For the first time in history tonight I pro actively replaced by battery BEFORE that first really cold morning of the year when 4-5 year old batteries die all over town. Drove over to the parts store and had it tested because I had noticed it was sounding a little squemish lately. It tested at 53% of capacity or whatever so I had them put in the "gold" model with the most cranking amps that fit.
Mission Accomplished! I also picked up another jug of Rain X orange
