M6 Mark II Help with internal battery question

djjoonie — Tue, 06 Jun 2023 19:46:24 GMT

Hello all, i have m6ii but the date and time resets every time i swap the battery. if i swap it within a sec, it doesnt reset sometimes. So my question is how come it only resets the date and time if its the internal memory battery that is not working? the wifi, bluetooth settings and all my camera settings are all intact even if i leave out the battery for much longer. I already tried the clear all settings on p mode m mode video mode etc. please help! thank you!

I think most devices that can handle being without power for a short time have a small, internal battery to maintain essential functions, like remembering settings and keeping the TOD clock updated. However, if that battery goes bad, then even those basic functions are going to start failing. It sounds like that might be what you're encountering. In some devices these are basically watch batteries that can be changed by opening up the device. But I have no idea what the M6 has. (Or any modern camera, for that matter.)

EOS M6 mark II loses time/date every time I remove the battery. I got cost estimate for more then 400 $ from canon service support. Maybe you know another way to fix issue?

thanks

I remember one forum member fixed a similar issue by resetting all camera settings and custom settings back to default, but I don't remember which camera he had. Maybe worth a shot,

Did resetting to default help your issue?

No,
looks like I have to find the way to charge main battery via usb-c port. To avoid to remove main battery.

thanks

Looking through this forum, and considering my own experience, I am starting to conclude that this is an M6 Mark II design flaw. I've only seen this on older cameras and devices that had a user-serviceable battery you could change. I also believe there is no store of repair parts that Canon could fix this with, so what happens is that you wind up buying a refurbished EOS M6 Mark II. It hasn't happened on my refurbished one, but ... we'll see.

That works, by the way. and it's a decent workaround -- the problem is that the batteries are not particularly large, and it's easy to wind up needing a battery change during a shoot. You /could/ use one of those power bricks, I suppose. None of these solutions are ideal.

I tried the quick battery swap out procedure until I became very proficient at it. It NEVER worked!

We are doomed to live with resetting the date and time with every battery change. Frustrating.
