M20HR

## M 20 HR 2 cell Primary Li-MnO 

## 3 V high power lithium manganese dioxide D-size spiral cell 

Saft’s M 20 HR cell is ideally suited for applications requiring high discharge, continuous or pulse power with stable voltage under high discharge in - 40°C / + 72°C environment. 

## 

- High drain / high pulse capability 

- High voltage response, stable during most of the lifetime of the application even after long dormant periods 

- High capacity at high current and low temperature 

- Low self-discharge compatible with long operating life (less than 1% after 1 year of storage at + 20°C) 

- Superior resistance to corrosion 

- ■ Low magnetic signature 

## Key features 

- Spiral construction 

- Hermetic construction with glass-to-metal seal 

- Stainless steel container 

- Integrated safety vent 

- Non-corrosive electrolyte 

- Non-pressurized at room temperature 

- ■ Restricted for transport (Class 9) ■ Made in Germany 

Designed to meet all major quality, safety and environmental standards 

- Safety: UL 1642 (File MH 61234), IEC 60086-4 

- Transport: UN 3090 and UN 3091 

- ■ Military: VG96915 part 2 and part 154 

- Quality: ISO 9001, Saft World Class Continuous program 

- ■ Environment: ISO 14001

- (1) Dependent upon current drain, temperature and cut-off. 

## Typical applications 

- Radio communications 

- Alarms and security systems 

- ■ ELTs, EPIRBs ■ Tracking systems ■ M2M communication ■ Medical devices ■ Oil & gas applications 

(2) Dependent upon pulse characteristics, temperature, cell history and application. Higher rates are available under certain circumstances 

(3) To maintain cell heating within safe limits. Battery packs may imply lower level of maximum current and may request specific thermal protection. Consult Saft. 

(4) Operating temperatures up to + 85°C can be achieved. Consult Saft. 

- (5) Long time storage at high temperature may affect performances. Consult Saft.
