Most batteries come with a raised area on their negative terminal to allow the heatshrink sleeve to curl round at the end, but some batteries have a flat base and the heatshrink can stop them making a proper connection in some chargers and battery holders.
By using a sharp knife to slice the ring of heatshrink on the negative terminal off, you can make those batteries work in most instances.

usually grinding the dirt down with a fiberglass eraser does it. and there is no label covering the bottom of the AAA NiMh batteries. Figured that out long ago.
I'd probably have dabbed a little solder onto the too-flat terminal. I think your solution is probably cleaner.
That's so much simpler than my applying a dab of solder to the -ve contact on the charger.
Edit: I have a bad habit of REALLY over-engineering things.
I got some catching up to do from a few videos you've posted in the last few days.
Keep them coming sir
