Bests & Worsts Reviews from Amazon

So, I purchased a pack of these a month ago (11-Dec-2015) and was using them as expected, when I hit a snag. At LEAST 3 batteries from this pack were marginal/undervoltage (<1.5V) out of the box. I found this out because I had replaced a pair of batteries in one of my remote sensors for my wall mounted indoor weather station because the had sensor stopped working. I thought maybe I had inserted them wrong, but no, the +/- marks matched the batteries. So I tried several times to reset both the sensor and the station with no luck. At one point, I had all of the batteries out to force a reset and put them back. But now my weather station would not power up either. That was the clue I needed. I got my trusty multimeter (with battery tester) and checked out all 5 of the Amazon Basics AA cells. Like all NEW 1.5V batteries, most of them showed >1.6V which is typical. Two of them were at 1.48V, which was just low enough for them to be considered "undervoltage". No new AA battery should arrive with <1.5V. This is the first and only time I have ever seen fresh batteries arrive in a "not as new" condition with caused problems with my electronics. I generally like all of the various Amazon Basics products (mice, HDMI cables, etc.), but this has caused me to have doubts about not only their AA batteries, but all of the house branded products. Buyer beware (Caveat Emptor) seems to be the bottom line.
