Batteries are most commonly grouped in relation to their size, the first two digits correlate to the width and the proceeding three, to height (these are all recorded in millimetres). Different not just in size, 18650, 20700 and 21700 vape batteries will also have different abilities when it comes to power output, capacity and current.

When choosing a vape battery for your mod, it's important to pick one which best suits your vaping needs. Batteries with higher Milliamp Hours (battery life) tend to have a lower discharge rate (lower Amperage, or how much power they can deliver at once). This makes them more suitable for lower wattage devices.Mar 13, 2018

What size battery do I need for my vape?

The standard batteries used for vaping are called “18650” batteries. This can be broken into two key parts: 18 and 65. The 18 tells you the diameter of the battery in mm, and the 65 tells you the length of the battery, 65 mm. So an 18650 battery is 18 mm in diameter and 65 mm tall.

Are vape batteries all the same size?

Some cells are taller because they contain a protection circuit. This protection circuit adds a few millimeters to the length of the cell, making it slightly taller than 65 mm. These cells are 18650 cells, so you would expect them to all be 65 mm tall. However, they clearly aren't all the same size (Figs.

Does it matter what battery I put in my vape?

All vapor devices utilize rechargeable lithium-ion batteries (with the rare exception of disposable pre-filled cigalikes), though each device has its own specific battery needs.

Will any 18650 battery work in a vape?

Can I use a 3.7 V battery instead of 3.6 V?

There is NO difference between 3.6 and 3.7 volt cells. It is simply a NOMINAL voltage, because every cell needs a reference point. In fact, either 3.6 or 3.7 volt cells have a fairly wide range. Fully charged, they are at 4.2 volts, and they can usually be discharged down to 2.75 or even 2.5 volts.

How do I choose a vape pen battery?

If you're wondering how to pick the best vape pen battery, opt for a battery that allows for low-temperature vaping, between three and four and a half volts. If low-temperature vaping isn't your thing, many vapor batteries will also allow you to increase your temperature.

What mAh is best for vaping?

If you have a single 18650 battery device, sometimes it's better to select a battery with a higher continuous amp output and less mAh. For example, the Molicell 2600mAh 18650 battery is better for high wattage vaping than the Extreme Vape 3000mAh 18650 battery.

Can you use any 510 battery with any cartridge?

Is it better to have A higher mAh?

Batteries with larger mAh ratings generally last longer than those with smaller ratings, assuming that the batteries are subjected to the same patterns of usage, but it may not mean a better battery. The milliampere hour represents a unit of electrical charge commonly used to measure battery capacity.

How do I choose A 18650 vape battery?

Remember, the slower the charge (typically 750mA), the longer the battery will last.

We've covered the best 18650 batteries for vaping in a separate post, be sure to check it out!

How long will A 3000mah vape battery last?

Even a small 300mAh battery should last you for a full day's worth of use, depending on how often you vape. As an example of how mAh works, a 3,000mAh battery gives you 3,000 milliamps for an hour or 1,000 milliamps for three hours.

What is single battery?

Single Battery Systems are incredibly portable and offer many benefits that cannot be said about integrated batteries, like the ability to change out the battery. Single Battery Systems tend to fire on the lower end of the wattage range as it is limited by the single battery and can generally last throughout the day when set to conservative vaping outputs. One drawback of single battery systems is that they cannot go higher than 90-100W, and the battery cells should be charged within a dedicated charger, like the Nitecore i2 Intellicharger. This forces the user to either bring around a charger or a spare charged battery. Spare batteries should be kept within a non-metallic carrying case. Check out our Guide on Battery Care & Maintenance to find out more. Single Battery Systems maintain a lightweight profile and low cost, but the weight and cost can easily add up if a charger or additional spare batteries are accounted for.

What are integrated batteries?

Integrated batteries offer a simplified user experience. Incorporating the battery into the chassis, this prevents the user from losing or switching out batteries when the device runs out. These benefits to portability allow the user to simply utilize a MicroUSB cable for recharges, eliminating the need to carry around spare batteries or a dedicated battery charger. The downside to integrated batteries used in starter kits is that eventually, through prolonged usage, the battery capacity and life begins to deteriorate, leaving the owner no choice but to upgrade or deal with the shortening lifespan of the integrated battery.

