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 &#…
Well the pros and cons of the multimeter are addresses in the video! He uses a meter on a dead battery and it still shows a deceptively reasonable voltage when not under load. The built-in tester draws more current.
My technique is to use the 10a mode on the multimeter and check the battery. A full AA will do nearly 10 amps and dead ones much less. Careful with larger cells or rechargeables since you might blow the fuse in your meter.
I was a kid then, but I remember that I had to push so hard my fingers hurt… I used a multimeter.

That sounds a little like testing matches “Yes, that one works. I mean: worked.”

Let me introduce You to these spent uranium fuel rods.

you just had to put one of the other fingers on the battery groumd and not push that hard iirc
