26650 vs 18650 Batteries: Differences
The difference between a 26650 rechargeable battery and a 18650 Li-ion rechargeable battery will be discussed, relying on two major factors; Capacity and Size.
Capacity
This refers to the length of the battery’s life.
A 26650 rechargeable battery has a large capacity of about 5000 mAh (may vary between brands) which enables a long run time between charges. As a result of its high capacity, it can be utilized in variable vape (VV) box mods.
The capacity of a 18650 rechargeable battery, on the other hand, is between 1200mAh and 3600mAh. The capacity of this battery is supported by most vape box mods.
Size
When it comes to size, the main difference between a 26650 rechargeable battery and a 18650 Li-ion rechargeable battery is the diameter. A 26550 battery is 65 mm in length and 26 mm in diameter, while a 18650 battery is 65 mm in length and 18 mm in diameter.
Due to a larger diameter, the total size and weight of the 26650 battery are bigger, so it may not fit in some devices. Check the specifics of your particular product to find out.
Usage
A 26650 rechargeable battery and a 18650 Li-ion rechargeable battery can be used alone or with other batteries depending on the purpose of the device to be built or the device to be powered.
However, both batteries come highly recommended for vaping devices, flashlights, toys, and torches.
