The Saturn's first battery lasted 15 years, and apparently the second one lasted 9.
Three sounds too short but maybe I am
My experience is 3 to 5 years with most coming in around 3 to 4. Environmental loads may have a different impact for all I know. I know our HVAC systems in the cars are one all the time and we don't have much weather to enjoy driving with the windows open.
