Best 510 Batteries

510 batteries are the most popular vape batteries, no matter the device. 510 refers to the 10 x 5mm threads in each battery or thread. The threads can attach to any atomizer or battery mod with the same threading, which is why they are so commonly used. 510 batteries are simple to use and often have only one button. They can also come with variable settings controlled by the power button or a dial on the bottom.

Best 20700 Batteries

The 20700 cells were introduced into the market as a substitute for the smaller 18650 batteries but in larger, more power-intensive consumer products like electronics or power tools. They were used in a smattering of devices in the late 2010s, but they were often placed in larger than regular mods or mechanical mods. Since they were so specific to mechanical mods and were not widely used in smaller box mods, 20700-only devices were eventually discontinued.

Choosing the Best Batteries

The above table is a good guide to how much batteries cost. But there are other factors to consider. Again, a lot depends on what kind of vaping you do. For example, the Mig Vapor Pro 50 works best with dry herb and concentrates atomizers. It has a high-power output of 50W, which is the appropriate level for that material.

That example also charges on its own, so it does not need an external charger. However, e-juice vapers usually want higher outputs, so they need higher-capacity cells to power their mods to those levels.
The chemistry of batteries, however, does not mean that a high-capacity cell delivers more energy; it can just last longer than other cells.

The Secret Behind Battery Specs

A 3000mAh battery can discharge 3 Amps in one hour before, or, if you do the math, around 54W, which is a typical figure for most stock coils in sub-ohm tanks. The most important specs to look for when choosing a vape battery are:

  • mAh (milliamps per hour)
  • Amp rating/continuous discharge rating

Vapers who vape at high wattages (above 100W) cannot expect long battery life with a single 18650, as the highest output of a typical 18650 is around 30A. That’s why many box mods are dual-18650 devices, prolong battery life and give vapers more room to experiment with current discharge.

How To Charge or Recharge

All vape batteries are rechargeable. That goes without saying. The vape cells that are not rechargeable are those found in disposable vapes, which carry a charge that only lasts for around 200-300 puffs. In addition, some batteries are not rechargeable, like store-bought alkaline ones, but those are never used in vaping devices.

The Most FAQ About Batteries

How Long Does a Vape Battery Last?

The typical 18650 cells with a capacity between 2500 or 3000mAh can last for a long time if a high-wattage device does not drain it. If it is a dual-18650 device, that power source can last one or two full days, only if the discharge rate is less than the maximum allowed by the battery.
Conversely, using a single-18650 at high-wattage outputs will drain the cell quickly. Regarding the entire life of the unit, 18650 cells usually have charge cycles between 500-1000 charges.
Although different batteries have different lifespans, one way to prolong the life of any battery is not to let them fully drain. If you always drain a cell to the lowest possible voltage, it will tax the cell’s charging rate and deplete its capacity sooner rather than later.

When Do I Throw Away My Battery?

When the cell no longer charges, that means it is depleted. Old cells should always be disposed of properly. Batteries are filled with dangerous chemicals and should not be thrown away like regular garbage. If your battery has reached the end of its cycle after a certain period, the only way to throw it away is through a battery disposable or a battery exchange service.

What Went Into Choosing These Cells?

The most trust-worthy brands to buy are either:

  • LG
  • Samsung
  • Sony

These companies make cells that other brands buy and then re-wrap with their proprietary label. Not all the cells listed here are from those companies, though. The criteria for choosing these included:

  • Reviewing their ratings (amps and mAh)
  • User experience
  • Independent testing
  • Consulting with experts (online and in-person)

The most reputable source for battery ratings is the Battery Mooch, which regularly provides ratings and reviews, and tests to see whether a battery’s wrap is true.

Where can I buy cells?

There are many reputable online vendors, as well as brick-and-mortar shops, that sell vape accessories. Users can also shop on retail vape websites to find authentic, non-re-wrapped cells that have real ratings and are not fakes.

How do I charge batteries?

Use an appropriate charger like the Efest LUC V4, or any similar type of charger to recharge your lithium-ion cells.

It is essential to get a charger with safety features as well, so the power units do not overcharge or discharge. Getting a charger with several bays is also essential so that you can charge several at once.

How do I re-wrap batteries?

Wraps protect the battery and users from each other. A torn or damaged wrapping can expose the internal parts of a cell, which can be short if they come in contact with something metallic.

Re-wrapping a battery is a prevalent practice. Vapers wrap them in various colors and personalize them to reflect their tastes.
To re-wrap a damaged wrap, you will need the following:

  • PVC sheets or pre-rolled tubes
  • Ceramic-tipped tweezers
  • A hairdryer, heat lamp, heat gun or some other heat source
  • Insulators

Use the tweezers to remove the damaged wrap first. After it is off, take a pre-rolled tube (or a measured-out sheet) and place it around the cell. Use the heat source and wave it around – not too close or too long because it can melt – until it is securely fastened to the body. If you have insulators – they are recommended as an extra layer of security – place them at either end BEFORE you apply heat.

How to Install Batteries in a SMOK Device?

SMOK and all dual-18650 box mods use two battery installation methods:

  • Bottom loading
  • Backloading

Depending on the device, a mod will have a hinged bottom door, which users can open, or a side panel or removable section that protects the battery bay and needs to be removed to install the devices.

How Do I Dispose of Vape Batteries?

There are many ways to dispose of a depleted cell. Users can either:

  • Find a retail electronics store that recycles old cells
  • Check with your local waste collection program to see if they accept old batteries
  • Find a waste management company that specializes in cell disposal

How Much are a Dab Pen Battery and Charger?

Dab pens and chargers are very popular and widespread, so they do not cost much. A typical 510-threaded battery with variable voltage controls and a charger can cost anywhere from $10 and up. Some specialty devices have larger battery capacities and other features, which can increase the price but not much.

How to Fix a Dab Pen Battery That Won't Charge?

A dab pen battery that won’t charge often has connectivity problems with either the atomizer or the charger. You can try removing the plate from the 510 cells or unscrewing it entirely from the atomizer to check the connection. You can clean it and make sure the device makes the connection or leave the plate off so the battery can connect directly to the device.

Vape Batteries: The First Step to Safe Vaping

Was our information useful? Did you know a lot about batteries? Is there anything else that you’d like to know? Let us know in the comments section below.

There is no vaping without batteries. They provide the necessary electrical current to heat coils and vaporize e-liquid. With that said, there is more to them than that basic fact. Users should be aware of how a battery reacts to individual circumstances and always be mindful that they have limits. They can only do so much, and vapers need to know and respect those limits if they want to keep vaping and stay safe.
