Fully charging a new digital camera battery before first use?

[lili5689]

I recently got a new digital camera. The minute I got it I brought it home, put the battery and memory card in, and turned it on and played with the settings and took a few pictures. Only then did I notice the tiny writing on the box saying "Must fully charge battery before initial use." Im wondering if I could have caused damage to the camera or battery by turning it on and using it for a little while before fully charging the battery?

Lithium-Ion batteries are shipped charged to ~80% full. You can use it straight out of the box until it needs recharging.
