510 Battery Information

Safety, Longevity, Quality and Service.  Those are the 4 things you can expect in every one of O2VAPE’s 510 thread batteries.  We have been one of the longest standing innovators developing these battery designs, so we want to start by eliminating any of the common confusion around these convenient, universal batteries.  So… what does “510 thread” actually mean and which battery is right for you?

In order to choose the best vape pen battery for you, it is important to be aware of the different battery functions, features, specifications and designs that are available with 510 threads. We will guide you with everything you need to know about how 510 batteries work, important considerations in getting the best vaping experience, tips to properly use and get the most out of your 510 thread battery and the key differences that make O2VAPE 510 batteries the best vape pens available anywhere. 


A 510 thread battery is the main body of a vape pen that comes with a standardized style of screw-on connection that is compatible with the widest range of oil cartridges, wax atomizers, dab tips and accessories. “510” refers to the design of the female screw threads built into one end of the battery –  10 x 5mm threads – which is the most compatible type of connection for vape pens around the world. This thread design allows for a tight and long-lasting connection. Although often referred to as the “battery”, in reality most 510 batteries are actually fully functioning vape pens that simply require users to screw on a cartridge, atomizer or other accessory in order to begin vaping their preferred form of concentrate.  

510 thread vape batteries come in a variety of designs, power specs and features, from basic pen-shaped buttonless batteries to high-tech models with variable power levels and digital displays to offer a range of vaping solutions that are tailored to the different needs of a variety of users and experience levels. For the best vaping experience, it is important that you choose a 510 battery that is a good pairing for your style of usage and the type(s) of concentrates that you will be using with the vape pen.


510 thread vape pen batteries all utilize the same basic function to create vapor:  when activated, the battery transmits electrical power to a heating element that quickly raises the temperature to a point where the concentrate (e.g. oil or wax) can instantaneously be transformed from a liquid or solid into a vapor for a user to safely inhale.  

There are several different ways that a battery can be activated, although the two most common styles are “Auto-Draw/Buttonless” and “Button Activated”.  A buttonless 510 battery essentially has an auto-on and auto-off functionality that is only activated when a user inhales through the mouthpiece.  This is the simplest form of vape pen and the easiest to use, with no need to worry about the vaporizer accidentally turning on in your pocket or bag – just breathe in and it works.  Button Activated vape pen batteries function by, you guessed it, pressing a button as you inhale.  Often these types of 510 batteries will offer a safety feature to keep the power turned on or off, such as a sequence of button presses (e.g. press 5 times quickly in a row) or an additional switch or lock on the battery.  Button activated pens often allow more precise control of the vaping process than auto-draw designs.

Some 510 thread vape batteries are designed for one-time use and are not rechargeable, but many vape pen batteries are rechargeable through USB-style charging or a dedicated power supply and cable.  It is very important that the power specifications of the battery match those of the charger for both battery life and safety by avoiding issues such as overheating. Many 510 batteries also incorporate LED lights to signal when a battery is low on charge.


There are several advantages that make these an ideal choice for oil and wax vapers.  

Compatibility – 510 batteries use an industry standard type of connection that makes them the most compatible option for the widest range of cartridges, atomizers, dab tips and other accessories.  

Ease of Use – simply screw your oil cartridge, wax atomizer or dip tip onto your charged battery and it is ready to go.  This straightforward process is perfect for beginners and appreciated by connoisseurs alike. 510 vape pens are also easy to clean and require little to no maintenance.

Portable & Discreet – the compact nature of 510 battery designs make them the perfect vapes for traveling and on-the-go lifestyles since they are small and light enough to easily slip into a pocket without attracting unwanted attention.  Some 510 batteries are designed to fly even more under the radar by mimicking a standard car key fob design, look like a normal stylus pen or have as small of a footprint as possible.  Certain batteries are also designed with ‘flip’ functionality to give your cartridges extra protection when not in use to prevent damage and leaks, so you can just toss your vape pen in your bag and go with no worries.

Affordability – 510 thread batteries offer the best bang for your buck of any vape pen battery type, whether you’re looking for an entry-level buttonless pen or a high-tech vaporizer with variable voltage, extra large battery capacity or a digital display with puff counters.

Now that those high level questions are out of the way, let’s explore more about what makes O2VAPE’s batteries the best choice for most vapers, how to decide on the right one to provide years of enjoyment, how to get the most out of your 510 thread battery and what to do if you experience any issues.

Additional Battery Buying Tips

  • 510 threads are universal for oil vape cartridges, however it’s important to choose the correct voltage for your cartridge and the features that best suit your needs.
  • Choose a quality product or expect to replace frequently
  • Choose a concealable model if you are active, and intend to keep it in a pocket.
  • Choose a higher mah capacity if you will not be able to charge for more than a week.
  • Check user reviews
  • Don’t overpay for design, check features and specifications
  • Consider a dab and oil compatible unit if you like both
  • Some batteries may use a magnetic connection, these are normally just adapters that are added to the standard 510 threading.
  • 510 threads may be paired with an ego thread which is a larger male counterpart often referred to as a 710 thread.  This is less common with oil vapes and also may require an adapter. You may find them on wax and dab pens though.

