This is quite possibly the most useless piece of documentation I think I’ve ever read. This is from the packet which came with my new Macbook Pro laptop battery.
For information about installing or using this product, including important safety information, refer to the documentation that came with your computer.
Really? You package a document with every laptop battery that tells consumers that in order to find out anything about the product they just purchased, they need to refer to a totally unrelated document (which chances are, they don’t still have)?
