Hi All! I have the Canon 7D Mark 2 and I was out shooting at a local lake when I noticed my battery warning was flasing in the top display window. So I checked the Battery Info from the menu and it showed 8% remaining. I thought that was strange because the day before it was 68% (Shutter Count 286 and 3 green squares). I turned the camera off and back on and then the Battery Info showed 64% (Shutter Count 316 and 3 green squares). This has happened a few times. Has anyone else had this happen? I do use Duracell batteries (IMHO much better than Canon an 1/3rd the price) but I did not have this happen in my 7D.
Cheers.

Greetings,
The issue you are describing sounds like a communication failure. (Hopefully). When you use a 3rd party battery, unexpected behavior can result. I'm glad your duracell battery has provided a lower cost alternative for you, but this is the price you CAN pay when you use a non-OEM product.
I use both Canon and Watson batteries. I've never had a problem like this. Everyone here has different experiences / opinions about using 3rd party equipment. Most however, will tell you to use OEM for the best performance, reliability and safety for your camera.
Best way to fix it. Use a Canon battery, or at the very least another battery that might not exhibit the behavior.

It is a very slight possibility that the Duracell battery is the problem but I doubt it, because I use Canon as well. I'll give the batteries and compartment a good clean and see what happens. I have never had issues with using Duracell batteries for over 7 years. They are very reliable highly recommended and I get more shots than Canon batteries so I won't be changing any time soon. Thanks for your reply. Cheers.

Go back to Canon brand battery. It is possible to damage the camera with the wrong battery. Perhaps small but not a risk I would take.

I won't be going back to Canon thanks. Duracell are fantastic batteries and better than Canon.

You're right, everyone has different opinions and stories about third party equipment, but I get better results with Duracell and used them for 7 years without issues. I know of guy who had failures with a canon battery so I guess nothing is perfect. I do honestly think that the camera system has a fault but as above I'll give the batteries and compartment a good clean and see what happens. Thanks.

"I won't be going back to Canon thanks. Duracell are fantastic batteries and better than Canon."
Obliviously not or you wouldn't be asking a question here.
"... I get better results with Duracell and used them for 7 years without issues."
Again, obviously not and no issues until now!
It's your choice.

The issue wasn't with the Duracell batteries. I cleaned the battery contacts and battery compartment and all is good again. The original Canon battery that came with the camera is already showing only 2 bars in the recharge performance (2 years old) and after only a 38 shutter count is at 78% remaining capacity. The Duracell (7 years old) has 99% remaining capacity.
To me it's a no brainer. IMHO, because it has "Canon" on it - doesn't make it better. Duracell is a reputable company and its products are regarded as having excellent quality. I was actually hoping someone else may have had the same issue, but my problem must have been a one-off. Thanks for your replies - appreciated. Cheers.
