TM 11-6140-203-14-3
NOTE
New batteries are prepared for service by direct support, general support, or depot maintenance
personnel only.
c.
3-3. Battery Service Record-Format
a.
Record Format. When placing a battery in service for the first time, prepare and use the format, in
duplicate, similar to that shown in DD Form 314 (Preventive Main- tenance Schedule and Record (Card)) of TM
38-750 to provide a record of each individual battery. This record will serve as a verification of maintenance
accomplished.
b.
Recording Procedure.
(1) Affix one copy of the record to the battery immediately after formation of the battery at direct
support.
(2) File the duplicate copy of the record at the direct support shop that accomplished the formation
of the battery.
(3) Entries are to be made on the copy mounted on the battery by organizational Shop personnel
as necessary.
(4) Make entries on the direct support file copy every time the battery is in direct support shop for
service.
(5) Make cross entries (direct support personnel), as necessary, to update on each file copy of the
battery record. When records are filled, start a new copy. Direct support personnel should remove old record
from battery and affix current record to battery. Direct support personnel should retain all duplicate copies in
their file.
3-4. Installation of Nonaircraft Nickel-Cadmium Battery
NOTE
Place into service only new batteries that have been prepared for service by higher category of
maintenance personnel.
Installation of the particular nonaircraft nickel-cadmium battery will differ from ground system to ground system.
For installation procedures of each different nonaircraft nickel-cadmium battery, refer to the manual covering
the ground system. In addition, observe the following:
a.
Securing Battery in Position. When installing the battery in its position to power a ground system,
see that all electrical connections are made secure. Leads to the battery should be of sufficient size to carry the
maximum current. The battery should be secured by holddowns.
b.
Venting of Gases.
During the charging cycle, some hydrogen and oxygen gases are evolved. When
the battery is installed in a confined location, provide some means of ventilation from this confined area to
avoid accidental ignition of the hydrogen. Always charge with cover removed.
3-5. Emergency Procedures
Alkaline or nickel-cadmium batteries may experience an overheated condition resulting from internal shorting
or thermal runaway. The overheated battery presents a hazardous condition to equipment, vehicle, and
personnel. When an overheated battery is detected, turn off charging source, disconnect battery and wait for
battery to cool. Emergency personnel should open the battery compartment, check for the following conditions
and then take the action indicated.
a.
If flame is present, use the available extinguishing
agent.
b.
If no flame is present, but smoke, fumes or electrolyte is being emitted from the battery or vent
tubes, use water fog to lower the battery temperature.
c.
If no flame or fire is present, and smoke, hydrogen/oxygen gas or electrolyte is not being emitted
from the battery or vent tubes, ventilate the battery compartment.
WARNING
C02 is an acceptable fire extinguishing agent once a fire has developed. In no case should C02 be
directed into a battery compartment to effect cooling or displace explosive gases. The static electricity
generated by the discharge of the extinguisher could explode the hydrogen/oxygen gases trapped in the
battery compartment.
d. Following the visual check and the action indicated above; emergency personnel should disconnect
and remove the battery. Additional cooling may be accomplished with water fog.
