Yes properly maintained camers is the key... Not many people have their equipment serviced anymore. They like to wait till it drops dead, then justify it was a piece of junk n buy another ab-used camera.

Btw batteries have come a long way with lithion. They are real preformers. But other limitations contribute in cold conditions. ... Motors in auto focus, film transport motors, relays... Too many parts that can't run dry.

I wonder what film was used on the moon? I read an article from a polar expedition that had serious problems with brittle film breaking while advancing frames. The camera itself had no problems at all.
