iMac hibernation mode

My friend got a new MacBook Air, and sent me his old iMac13,1 (21.5”, 8GB RAM, 1TB HDD, USB kbd/ms). I zeroed out the HDD and installed Sierra anew on it.
It has the problem of when it goes to sleep for more than 6 hours (or so), it goes into ‘hibernation' mode. It takes a click on the power button to get it to come back. But even then, it presents a hibernation wake screen, apparently restoring itself from the sleep image, like when you restart a MacBook that ran out of battery power: https://km.support.apple.com/library/content/dam/edam/applecare/images/en_US/osx/progress_bar_wake.png
I've set the following:
% sudo pmset standby 0
% sudo pmset autopoweroff 0
The above prevents it from going into hibernation mode. When it tries to, it simply wakes itself up again. So I’ve got it now in this cycle, light-sleeping then a full wake up, over & over on its own, every so many hours. Not normal.
The Energy Saver prefs are all set to their defaults. Could this be a dead mobo cell battery?
