the one problem with lithium ion is that their lifecycle begins on the date of manufacture not the date of purchase. If these were sitting in a warehouse for 2 years before you bought them they wouldnt last as long as if they were factory fresh. Its all relative and its not like they just quit working...they get to the point where you drain they really quickly then you have go buy some more. You are already taking spares with you.![]()
I don't think they're draining too quickly - yet... I think it's just that I chain vape (I was a 2PD + smoker) so I use them up. Usually the 1300 and the 1100 together will get me through one whole day, and then the back-up I use when they're charging. I've ordered two more so I have a back-up back-up if the back-up dies. I did a counter once and I puff 195 times in 2 and-a-bit hours, which is about 5 ciggys an hour, which would be about how I was smoking (that's a frightening thought)... granted I was at a pub when I did the test (I puff more when drinking), but bottom line is when I wasn't at work I did chain-smoke
