My usual practice with a new battery, internal or external, is to just charge it when I get it, so I know I'm doing my initial run with it fully charged. Just easier for me to estimate the vape time. (If it's internal, yeah, I'll probably power it up and test it a bit first, so I know it's working right.)
From your link, Sorrynomore, emphasis mine:
Lithium-ion is a very clean system that
should not need additional priming once it leaves the factory, nor does it require the level of maintenance that nickel-based batteries do.
Additional formatting makes little difference because the maximum capacity is available right from the beginning, (the exception may be a small capacity gain after a long storage). Nor does a full discharge improve the capacity once the battery has faded – a low capacity signals the end of life. A discharge/charge may only be beneficial to calibrate a “digital” battery; it does nothing to improve the “chemical battery.” (See
BU-601: Inner Working of a Smart Battery.)
Instructions recommending charging a new Li-ion for eight hours do not cause harm but this is “old school,” a left-over from the old nickel battery days.
