That’s because the chances of cheaper batteries exploding after overheating are highly likely.

SAFETY is an important factor to take into consideration when it comes to choosing batteries for vaping. Manufacturers have now started incorporating high-tech, top quality chipsets into the batteries. What these do is control the vaping mod’s temperature.

Best 18650 Battery 2019

And this is something I learned after spending several hours researching about and examining the best picks on the market.The OUTPUT is also another important characteristic of a 18650 battery. It is as crucial as safety.

So here are the ten batteries that we know you can rely on without a shadow of a doubt.

Samsung Li-ion Battery for Electric Tools – Best Battery for Continuous Current

View Product On Amazon

The problem with most batteries is that they struggle to deliver a constant flow. But that’s not something you need to worry about with the Samsung INR18650-25R 18650 2500mAh 3.7v Rechargeable Flat Top Batteries. They offer maximum 20A continuous current.

The continuous current, when paired with the high drain quality of the battery, provides reliability and consistency. And the best part about the batteries is that they come with an outer layer coating. What this does is offer added protection.

So it comes as a surprise when you find out that the battery drains quickly. But the high-performance level makes up for this drawback.

The batteries don’t take too long to charge.

Excellent performance even at a higher wattage.

They produce punchy, solid bass.

Charge holding capacity is weak.

Now here’s a model that you can use for cloud chasing and moderate high-drain purposes. The LG HE4 18650 Rechargeable Flat Top Batteries offer maximum current discharge of 25A. And the continuous current it can provide is 20A. Both values are above average, which means competitive performance.

You’ll be glad to know that the LG HE4 work exceptionally well when mods drain increased amperage. Another thing to keep in mind is that their performance level is commendable. Especially in triple and dual settings!

Isn’t it fantastic when batteries have the ability to last for many days while also charging fast? If you agree with me, then there’s no reason to not opt for this pick. On a lower wattage, they can remain active for as long as three whole days. And on a higher wattage, the LG HE4 batteries offer power for over a day. And that too for intense vaping applications!

The materials used for construction are of the highest quality. And the proof of that is seen in the form of multiple cycles of discharge and charge. So don’t expect the performance level to deteriorate any time before at least 12-18 months.

The LG HE4 is excellent vaping batteries. The supply of current they deliver is quite hefty. Despite heavy-duty usage! And when batteries like these have the capacity to last, you can feel free to make them your default option.

The only negative feedback here is associated with the charge holding capacity. The LG HE4 18650 Rechargeable Flat Top Batteries lose charge rather quickly as time goes by. But to be fair, that’s the case with most batteries currently available.

The LG batteries offer a longer runtime.
The outer wrapping is tough and durable.

They produce punchy, solid bass.

Charge holding capacity diminishes with time.

18650 Battery Buyer’s Guide

best 18650 battery

The 18650 has now become the standard battery for vapers.

The chances of coming across this rechargeable battery in the tiniest box mod or the most complicated mechanical mod are pretty high.

You might think that these lithium-ion batteries are just like the regular consumer ones, but that’s not true. They differ regarding quality, voltage, capacity, and price. And that means finding the best 18650 battery can be quite a challenge.

Lithium-Ion Batteries: Why They Explode?

But you don’t need to worry about that anymore because I’ve created a useful guide for you. By going through it, you’ll realize how it’s wrong to believe that one size fits all.

Choosing the most reliable pick in the industry requires you to take several IMPORTANT factors into account. These include:

  • Operating temperature
  • Voltage
  • Current rating
  • Capacity

So let’s discuss each one of them below, shall we?

Capacity of an 18650 battery

The charge holding power of a battery is known as its capacity. The capacity also refers to how long you can use the battery before you need to recharge it. The best ones on the market are those that have a high capacity tag.


And the only way to determine if the high capacity label is genuine or not is to look for mAh. It stands for Milliampere-hours, and it refers to the amount of milliamps the battery draws per hour. This gives you an idea as to how long the battery will last.

Current of an 18650 battery

EBL 18650 Battery 3.7V 3000mAh Performance Li-ion Rechargeable Batteries with Stable Storage Boxes, 6 Packs

To prevent accidents from taking place, you need to give the safety factor its due importance. Determining the box mod’s current is a simple task as it comes with the specifications. Most of the traditional box mod kits fall between 1 to 45 amps of output current.

So keeping this in mind, an 18650 battery with 20A current rating seems like an ideal choice.

These batteries have a sufficiently high Milliampere-hours (mAh) level of 3000. Since the majority of the box mods require two of these kinds of cells, the total current rating becomes 40A.

Voltage of an 18650 battery

Voltage does the job of transferring the much-needed current of the box mod to its coil. This is why you need to know and understand your device’s specific requirements.

When using a mechanical version, this process is even more important. That’s because of the voltage, in this case, tends to deliver everything to the coil. So if the voltage is higher, you might get a stronger hit.

The current of batteries doesn’t decide the voltage capacity because there are batteries with different voltage but similar current ratings. So what you need is a battery with a higher voltage that runs for a longer time. And this applies to both regulated and mechanical devices.


The most efficient way to go about this is to select the 18650 battery that offers a decent capacity and high current rating. These are the ones that perform well at low-temperature levels, which means higher voltage.


Operating temperature of an 18650 battery

Many of us don’t take this factor into account whereas it’s considered to be a crucial one. The temperature that the battery runs at is a huge safety concern.

On top of that, overheated batteries also tend to cause damage to its charging cells. And this messes with the battery’s durability.


Batteries that overheat too often require replacement. You should take this as a warning sign. More often than not, overheating is the battery’s way of telling you that it’s either become too old or damaged.

Lower operating temperatures are suitable for advanced vapers. Because you obviously don’t want to go through the trouble of using high resistance coils or lowering the level of power.

And these are things that you might have to do if you opt for anything other than low operating temperature.
