There is an article here, on the charging characteristics of
the batteries.
"Charging lithium-ion batteries"
http://www.batteryuniversity.com/partone-12.htm
"Lithium-ion is a very clean system and does not need priming as nickel-based
batteries do. The 1st charge is no different to the 5th or the 50th charge.
Stickers instructing to charge the battery for 8 hours or more for the first
time may be a leftover from the nickel battery days."
The charge state when the battery leaves the factory, is selected
for best shelf life. This article compares the shelf life at a couple
of charge states. The battery is shipped with less than a 100% charge
on purpose.

Since the battery is going to wear out in a couple years anyway,
might as well just use it and enjoy it.
If the battery terminal voltage becomes too low, the charger may refuse to
charge it. And that is for safety reasons.
