As has been said, local climate determines battery life. NJ probably isn't above 90º 70% of the year. Hate to keep preaching, but I sold batteries for a year here in the Houston area. Ninety percent of the cores had date codes within the preceding 4 years. I guarantee you'd've replaced your Sienna battery at least once if you lived down here. Keeping a car garaged also helps with battery longevity.
On the flip side, it doesn't snow down here, therefore there's never salt on the roads. Our vehicles generally don't acquire any rust or body rot.
