Due to the various differences between a real battery and the average
bench supply (*), we should perhaps define those tests with a battery
and low-resistance contacts.
So for short tests, the test condition would be an initial battery
voltage of N volts, and the final voltage would have to be within a
narrow range of that.
(*) Note: some of the supplies you saw in the lab in Taipei are actually
extremely fast and should simulate a battery quite accurately. They
also cost about as much as a good oscilloscope ...
Bench supply tests would still be useful for tracking down leaks and
