E-cigarette batteries, like all lithium ion batteries, are not designed to handle extremes; whether it’s weather or humidity, they really don’t tolerate dramatically high or drastically cold temperatures well. So, if you find yourself living in areas where temperatures are known to hit extremes; hot or cold, with the possibility of severe humidity, (you know, basically anywhere that does not include perfectly moderate, dry conditions) the following info will surely be to your benefit.
Heat is particularly detrimental to the lithium ion batteries of electronic cigarettes. Some of the common issues known to arise from exposure to extreme heat include sudden halts in performance, the device failing to work, damage to the device, melting, bubbles, bulging, warping, expansion, contracting, the presence of smoke (not vapor!), sparks, flames, and even the possibility of explosions in the most rare and isolated incidents!
One thing to keep in mind about temperatures and your e-cigarettes is that extremes in temps can happen anywhere, and at any time. It is not a strictly a situation you’re going to run into exclusively by leaving your device in your car, parked in the sun, with all windows rolled up. Obviously, that’s a recipe built for disaster, but consider your back porch, an enclosed bathroom with the shower running, a sauna, your pocket if you’re outdoors on a hot, sweaty day; these can be everyday situations depending on your location, so in terms of the long-term usage of your e-cigarette batteries, consider it part of the package to keep the effects of the temperatures in consideration. Room temp is best, if you’re ever unsure!
The bottom line with e-cigarette batteries is that if you treat them properly, maintain a good regimen of care, they will last an exceptionally long time and will perform completely up to the standards you expect. However, considering all lithium ion batteries, e-cigarette or otherwise, are sensitive to temperature extremes, do your very best to keep them in moderation. Consider your e-cigarettes an investment; make your money go as far as you can.
