Size
In the case of the 18650 Battery, 18 represents a diameter of 18mm and 65 shows the length of 65mm; whereas 0 indicates that it is a kind of cylindrical battery. Similarly, in the case of 26650 battery, 26 represents the diameter of 26mm, 65 indicates 65mm length and 0 is again the indicator of cylindrical battery. Due to their larger size, these batteries are capable enough to deliver higher power, even if attached to a small flashlight. Therefore, the main selection parameter must be the diameter of the battery.
Capacity
The capacity of the 18650 lithium-ion rechargeable battery is somewhere around 1200mAh to 3600mAh. This capacity is usually supported by most of the vape box mods such as mech mods as well as regulated box mods. On the other side, the 26650 lithium-ion rechargeable batteries come with a large capacity in comparison to the 18650 Battery. Therefore, they can be used for VV vape box mods.
Voltage
The most powerful lithium-ion 18650 rechargeable batteries can take up to 4.4V maximum. Their charge current can be around 0.5 times the battery capacity. On the other side, the 26650 batteries are made up of Lithium Manganese Oxide material and they can achieve a nominal voltage of around 3.6 to 3.7 volt per cell. However, the suggested charging voltage can be up to 4.2 volts.
Which battery do you need to choose?
The selection of the best battery type usually depends upon the requirements and needs of an individual. It is important to mention that at present time, 18650 rechargeable batteries are more famous because they carry more power and can serve today’s high-tech flashlights.
However, the size, style, and capacity of these batteries usually vary from brand to brand. On the other side, the 26650 rechargeable batteries are high-performance, high-capacity batteries that can serve high-drain devices in a much better manner. It is better to read the guidelines and instructions provided by manufacturers for electronic devices first and then choose the relevant rechargeable battery to ensure trouble-free operation.
It is important to mention that rechargeable or lithium-ion batteries are one of the most popular choices these days. They are widely used in electronic devices, electric vehicles, and other portable unit.
