In a technological world, it is nearly impossible to use a gadget without a battery. Like your mobile phones, laptops, computers, mp3s and other personal devices, your vape or electronic cigarette also has a battery, which is powered by lithium-ion, the most common type.This is because lithium ions the best providers of high energy density which allows portable devices to run on a single cell.

The topic of batteries, its caring guidelines and hazards has been one of the most popular topics when it comes to discussion amongst users and non-users alike. How can a vaper maximize its unit’s battery, without compromising his or her safety?

Here are some tips of how you can prolong its shelf-life, as well as ensure that it is safe to use all the time:


The first thing you should do before charging your unit’s battery is removing any attachment that come with it such as cartridges, cartomizers, clearomizers, atomizers, tanks, skins, and other accessories.

It should be general knowledge that you should only charge your battery with the charger unit included in your ecig kit and follow charging instructions to the letter. Using a third party-provided charger (the generic or unspecified ones) maybe risky, especially if it has a mAh rating higher than the total battery capacity. Experts really discourage charging using alligator clips.

Moreover, never use or charge a battery that has been damaged physically by dropping or bumping.

Once the battery is fully charged, disconnect it from the power source. Overcharging it can damage the battery, just like how it damages your other devices. Worse, it can even lead to explosions and fires.


Used or unused vape batteries have a shelf life of two to three years. Every single one will eventually expire, and it is not advisable to use an expired battery for your unit. However, to prolong the life of your battery when not in use, store it in a cool dry place at about 40 percent capacity. You should also disconnect the battery from the cartomizer or tank when not in use. Moreover, avoid exposing your lithium ion battery to heat, water or direct sunlight and store it in a place not accessible to children or pets.

Battery Safety

No matter how much of an expert you think for yourself, do not attempt to disassemble or modify your battery as the materials inside may be toxic when they come into contact with skin.

It is also a precautionary measure to never put your e-cigarette in your pocket as lint can easily penetrate through the small openings and cause the switch to malfunction or prevent air from flowing properly. At the same time, refrain and avoid using airtight skins or jackets and putting the battery on its pockets. Heat causes lithium-ion battery packs to degrade much faster than they normally would.

Worst case scenario: if a fire starts, call the fire department immediately. While waiting for help, you can try to put out a small fire by using a Class D fire extinguisher, dry sand or dry table salt.


Used up batteries should be disposed properly. After full use, your lithium-ion battery will eventually wear out. That being said, responsible vapers should never throw it down the trash bin like it’s any ordinary rubbish.

Batteries that end up in a regular landfill can leak into the waste stream and contaminate soil and water—just like any battery-operated gadget. Check with your ecig manufacturer if it offers a recycling program. If not, ask your city or state official regarding local policy on recycling batteries.
