The battery is a crucial component for artificial smoking. Its quality determines the battery life of an e-cigarette. The power source can be built-in or removable. It's best to buy devices with a removable battery.
Batteries for electronic cigarettes are produced by different companies, for example, LG, Sony, Samsung, Panasonicand others. Companies that supply rechargeable batteries include AWT, Efest, and others. It's best not to trust Ultrafire and TrustFire, as reviews from people indicate that they produce low-quality products.

- AW 18350 – 900 mAh. 10 A.
The electronic cigarette comes with a special USB charging cable and instructions.
Classification of batteries for electronic cigarettes
Let's find out what types of batteries there are for vapes by shape, electrolyte and other parameters.
Battery dimensions
XXYYY – the first two characters indicate the diameter in millimeters, and the last three are the height, measured in the same units. In other words, a popular format for vape is 18650 with a diameter of 18 mm and a height of 6.5 cm. The same disassembly can be done with batteries such as 20700, 14650, 21700, etc.
Electrolyte type
According to chemical composition, there are three types:
- Lithium ion.
- Lithium manganese or Li-Mn.
- Lithium polymer.
Lithium manganese are the safest. They can withstand long-term impacts and are the most resistant to physical influences. They exhibit significant activity in critical tests. Therefore, manufacturers decided that such e-cigarette batteries do not require protection. Li-Mn batteries withstand high-current charging very well. The main drawback of these batteries is their small capacityBut thanks to modern technology, it can reach up to 2500 mAh.
Lithium-ion are the most popular and have high capacityFor safety, they are equipped with special protection. These batteries are very sensitive to temperature fluctuations. Incorrect charging can quickly damage them. Therefore, they must be handled with extreme care.
Lithium polymer batteries They are the least safe. The slightest violation of battery handling rules can lead to an explosion. But despite this serious drawback, they have several advantages:
- They don't heat up much under load.
- There is a small sag under load.
- High output current values.
The use of such power sources requires great care.
Batteries equipped with an electronic board
If your e-cigarette battery is like this, you don't have to worry about high power. It's controlled by a circuit board. The most suitable power storage devices are:
- Samsung 18650/30Q – 3000 mAh, CDR – 19A.
- Sony 18650/VTC6 – 3000 mAh, 19A.
- LG 18650/HG2 – 3000 mAh, 20A.
Mechanical electronic cigarettes
When using these devices, pay more attention to current output. Also, keep capacity in mind. The following have proven themselves to be effective:
- LG 18650/HD2C – 2100 mAh, 25A.
- Sony 18650/VTC5a – 2500 mAh, 25A.
Universal
There are batteries that can be used in any model. They usually have average characteristics. Here are some models of such batteries:
- Elgie 18650/HE2 – 2500 mAh, CDR – 20A.
- Samsung 18650/25R – capacity 2500 mAh, 20A.
- LG 18650/HE4 – 2500 mAh, 20A.
What's happened CDR in batteries for electronic cigarettes?
Essentially, these three letters represent the maximum continuous discharge current. This indicator characterizes stable operation over a long period of time. Sometimes you'll see the abbreviation 20amps, which indicates that 20 amps equals the CDR in 1 second.
And if you see the marking 10 C, it means you need to resort to the formula (X/1000) * 10 to calculate the maximum continuous current. The letter X means capacityBattery. A 2500 mAh battery will have a CDR of (2500/1000) * 10 = 25A.
To calculate the optimal CDI value, divide the volts by the resistance. If the e-cigarette coil has a 0.15 ohm coil and the battery has an output voltage of 4.2 volts, 28 amps will be required. So, divide 4.2 ohms by 0.15 ohms to get this value.
We do not recommend using batteries with a current rating lower than the rated value, as this could damage the electronic device. And that would be the worst-case scenario.
Choosing a battery for your e-cigarette requires careful consideration. Your safety and future vaping pleasure depend on it. The information above will help you make the right choice.
