The most common and cost effective eGo-T battery on the market, available on it's own or with various add-ons up to and including a full blown starter kit.

A fresh 900mAh battery will last me (a heavy vaper) approximately 8hrs.

Very good value for money, so these are especially suitable to those just starting out with eCigarettes for the first time, why not have a go at giving up smoking for not much more than a packet of cigarettes?

These are the exact same kits I used to give up smoking myself several years ago, it worked for me so it can work for you... Still requires willpower :)

IMPORTANT NOTES:

These batteries are not designed to last forever, they are cheap and cheerful and for this reason are guaranteed only for 90 days.

If you get on ok with vaping as an alternative to smoking, always best to have spare batteries so you don't have an excuse to slip back, let's face it they're cheap enough!
