Sealed batteries do not require a vent , therefore no air passage - less influence of ambient exterior temps to the bank. Perhaps on a small bank this would have an influence.
On a large bank in a low usage scenario, IE: second home with no one home, the system may be full by 10AM and the fan runs for most of the day inducing cool air. Granted most systems have a present [physically] home owner. I have many systems that float for a good part of the winter, awaiting the arrival of either the owner for a week or spring.

HI Dana, I'm curious about why you differentiate sealed vs. flooded batteries?
