You should never leave a battery fully charged... you want to immediately use it and then place it in storage mode when you're done.
Full charge is around 4.2V
Storage is around 3.8V

Batteries that are going to be left at "Full Charge" for phones, laptops etc are considered fully charged at 3.92V which is essentially storage mode
