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 &#…
It failed often enough that it wasn’t all that useful. A cheap battery tester is better. And for 9volts you can also use the tongue test, lol (don’t really though). My grandfather used to do that all the time.
The tongue test works great. Be warned, though, that a full battery will make your tongue go numb. It’ll feel like you have a big hole in the middle. Try it.
Ouch, I never had that problem, but I only barely touch it, lol. It’s a little shock and slightly numb briefly. But fortunately I never had full numbness that lasted more than a second or two. But I haven’t done it in a long time since I have a tester now. 😁

Everytime i test a battery like this, my wife just shakes her head and reminds me that I’m definitely from Kentucky lol
