Sorry about the multiple threads, I did a quick search and didn't find anything. I'm just trying to figure out a bunch of the new features that I'm not familiar with.
On the 7D, you can register battery info. This seems to register a serial no. and remaining capacity. What is the purpose of this? Is it to keep track of which batteries are potentially empty? Obviously the camera won't know if it has been charged.
I notice it keeps track of 'health' of the battery, but does registering a battery help in this, or is that information come format eh battery itself?
I guess it requires a compatible battery with the technology built-in (i.e. official Canon LP-E6).
Which cameras allow you to do this?
