An even better test would be to test the same battery before discharge and after.

- teekert 3y agoYeah that’s basic science.
- bmacho 3y agoNo that would be far far worse test than having 2 equivalent batteries, and discharging one of them. First, it is easier to measure differences than absolute values (by eye, but even with precise equipment), second it automatically cancels out the affects of temperature, humidity, pressure etc. (Okay, you know that these things doesn't matter in this experiment, still.)
- gwd 3y agoOr perhaps, buy six identical batteries, labeled 1-6; randomly charge them to two different levels (100% and 60%), three each, noting down which was which; then hand them to another set of people, who have only seen the numbers, and bounce each of them, to see how reliably they can tell the difference.
- londons_explore 3y agoOnly works with alkaline non-rechargeable batteries, but apart from that, yeah.
- dotancohen 3y agoWhich is arguably the most common type of AA sold.
- zoky 3y agoOr even better, buy six million identical batteries, label them, discharge them randomly, run some rudimentary tests, and announce you’ve identified a room-temperature superconductor! …Too soon?
