I read that too. Did not work for me and several others who tried.
Should not be a factor in any case.
Interesting. Worked like a charm for me.

A while back I read online (it may even have been in here) that if you remove the memory card before removing the battery it fixes the problem. And it does.
I tried this, it worked, and I thought it was a nice tip.
In fact, it wasn't.
Because it works, weither the memory card is there or not.
And it works, with a fully loaded battery.
Then you can insert or remove the battery for a short period of time, and you keep the date setting (Q & Q7 for me). OK.*

I think that the fully loaded battery gives enough power to the camera (the internal battery of the camera?) for a short period of time, so the camera is able to keep the setting in memory.
But during a shooting session, if I change an almost dry battery with a new one, it doesn't work, and I have to set the date. (already with the Q and now with the Q7).
(and same thing at home, naturally)


*This doesn't work with every camera, because, I think, it depends of the "health" of the camera : Is that camera able to "borrow" some power to a fully loaded battery, or not ? (that is the question)

Please, check, and confirm, or not.

At another photography forum where I am a regular, someone stated in an authoritative fashion (yes, I know he may or may not know what he is talking about) that modern cameras have a small rechargeable battery which keeps the clock going during battery changes, but not much past that. I don't know whether he is correct. My experience, with both the Q-7 and the K-30, is that fits what I am seeing. Whatever is true, the system used by Pentax seems to lose power / length of keeping time without the primary battery as the camera ages.

Now, the thing I'm wondering is this: does what we are seeing mean that a Q draws a very very very small amount from its primary battery even when the camera is turned off? If so, what are the implications of that?

Possibly solution for losing time and date after battery change

Before changing the battery, leave the camera switched ‘on’ for a while (say 10 minutes). Than change the battery. Start using the camera more often. This worked for me on a Q7.

Welcome to Pentax forums and the Q. Your tip makes a lot of sense, and taking more photos is always a good idea.
Thanks,
