Im going to call BS on this. No scientific method here, just a claim. Looking at the youtube comments and how many are are giving props for a great way to test them... Well, its easy to understand why so many in this day and age are the force voting and happy with the crap our government is throwing at us.

OK, I'll need to test this out for myself before relying on it, but assuming it's true, that is awesome. Very useful. Thanks.

Very cool - I hope I can remember the difference! Good if it sticks the landing, bad if it doesn't. Got it.

This ranks right up there with unlocking a car door with a cell phone or harvesting AA batteries from a 6V lantern battery. For starters, you have two different brands with subtly different case styles. Also, the internal composition (both mechanical and chemical)will be different. In short, if this were true, identical batteries would have been used.

As an electronics tech and former 31b20 radio mechanic, and possessing a surplus of digital volt meters, I thought that I would test the test. One dead pink energizer AA cell, reading 1.193 volts, and dropped from 10 inches, bounced about 2 inches, another energizer AA cell reading 1.480 volts bounced less than 1 inch. The dead cell weighed 362 grains and the good cell weighed 364 grains. They were 2 years different in expiration dates, so there may be manufacturing variations which could account for the weight differences. 2

Tried it. Using a bunch of double-As, dropping them from 2-3 inches high onto their flat (negative) ends, some stood up. Some wobbled and fell. But all tested good with at least 1.5 volts with my voltmeter. Hence, my conclusion is BULLSHIT.
