The lifespan of an e-cigarette depends highly on a number of factors, most importantly the type of battery the device uses and how the device is maintained.
##Type of Battery
An internal or “fixed” battery device will typically last 3 to 6+ months before you may begin to notice a decline in performance. This can vary based on usage and charge cycles.
Removeable, rechargeable battery cells, such as 18650 batteries, can last anywhere between 6 to 18+ months. Devices which require removeable batteries are recommended for heavier smokers, as they can be switched out more regularly to provide full battery life. These devices often fare better long-term because once a battery cell has lost its ability to hold a charge, it can be replaced and disposed of appropriately.
Most clearomizers use cotton to transport liquid to the atomizer. Over time, the fabric wears out, and residue can build up in the coil. A coil will typically last 1-4 weeks, but this lifespan is heavily dependent on usage. A coil’s lifespan can be extended by always letting your atomizer soak after filling the tank with e-liquid, and only pushing the firing button of your battery when you’re ready to inhale. This will not only increase life of coil, but also the quality of vapour.
Tanks can also be rinsed with warm water to clear off any e-liquid residue. This is most convenient to do when changing your coil, as the coil is already being removed. DO NOT rinse your coil under water; this can ruin the cotton and reduce performance.
Many tanks also have glass exposed, which can easily break if dropped. You’ll want to avoid dropping your e-cigarette, as this can damage vital components. You can also use a vape band as a buffer to protect your tank’s glass if dropped.
Taking good care of your batteries is also an important part of maintaining your device overall. You can find out more about battery care here.
