MIL-B-49030A
3.13.2 Terminal markings. On batteries having socket-type terminals, all markings such as polarity, voltage, and
the unit of battery (A, B, or C) shall appear on the face of the battery bearing the socket. On other type terminals, the
terminal markings may appear on the top or the side of the battery, or both. Markings shall indicate clearly the
terminals to which they refer.
3.14 Recycled, recovered, or environmentally preferable materials. Recycled, recovered, or environmentally
preferable materials should be used to the maximum extent possible, provided that the material meets or exceeds the
operational and maintenance requirements, and promotes economically advantageous life cycle costs.
3.15 Pure tin. The use of pure tin, as an underplate or final finish, is prohibited both internally and externally. Tin
content of (product) and solder shall not exceed 97 percent, by mass. Tin shall be alloyed with a minimum of 3
percent lead, by mass (see 6.3).
3.16 Workmanship. Batteries shall be processed in such a manner as to be uniform in quality and shall be free
from defects that will affect their life, serviceability, or appearance.
4. VERIFICATION
4.1 Instrument accuracy.
4.1.1 Voltmeters and ammeters. All voltmeters and ammeters used in testing the batteries shall be accurate within
1 percent of the full-scale value. The voltmeter and ammeter ranges shall be such that all readings are taken on the
upper half of the scale. The sensitivity of voltmeters shall be not less than 1,000 ohms per volt.
4.1.2 Resistor tolerances. During all tests involving discharge through a resistance, such resistance shall be
accurate within the following percentages:
Percent
Up to and including the 25,000 ohms
0.5
From above 25,000 ohms to and including
1 megohm
1.0
Above 1 megohm
5.0
In determining the resistance used as a test load, the resistance of all continuously operating voltmeters shall be
considered as part of the specified load.
4.1.3 Timing. Timing equipment shall be accurate within 0.5 percent.
4.2 Classification of inspection. The examination and testing of batteries shall be classified as follows:
Materials and components inspection (see 4.4).
a.
b.
First article inspection (see 4.5).
c.
Conformance inspection (see 4.6).
