Poor Fit
Battery wire was much too long. Many times longer than the wire on the battery it was replacing. The wire length made reassembling the Nest extremely difficult.

Problem was not with the battery it was the device.
The battery did was not the fix for my problem.

Not for amateurs
Have no idea if this is quality as I couldn't figure how to put the nest thermostat back together properly. Not for amateurs.
