I think many of the above statements about batteries are incorrect. However, one has to figure out what the question or statement really is.
I think it is relatively safe to say that an unloaded battery has a longer shelf life at lower temperatures. The same may apply to a lightly loaded battery, a smoke detector. If the load is not constant relative to temperature, then that is a completely different story.
A lead-acid battery has a higher open circuit voltage at lower temperatures.
I did not find a good Internet reference, but the two following have some useful information.
