8-10. INTRODUCTION.
Maintenance of the battery box consists of replacing defective components. The battery box can be checked as
described in section III. All other components are checked by performing the visual inspection procedures found
in paragraph 8-11. When a bad component is identified, replace it using the procedure in this section.
WARNING
A lithium-sulfur dioxide (Li-S02) battery used with your manpack radio contains pressurized
sulfur dioxide (S02) gas. The gas is toxic, and the battery MUST NOT be abused in anyway
which may cause the battery to rupture.
If the battery compartment becomes hot to the touch,
if you hear a hissing sound (i.e., battery venting) or smell irritating gas (sulfur dioxide),
IMMEDIATELY TURN OFF the equipment and Ieave the area.
1. Allow equipment to cool at least one hour.
2. Remove and replace battery after equipment has cooled to the touch.
3. lf there is a safety incident or if you believe a safety hazard exists, notify your local Safety
Office/Officer; file a Quality Deficiency Report, SF Form 368; and notify CECOM Safety
Office, Ft. Monmouth, NJ at AV 995-3112.
4. There is a discharge device built into all new batteries. instructions on its use will be supplied
with the battery.
DO NOT heat, short circuit, crush, puncture, mutilate, or disassemble a Li-S02 battery.
DO NOT use any Li-S02 battery which shows signs of damage, such as bulging, swelling,
disfigurement, a brown liquid in the plastic wrap, swollen plastic wrap, etc.
DO NOT test Li-S02 batteries for capacity.
DO NOT recharge Li-SO2 batteries.
DO NOT dispose of Li-S02 batteries with ordinary trash/refuse. Turn in Li-S02 batteries to
your local servicing Defense Reutilization and Marketing Office.
DO NOT store batteries in unused equipment for more than 30 days.
DO NOT store Li-S02 batteries with other hazardous materials. Keep them away from open
flame or heat.
DO NOT use a HaIon type fire extinguisher on a Li-S02 battery fire.
In the event of fire near Li-S02 battery (ies), rapid cooling of Li-S02 battery (ies) is important.
Use carbon dioxide (C02) extinguisher. Control of equipment fire, and cooling, may prevent
battery from venting and potentially exposing lithium metal. In the event that lithium metal
becomes involved in fire, use of a graphite based Class D fire extinguisher, such as Lith-X or
Met-L-X, is recommended.
