    C200: Remove battery when not using the camera?

    For many camera's it is indicated in the manual to remove the battery when the camera is not used for a prolonged period (e.g. EOS R5). Nothing is mentioned about this in the C200 manual. There is also no protective cover for the empty battery slot in the camera. What do you advise? Remove the battery or not?

    I believe the general concern leaving a battery in any electronic device for extended periods of time is the battery could corrode but that seems only to be a problem with alkaline batteries. I've left my lithium batteries in the camera with no ill effects. The only other thing I could think that if the camera draws a small amount over long period of time the battery would lose it's charge, then when you need the camera in a pinch the battery will be dead you might not have the time to charge it. Again this shouldn't be a problem because you should always charge your batteries the night before a job.


      That is the way I work now: leaving the battery in the camera and charging the night before a job. So no reason to change that.


        Maybe the only other reason to sometimes remove it is if you use any bigger batteries that stick out to prevent any damage during transporting (if it's in a camera bag/case it should be fine).

        Once had a field hockey ball in a one-in-a-million chance roll to the camera - which was on the ground filming b-roll - hit the battery and rip it clean off along with some parts of the battery compartment, which was like $400-$600 (IIRC) to fix on the DVX100B (I was already transitioning to the HMC150 at the time so never ended up getting it fixed, and the camera still worked if you taped/rigged the battery).


          Many years ago, I used to sometimes leave batteries on cameras... but never again!

          The never again was after getting back to base after a couple of hours driving back after a shoot and finding one of the ops had left a high capacity battery on one of the cameras. BUT had forgotten to turn the camera off before packing it into its case. When I grabbed the case, a well sealed Pelican, I thought "What's that smell?" The whole camera case was warmish. I opened the case to be confronted with a blast of hot air that had a very electrical smell about it. That nasty something electrical is burning sense of smell. Sure enough, the camera and battery had got so hot the battery had swollen, split and was still powering the camera. I could hardly touch the camera body, it was that hot. I was able to turn the camera off and chuck it onto a bench. After it had cooled down, closer inspection showed that certain plastic bits had melted and warped. Worse still, the battery could not be removed. It had literally welded itself into the battery compartment. Long story short. The camera was a write-off. The sensor had got so hot that it developed the dreaded hot pixel syndrome of burnt pixels.

          Since then... never left a battery on a camera... and never will again.

            I've left cameras on a number a times after filming a performance, packed it up got home to pull the cards to discover a hot camera. No damage but I try to be more careful making sure the camera is off.


              There's also the danger of the camera being bumped ON, and thereby running down one of the batteries you planned to use, and/or causing more buttons to be accidentally bumped. Start recording? Delete a clip? Etc.

              Not likely, but possible.
