These fit my Xfinity home alarm sensors perfectly and were about half the price of name brand ones.
These fit my Xfinity home alarm sensors perfectly and were about half the price of name brand ones. I don't know how long they'll last, but for the price, I'm very happy.

Great price for CR2 batteries
Not much to say about these batteries – I don’t have a lot of things that use them, but some local stores in my area want to sell me one battery for the price I paid for this 10-pack. Not sure if that one battery is 10x better than these; I guess I’ll find out. There’s no date code on the box or on the batteries, so I have no clue when they were manufactured, but the one I’ve used so far measured 3.3V out of the box, so I’m satisfied.
