Hopefully not too Off Topic:
Another gnash to complement the latest russian roulette battery nuke crisis, is those ANNOYING small foam battery nudgers stuck on to the multimeter battery covers that deteriorate badly, and turn into flakey, powdery, sticky slimey gunk.
They shrink/compress, which defeats their purpose for being 'stuck' in there,
and being sticky tend to grip/drag AAA or AA batteries slightly out of their proper contact range, at random.
This can result in a free entertainment intermission on a ballbreak troubleshoot job, with the meter readings playing up depending on how you hold it/switch between ranges/placed on bench etc,
and intermittent standup guest appearances by Mr. Low Battery Warning.
I remove and clean all foam battery nudgers (on Flukes especially).
On a couple of meters the crud actually etched into the Fluke tough plastic,
resorted to medieval scraping, finished with fine steel wool for aesthetics.
I remove them on new gear too because it's the same crap waiting to bite, and easier to get off when new with fingernails or nylon tool.
I replace with something appropriate that conforms better physically, has good springiness and recovery to keep batteries where they should be, and lasts for ages without turning into swamp quicksand.
IMO the foam decay vapor over time can't be doing any tight sealed meter any internal favors either.
Get in early, because it's a hassle performing a major clean up of this sticky moldy foam, especially if mixed with badly leaked batteries.
Crossed fingers the expensive meter will still work, and hold spec after cleanup and a few shots and chasers at the local Isopropyl Pub.
