In fact, these disposable batteries can last for between 300-500 cycle charges, which translates into anything between 1 and 2 years. The longevity of 18650 batteries means that they are highly recommended for vapers who do not want to worry about buying a new power source every three months or so.

There is some variation in the time it takes to charge each different brand in our collection. However, vapers can typically expect this type of battery to take around 4 hours to charge in full.

Always stay within sight of the battery and ensure that you remove it from its vape battery charger as soon as it has reached its maximum capacity.
