A Brief Introduction of Vape Pen Batteries and What They Do

To understand the purpose of the vape battery pen, you need to imagine the rest of the vaporizer. Think of two parts. The first part is the battery, and the second part is the cartridge. The cartridge holds your vape oils or dry bud. It also contains a heating element. When you pull a puff, you don’t want to pull liquid. Rather, instead, you want to pull vapor steam off a warmed surface. The heating element ensures that the contents are heated enough to evaporate but not enough to boil and burn.

The battery is the workhorse of the vape pen. It powers the heating element and keeps your experience consistent and pleasant. The most common battery used is the 510-thread battery. The “510” refers to the screw connection between the cartridge and the battery housing.

You aren’t going to physically connect a naked battery to a cartridge. Instead, the battery’s housing connects to the cartridge via the 510 screw threads. These 510-thread batteries are almost universal, but you still need to ensure that you match the correct battery with the right cartridge.

When looking for vape batteries for sale, don’t buy a battery just because someone considers it the best vaporizer battery. It still must function properly with your cartridge and cartridge contents. Further, you need to consider the size of your cartridge and the number of puffs you want per charge. Finally, the vaporizer battery life determines the longevity of your experience.

The vape battery pen powers the heating element, but the heating element could be vaporizing different compounds based on your preferences. So, the battery you choose could have a fixed voltage or a variable voltage. Certain compounds vaporize at differing temperatures. Increasing or decreasing the battery’s voltage allows you to alter the experience based on your usage.

Guide to Buying a Vape Pen Battery – A Comprehensive Look at All Factors that Make a Good Battery

Before determining what makes the best vape pen battery or even e-cig battery, you should understand how batteries function. Batteries are sold based on their engineering specs, and an informed consumer or brand marketer is a savvy buyer.

If you’ve ever searched for “vape pen battery review” or “best e-cigarette battery 2022,” you will see the ratings are based on three critical electrical concepts, mAh, amps, and voltage. The vast majority of these batteries are lithium-ion batteries.

What is a Lithium-Ion Battery?

Lithium-Ion batteries are currently the most efficient batteries on the market. As a result, they are synonymous with rechargeable electronics. Like an AA battery, they have a positive and a negative connection that allows electricity to pass through the circuit.

Unlike many solar batteries or car batteries, there is no maintenance necessary, and the battery doesn’t need ventilation like most acid solution-based batteries. In addition, due to the chemistry of the internal material, these batteries are rechargeable and hold the largest voltage for their size.

So, if you are buying a vape pen battery that isn’t a lithium-ion battery, you should be reconsidering your choices.

What is the difference between mAh, amps, and voltage?

Think of the water pipes in your house. When you turn on a faucet, water comes out. Your water pressure is the voltage of a battery. Voltage represents the amount of electrical pressure that a battery can exert. Higher voltage batteries are needed to kick-start large electronics like cars or heaters.

Your water rate, how much water pours out of the faucet, is the amps of an electrical system. How many electrons flow through the vape pen at any given time? This current is usually a measure of the flow of electrons across a point in each second.

Your water rate per hour, how much water you can get, is the mAh. The units are milli-amps per hour. It’s related to the amps but gives a rating of how powerful a battery is. The mAh tells you, on average, what current to expect from this battery over an entire hour. The larger the number, the more power is delivered to your cartridge consistently over time.

How does a Vape Pen Battery Work?

Putting everything together, you need to consider the needs of your cartridge and the battery’s specs. The battery pumps (via voltage) electricity (the amps) across the heating element in your cartridge (often expressed in ohms). Each cartridge will have a rated voltage required for proper use. Too much voltage and you can burn out the heating element. Too little voltage and your heating element won’t work. So, remember voltage matters.

Choosing the Right Battery for Your Vaporizer Pen Needs & Budget

Fortunately or unfortunately, the vaping industry has developed multiple vape pen battery options based on your needs, budget, and preferences. So what’s the best vape pen battery on the market? Lithium-Ion batteries are the best and most efficient vape pen batteries.

Here is a quick breakdown of all the key considerations you will need to consider before making a purchase. Remember, when you buy vape pen batteries online, make sure the seller is reputable and provides authentic merch.

What are the best vapes batteries and optional benefits?

Button vs. Buttonless Batteries

Do you want to turn the unit on and off? You have a choice. However, there are pros and cons to each. The buttonless or auto-draw batteries are the most user-friendly batteries on the market. There is no need to push anything. You only need to breathe from the mouthpiece. However, this means that the battery stays “on” constantly. The charge will last for a few days before it needs to be recharged.

The button-activated batteries hold a charge longer because you control when the battery discharges electricity to the cartridge. Further, if you are looking for a variable voltage battery, you will need to buy a button-activated unit.

Voltage Matters

Make sure that you choose your cartridge first. Each cartridge will come with a voltage rating. This is directly a result of the vaporization temperature of the product you are vaping. Make sure to match up the right voltage battery with the correct cartridge.

Capacity Choices

The battery’s capacity (how big the energy bucket is) determines how many hours of puffing you have and is measured in mAh. The smallest vape pen batteries have a capacity of around 280 mAh. The largest batteries can hold upwards of 900+ mAh. Depending on the size, style, and charging availability, the choice is yours.


Aesthetics always matter. Don’t listen to anyone that tells you otherwise. What are your needs? Does physical size matter? Many consumers look for slim designs that allow for discreet usage and storage. Or do you care more about capacity and hate the idea of charging the battery every few days? What’s your favorite color? Do you want it to match the cartridge? Do you need something rugged for travel or something more elegant for home use?

Other Considerations

  • Some cartridge brands sell their batteries for ease.
  • Certain batteries have added features to make the experience more enjoyable.
  • Don’t overpay for features. Get what you need and nothing more.
  • Check out the reviews of the batteries before you buy.
  • 510 threads need an adaptor if used with 710 threads.

How to Care for Your Vaporizer Batteries Properly For Optimal Performance?

How do I charge my vape battery properly?

If you wonder how to charge a vaporizer battery properly, you aren’t alone. However, don’t worry. It’s easy. The first step is to read your manual. If you purchased the battery from a reputable brand, the battery should come with a manual explaining the unit’s inner workings. It will show you step-by-step the process to charge the battery.

Some batteries can be replaced. Others have a USB port allowing for easy charging via a USB charger. Others allow for external unit charging. It all depends on the kind you buy.

However, one thing to remember is that you shouldn’t charge your lithium-ion battery constantly. It is healthier for the unit if you wait to recharge when the power is drawn down to almost dead. Batteries have a lifespan that is partially based on the number of discharge-recharge cycles.

Are there any other considerations for caring for a vaporizer battery?

Keep your unit clean. If you drop it in the mud or dirt, make sure you clean all the surfaces, edges, and connection points. It is worth unscrewing the cartridge from the battery and cleaning out the threads. You can easily do this with a cotton swab. No need for water. Just use a little pressure to wipe away any collected grime and reconnect the parts.

Conclusion & Final Thoughts

It may seem that choosing a vape pen battery is overwhelming. However, most batteries offered do the same thing, power your cartridge. All you need to consider and focus on are your needs and wants. Get something you will want to use. Get something that makes you happy. The more enjoyable the unity, the more likely you will have a great vaping experience.
