In a perfect world, batteries would last forever. In reality, however, all batteries will eventually wear out, no matter what chemistry they are based on. Lithium ion batteries experience little-to-no wear when they are not being used, so the lifespan of a lithium ion cell is related to the number of charge and discharge cycles it experiences rather than to how old the cell is.
Generally speaking, the average vape battery cell is going to be good for anywhere between 300 to 500 complete cycles before it starts to show signs of degradation. This makes it so a vape battery will last somewhere between 6 and 12 months, depending on how much you vape and what type of mod you use.
In this article, we will explain how vape batteries age over time. We will also tell you some things you can do to drastically increase the life of your vape battery.

What Types Of Vape Batteries Are There?
While there are many different types and sizes of batteries that are used for vaping are general purpose cylindrical battery cells and vape-specific 510 batteries. 510 batteries come in all sizes, but 650mAh and 900mAh are the most common.
When it comes to cylindrical cells, some mods use 21700s and some mods use 18650s. Any mod that a 21700 will fit in can also support an 18650 if an adapter sleeve is used.
The most important aspect of choosing a cylindrical battery cell for vaping is to make sure the cell can handle the amount of current that your mod will pull from it.
|Battery Type||Capacity||Cycle Life||How Long It Lasts||Price|
|Low Quality 510||650mAh||300||2-3 Months||$10|
|High Quality 510||900mAh||600||6-8 Months||$20|
|18650 Vape Battery||2500mAh||500||1-2 Years||$5|
|21700 Vape Battery||4200mAh||700||1-3 Years||$7|
|Premium 21700 Vape Battery||5000mAh||1000||1-3 Years||$10|
How Long Does A Vape Battery Last Per Charge?
That depends on many factors, but in general, a 900mAh vape battery is good for about 800 puffs. For most people, this means a 900mAh vape battery will last 8-10 hours. In comparison, a 650mAh vape battery battery is only able to provide around 400 puffs, which equates to about 6 to 8 hours of use.
Cylindrical vape cells, in contrast, can have capacities ranging from 2000ma all the way up for 5000ma! So, as you would expect, a high quality cylindrical vape battery can last several days on a single charge.
How Long Do 510 Vape Batteries Last?
When it comes to vape batteries, you get what you pay for. Cheaper 510 batteries use smaller or lower quality lithium ion cells and cheaper cylindrical cells offer far lower capacities and current levels than their higher priced counterparts.
For example, this cheap vape battery won’t last long at all. These are no different from the $10 vape batteries you find in your local gas station. The difference is, the ones in the gas station conveniently available when you break or loose your normal vape.
The one on Amazon, however, are just as poor in quality but no where near as available. Those low cost 510 ecigg batteries in that particular formfactor are known to go bad after just a month or so of regular use. In the case of heavy use, you would be lucky if one of those batteries lasted you a week.
It’s best to only buy one of those if there are literally no other options. In the case of Amazon, however, there are plenty of options.
For example, this Silver Travel eCigg Battery Kit will provide a much higher performance and far more reliable experience. These silver batteries are known to last 6 months or more with moderate usage, and they even come with a coil.
How Can I Make My 510 Vape Battery Last Longer?
A vape battery, like all other lithium ion batteries, ages based on the number of charge and discharge cycles it experiences. So, in order to get the most out of your 510 vape battery, its important to fully cycle the battery as little as possible.
So, to make your 510 vape battery last longer, its important to never let it fully die. Instead, recharge your 510 vape battery when its about half way dead. This will prevent the battery from fully cycling and can increase the vape batteries lifespan by up to 30 percent.
How Long Do Cylindrical Vape Batteries Last?
In general, Cylindrical vape batteries last longer than 510 vape batteries. This is because whether its an 18mm wide 18650 cell or a 21mm wide 21700 cell, a cylindrical vape battery is a lot bigger than a 510 vape battery.
This larger size not only means that a cylindrical vape battery is going to have more capacity than a 510 vape battery, but it will experience far less current per unit of volume compared to a 510 vape battery.
This means that larger, cylindrical vape batteries produce less heat under a given load when compared to 510 vape batteries. For these reasons, its not uncommon for a cylindrical vape battery to last 6 months to a year.
WARNING: Fake and improperly listed lithium ion cells are common and widespread among all online marketplaces.
For example, check out this 5800mAh 18650 Battery 3.7V Button Top Long-Lasting Li-ion Battery. It claims to have a capacity of 5800mAh, but that is impossible. With the most advanced, most up-to-date, most power-dense lithium ion chemistries, the highest capacity that can physically fit in a cell is about 3600mAh.
So, if any manufacturer or supplier is claiming that an 18650 cell has a capacity higher than 3600mAh, then that is a huge, massive, red flag. Stay away from everything made by that company.
In contrast, take a look at this 2Pc 2500mAh 3.7V Samsung INR18650-25R 18650 Rechargeable Battery Set. As you can see, it’s a 2 pack of 18650 battery cells and each cell is claimed to have 2500mAh of capacity, which is a realistic figure.
