- Most searched keywords: Whether you are looking for How Long Do Vape Batteries Last? | The Fog Works – The Fog Works Online Vape Shop Updating Choosing the right vaporizer for your needs can be a little tricky with so many options on the market. There are a few general features you have to consider to make the best possible choice. Apart from parts such as coils, mods, and atomizers, one of the essential components of any vaporizer is the battery.Factors such as charging time and battery life have the most significant impact on your entire vaping experience. Most devices come with a 18650 battery, but is it any good, and how long do vape batteries last? Keep reading, and we’ll tell you everything you need to know about vape batteries and what you can do to make them last longer.How long do vape batteries last?Most vape batteries usually provide between 200 and 500 cycles. That means that you get between 200 and 500 full charges before the battery stops working. The final number depends on the device you are using and how often you use it.As time goes by, your batteries will deplete faster, and when you reach a point where a single charge can’t provide more than a few hours of vaping, it’s time to change your batteries as soon as possible. Most popular vapes use the 18650 battery.How long do vape 18650 batteries last?These batteries are the most popular choice for most vape manufacturers all over the world. They usually provide an average of 250 cycles, but they can keep working for up to 500 cycles but discharge lower voltage than they normally do. They have a voltage of 3.7v, and most batteries offer 1800 to 3500 mAh of power.In other words, the average work time of your 18650 batteries depends on your vape’s voltage and the frequency of use. New batteries provide between 10 and 13 hours of vaping, but they will lose some work time over time.How often should I replace my vape battery?There is no universal right time when you should replace your 18650 vape batteries. Everything depends on your vaping experience. If you realize that your vape batteries don’t provide the same experience as before or lose power too quickly, you might need to change them as soon as possible.Lithium-ion batteries tend to lose capacity over time, and the more you use them, the faster they need replacing. The best thing to do is to replace your vape batteries once or twice a year, even if you didn’t notice any changes. Make sure that you recycle your old batteries to help your environment.Do vape batteries wear out?Yes, just like any other battery, vape batteries also wear out over time. As we’ve already mentioned, most 18650 batteries provide between 200 and 500 full recharges, but they might lose capacity much sooner. For example, if you take very big puffs at high-temperature settings while vaping, you can expect your batteries to die sooner.However, batteries can wear out due to other factors such as improper use and damage. If your batteries show any scratches, dents, or the wrapping comes off, your batteries might lose capacity even faster and possibly lead to an explosion. That’s why you should replace visually damaged batteries immediately. It’s always better to be safe than sorry.How do you know when your vape battery is bad?It doesn’t take a lot of effort to figure out that your vape batteries are dying. Generally speaking, if you feel like your vaping experience is deteriorating and your vaporizer stops working sooner than before, the batteries are probably losing capacity. Here’s a list of symptoms that all point to a bad vape battery:
Your vape depletes much faster than usual. Even after you recharge it fully, it loses power after only a few hours of use.
You can feel the battery heating up as it’s charging or discharging.
You’re using the same vape battery for more than a year.
When you charge the batteries, they reach the maximum capacity faster than usual.
Recharging batteries takes much longer than it should.
Damaged batteries.
