Canon is rumored to be upgrading to the LP-E6N starting with the 7D MK II. You can bet that they are stepping up their anti-counterfeit campaign and making it tougher to counterfeit the Canon battery code.
As I understand it, a message will appear asking you if the battery is labeled as a Genuine Canon battery. If you say yes, that means you have a counterfeit battery, and the camera will not start up. If you say no, which means its labeled as a third party battery (Wasabi, for example), then you will be asked if you take responsibility and want to use it.