In addition to having reasonable and physically possible specifications, the cells are made by Samsung which has been a trusted name in electronics for several decades at this point.
How Can I Make My Cylindrical Vape Battery Last Longer?
Quite a bit. Unlike 510 vape batteries, a cylindrical vape battery is a common, battery cell that can be charged with many different types of chargers. So, you could buy a charger that allows you to adjust the charge voltage of your vape battery.
By default, all battery chargers will charge a lithium ion cell to 4.2 volts. If you use a charger like this Universal Household Battery Charger, you can remove your vape battery from the charger when it reaches 4 volts instead of 4.2 volts. If you do this, you will loose 15 percent of your single-charge battery life but you will more than double the amount of times you can charge that cell.
When Should I Replace My Vape Battery?
Unlike regular maintenance on a vehicle that needs to happen after so many miles, there is no set schedule when it comes to replacing a vape battery.
If you are a heavy vaper and you leave your mod on a high power setting, you will more than likely have to replace your batteries every few months. If, on the other hand, you are a more casual vaper, your batteries could last for a year or even longer before needing to be replaced.
How Do You Know If Your Vape Battery Is Bad?
There are several scenarios that indicate that a vape battery may be failing. For example, if you are vaping at the same wattage but you notice the battery does not last as long as it used to, that is a strong indication that your vape battery is going bad.
Also, if you notice your vape battery getting hotter than it did before at a given wattage, that is a sign that the battery has developed a higher internal series resistance.
How To Test Vape Battery
With nothing more than a battery charger and a multimeter, you can determine if your vape battery needs to be replaced.
Step 1: Put your vape battery in a battery charger for 24 hours
Step 2: Remove the vape battery from the charger and let it sit for 24 hours
Step 3: Set your multimeter to 20VDC
Step 4: Connect the multimeter probes to each end of your vape battery
A standard lithium ion battery charger will charge a cell to 4.2V. A bad battery will either not be able to make it all the way to 4.2V, or will slowly lower from 4.2V because of internal self discharge.
Check your vape battery voltage. If it has dropped to 4.1 volts or less without being used, the vape battery needs to be replaced.
You may not have to do any of that. If you have one of the nicer vape mods that shows your batteries voltage on its screen, then you can just look at that. You need to replace your vape battery if you notice it cannot charge to the voltage that it used to.
Should I Turn My Vape Off When I’m Not Using It?
Yes. Leaving your vape on will not drain the battery to any appreciable degree, but leaving it on can be dangerous. If you leave your vape on and you put it in your pocket, purse, or handbag, you could accidently press the button.
If this happens it will destroy your coil and burn up all your e-liquid. In a worst-case scenario, it could start a fire.
What Batteries Are Safe For Vaping?
The most common battery cell used for vaping is the 18650 lithium ion battery cell.These cells are readily available and easy to find. It’s important to make sure you get an 18650 that can handle the amount of current that your vape mod requires.
For example, there are some vape mods that can pull 10, 20, or even 40 amps from a single battery cell. While this is safe if the cell installed in the mod can handle that amount of power, it could result in an explosion if the installed cell cannot deliver the required amount of current.
How Much Do Vape Batteries Cost?
When buying vape batteries at a vape store, they can be expensive. Common 18650 and 21700 cells are often sold for somewhere between $10 to $40 for a single battery cell. Remember, these same battery cells can be purchased from various online outlets for $3 to $6 per cell.
How Do You Marry A Vape Battery?
When battery cells are used together, it’s best for them to have the same voltages and similar wear level. The concept of marrying batteries together was developed as a way to keep cells balanced. This is achieved by making sure the cells experience the same amount of load.
The theory is that if cells are ‘married’ in this way, they will have better performance. This is not necessarily the case.
Can You Remarry Vape Batteries?
Yes. Because marrying batteries isn’t really a thing in the first place. The concept of marrying cells comes from a lack of understanding of how batteries work.
The concept of marrying battery cells together comes from the need to keep the cell voltages balanced. There is a theory in the vape community that states if you ever use two batteries separately, you cannot use them together again. This is completely incorrect.
Based on this flawed understanding, there is also the common belief that you cannot add a ‘married set’ to another battery to use in another mod. This is incorrect. There is also the myth that you cannot remove a battery from a married set and use it in another mod and then try to remarry it.
Yes, two battery cells used in different devices will age at different rates. The fact of the matter is that at the current levels required for vaping, this different is negligible.
So, keep in mind that nothing bad will happen if you mix and match your battery cells. While it is best to make keep cells at the same voltage, its not required.
No battery is perfect. No matter what type of battery it is, all batteries will eventually wear out.
On average, a vape battery lasts for somewhere between 6 months and 12 months, depending on how often you vape. The average vape battery has a cycle life of between 300 and 500 charge and discharge cycles. After about that many cycles, the battery will only hold about 80 percent of the energy it used to. After its rated cycle life, a vape battery will have a higher internal resistance and generate more heat .
After learning everything about vape batteries, you no longer have to ask yourself ‘How Long Do Vape Batteries Last?’ because now you know! Thanks for reading!
