18650 Batteries


If you’re using any type of vaping device whether it be for Cannabidiol aka CBD, Tetrahydrocannabinol aka THC, or just plain old nicotine, you need to know about batteries, specifically, the 18650 battery. It’s the most popular of them all on the market today.

Most of the vape devices on the market today, and we mean most of them use the same principle of heating a coil to the required temperature to transform the e-juice from liquid to vapor form. While the design of the individual devices may vary slightly, the main thing most of these have in common is the type of battery they use. This is the 18650 battery, and here we’ll look into the best 18650 batteries that we recommend you use for purposes of vaping til the cows come home.

In other words, which battery will last the longest?!?!

Basic 18650 Battery Knowledge

To get the most out of any battery, you need to know the basics about them. The battery should have a high capacity, a high current rating, to be able to output high voltage and to have a low operating temperature. The capacity is outlined in mAh – milliampere-hours. And we will not go into details about this, but you should know that in order for the battery to have a longer life, it should be rated with a higher mAh value and it will hold its charge longer before it needs to be recharged.

Keep in mind, there’s nothing worse than losing a charge because your battery sucks!

The high current rating means that the battery is able to output the rated (necessary) current without overheating. There is a compromise to be made when considering the current rating and capacity rating, as one can only select one of these in their favor. A high current battery has a lower capacity rating and vice versa.

The high voltage output is important when using an unregulated/mechanical vape device, and the battery should output a higher voltage to the heating coil and create more vapor. This is also important for the regulated devices where the device draws a steadier current and saves the battery life.

The low operating temperature is very important for a battery of any sort, and this also goes for the 18650 vaping batteries. The low operating temperature means that a battery will last longer. If any battery overheats, it can burst and damage the user and the device.

The composition of the electrochemical element in the battery can be different but the two most likely are the Lithium Ion (LiIon) and the Lithium Manganese (LiMn). While both of these are high-performance batteries, the preferred choice for a battery for a vaping device is the LiMn as it is safer to use.

Composition Of The 18650 Battery

The 18650 standard is the size of the battery – 18mm in diameter and 65mm in length. While most manufacturers have this kind of batteries in their product range, one should carefully consider the overall price of a cheap vs. an expensive battery. A cheaper battery may seem the better choice in the beginning, but considering how often one has to change them, they are the worst choice in the long run.

All batteries suffer from overheating. To avoid this, you should select a vaping device that has some kind of ventilation over the battery compartment. You should not put your palm on this part of the vaping device to promote air circulation and heat dissipation.

All the rechargeable batteries should ideally be recharged using an AC charger that plugs into a wall outlet. But most vape devices have internal recharging via an appropriate USB charger. The USB charging is slower and the battery is in closed confines. The wall charger is the better option as it charges the batteries faster and enables cooling of the batteries.

And just one more thing about batteries: always handle them with care. Be careful when you put the batteries in the device, as there is only one way in which they will operate correctly in the device.

Now, for a vaping device, it’s best to select a battery that has good capacity, high current rating and works at a lower temperature. Below you will find our best choices for the top five 18650 batteries to use for vaping purposes.

  1. Sony VTC5 2600mAh

This is the holy grail of batteries. It is rated at 2600mAh, 30Amp, and it has a voltage range of 3.6 to 4.2V and a temperature range of 20 to 75°C. This means that this is one of the best 18650 batteries to use in a vaping device. Considering the price of a single of these batteries, the famous green Sony battery must be a good choice.

  1. LG HE4 2500mAh

The HE4 is one of the best batteries LG makes. This one is yellow, has a rating of 35A output, low operating temperature and is rated at 2500mAm. It is very similar in performance with the Sony VTC5 battery, so it is another great choice for a 18650 battery for your vaping device.

  1. LG HE2 2500mAh

Another one of the LG batteries, the HE2 is a good performance battery. Not as highly regarded as the yellow HE4, the brown HE2 has the same 2500mAh power output, but a lower charge at 20 A. It is still a very safe bet to use this kind of battery in a vaping device.

  1. Samsung 25R 2500mAh

Another great battery, the Samsung 25R is rated at 2500mAh, and is rated at 20A, although it can boost up to 35A. This battery is colored teal and is considered a very high-quality battery that is safe to be used in a vaping device of any kind.

  1. AW IMR 2200mAh

A good quality battery, decent power rating and low working temperature, the IMR 2200mAh by AW is a proper battery to be used in a vaping device. It is rated at 20A power output and it is red in color – just to be on the bright side of things.

Conclusion: Your Batteries Matter When It Comes To Vaping

When selecting a battery for your vape device, be sure to check for the power rating of the device and match it with a compatible battery. Be sure to check the expiration date on the battery and never buy batteries that are swollen (as these are certain to cause problems) and don’t buy them from unreliable sources.

Also, when purchasing batteries for your vaping device (and for any other device), don’t simply go for the cheapest battery, but select a reliable brand, preferably Sony, Sanyo, Panasonic, LG, Samsung or another respectable brand, to avoid getting a rewrapped battery that is only an imitation of the real thing.

Just one final note: Even though the 18650 batteries can be recharged hundreds of times, there will be a time when you need to replace them. Be conscious when disposing of any and all used batteries and always dispose of them in a safe manner. They aren’t great for the environment if you know what I mean.