If you experience any of these issues, take your vape battery out and replace it right away. It’s always better to be safe than sorry.Is it bad to leave your vape charging overnight?You should know this one by now – never leave any batteries charging overnight and unattended. Even though most battery charges are very safe and have their security features, sometimes they supply more power than they should, which can make your batteries burst or even explode.If you leave your batteries charging too long, that will have a negative effect and weaken the batteries. Battery charges also have their runtime, so try to avoid using old chargers to prevent overloads and short circuits. The best thing to do is get a dedicated vape battery charger used only for that and nothing else.Should I turn my vape off when I’m not using it?While most e-cigs and high-quality vaporizers have a built-in safety shutdown mode that automatically turns the device off after 10 seconds, some don’t. Generally speaking, most vaporizers don’t use that much power when they are idle, but you should still turn them off after each use. Without turning it off, your batteries will lose capacity faster, so you’ll have to replace them more frequently.Is it bad to charge your vape with USB?Not necessarily, as most vapes are designed to handle USB charging from other devices such as computers, TVs, consoles, and car chargers. That’s because these devices offer only a certain voltage, limiting the current that makes it to the batteries.However, using a USB wall adapter to charge your vape is not the best idea. If you use a cheap phone charger or an affordable vape, the best thing to do is avoid direct charging. Why? Well, cheap devices don’t have the best protection, which could completely ruin your batteries. One more thing, never charge your vape using chargers with a fixed USB cable. Using the wrong charger can damage your battery output and lead to further complications down the road.Why does the battery die so fast?If your vape batteries are dying faster than usual, they are ready to be replaced. Vape batteries tend to lose capacity over time, especially if you charge them for too long and use your vape frequently. Here’s a quick overview of the most common factors that shorten the life of your vape batteries:
Overcharging
Damaged batteries
Cheap charger
Extended use
Damaged battery wrapping
Misuse
Leaking battery
The Bottom LineVape batteries are usually very safe and easy to use, but they often lose capacity over time, negatively impacting your entire vaping experience. Vape batteries are replaceable, and they usually last between 6 and 12 months, depending on how often you vape.If you stick to the tips we covered and make sure that you use the vaporizer correctly, your batteries should provide you with around 300 charges before they need replacing. Whenever you feel like the batteries are not working as they should, go ahead and replace them just in case.How Long Do Vape Batteries Last?,Blog,The Fog Works Online Vape Shop,www.thefogworks.co.uk - Table of Contents:

The Ultimate Guide to the 18650 Battery
We get a lot of questions about the difference between rechargeable batteries and common one-time use batteries like AA & AAA batteries. Between different brands, strengths and confusing names, it can be easy to get lost when trying to research different types of rechargeable batteries and how to best care for them. We put together a complete list of our most frequently asked questions about 18650 batteries to help you understand how to get the very most out of your Fenix light and battery life.
What is an 18650 Battery?
An 18650 battery is a lithium-ion battery. The name derives from the battery’s specific measurements: 18mm x 65mm. For scale, that’s larger than an AA battery. The 18650 battery has a voltage of 3.6v and has between 2600mAh and 3500mAh (mili-amp-hours). (Osborne, 2019) These batteries are used in flashlights, laptops, electronics and even some electric cars because of their reliability, long run-times, and ability to be recharged hundreds of times over. 18650 batteries are what would be considered a “high drain battery.” This means that the battery is designed to generate high output voltage and current to meet the power demands of the portable device in which it is being used. Hence why these powerful little batteries are utilized in more complex, power-hungry electronics that require a constant, high level of power for operation. It also has a high depth of discharge, meaning that the battery can be drained all the way down to 0% and still have the capacity to fully recharge the battery. However, this is not recommended practice, as overtime this will cause long term damage to the battery and affect its overall performance. Learn more about caring for and enhancing the life of your 18650 later in the article.
History of the 18650 Battery
The lithium-ion battery was first invented in the 1970’s by an Exxon researcher named Michael Stanley Whittingham. His pioneering work to create the first version of the lithium ion battery then set in motion decades more research to finetune the battery to be as efficient and safe as possible. Then in 1991, a team of researchers and scientists named John Goodenough, Rachid Yazami, and Akira Yoshino worked together to develop and bring to market the lithium ion cell. The very first lithium ion battery cells were mass produced and sold by Sony. (Neverman et al., 2020) Since then, tweaks and enhancements have been made to extend the output and lifespan of the battery. Each of these changes resulted in a more efficient battery and in turn, a higher demand for their use and applications in the market. Today, lithium-ion batteries dominate the battery industry and have become ubiquitous in many household products we use everyday. There’s a very good chance you own many products powered by 18650 batteries, whether you realize it or not. As of 2011, lithium-ion batteries account for 66% of all portable rechargeable battery sales. (Osborne, 2019)
How a 18650 Battery Works
There are two types of 18650 batteries: protected and unprotected. As a rule of thumb, we always recommend using protected 18650 batteries. 18650 protected batteries have an electric circuit embedded within its packaging. This circuit protects the battery from “over charges” and “over discharges.” Both are situations you want to avoid. When a battery over charges, it can overheat, burst or catch fire.
