M6 Mark II Help with internal battery question

[djjoonie]

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!

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.

Greetings TheHammer,

The camera's internal clock uses a small built-in rechargeable date and time battery that charges automatically whenever a main battery is left inside the camera. Because your clock is resetting during a battery swap, it probably means that the internal date and time battery has dropped below its necessary voltage and can no longer hold a charge. Try inserting a charged battery pack into the camera and leaving the camera turned off for at least 24 hours to see if that gives the internal battery a full deep charge. In case the time still resets then means the internal battery has reached the end of its lifespan. We would suggest on sending the camera to our facility to have it replaced.
