Primary lithium battery system
BA 5598/U and BA 5598 A/U
15 V/3 V Primary lithium sulfur dioxide (Li-SO2) battery
The battery consists of 5 LO25SX cells
connected in series with a tap at one cell
providing an overall section of 15 V with a
3 V tap open circuit voltage.
Key Features
■■ A non-replaceable 3 A fuse is
incorporated in both the ground and
3 V outputs
■■ A normally closed high temperature
one-shot thermal fuse is incorporated
on the ground output
■■ A diode is incorporated on into the
overall 15 V positive output
■■ A constant discharge device (CDD)
consisting of a manually activated pull
tab and resistor is incorporated to
permit discharge of the battery to 0 V
for disposal
■■ Alternative configurations such as no
CDD are available. Consult factory.
Typical applications
■■ AN/PRC-25
■■ AN/PRC-77
■■ AN/PRC-74
■■ AN/PRD-11
■■ TSEC/KY-38
■■ TSEC/KY-65
■■ AN/GRQ-26
■■ AN/RRD-10
■■ AN/GRA-114
■■ AN/MSC-25
