All these make a difference when answering the hard question of what the best vape battery is. Despite variations, we’ve managed to capture several factors that are in common.

They are the capacity, voltage, current rating, avoiding overheating. This info showcases how your 18650 battery performs; still, not everyone is literate to see the meaning behind the figures.

Even the experienced vapers sometimes get ensnared in the information ocean littering the packs and websites, not to mention the vaping newbies.

Do you recognize that feeling when fellow-vapers are going about the Watts, ohms, and amperes and you are only able to admit that your vape pen is black (pink, rainbow, or with a unicorn print) and nothing more?

Or when a seller guy tells you about bright characteristics of the super-cool and costly brand-new device, but you feel you are talking different languages? Then this article is for you.

But first, let’s take a bird-eye view on a build and operation of a battery.

What Is A 18650 Battery and How Does It Work?

Perhaps you have already met this indication 18650 at a battery description. These figures are a size classification. So, the 18650 battery size is 18 by 65mm. It is also called 18650 lithium battery, because of the chemical contents.

Every battery is nothing more than two metallic plates in a chemical substance called an electrolyte. The electric tension between the plates measures in volts. For instance, the pressure equals 9 volts.

This figure preserves till a vape is off. When the heating mechanism clutches to the battery, the current busts out and the tension inside drops.

As the volt power descends, the chemical reaction takes off, and the metallic plates start beaming electrons (charged elements) to supply the power. This flow of electric particles is current. Strong current means fast reaction which requires more volts to get produced for maintaining the pressure.

The high current caters for a faster and stronger heat up. Specifically, the same tension of 9 volts reaches your heating element faster. The devices with the adjustable voltage let you control the number of volts. It is done to beef up vapor or boost the heat up.

At some point, the ability to generate electrons maxes out, and the battery discharges. It happens if the source chemical elements come to the close and metamorphose into by-products. But it’s not the end for a 18650 rechargeable battery.

The process is reversible as some of the external electric power recovers the ability of chemicals to produce tension, as it comes about at a charge. The by-product or waste transforms into the source material over again. There is something magical in electricity, isn’t there?

Therefore, all the operating cycle is about using and restoration the chemicals inside the 18650 battery.

Realizing these fundamentals will shed light on such essential characteristics as a battery’s capacity, voltage, current, and temperature. The capacity is the ability of chemical elements inside the cell to produce the charged particles or in other words the amount of active source material. The voltage is the tension or the number of charged particles inside the cell, and the current is their flow.

Now, let’s see these factors one by one.

vape batteries image18650 Battery Capacity

As we have mentioned, the electrical elements inside the battery cultivate electrical tension. It remains stable when the device is inactive and alters as it is set to work. To hold off the drop in voltage, chemicals balloon particles, but they can’t do it eternally. The faster they beam; the sooner they die.

The flow of electrons (charged particles) is called the current and is computed in amperes or milliamperes. But it is not only essential to know the number of amperes produced but also the speed of the flow or in other words how many amperes go out in one hour. The indicator displaying this is called capacity.

What is mAh?

The capacity is the number of milliamperes that go in and out of the battery in one hour. So if you have questions like what does mah mean you now know that it’s a mere abbreviation and mah battery meaning stands for milliamperes per hour. The cell with a capacity of 1000 mAh delivers 1000 milliamps in one hour of use.

It also means that you can draw 2000 mA in 0.5 hours or 500 mA in 2 hours. Whatever the mode is, the battery produces 1000mA in 1 hour in the average. The more intense the setting, the higher amount of amperes you get, but the shorter amount of time remains because of the resource burn-out.

From the use point capacity stands for how long and intensively you can vape before the battery needs a recharge. We can draw an analogy of an empty juice jar. If power is juice, then the capacity is the size of the pot, when compared very roughly.

In this case, the more is good, and the higher the capacity, the better quality the battery is. High capacity means that a battery will last longer, and that is the necessary feature of the best vape battery.

