I am not compulsive. I can quit making lists any time I want...
However, I got tired of trying to remember what kind of batteries the various stuff uses, when they were last inspected, etc. so I made up an Excel spreadsheet to track them all.
Stuff that gets used rarely gets batteries installed before use and is stored without batteries. (To prevent corrosion damage)
The rest get inspected and I run a DMM on the batteries and replace them if the voltage is low or if the "good until date" is approaching. And the date of inspection / new battery installation is put in the spreadsheet.
I agree. We have way, way too many battery powered toys.
