Generally, the shelf life is two years if unopened, and one year once opened.
However, you should always refer to the specific product you purchased for the exact details. It is recommended that you avoid buying bottles that are too large; sizes of 10ml, 20ml, or 30ml are usually sufficient.
1. Storage. When storing an e-cigarette, one key principle should be observed: if there is e-liquid inside the atomizer, the mouthpiece should be positioned facing upward. If the atomizer is empty, storage is more flexible; however, it is still best to avoid storing it upside down to prevent any residual e-liquid from leaking out.
2. Battery Maintenance. Battery maintenance is crucial, as the battery is a primary component of the e-cigarette. Ideally, you should wait until the battery is fully depleted before recharging it. When charging, complete the cycle in one go without interrupting the power supply midway. Once fully charged, remove the battery from the charger within 30 minutes. If the e-cigarette will not be used for an extended period, be sure to turn off its power supply (typically done by pressing the activation button five times consecutively within two seconds). For long-term storage, the battery should be removed from the device and placed into a charger-such as the VC4S-using its "Storage Mode" to adjust the charge level to 3.7V, thereby ensuring safe, low-temperature, and dry storage conditions.
