Remember Duracell’s PowerCheck? The idea was that a strip built into the battery would show if the battery was good or not. Sure, you could always get a meter or a dedicated battery tester &#…
Although, he admits in the video to "faking" his footage of it working, by using a off-camera heat source. (His batteries were quite dead.)
But, as someone that lived through this time, they did work, as long as you pressed hard enough in the right places. It was hard to tell if the battery was dead or if you weren't pressing hard enough
If you watch the whole video he does it more "for real" later on, plugging the casing into a power source to simulate a battery discharging.. Plus I've had some of these PowerCheck batteries, and they were not old, it was like... 2017? So maybe they rebooted it for a short time at some point?? Anywho, if you pressed really hard it did work I think, but also I think I was doing it wrong for a long time as well lol
Hopefully not because the kind of batteries that work with this reader are awful batteries. Single use disposable batteries are an absolutely stupid idea we should be moving away from
I have no lack of proper test equipment, this is actually kind of nice because the kids can use it easily without trying to wrangle a battery and two leads.