It doesn’t take much imagination to understand how this malfunction can cause some serious problems for both the user and the manufacturer of the batteries. In fact, In 2016, Samsung released its newest smartphone, the Galaxy Note 7. It didn’t take long for reports to begin coming that the phones were exploding while charging. There had been a flaw in the design of the phone’s lithium ion battery that caused it to short circuit and catch fire.
Two separate recalls were put in place by the The U.S. Consumer Product Safety Commission, covering 1.9 million phones in the United States. Globally, to date, 96 percent of the 3 million phones that were sold have been returned. The debacle cost Samsung a pretty penny and a damaged reputation because of the number of fires and injuries the phones caused. It should be noted that the batteries within these phones were not specifically 18650, they were a larger, different type of 3500mAh lithium ion battery.
But for how widely used these batteries are, it seems like it is one of those easily overlooked technologies that we take for granted. From the moment we wake up to the moment we go to bed, there’s a very good chance we used some kind of 18650 battery. We don’t really realize how much they really do for us throughout our daily lives. Perhaps it’s because lithium-ion batteries are rarely seen on their own, instead they’re always encased inside the object they are charging. Not a lot of people take the time to consider how their electric toothbrush works, let alone how the batteries powering the toothbrush work.
There is actually a lot going on inside the battery’s tiny, colorful packaging. While the battery is being charged, the positive electrode lithium-cobalt oxide gives up some of it’s lithium ions which travel through the electrolyte to the negatively charged graphite electrode on the opposite side of the battery. The ions remain there until the battery is in use, during which the lithium ions travel back to the positive electrode, producing energy and powering the battery as it does so. In both the charging and discharging instances, electrons are flowing in the opposite direction of the ions around the outer circuit of the battery. (Osborne, 2019) The flow of ions through the electrolyte and electrons through the outer circuit are an interconnected process. One does not and can not happen without the other. Thus, should the battery completely discharge and the ions stop moving through the electrolyte, the electrons can’t make their way through the outer circuit and power is lost.
In the same way, should you turn off the object your battery is powering, the electrons will stop flowing through the circuit and so too will the ions. In essence, the battery stops discharging at a high rate. It should be noted that the battery will still continue to discharge at a very slow rate, regardless of whether the appliance is connected. Hence why you should always check the power level of your batteries every month or two in appliances that get more infrequent use.
What makes lithium-ions different from more simplistic batteries is their electronic controllers. These can be found only in the aforementioned “protected” batteries. Electronic controllers are built-in systems that regulate how the battery charges and discharges. It’s meant to prevent any overcharging or overheating that can, in some cases like the Galaxy Note 7 incident, cause lithium-ion batteries to explode. Using an unprotected lithium-ion battery can be tricky business to the uninitiated battery user. They are designed much more simply, meaning there is less of a chance for something to malfunction and are a bit smaller than protected batteries so they can fit into tighter spaces. However, the lack of protection opens the door to higher risks of overheating and explosion. Using unprotected batteries will, in general, yield the same performance but require more vigilance when it comes to charging and discharging.
Average Cost of a 18650 Battery
The cost of a 18650 battery can range widely depending on the brand, package size and whether it is a protected or unprotected battery. For example, the Fenix 18650 battery can range in price from $9.95 to $22.95 (these batteries are cheaper than most other brands when factoring in discounts), depending on the particular battery variation you are interested in. These batteries have a USB charging port right on the side of the battery itself, making recharging simple. They are at a bit higher price point than others because they are built with safety as a top priority, boasting three sets of overheating protection to prevent short circuiting so you can get up to 500 charge cycles out of a single battery without cause to worry about explosion or over discharging. Some unprotected batteries on the market can be found at cheaper prices, but as with anything you buy online, it’s important to factor in more to your purchase decision than just the price.
