How long will the Lithium battery last? I am a heavy vaporer

[teddybear]

I have 2 batteries I am using both of them, switching off from one to the other.  Should I buy a spare or two in case one dies?     teddybear

Simple answer is 'Always have a spare', but most lithium batteries last for 500 charges, after a lil research I did, its 500 charges, full or partial, so basically, keep an eye on it.

I'd advise always having at least three - one to charge, one to use, and one in case

Atomisers and batteries are always a good investment....

Wonder how feasible it would be to have a belt-mounted lithium pack, for charging everything, from cellphones to e-cigs (bit Batman I know, but in my world would be very handy)

Duracell and a few other companies sell them already.

I bought one of these  to charge my 901s (except they used to be silver instead of black)

I know how long they're supposed to last but in my experience, a bad one comes along once in awhile and only lasts a few charges.  I had an atomizer last me one day so what somethings supposed to do and what is does is a matter of quality control and other factors such as exposure, shock, heat and other varibles.