Now that those high level questions are out of the way, let’s explore what makes O2VAPE’s batteries a great choice, how to decide on one to provide years of enjoyment, and what to do if you experience any operating issues.

Our 510 batteries allow you to get a nice easy pull and a perfect puff  with almost any 510 thread cartridge while taking advantage of innovative features that set our products apart.  At O2VAPE we offer a wide variety of vape pen batteries, produced under stringent safety & quality testing with lifetime warranties included.  Finding the right vape pen battery requires a bit of knowledge about battery specs and an understanding of your usage preferences.  Here are some of the common decisions that people run into when choosing a vape pen with us.

Button vs. Buttonless Features:

If you are looking for the world’s easiest to use vape pen, a Buttonless 510 Thread Battery is the answer.  No button clicking, no adjusting settings and no chance of overheating your battery – just screw on a cartridge and inhale.  This type of vape pen uses “auto-draw” functionality that activates the battery whenever you inhale through the mouthpiece.  When you stop inhaling, or have activated the battery for the maximum safe amount of time, it immediately turns off.  Simple!     

We offer a few versions of buttonless vape pens at O2VAPE.  Our lower voltage buttonless batteries are designed in the shape of a stylus pen. These vape pens work great with oils in most modern cartridges. However, depending on the specs of the battery, some of them don’t reach a hot enough temperature for use with a more high-end ceramic cell cartridge. If you are interested in getting a more powerful draw or using a ceramic cartridge, then we recommend our 3.7 Volt Buttonless Battery.  The added power will help to increase the amount of vapor per puff and they work great with ceramic cartridges.

Button activated 510 thread batteries give users a more precise level of control over their vaping experience.  One major advantage is that you can continue to draw on the vape pen while heating up the cartridge or allowing it to cool, which some vapers appreciate since it allows you to take longer draws and better control the temperature with this manual technique.  For some people, the choice is as simple as preferring the feel of using a button to activate the battery.  It is important to note that most variable voltage vape pens are button activated, if the ability to vape with a variety of concentrates and cartridge types is a feature you value.  The downside of button activated pens is that there exists a chance of accidentally activating the battery while in your pocket or bag, but most button activated 510 batteries now incorporate a sequence of button presses as an easy to use master On/Off toggle.

Voltages Explained

Don’t be put off by the electrical terminology and numbers used in vaporizer specs. They are actually pretty simple to understand and navigate when choosing a vape pen battery.  Essentially, the bigger the numbers, the more power that a 510 thread battery can use and store.

Voltage refers to the amount of electrical power that can flow from the battery through the heating element to increase the temperature. The voltage range for 510 batteries is usually between 2.2v all the way up to 4.8v. The reason for this range is that different cartridge designs and materials require different temperatures to offer the optimal vaping experience.

For example, some cartridges use ceramic materials, which are a less efficient heat conductor and therefore need higher power (voltage) to produce vapor effectively. Some 510 vape batteries have adjustable voltage settings to let you fine tune the power and temperature based on the specific type of cartridge and concentrates you are vaping.

A vape pen battery with a high voltage rating does not necessarily mean it is a higher quality battery, it is simply a measure of power and it is far more important to match the right voltage to your cartridge and concentrate type. If you are unsure what is the proper amount of voltage to use, it is better to start with a lower voltage and increase it gradually…or just ask us!

At O2VAPE we offer vape batteries that are 3.3 volts, 3.7 volts and then adjustable voltage with the widest range around, these are referred to as variable voltage.  Matching your voltage with the type of cartridge you are using is important.  It will help to improve function, quality and most of all, taste.  The best taste and best effect comes from using the lowest effective voltage for your cartridge to fire.  This creates a vapor that avoids burning and creates the most pure flavor profile.  For traditional glass cartridges we recommend vaporizing around 3.3-3.7 volts. For ceramic heating elements, you can still fire them at about 3.3-3.5 volts and that is going to give you a smoother draw and a great terp flavor, but we do recommend 3.5 volts or higher for more vapor production.  Once again, batteries like the Flip UltraVari-Vape, Vari-Vape XL and Vari-Vape 900, Nano or Decoy all have a variable voltage feature that will provide the widest range of options.

Capacity (mah)

Battery capacity is usually measured in milliamp hours (mAh) and is a way to measure how much power a battery can store and how long your vape is going to stay charged for. Larger battery capacity sizes translate into more puffs and longer times between recharges. The higher the mAh, the more storage capacity the battery has. The smallest 510 thread battery capacities start at around 280 mAh, while the longest lasting 510 vape pens may clock in at 900mAh or higher.  The trade off for longer lasting battery capacities is that they require a bigger battery and a larger overall vape pen size. Keep in mind that operating your battery at a higher voltage will drain its charge faster, so if you like to vape at a high temperature, you might consider a battery with a higher mAh specs like the Vari-Vape XL or the Vari-Vape 900.


