Sunday 2-15-2015 the battery failed due to old age / cold weather.

I have been expecting this, and bought a new battery in January.

The new battery has been on the passenger cabin floor, waiting for time or need to install.

Frosted fingers from cold tools and the new battery had me off to work, arriving on time.

Leaving work, our ambient was -10° F.
Normal glow, quick start, but notably slow to warm up = blame it on the weather.

I am very happy.
