Could be earwax buildup in the buds.  Builds up slowly over months at
roughly the same - but not _identical_ - rate in each side. That seems
to match your symptoms with the original batteries: first one dies,
then after some indeterminate elapsed time the other dies with no
sound but batteries measure good.

 I'm A bit unclear on how wax buildup on some external surface could in
any way influence the internal electronics?

Nothing to do with the electronics. The wax blocks the small
hole in the earbud where the sound comes out.