Pro Tip: As a general rule, if it seems too good to be true, it probably is. We suggest always buying any kind of technology, especially potentially dangerous ones like lithium-ion batteries, from a trusted source or name brand manufacturer.
Buying improperly manufactured or poorly made chemically-based products can yield unpleasant results, causing injury and destroying the appliance you were meaning to power. Before purchasing batteries online, it might be a good idea to check reviews from past customers or online tech forums to make sure you’re making a safe choice that also fits your power needs.
Different Types & Uses of 18650 Batteries
There are as many brands of 18650 batteries as there are uses. 18650 batteries are some of the most versatile on the market. They can be used to power just about anything, from electric cars to digital cameras.
As stated before, it is important to do your research beforehand when it comes to purchasing such potentially dangerous, though extremely useful products. Electric cars, such as the Tesla Model X and Model S , is what is known as a BEV, aka: battery electric vehicle.
These cars are powered by a hoard of lithium ion cells all working together. The Model S is powered by a battery pack that contains over 7,104 18650 cells capable of storing up to 85 kWh of energy. Recently, Tesla engineers have redesigned a new battery pack for their electric cars to hold 516 cells in each module for a total of 8,256 cells capable of storing a little more than 100 kWh of energy. This makes it possible for these electric cars to have a max range of over 300 miles on a single charge. It is a marvel to see how far scientists and engineers have come to in such a relatively short time. Everyday new improvements and enhancements are pushing the bounds of what this technology can do, how we think about electricity, and what role it will play in our everyday lives in the future.
How to Charge 18650 Battery
Depending on the brand of 18650 battery, you might need to charge your batteries as they were designed. But, for the most part, you don’t really need a specific type of charger or special cord to recharge your batteries – as long as it’s rated safe to charge lithium ion batteries. If you use a charger that is not meant for lithium ion battery types, it could result in, at best, permanent damage to your batteries and at worst, they could explode. Some batteries, such as the Fenix 18650 battery detailed above, actually are charged directly using simply a USB cord.
To get the very most out of your battery’s life span, we suggest making sure that your batteries are never fully discharged or drop too low in power if you can help it. Totally discharging the battery makes the ion transfer process much harder when it comes time to recharge the battery, thus limiting the capacity of the battery as a whole. The same is true for overcharging your batteries. Intaking too much power at once can put stress on the cells and cause damage in the long run. Instead, experts suggest “partial” charges to extend the overall lifespan of your batteries. While this does mean you might have to charge your batteries more often, it will save you time and money in the long run by helping you get the very most out of your existing batteries, saving you from the need to buy more.
How Long Do 18650 Batteries Last?
Most 18650 batteries have a life cycle of around 300-500 charge cycles. For example, Fenix batteries are rated for 500 cycles. This means that the battery will be able to fully charge to at least 80% of its initial capacity. Once it reaches that threshold, the battery’s “life cycle” is considered over. Though you can still probably get plenty more charges out of the battery, it’s capacity will slowly diminish further with time.
Most of us have all experienced this first hand when buying a new smartphone. Time and use will slowly diminish the battery’s life capacity, even with careful charging considerations. Extreme hot or cold temperatures can affect your battery life, as well.
Pro Tip: Make sure to never charge your 18650 batteries in below freezing temperatures! This can cause significant degradation and damage. For example, don’t leave your batteries to charge in a freezing garage in the winter.
How Long Does It Take to Charge a 18650 Battery?
The average 18650 battery takes about 4 hours total to charge. Of course, this can vary a bit based on the health of your battery and the type of charger you are using. To check the health of your 18650 battery, try to take note of how long it takes the battery to charge up, whether it is accumulating more heat than usual while it charges, if it is not producing as much power as it once did, or holding a charge as well. These are all indicators that your battery is reaching its end of life.
