It doesn't happen every time I change batteries - the main battery - it's happened maybe 3 times since I got the camera a couple weeks ago. The date/time battery is rated for 5 years and I assume it's the original.
Only thing - I figure when a battery dies it dies. But I can set the correct date just fine and it'll stay for...a few days? a week? I don't know it's pretty random.
Is this the sign of a failing battery you think?
(it's the 5D not the MkII)
Thanks you guys!
There is a secondary button cell, for date / time. Replace it. see pg 41 0f your manual.
I was asking if this symptom sounds like a failing battery...

Thanks you guys - will p/u a replacement today, hopefully that'll take care of it - a CR2016.
just seemed strange the way it's failing...
Seems pretty normal. It happens once in a while with your pc as well when the battery of the motherboard dies and your bios is reset every time when you totally plug-out your pc.
At least I hope it solves your problem, but I'm pretty confident that it will []
Yes sir-ee! Replaced the little CR2016 and I didn't even need to reset the date - put in the new battery and the correct date was already there - somehow.... I thought for sure I'd have to set it manually...
I just love this 5D! []
Great! [
