I have had an infrared, non-contact medical thermometer that was very handy. I have a cold -- or something -- and both my doc at the VA and I are wondering if it might actually be COVID-19 (again). So I pulled out the thermometer, and it was dead.
No problem, it runs on AAA batteries, and I keep those around. Well, one of the batteries fell right out, but the other one wouldn't come out until I had partially disassembled the case to make wiggle room, and used needle nose pliers to extract it. Of course, the battery had leaked, and destroyed the contacts at the base.
So, I'll order a new one from Amazon. This time I'll toss the batteries that come with it, use brand-name alkalines, and NOT store it with the batteries in it.
