Primary Li-MnO2 battery
MIRA battery
30 V lithium manganese dioxide (Li-MnO2) battery
Saft’s MIRA battery is used as power
source for the MIRA night vision system,
which is a part of the missile system
MILAN. It is also suitable for other
military and civil applications with high
 High drain and pulse capability
 High voltage response, stable even
after long dormant periods
 No voltage delay
 Low self-discharge compatible with
long shelf-life of 10+ years (less than
1% after 1 year of storage at + 20 °C)
High energy density
Superior resistance to corrosion
Key features
 Twenty M 19 HR cells with spiral
design in 10S2P configuration
Safe, hermetic and non-pressurized
stainless steel cell construction with
glass-to-metal seal and safety vent
Integrated state-of-charge indicator
with LED display and push button
Short-circuit proof due to integrated
Charge protection diode
Restricted for transport (class 9)
