Query: These batteries wont work in most devices

Turns out these batteries are only rated for 1.2v instead of the standard 1.5v. What does this mean? Your camera wont turn on; your Wii remote wont operate and your wireless mouse wont work.Unfortunately due to amazons lack of product labeling you may purchase these batteries only to be very disappointed.
