I was a kid then, but I remember that I had to push so hard my fingers hurt... I used a multimeter.

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.

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