State of Charge Indicator: Not applicable Capacity tests: When the battery is tested in accordance with the methods of examination and tests of this specification, the minim

6、um capacity test requirements shall be as specified below. Capacity Tests Minimum Capacity in Hours to 2.00 Volts I 18 L 10 H 18 HT 16 LT 10 IT 17 Initial voltage delay: When the battery is subjected to the I, H, HT, and IT capacity tests, initial closed - circuit voltages below 2.00 volts cannot ex

7、ceed a 5.0 second duration. For the L and LT Copyright Communications - Electronics Command Provided by IHS under license with CRAINot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-PRF-49471/4A(CR) 3 capacity tests initial closed - circuit voltages be low 2.00 vo

8、lts cannot exceed a 10.0 second duration. Negative Terminal Insulation: The negative terminal shall be electrically insulated from a flat surface placed against the side of the battery (the 0.749 inch dimension) even when the battery is not pa rallel to the surface. METHOD OF EXAMINATION AND TESTS :

9、 Capacity tests: (1) Storage: Details on storage conditions for all specified capacity tests are described in basic specification. (2) Discharge: Discharge current for all capacity tests shall be 50 milliamperes constant current. All samples shall be discharged to cut - off voltage except for the I

10、test; I test samples shall be discharged to zero volts, then force discharged at 50 milliamperes for a minimum of 5 minutes. Abuse test predischarge : Designated samples shall be discharged at 50 milliamperes for 9 hours. Abuse test, pulse discharge: Batteries shall be discharged at 55 milliamperes

11、for 1 minute followed by 40 milliamperes for four minutes, cycled continuously to cut - off voltage. (3) Cell Forced Discharge: Two cells shall be discharged at 50 milliamperes at 70 + 5 F to 2.0 volts. Each discharged cell shall then be connected in series with one fresh cell. Each string shall be

12、discharged at 50 milliamperes at 70 + 5 F for 18 hours. Clos ed - circuit voltage (Batteries and cells): Load resistance of 20 ohms shall be used. Voltage shall be above 2.0 volts within five seconds. Negative Terminal Insulation: When a ten pound force is applied across the battery diameter, no ele

13、ctrical contact shall be made even if the maximum angle between the battery surface and the contact surface is 15. The contact surface to be used in the test shall be a flat iron or steel plate measuring 3/4“ x 3/4“. Its thickness shall be 1/8“. These dimensions are all minimums. The lack of electri

14、cal contact shall be demonstrated with a voltmeter set so that 3.00 volts is readily evident. During the test, one terminal of the voltmeter shall be attached to the positive terminal of the battery and the other terminal of the voltmeter attached to the reverse side of the contact surface. Zero vol

15、ts shall be read.
