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.”
as a kid I would shove them up my nose not to be seen again until out they would pop from the other side…miraculously charged.
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
