Not having any children about the house for circa 30 years, I guess my personal priorities may differ somewhat and I was greatly frustrated to think perhaps I was suffering some degree of incapability relative to basic electrical understanding..... Though seems I managed to work my way through it.
I expect that the coating must be conductive to some extent but it seems not enough for some devices that may not generate enough spring pressure or may not have teeth to cut into the coating as the battery is slid into place, such as in my garage door remotes....
I wonder how many batteries and or devices might be binned, if this issue is as common as I imagine it might be..?
It seems we may live in a world of ever increasing unintended consequences.. ?
Additionally, I wonder if the foul tasting coating might alter it`s electrical resistance with the passage of time while the battery is within it`s packaging... ?
