My K-01 has started zeroing out the date back to 2012, everytime I turn it off, even with a fully charged battery? Any fix, or is it dying?

This usually means the internal clock battery will no longer hold a charge. The only real fix is to open the camera up and replace the internal battery. The battery is usually soldered directly to the mainboard and can be difficult to replace.

internal battery is bad

The good news: loosing date and camera settings everytime you turn the camera off is as bad as it gets, everything else should continue working.

The only problem that I'm aware of is that a faulty internal battery can cause the main battery to drain rather faster than usual … that's what happens with my K-01 anyway!

As others have said, the internal battery has croaked, and is not especially user serviceable. My experience with this was with a K3 that I let sit for an extended storage period with no main battery inserted.
Live and learn. Don't leave these cameras without a main battery in them and make sure that battery is taken out and recharged often enough to not go dead as they can also lose so much charge that they can become unusable.

My Q-7 specifically asks the date/time almost any time I change the main battery, so I simply have my iPhone at hand any time I do that change. It is a minor inconvenience - if this is as bad as it gets, I can handle that.

My K-01 looses the date/time when I remove the battery, but not between power cycles with the battery in it. I only recently bought it, then sent it off for IR conversion, but this thread got me thinking, will I lose other settings? If I set a custom white balance for the IR, or make other config settings, will it retain those, or does it reset all the settings as well?

It resets everything that is user settable. Date, time, custom user settings, whatever you can set yourself is gone, either back to a default setting or erased entirely.

Not on mine … just the date/time needs resetting, the info that's stored and maintained by the internal battery.
Other settings/configurations appear to be stored in flash RAM (or similar) so my frame numbers, Custom White Balance, previously used shutter speed, aperture, ISO etc. are all retained, assuming they are configured to do so in the Menu … see p195 in the Operating Manual.

That will teach me to read the manual....

thanks! The camera arrived early, so now I can test myself.

I'm not 100% sure Ifixed it, but...

When I had the problem of the dead internal battery/capacitor (which is it?), I set the "auto power off" to never turn-off and after a few battery drains of the main battery, it appeared to retain the date and time.

Like I said, I don't know if I fixed it, if the charge to the internal electron storing device takes a long time, or if the stars have aligned and all is well without respect to my puny efforts.

I regard the K-01 as nearly equal to my K-5iis, which is identical to the APS-c frame of the K-1.
And its cheap!

It's an internal battery!
I'd tried most combinations of battery drain and recharge, also using an external power supply and "dummy" battery, in an effort to encourage my clock to remember it's settings with the main battery removed, so far with no luck … I'll be trying this concept of setting the camera to "never turn off" with interest!
Thanks for the idea
