Hey everyone, I picked up a seemingly brand new battery off of FB marketplace and have charged it up twice, both times I've used it, my 1DX Mk2 cannot focus and the shutter does not engage at all - I can manual focus but AF is almost unavailable. Has anyone encountered this? The battery is practically new and has been calibrated.
Does your other batteries work in camera and the camera function correctly??? This is a weird issue, normally the camera will simply not start if there is not enough power. I would expect the camera to be the issue if it is shorting out and not triggering the shutter. The answer to if it operates fine with other batteries is very important here to troubleshooting this problem.
Yes, all my other batteries work perfectly fine. I spoke to a fellow 1dx MK2 owner and he says he also has some duds that do the same to his camera.
Very interesting behavior for sure, I have only seen my different 5d models either work or not work with a battery. Did you buy a trusted 3rd party replacement model? At this point I would imagine it is frustrating getting replacement batteries for a 20 year old camera, the NP-e3 i think was probably retired ~12 years ago so I cant imagine any canon brand ones even working well sitting unused that many years. I normally shy away from 3rd parties as they don't always play nice in these higher end bodies, but I imagine for holding a charge proper you almost have to pivot to something still in production by another company.
The battery I bought was probably 2-3 years old with minimal use, only paid $100 and it was a legit battery. Not too concerned but just annoying having this happen.
Actually what i was trying to say is the last round of manufactured batteries are a decade old from Canon from what I have read, they have not made them for years, some 3 parties may at least have continued production for some time longer to supply when canon stopped. Sitting unopened not used could kill a nihm all on itself, they have a practical shelf life of maybe 5 years. Semi regular charging is probably keeping your old NIHMs alive. Canon quickly moved to Lithium in the mid 2000s on the next round of cameras as they are more resilient to aging.
