@sjct: $100 for a battery that only needs to be recharged once a year, sure. But, even a large capacity 18650 won't vape for a 10th of a year, more than a month on a charge. Depending on how much you vape, a full charge might last 1-3 days. Multiplied by ten, that's a month on the outside (light vaping) not a year.
On the other end of the scale, a standard 510 sized battery but with 10x the endurance. Now you're talking about a day or two of vaping on a single charge. At 10x the cost of a standard 510 battery?
It would be nice to have the option. And, if it were ever developed surely the price would come down over time. It's interesting to think of the devices which could be improved on, and new devices which aren't presently practical due to battery technology presently available.
I want a netbook or notebook I can charge before leaving on a week long vacation, and leave the power supply at home.

But, the battery might be the most expensive component, LOL.
