Juul Battery mAh

Juul Battery mAh, Voltage, Size & Wattage

This article provides a simple overview of the main battery features for Juul: mAh, voltage, size dimensions, wattage and more. The Juul battery print (inside the device) provides us with all the information we need to determine the strength and capacity of the power source.

Please refer to the table below for all specifications and details:

What Kind Of Battery Does A Juul Use?

Juul uses a regular lithium-ion polymer battery with an average size capacity of 200mAh and a voltage capacity of around 3.7 volts. To avoid danger, lithium-ion polymer batteries should be kept away from Juul pod leakage or other moisture. Always keep the battery at room temperature, away from relatively hot or cold conditions.

The Juul wattage is sitting at an approximate of 8.5 Watts, which is never reached because the battery is regulated. The rechargeable lithium-ion battery has an energy capacity of 0.74Wh, which is also printed on the battery itself. This metric stands for Watt-hours, which is an alternative measurement to the more well-known milli-amp hours (mAh).

How Do I Test A Juul Battery?

Testing a Juul battery is done by simply placing the magnetic Juul USB connector on the charging dock. Checking the current battery level is done by double-tapping your Juul device. The light indicator will show an approximate charge level (green for fully charged, yellow for medium charge and red for a low charge).

If you want to read out more specific details, you would need to use more sophisticated testing equipment. A battery analyzer could potentially read out all the relevant information that was provided in the overview table at the start of this article.

Since the pod systems do not have any type of digital display, it will be difficult to measure the exact power level percentages the batteries are at for any given moment in time. Juuls are not very sophisticated or expensive digital devices. This makes the need for such a detailed display unnecessary for the average vaping enthusiast.

How Long Should A Juul Battery Last?

Considering its power usage, a Juul battery is designed to last around 200 puffs or one full Juul pod. Over its entire lifespan, a lot of active users report the need for a Juul replacement after 9 months of regular use. With proper care and maintenance, the batteries could last you 2 to 3 years.

Recharging Juul batteries will take around 50 to 60 minutes each time. Over time, battery capacity will reduce gradually due to wear and tear. As explained in this article on extending the battery life, it is definitely possible to influence the lifespan of your power source.





How To Remove And Replace Your Juul Battery

If you wish to verify this information yourself, or if you have a reason to replace the batteries, you would need to follow a simple procedure:

  1. Remove any Juulpods from the device;
  2. Take a pair of (non-conductive) tweezers and push where the two contacts are;
  3. The bottom will pop out and you can gently remove the battery;
  4. Feel free to inspect, analyze and replace the contents at your own risk.

The instructions are explained in more detail (and more visually) in the YouTube video below. Please watch this video for more clarification on the proper removal of your power source:

Please note: Deconstruction of your device as shown in the video above will cause you to lose your manufacturers warranty. So please follow the procedure at your own risk.

When putting everything back together, you want to make sure that the indicator light and the oxygen sensor (a small circular object) are on the same side. That’s how you can make sure you fit everything back in there correctly. Don’t displace the rubber protector for the connector. When it becomes flush on the bottom, everything is connected properly.

Risk Of Juul Batteries Malfunctioning

There are some infamous tales going around in the vaping community about exploding Juul batteries. With proper use of only the official devices, this should not be considered a risk at all. Devices all have safety features in place to avoid any type of overheating or overcharging.

The smart-charge technology used inside the product is designed to minimize any type of potential risk. The official advice from the manufacturer is as follows: “To assure personal and property safety, charging JUUL should only occur at temperatures between 41°F and 113°F (5°C and 45°C).

In reality, most power sources are extremely well wrapped and protected against the elements. Most countries have safety regulations and standards in place to make sure consumers won’t be at any risk. Obviously, this all under the condition that ‘normal use’ is respected.

More Flexible Juul Alternatives

If you’re looking for a more powerful alternative to the popular Juul pod system, you have plenty of options to choose from. In another article on this blog, I compiled an overview of the best vape pod systems that could be Juul alternatives. Nearly all the suggestions are more powerful alternatives.

So if you’re looking for something with more strength or a better build, I can certainly recommend checking that article out. If you’re looking for other specific vape components or Juul accessories, feel free to check out this overview page.