What is a dual battery mod?

Dual Batteries are generally found in box mod systems. Box mods tend to utilize more power with considerably higher output than pod systems. With many dual battery box mods easily surpassing 150W, the need for two batteries is clear in maintaining a sub-ohm system. Dual battery box mods tend to weigh more than integrated or single battery systems and cannot be optimally charged via MicroUSB port due to the higher capacity of the batteries. This forces the user to either carry an extra set of charged batteries and rely on dedicated battery charging paraphernalia. Batteries used in a dual setting should be “married” or used in the same capacity for their entire lifetimes. Users should ensure they are from the same brand with the same capacities and specifications. This allows the pair of batteries to be drained, recharged, and stressed in the same manner to prolong the lifespan of the battery.

Do starter kits come with batteries?

One would think that starter kits can function out of the box. However, many starter kits do not come with batteries, an essential item for vaping, and can be misleading to the uninitiated or newcomers. Unless your vape utilizes an integrated battery, many starter kits and pod systems that require external batteries simply do not include them for a variety of reasons. Batteries must be purchased separately and may need to be purchased as a single, pair, or trio, depending on the type and style of mod or pod system they will be used in.

Understanding the types of vape pen batteries

The primary purpose of a battery in a vaping module is to heat the oil from the cartridge provided to convert to smoke. The battery does not have to be too powerful for this function. Vape batteries can be internal or external. Each of them poses a few pros and cons.

Vape battery – Decoding the different sizes

External vape batteries are available in different sizes. Among these, the most popular codes are 18350, 26650, and 18650. New designs also have batteries of codes 21700 and 20700. The first two digits of the code refer to the dimension of the battery measured across, and the last three indicate the length in mm.

510 Threaded Batteries

The 510 threaded batteries are the most commonly used style for vape pens in the market today. Except for pods or other larger batteries, most portable vape pens use the 510 threaded battery setups. Although the 510 threaded battery style is typical for most cartridge types, some cells can be too powerful for a specific cartridge setup.

Choosing the right ratings

As discussed, a critical characteristic to determine the right battery for your mod is to evaluate the current and capacity ratings of your battery. Two features indicate how effective your battery is for vaping. The total capacity of your battery is available in the mAh rating, whereas the Amps rating gives the discharge rate.

Tips to enhance your battery life

Now that we have discussed quite some information about vape batteries, we will continue to explore ways to utilize them well. Using and maintaining your battery well ensures you can use your vaporizers or vape pens for a prolonged duration without any worry. The typical battery cycle for any rechargeable battery is 500 charges.

What is MTL vape?

MTL (Mouth To Lung) vape devices, on the other hand, produce less vapour and generally work at lower wattages. This is to support a mouth to lung vaping style, wherein the user inhales vapour first into their mouth and then carries it into the lungs, before exhaling. This inhale action is much similar to the draw of a cigarette. As a lower power output is experienced, these types of kits will largely work best with a lower Amp output battery, which in turn will offer you a longer battery life.

What is the best vape cartridge for low voltage?

There are essentially four generations of oil vape cartridges. The first being the classic polycarbonate or plastic vape cartridge , this generally works best on a low voltage battery. The second generation is a glass vape cartridge which utilizes a similar design with a glass casing and a higher quality design.

What voltage do you need for a pen?

Vape pen batteries come in a range of voltages and also in variable voltage styles. The common range that you will expect to find is between 3.3v and 4.8v. In general you should expect that any stylus or slim pen voltage will be in the range of 3.3v, they may adjust the voltage with the strength of the draw which may allow them to draw as low as 3.0v. This is about the right voltage for the common polycarbonate style oil cartridge but it won’t have enough power to properly heat a ceramic or wickless ceramic cartridge. These offer a higher quality vapor and require voltages in the range of 3.7 or higher. Finding the right voltage will depend on the resistance from the atomizer to reach the optimal temperature which is from 280* to 350* for most oils. Lower voltage means more pure vapor but a lighter hit, so always start low and work your way up. Voltage numbers don’t tell you whether it’s a better product, they just tell you whether it is the right product for your cartridge and vice versa.
