Everything You Need to Know About 18650 Batteries

Do you have a device that takes external batteries? Are you thinking of buying a device that takes external batteries? If so, you might be wondering what those external batteries are and how to take care of them. Today, we’re going to be looking at 18650 batteries, what they are and how to make sure you're not buying a fake battery.

What are 18650 Batteries?

18650 cells are commonly used with external battery devices, they are rechargeable lithium ion batteries. These types of batteries can be found in all sorts of electronic devices, from phones to cameras and in this instance - external battery vaporizers like single and dual battery mods. 

How Do You Know It’s Not a Fake Battery?

Yes, the same way people sell fake sneakers and purses, people sell fake batteries. It’s not uncommon for people to buy cheap batteries and re-wrap them to look like official batteries and sell them on places like Amazon and Ebay. 

These batteries are going to underperform and cause a risk to your safety. Batteries have different voltage outputs, different numbers of cells and different ratings. This means that one of these knock off batteries could ruin your device and pose a fire hazard if the battery isn't suited for the power that the device is running.

So how do you know you’re getting an authentic battery? One of the easiest ways to make sure you’re getting an authentic product is to go through a trusted retailer - even if you might see what you think is the same thing on Amazon for a few bucks less.  

What is Proper Battery Safety?

Just like any other kind of device that produces electricity, there are certain precautions you should take to protect yourself and to help keep your batteries performing the best they can for as long as they can.

Never use a battery that’s damaged in any way - like a dented battery or a torn wrap.

This poses a safety risk to you and can also damage your device. If your battery is damaged, dispose of it by bringing it somewhere that you can dispose of electronics or give your local vape shop a call and see if they can dispose of batteries.

If you use a dual battery mod, make sure to marry your batteries.

This means that you always use the same pair of batteries at the same time, and charge them at the same time - they are never to be used or charged apart. This ensures that you aren't putting too much strain on one of your batteries and helps them last longer. 

The best way to charge your batteries is through an external battery charger.

Although many devices have the ability to charge your batteries with a cord like you would an internal battery device, this can cause your batteries to not fully charge and strain your batteries causing them to die out sooner. Furthermore, if you use a proper external battery charger you can avoid over charging your batteries to help them last longer.

Never carry loose batteries in your pockets - always use a battery case.

One of the biggest pros of external battery devices is being able to swap out your dead batteries with fully charged ones instantly. That being said, if you’re going anywhere with your batteries or storing them you’re going to want to use a silicone or plastic battery case. This helps prevent the batteries from connecting and posing a fire risk and makes sure your battery doesn't get dented and the wraps don't get damaged.


There are so many pros to using an external battery device, but it’s important to protect your investment! By using proper battery safety and understanding how to take care of 18650 batteries you’ll be able to extend the life of your device and have a trouble free vaping journey!
