14、ied 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 Each discharged cell shall then be connected in series to two fresh cells. Each string shall be force discharged at 2.0 amperes at 70 + 5 o F for 3.2 hours
15、. Batteries: For all capacity te sts, except the LR1, H and HT, the batteries shall be discharged 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 through 2.0 amperes constant current for five minutes fo
16、llowed by open circuit for five minutes. This cycle shall be repeated until the closed - circuit voltage reaches cut -off volts. For the LR1 test, batteries shall be discharged at 135 milliamperes to 6.5 volts, then at 1.7 watts to 1.0 volt. For ced discharge: After discharge to zero volts on the I
17、capacity test, the batteries shall be force discharged at 2.0 amperes for a minimum of 5 minutes. Overload test: Batteries shall be discharged at 4.0 amperes. Abuse test predischarge: Designated sampl es shall be discharged at 2.0 amperes for 1.6 hours. Abuse test, pulse discharge: Batteries shall b
18、e discharged at 2.5 amperes for 1 minute followed by 1.8 amperes for 4 minutes, cycled continuously to cut - off voltage. Closed - circuit voltage test (Batter y & cell string tests): Load resistance of 3 ohms shall be used. Voltage shall be above 6.00 volts within 10.0 seconds. Cell closed - circui
19、t voltage test: Load resistance of 1 ohm shall be used. Voltage shall be above 2.0 volts in 5 seconds.
