EVO solved that problem by saying how many puffs their atts are able to take. 12K, I think.
they might have altered it but it was 6K i think.. so far they are the only sellers that have come up with some figures but its still only half the story.. without my question one answered its meaningless..
lithium battery makers come up with a life span based on charge/discharge cycles..
their idea of knackered is when it reaches 80% of new capacity.. my 70% efficiency for atomizers was being kind..
plus using the battery makers figures an e cig battery could be considered to be knackered after as little as ten charge/discharge cycles..
the same questions need answering for batteries as atomizers..
what does worn out mean.. with batteries its charge/discharge cycles.. how many before the worn out stage is reached..
with atomizers it would be how much fluid is processed before the worn out stage is reached..
puffs could be used.. 8000 would be a reasonable figure for both atomizers and a pair of mini type batteries.. assuming a reasonable worn out figure is used..
70% of new would be reasonable..
these figures if used would tell a story no e cig maker (or seller) wants told thow.. less than two weeks use for a heavy user then it needs replacing..
many weeks use for a typical forum enthusiast who owns a dozen and never works any of them hard..
i know PC hardware enthusiasts (me every so often) who buy the latest $600 dollar graphics card as soon as one comes out.. ask em how long it lasts and they wont have the faintest idea.. they dont care.. how long will my overclocked cpu last.. dunno i chuck them long before they wear out..
the point i am trying to make is.. asking an enthusiast how long anything lasts is a waste of time.. they dont know and most dont care.. most posters on this forum are enthusiasts.. their new toy arrives long before their old one wears out..
i have said this may times before.. both e cig batteries and atomizers should be considered semi disposable items.. and yes that includes the ones that come with an SD before someone comments..
we say an atomizer will last a heavy user around two weeks.. the batteries using lithium battery manufacturers figures of 400 charge/discharge cycles should in theory last a year.. i doubt they will thow.. perhaps a couple of months or less on average.. say 60 charge.discharge cycles at a guess.. or 60 days..
