E-cigarette Battery Maintenance

Keeping up on your battery maintenance is absolutely key to any vaping experience. Without a functional battery, your e-cigarette simply won’t work, so it’s important to understand how to use your battery properly. Here we take a look at the best ways to maintain your battery.


Just like a mouthpiece and clearomizer, batteries need to be cleaned regularly to ensure that they are working properly. Dust and dirt can find their way onto the battery fairly regularly, especially if you carry around your e-cig in your bag or pocket - so maintenance is vital.

The terminal is the most important part of the battery from this perspective, as this is the only exposed part of the device. This means that if anything gets inside through this port, it will be tough to get out, and may affect the performance of the battery.

Cleaning the terminal regularly ensures that when you screw the battery onto the clearomizer or tank, dust isn’t forced inside the device. The best way to clean the terminal is with a cotton swab, as this can be used to gently scoop up any debris inside the opening without the risk of harming any part of the device itself.

Holding the cotton swab like a pencil, swirl the tip around the terminal and scoop out any stray dirt. Make sure to thoroughly clean the inner walls of the terminal as dirt can often get trapped here when the battery is screwed back onto the clearomizer or tank. For this reason, it's also a good idea to check if this part of the e-cigarette has any dirt when unscrewing the component parts.


As the previous section implies, one of the best ways to keep your battery working at full capacity is to keep any dust or dirt out of the terminal. One of the easiest ways to avoid this is by storing your battery correctly. By keeping your battery in a secure place, it is less likely to accumulate any debris. This will also help protect your battery from any damage.

If you are using the blu PRO™, it is still worth finding a safe place to store your battery and a secure means of carrying it around with you. At home, a simple solution could be to designate a particular location, like a drawer, to keep it in so that you aren’t tempted to leave it lying around. Some vapers have even used a glass to store their vape pen in the same way that you might store a toothbrush. When you’re out of the house, make sure that the battery isn’t left at the bottom of your bag or purse, as this may lead to damage. Try to find a separate compartment or pocket that your e-cigarette can sit in by itself.

It is also worth noting that to keep your battery working properly, it should be stored away from direct sunlight and at room temperature.


A vaper’s worst nightmare is being out and about only to realize that their e-cigarette is out of charge. It is worth making sure your battery is charged before any trip out, as letting the battery run completely dry too often can affect how it performs.

But on the other side of the spectrum, it's also important not to overcharge the battery. While it may be tempting to leave an e-cig to charge overnight, doing this too often to the battery may run it down in the long term. It should usually take around 1-3 hours for the battery to fully charge.

All blu® devices indicate when they are fully charged, either when the tip begins flashing or when the light on the USB charger turns green. By keeping an eye on these indicators, you can ensure that you don’t accidentally overcharge your battery.
