11、e time required at the beginning of discharge of the battery to reach a voltage of 10.00 volts after the specified load is applied shall not be more than 5.0 seconds. For the L and LT capacity tests the time to reach a voltage of 10.00 volts after the load is applied shall not be more than 60 second
12、s. METHODS OF EXAMINATION AND TESTS : Capacity tests: (1) Storage: Details on storage conditions for capacity tests are specified in basic specification. (2) Discharge: Cells (forced discharge): Two cells shall be dis charged at 2.0 amperes at 70 + 5 o F to 2.0 volts. Each discharged cell shall then
13、 be connected in series to four fresh cells. Each string shall be force discharged at 2.0 amperes at 70 + 5 o F for 3.8 hours. Batteries: The A 2 unit ( - A 1 , - A 2 , to + A 2 ) shall be discharged as follows: For all capacity tests, except the LR1, H and HT, the batteries shall be discharged at 2
14、.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 at 2.0 amperes constant current Copyright Communications - Electronics Command Provided by IHS under license with CRAINot for ResaleNo reproduction or network

This cycle shall be repeated until the closed - circuit voltage reaches cut - off volts. For the LR1 test, batteries shall be discharged at 160 milliamperes to 10.5 vo lt
16、s, then at 2.75 watts to 1.5 volts. Forced Discharge: After discharge to zero volts on the I capacity test, the batteries shall be force discharged at 2.0 amperes for a minimum of10 minutes. Overload test: Batteries shall be discharged at 4 amperes. A buse test predischarge: Designated samples shall
17、 be discharged at 2.0 amperes for 1.9 hours. Abuse test, pulse discharge: Batteries shall be discharged at 2.5 amperes for 1 minute followed by 1.8 amperes for 4 minutes, cycled continuously to cut - off volta ge. Closed - circuit voltage: Closed - circuit voltage measurements shall be made with a d
18、irect current voltmeter of proper range and sensitivity (see basic specification), using load resistance as shown in the following table: UNIT RESISTANCE MINIMUM PERM ISSIBLE VOLTAGE A 1 6.5 ohms, + 1% 1.9 volts A 2 5.0 ohms, + 1% 10.0 volts (this applies to cell strings as well) Voltage shall be ab
