Do you always have problems with charging your e-cigarette? This article tells you how to charge it correctly

First of all, we must avoid the pitfall of “mixing chargers”. Many users use mobile phone chargers or power banks to charge e-cigarettes for convenience, thinking that "as long as the interface can be plugged in, it's fine." However, doing so carries great risks. “Different brands of e-cigarette batteries have different voltage and current requirements. For example, our brand of cigarette holders require a charging specification of 5V/1A. Using a 2A mobile phone fast charging charger will cause the battery to continue to overheat. In the long run, it will cause battery bulging and reduced battery life. Severe cases may even cause safety problems.” Sanlei’s technical engineers showed a set of comparative experimental data: the battery using the original charger can still maintain 85% of its initial battery life after 500 cycles of charging; while the battery using a non-original charger will drop sharply to less than 50% after the same 500 cycles, and may even bulge. The correct approach is: always use the original charger that comes with the product. If the charger is lost, you need to purchase the same model accessory from the brand's official channel. Do not use third-party chargers at will.

Secondly, pay attention to the choice of "charging time". Many users are accustomed to using their e-cigarettes until they are “completely out of power” before charging them, thinking that this can “activate the battery”. But in fact, the best time to charge a lithium battery is when there is 20%-30% power remaining. "Lithium batteries don't have a memory effect. Excessive discharge damages the electrode structure within the battery, shortening its lifespan," the technician explained. "Just like with mobile phones, frequently using the battery to 0% before recharging will reduce its durability. The same applies to e-cigarette batteries." He recommends that users develop the habit of charging as they use their e-cigarettes. For example, a 30-minute charge during lunch break will be enough for afternoon use. At the same time, the charging time should not be too long - most e-cigarettes take 1.5-2 hours to fully charge. When the indicator light turns solid (or green), it means it is fully charged. The charger should be unplugged in time to avoid "overcharging".

Furthermore, we must pay attention to the safety of the "charging environment". Many users charge their e-cigarettes while sleeping, placing them next to pillows or on blankets. This practice is extremely dangerous. "The battery will generate slight heat when charging. If it is placed on soft objects, the heat cannot be dissipated in time, which may cause the battery temperature to be too high and cause a safety accident." Zhao Kai reminded that when charging, e-cigarettes should be placed in a hard, flat, and ventilated place, such as the hard surface of a desk or bedside table, away from curtains, bedding, sofas and other flammable items. At the same time, avoid charging in high or low temperature environments - do not place it on a windowsill in direct sunlight in summer, and do not place it outdoors in winter. The best charging temperature is 15℃-25℃, which can keep the battery in the best charging state.

Finally, the "charging interface" must be maintained. After prolonged use, e-cigarette charging ports can easily accumulate dust and residual e-liquid, leading to poor contact and intermittent charging. "Weekly, use a cotton swab dipped in a small amount of medical alcohol to gently wipe the metal contacts on the port to remove stains and oxidation," an engineer explained, demonstrating the proper cleaning method. "Be careful not to allow alcohol to enter the battery compartment. After cleaning, wait for the alcohol to completely dry before charging to avoid short circuits." If the port is loose or deformed, do not force the charger in or out. Contact the brand's after-sales service immediately to prevent further damage.

Mastering these charging techniques will make your e-cigarette battery more durable and safer to use. In fact, many battery life troubles can be avoided through correct operations. Instead of frequently replacing batteries, it is better to develop scientific charging habits from now on.
