Query: This is not a CMOS battery.

I paid about $15 for a $2 watch battery I could have bought at Staples or Radio Shack. This is not a CMOS battery. A CMOS battery has leads soldered to it that plug into the computer. Most customers do not have the means to do this soldering on their own, and moreover it is rather dangerous to heat batteries. I will never again buy anything over the Internet for which an image is not available.
