3) Press [ ] key to Start Testing.
Regarding internal resistance, for the same battery, the smaller
the internal resistance, the better the health status (except for
short circuit). The internal resistance value can be used as a
reference for the state judgment standard of a certain range of
battery performance.
NOTE:
When the battery voltage is lower than the normal test voltage,
the test value cannot correctly determine the battery usage
status, and the test result will display "Charge Retest". At this
time, you need to charge the battery before testing.
When the battery voltage is too high or the vehicle is running,
the test cannot be performed normally, it will prompt "The
voltage is too high, please stop the fire! Turn on the headlights
for 3 minutes before measuring".
For batteries that are deeply in deficit (such as when the
vehicle is not in use for a long time and the battery is not
charged in time; the lights and car doors are forgotten to be
closed, causing the battery to fail due to severe battery failure
and cannot start the vehicle, etc.), the actual detection process
may also prompt "Please replace the battery". Such a battery,
please consult the battery manufacturer first, and perform the
test after charging and restoring according to the charging
method provided by the manufacturer.
