The battery works fine like any other battery.
As an engineering student, I noticed a bitter coating on the battery and tested it.
I purchased a pack of CR 2032 Duracell batteries and 3 of them did not work in my car keys. I thought I was doing something wrong, but after replacing them with some unknown LiCB brand, I tested them using a multimeter and found that none of them had 3V, it was 2V or less. I am disappointed with the purchase.
