It seems the plastic housing has deformed to slightly oval tubes or

lack of freeboard. Any ideas how to enlarge the bores a bit, no
engineering reamer available. Those silly sandpaper cylinders on a
rubber cylinder "mandrel" for "Dremmels" would do the job if there was
a way to extend the shaft. I'll try the core of a "choc block"
connector as a coupler, but any other ideas?

I'm not sure if it's "deformed".

I have a Garmin, sort of slender and long, and I've had some trouble
with rechargeables in there. The battery cover has a thing in the
middle that you twist to lock it closed. That has been a tight fit. I
seem to recall trying the thing with alkaline AAs, and it was easier to
close that cover.

The closers are Dzus Camlock. Perhaps deliberately undersized bores so
as to lock you in to buying Garmin undersize AA batteries.
If you are forcing home the closer , then you will have the same problem
of the lower cells jammed in the bore. As the moulding around the bores
is highly asymetric, perhaps the plastic releives over time and bends,
anyway my "reaming" has done the trick, crude but effective, GPS still
works BTW
