Battery Drain on Pixel Vertax Grip for 5D3?

[kevl]

Canon says not to store batteries in the camera or grip when the system is not in use in the manual shipped with the 5D3 because of battery drain. In fact is says to leave the batteries in for no more than 24 hours prior to a shoot.

Perhaps the drain that is been seen is excessive, but is it really an issue? If you're not going to use the camera for 5 days take the batteries out like Canon says you should.

The drain with the Pixel Vertax grip is real, and they've since acknowledged the issue. I wrote a blog post on my site specifically about the problem and the resolution:

Pixel has fixed the problem in newer grips. If you have a grip with the battery drain problem, simply contact them for a replacement.
