Batteries last a maximum of 5 years. I had to nurse mine a lot to get 4 1/2 years out of them, and when I finally did replace them, I wondered why I didn't do it sooner. Way better starting, and no strange codes being thrown. Anyway, if your batteries are original, then I am completely shocked at how long they have lasted!
Sorry that you are dealing with the New England cold right now, it looks/sounds brutal!
