What everyone ought to know about e-cig batteries and heat?

Lithium-ion batteries perform at their best (and will last a whole lot longer) if they are kept at temperatures between 14°F and 86°F. If batteries are too hot (or too cold), they can lose their effectiveness or even quit working altogether.

That said, the number one cause of battery problems is too much heat. When a battery gets too warm, it causes them to drain faster than they normally would. For that reason, you NEVER want to leave any electronic device with a lithium-ion battery in the front seat of a hot car. Ideally, you should think of you electronics as if they were a baby or a dog –if it's hot outside, don't leave your e-cigarette in the car.
Batteries are also affected by humidity and other weather extremes. An e-cig battery damaged by heat can: stop working, bulge, bubble, melt, damage your device, smoke, create sparks, create flames, expand, contract, and in very extreme cases, even blow-up.

Furthermore, weather extremes can occur almost anywhere and at any time. Some examples of areas to avoid bringing lithium-ion batteries are in a non-temperature controlled room, in a closed bathroom with the shower on, in a closed car on a hot day, in a steam-room or a sauna.

Think your e-cig battery is safe in the cold... think again.

Extreme cold can affect batteries just as extreme heat can. When exposed to frigid temperatures, the internal components expand. Remember, a weather extreme can occur when temperatures are within the range of the device's specification. The relative humidity can increase the ambient temperature beyond the norm.
