Product Overview

The Saft M 19 HR is a compact, high‑rate Lithium Manganese Dioxide (Li‑MnO₂) primary cell engineered for industrial, military, and IoT applications that require strong continuous currents, reliable pulse performance, and long‑term stability in harsh environments. With its 3.0V nominal output, stainless‑steel construction, and excellent intrinsic safety, the M 19 HR is ideal for compact devices that must operate for years without maintenance while supporting higher‑drain electronics.

High‑Rate Li‑MnO₂ Chemistry for Demanding Loads

The M 19 HR belongs to Saft’s high‑rate (HR) series, designed specifically for applications that draw higher continuous current than standard Li‑MnO₂ cells can support. Its chemistry and internal design deliver:

• High continuous discharge capability for active electronics

• Strong pulse performance for RF transmissions, telemetry, and sensor bursts

• Stable 3.0V output even under elevated loads

• Excellent intrinsic safety with a non‑pressurized, non‑flammable design

• Reliable operation at moderate to high discharge rates

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

• Low self‑discharge, enabling multi‑year deployments

This chemistry makes the M 19 HR a strong fit for compact devices that require both endurance and high‑rate performance.

Key Technical Characteristics

The Saft M 19 HR is engineered for consistent, long‑term performance in demanding industrial systems:

• Compact cylindrical format optimized for space‑constrained designs

• High‑rate discharge capability for active sensors, RF modules, and electronics

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

• Long shelf life with minimal voltage drop during storage

• High energy density relative to its size

• Strong mechanical robustness for vibration, shock, and thermal cycling

These characteristics allow the M 19 HR to support both continuous high‑drain operation and periodic high‑pulse events without compromising longevity.

Common Applications for the Saft M 19 HR

The M 19 HR is widely used across industries where high‑rate discharge, compact size, and long‑term reliability are essential:

• Industrial IoT sensors and wireless communication modules

• Utility metering (AMR/AMI) with high‑drain communication bursts

• Defense and aerospace electronics

• Medical and diagnostic devices

• Asset tracking and geolocation systems

• Security and intrusion detection equipment

• Automotive telematics and embedded systems

• Environmental and agricultural monitoring networks

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

Why Engineers and OEMs Choose the M 19 HR

• High‑rate discharge capability for demanding electronics

• Stable 3.0V output for sensitive circuits

• Low self‑discharge for multi‑year deployments

• Wide temperature tolerance for harsh industrial environments

• Proven reliability in mission‑critical systems

• Maintenance‑free operation for sealed or remote devices

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