RC Helicopter - First time charge?

Hi, with a new RC Helicopter should it be charged the first time, as when I turned it on it seems to have already been charged?

And should I like charge it extra longer?? Can you give me some tips on how to do the first charge, shall I charge it like normal…or use up the battery that is already in it from the factory? HELP

this is it

Charge it like normal. Most rechargeable batteries come charged a certain percentage (40% is most cases) because it maximizes shelf life. You still need to fully charge before beginning normal use.
