Just out of curiosity, Manufacturers say to do the big 12 hour charge on the battery before use. I would think that's just for overall function. If one want to get started right away, you could do a quick charge, right?
I mean, it wont hurt the battery or kill it's cycle life?

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. However, a full discharge/charge will reset the digital circuit of a 'smart' battery to improve the state-of-charge estimation

I agree that the 12 hour intial charge should not be necessary and that constant discharge with lithium-ion batteies does injustice to them. A great reference can be found at http://www.batteryuniversity.com/. I no longer wait till they are blinking and dead as according to Battery U, these lithium-ion's love to be topped off--just like the e-cig cartridges!! Hope this helps you and happy vaping
