18650 batteries also known as vape batteries are lithium ion rechargeable batteries. These batteries get their name from their dimensions, which are 18mm in diameter 65mm in height. An 18650 battery has an average voltage of 3.7V and a maximum voltage of 4.2V. The capacity of 18650 batteries are usually within the range of 1,800mAh and 3,500 mAh. The largest capacity of any 18650 rechargeable battery to date is 3,500mAh, so be wary if you see one marketed with more than that as there are a lot of fake 18650 rechargeable batteries being sold online.
Yes, there are different types of 18650 batteries. To put it simply there are 2 types, you can get protected or unprotected cells. Protected cell 18650 batteries are usually preferred to and better recommended than unprotected 18650 batteries.
This is because protected 18650 batteries include a protection circuit that stops the cell from being overcharged, which is very important when it comes to the lifespan and efficiency of the cell.
No, in fact the name vape battery simply caught on as a nickname of the 18650 battery due to vaporizers, be it e-cigarettes or dry herb vaporizers being one of, if not the most popular uses for the 18650 cell; to the point where you may not even see the text ‘18650’ in a product title.
Our 18650 batteries are compatible with two of our dry herb vaporizers which you can see here.
The most obvious thing that you might be using 18650 batteries for is your vaporizer, whether that be a dry herb vaporizer, an e-cigarette, wax vaporizer or any kind really! These batteries can be used in all sorts of things, like flashlights, electric vehicles, vaporizers, cameras, power tools, laptops, and so much more! Believe it or not, Tesla builds their cars’ battery packs using 18650 rechargeable batteries.
If you are unsure whether you can use an 18650 rechargeable battery in your device, then check what size the batteries already inside your device are or look it up online and see what the specific batteries your device requires.
Yes, all 18650 batteries use lithium-ion as a key component of their electrochemistry meaning they’re made of cells in which lithium ions move from the positive electrode through an electrolyte to the negative electrode when being charged and back from the negative electrode to the positive electrode when being discharged. This is also known as secondary cell construction which essentially means that they can be recharged and used over and over again.
The runtime of a vape battery (or 18650 battery) will always vary depending on different voltages and amperages of the charger that is being used to charge the battery. Typically an 18650 battery should last anywhere from 1-4 hours, sometimes more, depending on those factors.
These 1-4 hours are of course only counting when the device that you’re using the battery inside is on, so if you only use your vaporizer shortly once a week or once every couple of weeks then the charge on your battery should last weeks if not months.
It should be noted though that leaving 18650 batteries in a charger for extended periods of time can be detrimental to the batteries. Leaving the batteries in a charger for prolonged amounts of time can cause a loss in capacity and charge cycles. The contrary can also be extremely harmful to the cell, so if you want your battery to perform for as long as it should then try to never allow your 18650 rechargeable batteries to fully discharge.
The lifecycle of an 18650 battery can be a very long time if used and looked after correctly. 18650 cells are fantastic because they can be recharged anywhere from 300 times to as many as 2000 times.
However, it is important to note that recharge cycles vary and are also limited. Each time a battery gets recharged, it degrades the tiniest bit. As the battery is recharged, the 18650 battery will degrade due to electro-chemical degradation and oxidation. Most good quality 18650 batteries will lose around 15% of their capacity every 500 discharges.
This degradation happens to all and any rechargeable battery, like 18650, 21700, 26650, 14500, AA, AAA or even a car battery. All batteries can only be recharged a limited number of times.
If you are worried that your 18650 battery might be on its way out then check for these 6 signs that your battery is dying:
If your 18650 rechargeable battery shows any of the signs above then it is probably time for you to get a new one to replace it.
Believe it or not, it’s in the name! 18650 batteries are 18mm (diameter) by 65mm (height).
18650 rechargeable batteries are widely available, you can of course purchase them from us here at Nectar, which we recommend as our batteries are of the highest quality, ensuring a long lifecycle and long sessions with your vaporizer. In fact we’re so confident in our 18650 batteries, we give a 2 year warranty with each of them.
However, if you need them right away then you should be able to find them in vape shops, technology shops and some high street shops.
In order to safely and efficiently charge your 18650 batteries, you will need a vape battery charger also known as an 18650 battery charger. We recommend our Nectar Dual 18650 battery charger for recharging your 18650 rechargeable batteries for a few reasons.
First of all, it has the ability of charging and discharging your batteries, meaning it doubles up as a power bank. It is of the highest quality, ensuring that you can safely charge your batteries without harming them in any way, and keeping them lasting long and efficiently. It also features an LED screen which shows you the power level (0-100%).
If you’re a battery fanatic, then you can also purchase multi-purpose battery chargers which are capable of charging a range of rechargeable batteries, not just vape batteries or 18650s!
Discharging, as the word suggests, is the opposite of charging. When you charge an electric component, such as a vape battery, you are storing potential electric energy in it.
However, when you discharge that battery, you are reversing the charging process and using the potential electric energy to drive other electronic components, like your vaporizer. Most of the time you’re using a battery, you’re discharging it.
If you want to discharge your 18650 batteries for whatever reason, then one of the best ways to safely discharge them is to use a heavy load on them. For example you could use the battery to operate an LED light. That way you can safely discharge the 18650 batteries.
There are a few different ways that you can test an 18650 battery if you would like to, however, this is not always necessary as you can look out for the signs that your battery is dying if you think it needs replacing. However, if you want to test your 18650 batteries then you can do any of the following:
No, 18650 batteries are not the same as AAA. First of all, AAA and 18650 batteries are different sizes – AAA batteries are 10.5mm by 44.5mm, whereas 18650 batteries are 18mm by 65mm. The only thing the 2 have in common is that they are both cylindrical batteries.
The amount of time it takes to fully charge an 18650 battery can vary depending on the charger that you are using, however, it will usually take up to 4 hours to fully charge your 18650 battery.
You shouldn’t store 18650 batteries for long periods of time, either charged or uncharged as the batteries can start to degrade. However, if you are going to store your 18650 batteries then we recommend that you store them at a low temperature, but not below 0°C. You should also store them at 40-50% capacity. The optimal storage conditions would be anywhere between 5°C to 10°C.
The highest capacity for an 18650 rechargeable battery is 3500mAh, however, the most commonly used 18650 batteries on the market have capacities between the range of 2000mAh, to 2600mAh.
Luckily for you we stock 3500mAh batteries here at Nectar, providing you with high capacities available in both individual and multiple packs.
18650 rechargeable batteries may have a voltage range between 2.5 volts and 4.2 volts, or a charging voltage of 4.2 volts, but the nominal (average) voltage of a standard 18650 is 3.7 volts.
