Like buying any other product, there a few things that you should look out for. In order to find the best 18650 battery for vaping, you will have to go over a few different metrics to ensure you’re getting the right one.
They are quite simple:
This means that when you are looking through the best 18650 batteries that cost should be on the bottom of your list. A cheap 18650 battery is always nice, as everyone likes to save money, but it is not always worth it. There are a lot of fakes going around (more on that later). These fakes can cause damage to your vape or flashlight. Resulting in you spending even more money on a full replacement, not just the 18650 battery.
Capacity on the 18650 battery you are looking at is important because it determines whether or not you will be able to power your vape or flashlight with it. Vapes often call for high capacity because they need a solid supply of power every time you take a drag. While best 18650 battery for flashlight will often need a low capacity combined with a high continuous discharge, so that is can stay powered on for a long while.
The normal mAh you will find on 18650 batteries is around 3500mAh. Make sure before you begin shopping that you take note of the required mAh for your device. Often just looking at the old 18650 battery still in your product will tell you what the required mAh is.
Long story short, “maximum continuous discharge” essentially means how long an 18650 battery can stay on for at a certain rate of power being drawn. Like capacity, you will want to take note of what kind of product you are placing a new 18650 battery into. The old, dead battery in the product will more than likely have a note of the maximum continuous discharge on the battery itself. The most common number for this is “30A CDR”.
With any popular industry, there are always bound to be cheap counterfeits. The best 18650 batteries will come from reputable brands. Only problem is that there can sometimes be counterfeits of those reputable brands.
Most batteries that come from China or Malaysia are known to be counterfeit in some way. These batteries can be extremely dangerous because they are often improperly marked. Often, they are marketed as something they are not. The most common case for when these batteries fail is they can start a fire.
Another scam to look out for when buying the best 18650 battery is to make sure that you are not buying old used 18650 batteries. This sometimes happens where old batteries are repackaged and sold as new. We strongly recommend that you only buy brand name and batteries that are made in America.
While Lithium-ion batteries are getting safer and safer every year, there are still a few safety measures needed to be taken.
The biggest problem with 18650 batteries is that they can still cause fires when they have either been short-circuited or punctured. For the latter, most people will never have to worry about puncturing unless they deliberately try. For short-circuiting, it is imperative that you properly store your batteries in separate containers. Short-circuiting can cause fires as well.
As is the same with all other batteries, there are very specific labels and numbers on the best 18650 batteries that you will need to pay close attention to. This is important because different flashlights and vapes call for different metrics and labels.
