Charge the battery of the electronic cigarette.

Since electronic cigarettes work with lithium batteries, it is important that you fully charge the battery before using it. Many electronic cigarettes come with the battery charged partially or completely. Place the battery in the charger and wait for the charging signal to appear or for the light to turn on to make sure it is ready to use. [4]

Most electronic cigarette batteries are rechargeable and can last up to 250 to 300 uses. Batteries often last longer when recharged and used on a regular basis.
Avoid putting the batteries in heat and in direct sunlight. Do not wet or drop them often against a hard surface as this will significantly reduce their life.
Try charging the battery before it runs out completely and always keep your battery fully charged. Saving the battery with less than 50% charge may exhaust its long-term use.
