I treat any Lithium battery the same as I would a laptop battery for the most part. I'd recommend reading
BatteryCare - Proper laptop battery usage guide. Applies to laptop batteries, and references their software, but the theory is the same. It's the same with your phone battery now that I think about it.
My tips
1) Charge the battery, uninturrupted, to 100% when you first get it before use. Once it reports 100%, there's no point in keeping it plugged in, letting it rest after charging it cools down is beneficial but not worth being concerned about imo.
2) Avoid going <30% battery when you can. Charge more frequently, topping your battery off once or twice a day is better than one mega charge every 3 days for example.
3) If you're not going to use the battery for a long period of time (weeks, months), you want to discharge down to about 50%. Dont just store the battery at maximum charge, or at 5%.
4) AVOID HEAT, the hotter the battery gets, the shorter it's lifespan gets. For example, do not leave it in the car to bake under the sun.
Can't comment on recalibration as I'm only familiar with it on laptop & smartphone batteries where it corrects the battery's reported wear level so the software on the OS gives you accurate percentages, it does NOT extend the battery life so for an ecig it would be of little to no benefit.
