Li-SO2 primary battery system
BA 5847 B/U
Assembled from 2 LO 26 SX cells
connected in series.
Key features
• A non-replaceable fuse is
incorporated in the negative leg.
• A normally closed thermal fuse
(TCO) is incorporated in the
battery. It is non-replaceable
and non-resetable.
• A diode is incorporated to
prevent charging or flow of
current into the battery.
