In hindsight I never, ever used them on a partially spent battery (because who takes out batteries to check their charge remaining?) so I have no idea how well they worked anywhere between 0% and 100%.
I tested partially spent batteries all the time, because my childhood home was full of imps who would take one or two batteries out of a remote to power their DS or other handhelds, then replace them after gametime was over. So if the remote wasn’t working it was nice to just check a battery for charge than to assume one or all batteries were dead before stealing batteries to game with.
These worked just fine if the battery had charge.

Tap for spoiler
one of the imps was me
The DS had a rechargable battery, though.
You’re right, I never had a DS! I forgot the name of the GameBoy and my old brain did a silly substitution
Pedantry! It’s not a crime but it feels like one. Fitting for a defaultusername…
