INSTALLATION

3-1. Unpacking

Battery, Storage BB-542/U is packed in protective material as shown in figure 3-1. The storage battery pack should be

placed in a close fitting box as illustrated. One foam pad is placed at each end of the battery for protection, and then taped.

The battery is then placed in a barrier bag and heat sealed closed. A multiple quantity of batteries can be packed in a

single container. Batteries must be packed as specified within a close fitting box conforming to a container length and width

of 48 x 24 inches and the weight not to exceed 100 pounds.

3-2. Checking Unpacked Equipment

a. Inspect the equipment for damage incurred during shipment. If the equipment has been damaged, report the

damage on SF 364 (para 1-3b).

b. Check to see that the equipment is complete as listed on the packing slip. Report all discrepancies in

accordance with procedures given in DA PAM 738-750. Shortages of a minor assembly or part that does not affect proper

functioning of the equipment should not prevent use of the equipment.

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 3-4.

3-3. Battery Service Record

(Not applicable).

3-4. Installation of Battery, Storage BB-542/U

NOTE

Place into service only batteries that have been prepared for service by a qualified

battery service facility. The battery is shipped in an activated-discharged state and

must be charged before being used. See paragraph 4-12.

When installing the battery in its position, 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.

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 all three battery connectors and wait for battery to cool.

Emergency personnel should open the battery compartment, check for the following conditions and then take the action

indicated.

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.
