* Do not use or store the battery in extreme heat, such as under a car window in direct sunlight. The battery could become overheated. This can also reduce the battery performance and shorten the service life.
* Do not use the battery if it gives off an odor, generates heat, becomes discolored or disfigured, or appears abnormal in any way.
* Do not use the battery in combination with primary batteries (such as dry-cell batteries) or batteries of different capacity, type or brand.
* Do not strike, throw or subject the battery to severe physical shock.
* Do not pierce the battery housing with nail or other sharp objects, break it open with a hammer, or step on it.
* Do not immerse the battery in water or allow it to get wet.
* As a safety precaution, do not remove batteries while being charged.
* Store batteries separately and don't let them mix with metal objects.
* Remove batteries from your e-cigarette if you plan to store it for long time.
* Store the battery at room temperature. The battery is a lithium-ion battery and will need to be replaced periodically.Read charging instructions before using.
* Do not short-circuit the battery by connecting wires or other metal objects to the positive (+) and negative (-) terminals, or reverse the positive (+) and negative (-) terminals.
* Over-discharging: It should be noted that a battery may become over discharged if not used for long time. Over-discharging may causes loss of battery performance and functions. In order to prevent over-discharging, the battery should be charged periodically and maintained between 3.6v and 3.8v.
