Battery Service Record-Format

TM 11-6140-203-14-3

NOTE

New batteries are prepared for service by direct support, general support, or depot maintenance

personnel only.

Prepare the new battery for service as given in paragraph 5-5.

3-3. Battery Service Record-Format

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.

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:

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.

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.

If flame is present, use the available extinguishing

agent.

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.

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.
