Regarding battery load test:
Because of the high load on the battery during this test (a high current flows) the battery voltage lowers.
If the battery is OK, the voltage only goes down to the minimum voltage specification.
If the battery is malfunctioning or only faintly charged, the battery voltage will drop rapidly to below the displayed minimum voltage.
After the test, this low voltage remains steady over a longer time before the voltage slowly increases.
