Product Overview

The Saft LSP17330‑20F is a compact, high‑energy Lithium Thionyl Chloride (Li‑SOCl₂) primary cell engineered for industrial, metering, and IoT applications that require multi‑decade operating life, ultra‑low self‑discharge, and a stable 3.6V output. As part of Saft’s LSP (Low Self‑Discharge Spiral) series, the LSP17330‑20F delivers a rare combination of high capacity, excellent pulse performance, and rugged environmental durability, making it ideal for remote, sealed, or mission‑critical systems where battery replacement is costly or impossible.

Chemistry and Performance Profile

The LSP17330‑20F uses Li‑SOCl₂ chemistry, optimized for applications requiring very long operating life and high energy density. This chemistry provides:

• Ultra‑low self‑discharge, typically <1% per year, enabling 10–20+ year deployments

• High energy density for compact device designs

• Stable 3.6V output across most of the discharge curve

• Excellent performance in long‑duration standby applications

• Strong pulse capability when paired with a capacitor or hybrid layer cell

• Wide operating temperature range, typically −60°C to +85°C

• Exceptional storage life with minimal voltage drop

This makes the LSP17330‑20F ideal for devices that must operate unattended for long periods in harsh or remote environments.

Key Technical Characteristics

The Saft LSP17330‑20F is engineered for long‑term reliability in industrial and IoT systems:

• High capacity for extended multi‑year deployments

• Spiral construction for improved pulse performance

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

• High safety margin with non‑pressurized design

• Excellent resistance to shock, vibration, and corrosion

• Long shelf life suitable for long‑term storage and slow‑drain applications

These characteristics support both low‑drain continuous operation and intermittent high‑drain events, depending on system design.

Common Applications for the Saft LSP17330‑20F

The LSP17330‑20F is widely used in long‑life industrial and IoT applications where battery replacement is difficult or impossible:

• Utility metering (AMR/AMI)

• Smart gas and water meters

• Industrial IoT sensors and wireless modules

• Pipeline monitoring and oil & gas instrumentation

• Remote environmental and agricultural sensors

• Asset tracking and geolocation systems

• Security and intrusion detection devices

• Military and aerospace electronics

These applications benefit from the LSP17330‑20F’s ability to deliver stable voltage and extremely long service life.

Why Engineers and OEMs Choose the LSP17330‑20F

• Ultra‑long operating life for 10–20+ year deployments

• High energy density for compact device designs

• Stable 3.6V output for sensitive electronics

• Low self‑discharge ideal for long‑term standby

• Wide temperature tolerance for harsh industrial environments

• Proven reliability in mission‑critical systems

• Maintenance‑free operation for sealed or remote devices

The LSP17330‑20F is often selected when designers need a high‑energy, long‑life Li‑SOCl₂ power source that can operate reliably for a decade or more without maintenance.
