Lithium ion batteries first charge

According to an article at http://www.batteryuniversity.com/print-partone-12.htm

Unlike nickel and lead-based batteries, a new lithium-ion pack does not need cycling through charging and discharging. Priming will make little difference because the maximum capacity of lithium-ion is available right from the beginning. Neither does a full discharge improve the capacity of a faded pack.

So really the "full discharge and initial charge of 8 hours" were obsolete practices of the Nickel Cadmium batteries era.
