Battery Test
Battery test is used to detect the battery capacity. Battery capacity is an important index of battery, it
reflect the using time and reliability issue of battery.
During the battery test, the voltage will decreasing with the increasing of discharge time, so it need to
set the cut-off voltage, the test will stop when it meets the cut-off voltage.
Parameter of Battery Test
In battery test, select discharge mode and set the load parameter and cut-off voltage for the mode.
The electronic load will automatically stop when the battery discharges to the cut-off voltage.
