to use a android aplication called electrodroid, wich is an app that has several electronic resources and calculators, and one of them is a extensive table of diferent cell coin batterys with their size name, chemistry, physical size and nominal capacity, u need a electronic device that uses the android OS, cellphones and tablets are the most common. So if by the way uoflcards has such a device, he can simply install the app and get the information that he needs.
but this is my simple advice in plain english. and im free to post what ever i want in compliance with forum rules. maybe its better u read this 3 times.
