The best way I've found to clean the threads on an 808D-2 auto is by using 'applicators' I found in the cosmetic section of Wal-Mart -- they look a lot like Q-Tips except they're not as fluffy and one end is pointed while the other is flat. Dip the pointed end in iso-alcohol, wipe around the center contact, set battery aside to let it dry.
To those who've co-opted this into a soapbox for manuals: Get a life!
Cut-and-pasted from another thread (because I'm too lazy to retype it all):
Caveat -- I vape as an alternative to smoking, not as a drug delivery device, so my use/needs/wants may be different than many on this forum.
I tried manuals. They were clumsy and not worth the effort.
Also, manuals are dangerous:
1) Since most automatics now use air pressure sensors instead of microphones, they don't turn on at odd times. Manuals, by their nature, turn on whenever the button is pressed, whether it's because you're taking a puff or if they're in the back pocket of a pair of jeans, or dropped between the sofa cushions, or anything else that involves more pressure than a fat fly landing on it. Automatics need a cutoff to preserve battery life. Manuals need a cutoff to prevent starting fires. The common term is "hot pocket."
2) Whether automatic or manual, there's always the danger of a steam bubble forming on a coil. When it happens with an automatic, it'll shoot a drop of scalding liquid into your mouth, causing a small sore. When it happens with a manual, it sprays wherever the PV is pointed. There are no documented cases, yet, of someone losing their eyesight, but there have been many close calls. I can't find my bookmark for it, but there's even a video someone on this forum posted of such a bubble-burst hitting them in the face.
3) Battery explosions happen far more often with manuals. The causes are not well know Sometimes it may be because the button is activated when it's on the charger; other times it may be just because manuals are, by their nature, often more cheaply made than automatics. If you look through the forums for incidents and/or videos of battery explosions, you'll see that they're almost exclusively manual batteries.
4) Using an automatic leaves your hands free. You can hang it off the corner of your lip, like a cigarette, and vape without effort. A manual requires at least one hand, which means that when you're driving, working on machinery, or doing anything else productive, you're compromising control of what you're doing every time you take a puff.
Bottom line -- if you're looking for an alternative to smoking, choose an automatic. If you're going to be fanatic about needing a drug delivery device, you'll probably need a manual.
