my P18 will be here soon, also my switch is messed up really bad from dropping it, it wiggles badly
Ill test the batteries out in my new P18 if that doesnt work I may just get some 18650 batteries and go 3.7 vaping, or I may trade my P18 for a P10 when the new batteries can fit in the p10 if they give it 5+ hours that is
Woa, woa! please back your horse up
For starters, depending on your vaping style etc... getting 5hrs + out of a 10440 is reaching. I have seen reports on the 500mAh 10440, and folks can correct me if I am wrong, those ratings are inflated, because you physically cannot fit that much chemistry in a 10440 batt. 320 is the norm and even some suggest this is a tad high as well. In all honesty about 3 hrs is what is available from a 10440 batt, less using an LR atty which is strongly discouraged. A good rule of thumb is to expect 1-1.5hrs per 100 mAh, which of course decreases over the lifespan of the battery. I have found this to be pretty much a quick reference to go by and as Dave pointed out, I get 28-29 hrs on a 26oomAh an AW 18650.
Based on what we discusse last night, it may very well be your device that is causing this. I forgot one quesion. When was the last time you cleaned your Xhlaer? You button contact may very well be dirty (natural oxidation) and requires to be cleaned. If there is black on the tube, your tube and button are not making adequate contact, causing an overcurrent situation, = heat.
