Read the article: They authenticate specific battery serial numbers, rather than type or producer. That means they authenticate if a given battery is the specific battery inserted at the apple factory. This, of course, also authenticates the type and producer, so they could allow fast charging on replacement batteries, yet they choose not to allow any replacement at all, not even with batteries from a discarded equivalent equipment. Again, if the intent is to protect against defective batteries this seems a very strange way to go about it. This specifically disallows replacement parts. Any replacement parts, no matter where they come from.
