EEVblog #789 - Batteriser Monkey BUSTED!

Dave shows why power supplies are no different to batteries when determining cutoff voltage, busting the claim of Batteriser using their own monkey experiment.
It shows the incorrect method used by Batteriser to come to their false conclusion.
Discharge testing of alkaline batteries is performed, and correct probing of the monkey toy shows that the cutoff voltage with both batteries and the PSU are identical, and does take into account the electrochemical ionic internal resistance of the battery.
Dave explains why using a PSU is the standard industry technique for measuring product battery cutoff voltage.
Also discussion on ionic resistance recovery graphs and energy density in a battery.
