Product Overview

The Saft M 56 is a rugged, high‑performance Lithium Manganese Dioxide (Li‑MnO₂) primary cell engineered for mission‑critical applications that demand stable voltage, strong pulse capability, and long‑term reliability. Designed for compact devices operating in harsh or unpredictable environments, the M 56 delivers dependable 3.0V power with excellent safety characteristics and multi‑year endurance.

Performance Profile of Li‑MnO₂ Chemistry

The M 56 leverages Li‑MnO₂ chemistry, which is optimized for applications requiring both long‑life energy delivery and intermittent high‑current pulses. This chemistry provides:

• High pulse capability suitable for RF, telemetry, and sensor activation

• Stable 3.0V output across most of the discharge curve

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

• Strong performance at moderate to high discharge rates

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

• Low self‑discharge for multi‑year deployments

This makes the M 56 ideal for compact devices that must operate reliably in remote, sealed, or extreme environments.

Key Technical Advantages

The Saft M 56 is engineered to deliver consistent performance in demanding industrial and defense‑grade applications:

• Compact cylindrical format optimized for space‑constrained designs

• Reliable pulse performance without requiring external capacitors

• Hermetically sealed construction 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 stress

These characteristics allow the M 56 to support both continuous low‑drain operation and periodic high‑drain events without compromising longevity.

Common Applications for the Saft M 56

The M 56 is widely used across industries where compact size, long‑term reliability, and pulse capability are essential:

• Utility metering (AMR/AMI)

• Industrial IoT sensors and wireless modules

• 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 56’s ability to deliver stable voltage and dependable pulse performance over long operational lifetimes.

Why Engineers and OEMs Choose the Saft M 56

• 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 and military environments

• Proven reliability in mission‑critical systems

• Maintenance‑free operation for sealed or remote devices

The M 56 is often selected when designers need a compact, safe, and pulse‑capable Li‑MnO₂ power source that can operate for years without maintenance.
