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

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

Are the origional batteries really undersized, or has the case just warped from
heat? You could wrap the batteries with a few layers of paper, heat the case
with an hot air gun, and insert the batteries to warp it back out.
