These lithium-ion batteries are designed for use with vape mods and pod mods that use external batteries. Typically coming in 18650 or 21700 options, they are commonly used for more advanced and powerful vape devices.
1. You can have a second battery charged and ready - so when your device runs out of juice, you can quickly switch over to a new one.
2. If you have a problem with your battery, you can continue using your mod device. This is far more economical than replacing the whole device!
3. Many mods that use replaceable batteries have a larger capacity, meaning you can keep vaping for longer.
18650 and 21700 are both lithium-ion batteries, and the different numbers refer to their dimensions. The first and second numbers refer to the diameter and the second two numbers to the length. For example, the 18650 battery is 18mm in length and 65 mm in diameter. The 0 at the end refers to the fact it is a cylindrical device.
While the numbers 18650 and 21700 refer to size rather than capacity, in general a 21700 will have more capacity than an 18650. That means most 21700s will last longer than the equivalent 18650 batteries. However, when choosing a battery it’s important to look for the mAh, which is a measurement of the capacity. This is a more accurate measurement of battery life than the size.
A 21700 will usually have more capacity, so given the same usage it will last longer than an 18650. However, an 18650 will be slightly lighter in weight than a 21700. If maximum battery life is important to you, you will find a 21700 battery best, but if weight is the most important factor choose an 18650.
Modern vape devices are designed for safe charging, whether the battery is charged in a mod device or in an external battery charger. However, it is important only to buy authentic mod devices and batteries from reputable manufacturers and vendors.
Yes, turning off your vape battery will increase the speed at which it charges, reducing total waiting time.
The battery capacity measures how much energy the battery can hold. This is measured in mAh (milliamps per hour). The battery voltage or wattage can often be adjusted and measures the amount of energy that is discharged.
Yes, and in general it is better to use a wall plug than to plug your device into a laptop. However, it is important only to buy plugs from reputable manufacturers and vendors, and to use one that is suitable for the country you are in.
Vape devices use lithium-ion batteries. However, the exact size and capacity vary depending on the device used. Devices that use replaceable batteries typically use 18650 or 21700 battery types.
