There are 2 requirements for a good battery: voltage & current.
Terminal voltage often tells enough, but not always. The other test
is to touch probes of a 1A meter to the battery for a fraction of a
second, see how fast the needle flies up. Digital meters generally
can't do this. Keep the probes on & you'll kill both meter & battery.
You'll most likely blow the fuse in the DVM if the battery can exceed
the current range.
Nah, fuses require a fair bit of i squared t. Anyway if someone does
this with a digital they clearly don't know what they're doing.
But it's you that said it will kill the DVM...
I see some consistency here, where the facts are bent to meet opinion.
