Primary Li-MnO2 battery
SEM 70 battery
18 V lithium manganese dioxide (Li-MnO2) battery
Saft’s SEM 70 battery has a 6S1P
configuration of D size Li-MnO2 cells
type M 20 with spiral electrode design. It
is used as power source for the SEM 70
radio communication transceiver and
features a proven shelf-life of 10+ years.
