All I can add after losing some gear to bad 'good batteries' is to keep a date checklist on all equipment with batteries.
6 months or 12 months has passed, used or not, and they look and perform like new? 2 years?!! get them out of there NOW!!!
Or, jerry rig an external plastic battery supply with internal connections that can be reversed anytime
or just take the batteries out of equipment that you don't use that often, it's less of a hassle than blowing cash on a battery trashed item,
or the mega hassle of a bad news battery cleanup and repair
I don't trust rechargeable batteries either, just one of them with continence issues will do the vile deed on your gear just as well as alkalines
oh yeah, and beware of audiophool grade batteries like lithiums and the like, and the marketing BS and price tag that goes with them.
I just tossed out 4 sealed unused twin packs supplied with a DSLR camera, a top brand name battery brand btw that were sitting in a dry box for almost 4 - 5 years.
What a sight, so much for saving them for a rainy day or use as demos if selling the camera.
FWIW: Multimeters that take a 9 volt battery in a separate compartment at the bottom and or away from the main board to me are keepers, regardless of their specs, be it Fluke, Jaycar, whatever...
Worst case battery jizz is a straightforward mop up and a generic 9 volt plug lead = $1 ? soldered in,
if the corroded connectors are welded to the battery or just too crusty beyond saving.
A skeptical observer might suspect some equipment and battery companies with mutual shareholdings, may have a good thing going to turn over easy guaranteed dollars...
Nah, can't happen
