The charging time of disposable electronic cigarette batteries is calculated according to the in-and-out current, such as a 650mAh battery rod, the input current of the charger is 220mAh, then it takes 2 and a half hours to 3 hours to fully charge. The service life of a fully charged battery is calculated according to the output current. Generally, the output current of the battery is constant, so the higher the current, the longer the battery will be used.
In addition, the use time of the electronic cigarette battery is related to the quality of the battery itself, and the quality of the battery depends on the material of the product and the production technology, and the battery with good quality has a long service life and stable service life.
