8、except for the L and LT capacity test conditions: BA - 5368/U batteries shall be tested at 14 + 5F in lieu of the - 20 + 5F of 4.7.9.1.3 and 4.7.9.1.5. (2) Discharge Cells (Forced Discharge ): Two cells shall be discharged at 50 milliamperes at 70 + 5F to 2.25 volts. Each discharged cell shall then
9、be connected in series with three fresh cells. Each string shall then be discharged at 50 milliamperes at 70 + 5F for 20 hours. Batteries: For all capacity tests except the LR1, the batteries shall be discharged at 50 milliamperes constant current to cut - off volts (zero volts for the I test). For
10、the LR1 test, batteries shall be discharged at 20 milliamperes to 10 volts, then at 0.9 watts to 8 v olts. Forced Discharge: After the batteries have been discharged to zero volts on the I test, batteries shall be force discharged at 50 milliamperes for a minimum of 5 minutes. Overload: Batteries sh
11、all be discharged at 100 milliamperes. Abuse test pr edischarge: Designated samples shall be discharged at 50 milliamperes for 10 hours. Abuse test, pulse discharge: Batteries shall be discharged at 90 milliamperes for 1 minute followed by 40 milliamperes for 4 minutes, cycled continuously to cut -
12、off volt age. Closed circuit voltage (battery and cell strings): Load resistance of 130 ohms shall be used. Voltage shall be above 10.6 volts within 5 seconds. Cell closed circuit voltage: Load resistance of 32.5 ohms shall be used. Voltage shall be above 2.6 5 volts in 5 seconds or less. Marginal n