There are devices that run at a capacity of 2500 or even 3000 mAh, which is a high rate available at the market today.

When the vape is on it won’t necessarily employ all the 6000 mA in 0.5 – cause vapes are usually set at a certain level of energy output. It hints at that at the same intensity of operation, the battery with a capacity of 3000 mA per hour will live longer than the one with a 2000 mAh indicator.

In this case, the best 18650 battery for vaping is one with the highest capacity cell. Isn’t it? Are any available at the market? Although such an option is desirable, this isn’t right because there are other important indicators to take into consideration. One of them is high current.

The thing is that batteries either have high capacity or high current. They can’t combine both. We shall clarify the high current rating later, but what is essential at this point is to celebrate fewer in a better way, or finding your golden mean in weighing the pros you get from capacity and current.

Keep in mind the batteries aren’t equally efficient all the time. In the course of use, the capacity decreases and the whole device operates worse. The good news is that if you treat your equipment with attention and care, avoid overcharging and over-discharging; the vape will hold the fort longer. It is also essential to use a compatible charger.

One more thing about a 18650 rechargeable battery. As you remember, a charged battery keeps the voltage level stable. The build of the cell makes it drain all powers to do it. If the charge drops and all the chemicals disintegrate, the level gets down to the last volt.

After that it takes much effort to lift the voltage from zero; moreover, some irreversible cracks crop up. If the tension amplifies, some irremediable chemical reaction comes off, and the contents of the cell go waste.

To conclude the battery capacity lets you vape longer without recharging. The best positions on the market are 2500-3000 mAh. The high capacity batteries cannot have a high current rating.

Current

The current is the flow of electricity out of the battery. It is needed to set the device to work so the higher the current, the faster and stronger the heat-up is. But not only the heater’s temperature rises, but also the temperature of the battery itself.

It’s great to have a significant current rating without overheating the battery, but that’s the hard aim to achieve. Whether using the regulated on non-regulated mods, the safe, high current rating battery is a challenge.

Except for that, there is another factor to count on. As we have mentioned, you can have only one benefit (a capacity or current rating). So the battery rated 3000 or even 4000 mA with the lowest temperature possible may deliver only 1500 mA per hour, meaning that you’ll possibly have to charge/change cells more often.

It is the price to pay for high current. To better explain this we shall compare the battery capacity with your money and the current with how fast you spend them.

If you are ready to pay them very fast (high current) – you can’t keep the same money long, your funds get over (the сell gets discharged). A vaper is similar to a hard shopper. It’s a very rough comparison, but it highlights the main point: do you need all the stuff you buy in the shopping fever, or you’d better save your money?

Or in other words, do you need all those features you get from the high current (fast and powerful heat-up), or you’d better stick to lengthy capacity?

Primarily, it’s up to each vaper’s taste and vaping mode. If you know your preferences, you know what figure you should take into account when choosing the best 18650 battery.

In opting between high current and high capacity, it’s always better to give high compromise.

A cloud chaser will choose a high current rating, like 30 amperes and that’ll be great for a one-time bright and powerful experience. But for others, it is sufficient to have 2500 mA cell with 2000mAh capacity.

In choosing the best vape battery one may come across an underwater current. Some companies give the best battery ratings on the package, possibly in the beginning of use or in the best conditions, but not in the every-day reality of a vaper. Buying a thing with the best label, you’ll find yourself replacing your batteries way too often.

Another indicator to take into consideration is the battery pulse rating. The battery pulse rating is the pulse duration in seconds, amperage of the pulse (how strong the current is), and the length of rest between pulses.

The current pulse rates on the market are 60 A 3-10 second pulses with 20-60 seconds of a break. Still, not all the manufacturers showcase this rating on the packages, so this indicator doesn’t always aid in the comparison.

Keep in mind that battery packs contain info about continuous and maximum current rating. The figure that matters is the continuous one. It is ideal when your battery reaches 30A or more.

