Product Overview

The Saft M 19 is a compact, high‑reliability Lithium Manganese Dioxide (Li‑MnO₂) primary cell engineered for long‑life, moderate‑drain industrial and IoT applications that require stable voltage, dependable pulse capability, and rugged performance in harsh environments. With its 3.0V nominal output, stainless‑steel construction, and excellent intrinsic safety, the M 19 is widely used in sensors, metering, defense electronics, medical devices, and tracking systems where maintenance‑free operation is essential.

Performance Characteristics of Li‑MnO₂ Chemistry

The M 19 uses Li‑MnO₂ chemistry, which provides a balanced performance profile ideal for compact devices that need both long‑term energy and intermittent high‑current bursts. This chemistry offers:

• High pulse capability without external capacitors

• Stable 3.0V output across most of the discharge curve

• Excellent intrinsic safety due to the stable Li‑MnO₂ system

• Good performance at moderate discharge rates

• Wide operating temperature range, typically −40°C to +70°C

• Low self‑discharge enabling multi‑year deployments

These characteristics make the M 19 a strong choice for electronics that must operate reliably in remote, sealed, or harsh environments.

Key Technical Advantages

The Saft M 19 is engineered to deliver consistent performance in compact, long‑life industrial systems:

• Compact cylindrical format optimized for space‑constrained designs

• Reliable pulse performance for RF transmissions, sensing, and telemetry

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

• Non‑pressurized, non‑flammable design for enhanced safety

• Long shelf life with minimal voltage drop during storage

• High energy density relative to its size

This combination supports both continuous low‑drain operation and periodic high‑drain events without compromising longevity.

Common Applications for the Saft M 19

The M 19 is widely used across industries that require long‑term, maintenance‑free power in compact devices:

• Utility metering (AMR/AMI)

• Industrial IoT sensors and wireless modules

• Defense and aerospace electronics

• Medical and diagnostic equipment

• Asset tracking and geolocation systems

• Security and intrusion detection devices

• Automotive telematics and embedded systems

• Environmental and agricultural monitoring networks

These applications benefit from the M 19’s ability to deliver stable voltage and dependable pulse performance over long operational lifetimes.

Why Engineers and OEMs Choose the M 19

• High pulse capability for RF and sensor‑driven workloads

• Stable 3.0V output for sensitive electronics

• Low self‑discharge for long‑term storage and deployment

• Wide temperature tolerance for harsh industrial environments

• Proven reliability in mission‑critical systems

• Maintenance‑free operation for sealed or remote devices

The M 19 is often selected when designers need a compact, safe, and pulse‑capable Li‑MnO₂ power source that can operate reliably for years without maintenance.
