10、mple batteries that are to be assigned to a capacity test (except for the LR1) shall be equally divided between the designated capacity test and the ca pacity test ending in P (e.g. I and IP). The odd battery, if present, is assigned to parallel discharge capacity test. For the capacity tests that d
11、o not have the Ps, the batterys legs shall be discharged in series. For the capacity tests that have the Ps, the batterys legs shall be discharged in parallel. Initial voltage delay: During the I, H, HT, and IT discharge tests of the two (2) 12 volt sections connected in series under the designated
12、loads, initial voltage below the 20.00 volt minimum volt age cannot exceed a 5.0 second duration. During L and LT discharge tests initial voltage below 20.00 volts cannot exceed a 60 second duration. During the IP, HP, HTP, and ITP discharge tests of the two (2) 12 volt sections connected in paralle
13、l under the designated loads, initial voltage below the 10.00 volt minimum voltage cannot exceed a 5.0 second duration. During LP and LTP discharge tests initial voltage below 10.00 volts cannot exceed a 60 second duration. Connector: The connector configuration a nd operating temperature range requ

The connector shall be in accordance with SC - C -179492 with the following exceptions: (1) Sheet two of SC - C - 179492 does not apply. (2) Mounting screws are op tional. (3) Operating temperature range for the connector shall be from a
15、low of - 55 o C to a high of 125 o C. (4) The connector test described in paragraph 4.7.15 shall be performed 10 times with SM - D - 687888.

17、 . METHOD OF EXAMINATION AND TESTS : Capacity tests: (1) Storage: Details on storage conditions for all specified capacity tests are described in the basic specification. (2) Discharge: Cells (forced discharge): Two cells shall be discharged at 2.0 amperes at 70 + 5 o F to 2.0 volts. Eac h discharge
18、d cell shall then be connected in series to nine fresh cells. Each string shall be discharged at 2.0 amperes at 70 + 5 o F for 3.4 hours. Batteries: For all capacity tests that do not end in P, except the LR1, H and HT, the batteries shall be dis charged in the 24 volt mode by connecting pins 2 & 4
19、and discharged between pins 1 & 5 at 2.0 amperes constant current to cut - off volts (zero volts for the I test). For the H and HT capacity tests the batteries shall be discharged in the 24 volt mode as d escribed above, at 2.0 amperes for five minutes, followed by open - circuit for five minutes. T
20、his cycle shall be repeated until the closed - circuit voltage reaches cut - off volts. For the LR1 test, batteries shall be discharged in the 24 volt mode as descri bed above at 145 milliamperes to 20.5 volts, then at 5.5 watts to 3 volts. Forced discharge: After discharge to zero volts on the I ca
21、pacity test, the batteries shall be force discharged in the 24 volt mode as described above at 2.0 amperes for a Copyright Communications - Electronics Command Provided by IHS under license with CRAINot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL - PRF - 49471/
22、3A(CR) 5 minimum of 10 minutes. After discharge to zero volts on the IP capacity test, batteries shall be force discharged with the two 12 volt sections connected in parallel at 4.0 amperes constant current for a minimum of 10 minutes. Overload test: Batteries shall be discharged in the 24 volt mode
23、 as described above at 4 amperes. Abuse test predischarge: Designated samples shall be discharged in the 24 volt mode as described above at 2.0 amperes for 1.7 hours. Abuse test, pulse discharge: Batteries shall be discha rged in the 24 volt mode at 2.5 amperes for 1 minute followed by 1.8 amperes f
24、or 4 minutes, cycled continuously to cut - off voltage. For all capacity tests that end in P, except the HP and HTP, the batteries shall be discharged with the two 12 volt section s connected in parallel at 4.0 amperes constant current to cut - off volts (zero volts for the IP test). For the HP and
25、HTP capacity tests the batteries shall be discharged with the two 12 volt sections in parallel at 4.0 amperes constant current for five m inutes followed by open circuit for five minutes. This cycle shall be repeated until the closed - circuit voltage reaches cut - off volts. Closed - circuit voltag
26、e (Battery and cell string tests): Load resistance of 5.0 ohms shall be used between socket holes 1 & 4 and 2 & 5. Voltage shall be 10.0 volts or greater within ten seconds. Cell closed circuit test: Load resistance of 1 ohm shall be used. Voltage shall be above 2.0 volts in 5 seconds. Marginal nota
