In 30 years I've replaced countless dead or weak #2032 lithium coin cells on motherboards, most between 5 and 8 years of age. My point is it's not rocket science to get one out of a blister-pak, even for a 74 year old with no feeling in his fingertips but plenty of arthritic pain in his joints....until this morning.
I was getting one out of a twin-pack this morning for repaired Dell laptop and I pulled and I cut and I cut and I got my fingernails in there and it was like pulling teeth for a good 5 minutes, not 10 seconds as usual.
I was being careful with my knife because I'm on a blood thinner (Warfarin Sodium / Coumadin).
After a lot a grunting and mumbling under my breath (wife in the next room) I caught sight of the reason...instead of the single layer of clear plastic glued to the card, there was an inside layer on the UNDERSIDE of the cell and it was bonded to the top/outside! And because it's crystal clear (and I wasn't expecting it) I just could not get the #$%& coin cell separated from the outer skin until I saw why.
I opened an identical 2 pack that I had purchased earlier in the year and it was not like this one...so, be advised this is a new deal, likely to discourage theft of 1 cell off the display...or a plot to get old farts to accidentally cut themselves and bleed to death.
I peeled it back so it's visible to you in he image below...that's on the underside, opposite where we see the "2032" marking.
