Bests & Worsts Reviews from Amazon

I don't know if these are expired or knock off batteries, or if Energizer standards have just dropped. But I got the pack to use in my garage door opener. I changed out the battery that had died, and put in the a new one. The door would open maybe 1 out of every 5 pushes..just like with the old dying battery. This happened with half the batteries, and I haven't tried the other half. I stuck a multi-meter on these batteries..and yep the voltage just isn't up to snuff. These say 3V, but the multi meter reads 2.8...which is just enough to work..but not enough to be reliable. Put the multi meter to a fresh 2032..and it reads about 3.2...which is what is really should be.