18650 Battery Storage Best Practices
18650 batteries need to be stored in a dry, room temperature space. Avoid any situations that might subject your batteries to either extreme cold or heat. Between the range of -20 to +50°C (-4°F to + 122°F) is sufficient but the most optimal storage temperature is somewhere around 77°F or 25°C. If you are planning on storing your batteries over a long period of time, it is actually better to have them charged at around 50% rather than 100%. This will help extend the lifespan of your batteries over time. Make sure to remove the batteries from it’s application before long term storage. For example, if you use your rechargeable batteries in a flashlight, take them out to be stored separately.
Pro Tip: Never store batteries in a pocket or bag that also includes any metal items such as keys, pins, or coins. This might cause accidental discharge. (battery & Instructables, 2017)
How to Discard Batteries Safely
Once your 18650 battery has reached the end of its life span, it is important to dispose of them responsibly. Never simply through these batteries into the trash! Though lithium ion batteries do not contain as many of the dangerous chemicals as other batteries, they still are considered hazardous waste and can cause fires or leak harmful chemicals into the earth. Many electronic or home improvement stores will have battery drop off zones or hazardous waste collection bins where you can get rid of your dead batteries without potentially causing environmental damage. Stores or collection centers will then send these batteries to recycling centers where they can harvest the metals inside to be reused. This is the most environmentally-friendly and economical way to dispose of old, damaged, or leaking batteries.

How to Prolong the Life of an 18650 Battery
What is a cycle?
When an 18650 battery is charged and discharged, this is counted as one cycle.
18650 lithium-ion batteries are charged up to 4.2V and down to between 2V and 3V depending on the cell’s specification for cut-off voltage.
To be safe, never discharge lower than 3.0V unless you know your cell’s specification.
Discharging occurs anytime you use the battery for power. The electricity is drawn from your device, and the battery discharges current. You can also use battery testing equipment to discharge a battery.
To charge an 18650, you should use a special charger for lithium-ion cells.
How is cycle life calculated?
Cycle life is determined by the difference in capacity of your cell taken from its first-use rating to its present rating. For example, if your cell started at 3000mAh, but now only has 2900mAh. 2900 mAh is 96% of the original capacity.
When this percentage reaches 80%, we say the cycle life has ended (even though you may get a few thousand more cycles out of your battery).
So if we take a 3000mAh cell, when do we say its life has ended?
(80% of 3000 is 2400) so when the cell reaches a capacity of 2400 mAh we say its cycle life is over.
How many cycles does a typical 18650 battery have?
Most modern 18650 batteries have a typical cycle life of 300 – 500 (charge, discharge cycles). When in high-amp or high-drain situations, this can decrease substantially to 200 cycles. If you go over the maximum discharge current limit (A) you can decrease the cycle life all the way down to 50 cycles.
In optimal conditions, your cells may achieve more than 500 cycles.
Some chemistries are able to cycle thousands of times before reaching 80% of their capacity.
How Long Do Vape Batteries Last? | The Fog Works
Choosing the right vaporizer for your needs can be a little tricky with so many options on the market. There are a few general features you have to consider to make the best possible choice. Apart from parts such as coils, mods, and atomizers, one of the essential components of any vaporizer is the battery.
Factors such as charging time and battery life have the most significant impact on your entire vaping experience. Most devices come with a 18650 battery, but is it any good, and how long do vape batteries last? Keep reading, and we’ll tell you everything you need to know about vape batteries and what you can do to make them last longer.
How long do vape batteries last?
Most vape batteries usually provide between 200 and 500 cycles. That means that you get between 200 and 500 full charges before the battery stops working. The final number depends on the device you are using and how often you use it.
As time goes by, your batteries will deplete faster, and when you reach a point where a single charge can’t provide more than a few hours of vaping, it’s time to change your batteries as soon as possible. Most popular vapes use the 18650 battery.
How long do vape 18650 batteries last?
These batteries are the most popular choice for most vape manufacturers all over the world. They usually provide an average of 250 cycles, but they can keep working for up to 500 cycles but discharge lower voltage than they normally do. They have a voltage of 3.7v, and most batteries offer 1800 to 3500 mAh of power.
In other words, the average work time of your 18650 batteries depends on your vape’s voltage and the frequency of use. New batteries provide between 10 and 13 hours of vaping, but they will lose some work time over time.
