There are 2 requirements for a good battery: voltage & current. Terminal
voltage often tells enough, but not always. The other test is to touch

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.