The other numbers used to compare the batteries are the continuous discharge rating (CDR), maximum continuous discharge (MCD), maximum constant current (MCC). They are all the different words for the same name and are used to rate a battery’s capability.

Voltage

The voltage is another important indicator when buying the best 18650 battery for vaping and it’s also better to keep high. If we have compared the capacity with a jar, then energy is the air pressure in the balloon. The higher the pressure, the more air will leave the balloon at the opening.

In vaping terms, the high voltage means that a lot of power drives to the coil, and in the result, more vapor is created. On the contrary, low voltage means that less power goes to a coil, in the effect it works slower/weaker and produces less steam.

The vape mod batteries presented on the market usually run different voltage. If they drive the same amount of current when operating, the winner is the battery with the higher voltage as it will run longer.

Vapers like to have batteries with high voltage, as they provide a better throat hit – a feeling many vapers seek. Though this sensation hardly depends on personal preferences, the high intensity of nicotine sensation is called a hard hit.

To have it you either need a high-powered device or high-nicotine e-liquid. But the first variant is preferred.

Therefore a 18650 battery vape with high voltage is usually valued and has other favorable specifications like substantial capacity, high current rating, and running at low temperatures. And vice-versa: if the device has the enumerated indicators, then it should have a high voltage.

18650 battery image 4The Difference Between the Battery’s Capacity and the Battery Voltage

Not all the vapers clearly understand how these two work. Still, the right idea that would help to make the right choice when buying a vape.

As we have mentioned earlier, the capacity measures how long vape batteries will live after the charge. The vapes with a voltage that is not variable adjust to output 3.7 volts. So if the capacity is 1100 mAh these 3.7 volts will be output longer compared to the battery capacity if 180 mAh. They will both put the same voltage at some point, but the weaker one will discharge sooner.

You need the high current for a faster and stronger heat up. That would mean that the same tension of 9 Volts will get to your heating element faster. The devices with the adjustable voltage let you raise the number of volts produced.

Primarily if the granted result isn’t satisfying and you want more. At some point, the ability to generate electrons will exhaust itself that the battery will discharge. It will happen if the source chemical elements run out turning into by-product.

Therefore, all the operating cycle is about using and restoration the chemicals inside the battery.

Still, when setting the high voltage, you have more electricity out of your device. In this case, the current is the speed of the cars on the highways, and the voltage is the number of lines.

You can have one car leaving your city at 200 km/h, 2, 3, ten cars at the same time. The more cars will leave the town the smaller amount of them is left inside. So you have already got this: at high voltage vaping the battery will drain faster.

Temperature

When operating at high rates, the batteries tend to overheat. That negative phenomenon causes electric battery worn-out and damage to the device elements. Therefore, it is critical to have cells that operate at low temperatures. It will ensure the comfort of use as well as durability.

The vape batteries overheating is the primary cause of the early aging of the device. Therefore attention to the temperature inside your equipment is critical.

To eliminate the worn out the user can choose low-power settings of vaping, but still, it’s not the way out. We all want the best vape experience at the least risks. Therefore manufacturers invested much of time and effort in experimenting with materials.

There are some variants in shops to allow users to obtain cells with really low-temperature quality, so with a little bit of research, you can find what you want.

Another significant plus to finding a cold battery is the unpleasant feeling of the overheated device in hands. Not to mention that your device can even burst because of heat! When a device you put in a mouth is a potential bomb, the pleasure of vaping gets less notable in contrast to its danger!

Also, having the batteries that keep cool gives you more freedom in choosing the power settings you want to try.

We hope with the evolution of the vaping market the issue of overheating will vanish. But until then we do have products that aren’t that secure, and some attention to details is needed, even with the best 18650 batteries.

Price

The 18650 lithium battery prices don’t vary much, but it’s always better to keep the costs low. Isn’t it? Most batteries range between $5 and $15, so the difference isn’t impressive.