How often should I replace my vape battery?
There is no universal right time when you should replace your 18650 vape batteries. Everything depends on your vaping experience. If you realize that your vape batteries don’t provide the same experience as before or lose power too quickly, you might need to change them as soon as possible.
Lithium-ion batteries tend to lose capacity over time, and the more you use them, the faster they need replacing. The best thing to do is to replace your vape batteries once or twice a year, even if you didn’t notice any changes. Make sure that you recycle your old batteries to help your environment.
Do vape batteries wear out?
Yes, just like any other battery, vape batteries also wear out over time. As we’ve already mentioned, most 18650 batteries provide between 200 and 500 full recharges, but they might lose capacity much sooner. For example, if you take very big puffs at high-temperature settings while vaping, you can expect your batteries to die sooner.
However, batteries can wear out due to other factors such as improper use and damage. If your batteries show any scratches, dents, or the wrapping comes off, your batteries might lose capacity even faster and possibly lead to an explosion. That’s why you should replace visually damaged batteries immediately. It’s always better to be safe than sorry.
How do you know when your vape battery is bad?
It doesn’t take a lot of effort to figure out that your vape batteries are dying. Generally speaking, if you feel like your vaping experience is deteriorating and your vaporizer stops working sooner than before, the batteries are probably losing capacity. Here’s a list of symptoms that all point to a bad vape battery:
Your vape depletes much faster than usual. Even after you recharge it fully, it loses power after only a few hours of use.
You can feel the battery heating up as it’s charging or discharging.
You’re using the same vape battery for more than a year.
When you charge the batteries, they reach the maximum capacity faster than usual.
Recharging batteries takes much longer than it should.
Damaged batteries.
If you experience any of these issues, take your vape battery out and replace it right away. It’s always better to be safe than sorry.
Is it bad to leave your vape charging overnight?
You should know this one by now – never leave any batteries charging overnight and unattended. Even though most battery charges are very safe and have their security features, sometimes they supply more power than they should, which can make your batteries burst or even explode.
If you leave your batteries charging too long, that will have a negative effect and weaken the batteries. Battery charges also have their runtime, so try to avoid using old chargers to prevent overloads and short circuits. The best thing to do is get a dedicated vape battery charger used only for that and nothing else.
Should I turn my vape off when I’m not using it?
While most e-cigs and high-quality vaporizers have a built-in safety shutdown mode that automatically turns the device off after 10 seconds, some don’t. Generally speaking, most vaporizers don’t use that much power when they are idle, but you should still turn them off after each use. Without turning it off, your batteries will lose capacity faster, so you’ll have to replace them more frequently.
Is it bad to charge your vape with USB?
Not necessarily, as most vapes are designed to handle USB charging from other devices such as computers, TVs, consoles, and car chargers. That’s because these devices offer only a certain voltage, limiting the current that makes it to the batteries.
However, using a USB wall adapter to charge your vape is not the best idea. If you use a cheap phone charger or an affordable vape, the best thing to do is avoid direct charging. Why? Well, cheap devices don’t have the best protection, which could completely ruin your batteries. One more thing, never charge your vape using chargers with a fixed USB cable. Using the wrong charger can damage your battery output and lead to further complications down the road.
Why does the battery die so fast?
If your vape batteries are dying faster than usual, they are ready to be replaced. Vape batteries tend to lose capacity over time, especially if you charge them for too long and use your vape frequently. Here’s a quick overview of the most common factors that shorten the life of your vape batteries:
Overcharging
Damaged batteries
Cheap charger
Extended use
Damaged battery wrapping
Misuse
Leaking battery
The Bottom Line
Vape batteries are usually very safe and easy to use, but they often lose capacity over time, negatively impacting your entire vaping experience. Vape batteries are replaceable, and they usually last between 6 and 12 months, depending on how often you vape.
If you stick to the tips we covered and make sure that you use the vaporizer correctly, your batteries should provide you with around 300 charges before they need replacing. Whenever you feel like the batteries are not working as they should, go ahead and replace them just in case.
