A-A-50799A
3.6 Constant current discharge. This battery charger/analyzer shall provide constant current discharge from 0.2 Amperes (A) to 60 A, for capacity testing.
3.7 Cell voltage balance testing and voltmeter. This battery charger/analyzer shall provide cell voltage balance testing and an internal voltmeter.
3.8 Power source. This battery charger/analyzer shall operate from 110, 208 or 220 V ac, single phase,
50/60 Hertz (Hz) commercial power source with a maximum of 25 amperes current draw.
3.9 Battery temperature. While charging, the battery temperature, measured by a thermometer in the electrolyte of the centermost cell, shall not increase more than 15° Fahrenheit (F) (9.4° Celsius (C)) over temperature prior to the charging cycle. This applies to a battery which is at room temperature prior to the starting charge.
3.10 Environmental non-operating.
3.10.1 Ambient temperature. The ambient temperature shall be -40°F (-40°C) to +159.8 °F (+71 °C).
3.10.2 Altitude. The non-operating altitude of this unit shall be between 0 and 50,000 feet (15,240 meters).
3.11 Environmental operating.
3.11.1 Ambient temperature. The ambient temperature shall be 32°F (0°C) to 122°F (50°C).
3.11.2 Altitude. The operating altitude of this unit shall be between 0 and 8,000 feet (2,438.4 meters).
3.12 Finish. All surfaces of the cabinet shall be finished with paint or coatings which are alkaline resistant.
3.13 Marking. Battery chargers/analyzers supplied to this CID shall be provided with a corrosion-resistant metal nameplate in a visible and safe location on the charger cabinet exterior which shall contain, as a minimum the following information:
a. Nomenclature/name
b. Name of manufacturer c. Model
d. Serial number
e. Year of manufacture f. Part number
g. Input (volts)
h. Input (Amperes)
i. Input frequency (hertz)
(NOTE: The part number marked on the unit pack shall be the CID PIN.)
3.14 Instructions. Brief instructions for operating this battery charger/analyzer shall be permanently mounted on or near the control panel. The instructions and/or diagrams shall be protected against elements that will affect their legibility.
3.15 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.
3.16 Workmanship. Battery charger/analyzers shall be processed in such a manner as to be uniform in quality and shall be free from other defects that will affect life, serviceability, or appearance.