But it’s always important to compare prices up with your needs. The best vape battery should last at least a year and at the same time be able to provide you with a great safe vape.

Reliable Trademarks and Counterfeit

It’s already a tradition having the leading brands and hundreds of mimickers in every business and vaping is not an exclusion.

For now, the best companies producing high-quality materials are Samsung, Sony, and LG sometimes called the Big 3. These manufacturers provide high standards, thorough testing, and precise choice of the products they let to the market.

Still, it doesn’t mean that the products rejected in the testing process don’t find their way into the vaping world as well. Very often the bad batteries come into possession of less famous trademarks and get sold in another wrapping as unique solutions.

They even have guarantee badges proving their authentification. But these labels only confirm that an item doesn’t have exact market duplicate, it never means that it has passed all the necessary testing, neither that it meets high standards.

Low-cost devices usually run on such rewraps. It doesn’t necessarily mean bad quality, as some of them do just fine. Still, some of them can be a money waste or even dangerous.

Anyways, it’s up to each vaper whether to choose branded vape batteries or cheaper untested ones, but there is always the problem of counterfeit and forgery.

To be sure you avoid the letter we recommend buying your devices and spare parts from the attested vendors.

And now, let’s consider some factors that can bring your battery to an early death:
– You don’t stick to the primary safety rule: that is keeping the vape battery away from kids, pets, and fire. It’s obvious advice, that maybe even funny, but that’s not that funny as it gets swallowed by your dog or kid.
– You tend to overcharge. It may be a surprise to you, but the best power level is not 100% but 95%. If you keep your device on charge even after the indicator shows maximum, the cell gets ruined.
– Over-discharge. Many of us feel quite safe with the 15% charge, as it’s still far to zero. But in reality, letting the power indicator go lower 15% equals damage.
– You store the batteries discharged. The same thing: keeping the 18650 rechargeable battery unused for a long time, especially when the power balance is less than 70% equals to batteries death. To avoid this, keep your batteries charged and in a plastic case.
– You use a random vape charger. It may bring about a drop in quality and durability. Choose the compatible 18650 vape battery charger.
– You don’t clean your battery. It may seem excessive, but small particles of dust and grease can hinder the flow of current from the battery to the device contact, so regular brushing or rubbing on the clean cloth is required.

By avoiding all these mistakes, you can keep the device sound and run for a long time. And now let’s go through some useful tips for battery maintenance.

– The initial charge should be full. It will ensure a long life.
– Keep the 18650 rechargeable battery in the cold and dark palace.
– Use it regularly, in the best case scenario – daily.
– Turn the battery off when it is not used.
– Avoid direct sunlight and high temperatures.
– Always carry the batteries in a case, or at least protected from direct contact with other stuff.
– Don’t mix and match batteries and chargers from different sets.
– Keep your device clean.

18650 Lithium Batteries Sometimes Explode

That’s true. Because of the chemicals included in a 18650 lithium battery, this little wonder produces a lot of power, but they also have the potential to blow.

Each cell contains lithium, sodium, potassium which are highly flammable elements. If you put them into the water, they would explode. So happens at a high temperature caused by an overheat.

Fortunately, manufacturers do a hard job today to minimize the danger of explosion, and most of the batteries have overcharge protection. It works in the following way: the sensor measures the amount of voltage pushed into the cell and then stops it from accepting any excessive power.

Some additional protection includes the fusing system built into the batter protecting from over-discharge. All this is implemented to protect the batteries from the so-called thermal runaway, so the risk of explosion in the new cells is minimal. If you want to level it to zero, then precautious maintenance is required.

Conclusion

The main thing that matters when choosing the best vape battery is the type of vaping you prefer. Either you want a more powerful hit and fast set-up, or your option is durability, you have to pick up your cell with the exact idea of how they will be exploited in the future. And also don’t forget about the maintenance rules for better and safe vaping.
