Review on 10 Pack Of SURPOWER CR1632 3V Lithium Batteries With 5-Year Warranty by Fock Dean

I use 2 at a time in my Extreme Dog Fence collar, no need to tape them together; just stack one on the other and screw in the cap. A pair lasts two weeks. 9 out of 10 batteries were at 3.2V even three months after receiving; am I upset about the 10th battery that tested 2.9V today? Not one bit, I'm ordering them again, three months for $11 that's about one dollar per week, can't complain about this excellent value over the Extreme Dog Fence batteries or even Duracell batteries which is most costly for a 3-pack.