It’s all about style!  Most 510 thread vape pens are designed as a version of the classic cylinder-shaped stylus battery, which we have in a style that will be both functional as well as a fashionable accessory.

O2VAPE offers 6 standard color choices:  Gray, Black, Steel, White, Rose Gold and Wood Grain.  Not all colors may be available on every 510 thread battery model and prices for different colors may vary. Some of these colors come in a rubberized “Rugged” texture and we offer easy custom branding and logo options for wholesale orders.

However, O2VAPE also offers many other innovative choices, including the world’s most advanced key fob vape pen, a micro-sized vape that packs a huge punch and sleek versatile vapes with built-in capabilities for oil cartridges, wax atomizers and dab tips.  We also have developed high-tech features such as variable voltage and digital displays to enhance and fine tune your vape pen for any scenario.

Another choice when selecting a 510 battery is whether to be one individually, or as part of a Vape Pen Kit that comes with everything you need including a refillable 510 thread cartridge, protective carry case, USB charger and car charging adapter.  

No matter what your priorities are for the perfect vape pen – concealability, compatibility, durability, power, style or price – we have a 510 battery that will exceed your expectations.  Every 510 battery we sell is backed up with the confidence and security of our Lifetime Warranty and rigorous quality & safety testing.

Other Features

Other features of our batteries include conceal-ability like with the Flip, tiny footprints like with the Nano and Decoy.  Our Decoy vape pen even has an available adapter to make it compatible with the popular style pod cartridges.  These functional features will help you to differentiate and find something unique that fits your needs perfectly.

Top Vape Pen Battery Tips:


As mentioned above, one of the biggest advantages of a 510 thread vape pen battery is how easy they are to use.  Simply make sure your battery is charged, then screw a 510 thread oil cartridge (the industry standard connection style) snugly into the female threads of the battery for a good connection, then either inhale or press the button while inhaling, depending on the design. That’s it.

Each 510 battery has similar operating instructions, however, model specific instructions are included with all of the batteries that we sell.  Read the instructions on or in your vape battery’s box for specifics or check the product page or FAQ’S.

Always keep in mind that the best vaping experience will come from using a battery with a voltage that is properly matched to the type of cartridge that you are using.


Similar to using an oil cartridge with a 510 thread battery, a wax atomizer screws into the connector threads in the battery.  Then you add the wax, shatter or other form of concentrate onto the atomizer.  Activate the battery and inhale. Enjoy.

Wax atomizers require more cleaning than oil cartridges so that residue does not stick to the heating elements, which could inhibit the vaporizing process and burn off less tasty vapors. If manually cleaning your wax pen is not your thing, we offer vape pens with self-cleaning functionality.


Charging Directions: How Long Does it take to Charge a 510 Battery?

When charging an O2VAPE vape pen battery, only use the recommended charging adapter and a normally powered USB port.  Never use a rapid charger, as these can and will damage your battery.  Simply plug your USB charger into a standard port and then screw your battery into the provided usb adapter until the light turns red (snug, not too tight).  After 2-3 hours your battery will be fully charged.


If you’re having a problem charging or using your 510 thread vape pen battery, it’s likely a very easy problem to fix. Watch our troubleshooting guide or read our post on how to fix a 510 thread battery to resolve up to 95% of problems and quickly get your battery working smoothly once again.

If you experience a situation where your vape pen battery cannot be charged or if it does not hit when the cartridge is tightened, then most likely the connection plate at the bottom of the 510 threads on the battery needs to be adjusted. The connection plate transmits the power necessary for both vaporizing the oil and charging the battery and sometimes it gets knocked slightly out of place from over-tightening or accidental impacts. The easiest way to check if this is your issue is to look on the bottom of the battery for a LED light that turns on as you puff. If this light comes on but the pen is not producing vapor, then the battery is still working and it is just not conducting power to the cartridge. Follow our guides linked above to learn how to use a paperclip to easily adjust the connection plate and get back to vaping ASAP.


Occasionally it may become necessary to clean the connection point between your 510 thread battery and the cartridge or atomizer.  The good news is that it’s easy to do and will help you get the best tasting vapor.  

The first step is to unscrew the cartridge and remove the mouthpiece. Then, using a Q-tip or cotton ball soaked in isopropyl alcohol, wipe down the mouthpiece, the threads of both the battery and cartridge, and the bottom metal plate beneath the threads on the battery. The goal is remove any residue left behind from the oil or wax. Clean your battery until there is no residue left and be gentle with the metal plate beneath the connection threads, as it is the most delicate part of the vape pen. If this plate (or the heating coil on some vape pen models) gets damaged, then the vaporizer may become inoperable.

After you finish cleaning, screw the cartridge back onto the battery and you are ready to enjoy those tasty vapors again.
