After trying several batteries in various states of charge, I concluded that this camera operates properly if any decent battery in it is freshly, fully charged. (Some batteries are better than others though.)
But if its battery becomes weak while it is turned on, one may need to put it into Preview mode so that after one minute, its lens will retract and then its battery pulled in order to turn this camera off.
(Does any one wish to discuss which batteries are equivalent to an EN-EL10?)
