Have you ever had this on the GH4 ? "Set Clock" on power on. Built-in battery dead?

Hey all,

Any time I leave the GH4 without battery for a few days, once I turn it back on, the time/date has been forgotten.

The manual says to leave a battery in the cam for 24 hours to recharge it :

I have done that, but the phenomenon still happens a few days later (not 3 months!).

In case this built-in battery is actually wasted, can one replace it ?

Thanks!

It happens to me with my G7 and GM1 that both were sunk to a lake. Whenever I change the battery, I need to set the date. The GM1 also slowly drains the battery even if it is not on, so I don't keep the battery in and need to constantly change the date. It is my 3rd/4th body anyway, and I rarely use it, so this is not a real issue to me.

It's a shame to hear that internal battery cannot be replaced.

Keep the battery in. It does not take many hours to charge, not days anyway, so it should not be a problem, unless for some reason it is.

Had it happen on other cameras. Tend to keep my cameras here for a very long time before a so called upgrade. The NEX-7 is over 6 years old as an example and the E-M10 is getting older as well now. So it wouldn't surprise me if it does happen to them as well.

Other cameras just don't seem to have an issue with that problem.

All the best and IMO, it's not that surprising. Maybe on a GH4 it is.

All the best.

Had it on my e-m5. I’d actually be surprised if these things had an internal battery. I’d be expecting a cap instead.
