What are the differences between 26650 lithium battery and 18650 lithium battery?

Comparison of 26650 lithium battery and 18650 lithium battery The so-called 18650 lithium battery and 26650 lithium battery represent the size of the lithium battery, for example, 18650, 18 represents the diameter of the battery, 650 represents the height of the battery, and the unit of length is millimeters. Regarding the discharge performance, it has nothing to do with the 18650. The battery life of 18650 lithium battery and 26650 lithium battery is definitely different, because these two models are named after size, 18650, which means straight 18MM, height 65MM, in this way, 26650 must be larger than 18650 volume ratio Larger, so there is a larger space filling material to achieve a larger capacity, the current capacity of 18650 has 2200, 2600, 3100MAH, etc., and the capacity of 26650 generally has 4000, 4200, 4500MAH, leading to longer battery life Longer. From the perspective of the size of the lithium battery, the 18650 lithium battery and the 26650 lithium battery are also completely different, but they can be modified with each other, but there is also a difference. The thick barrel is equipped with a thin battery. There is an adapter barrel that can add the 18650 battery. Thick, put it in a 26650 flashlight. ●Battery volume comparison The 26650 lithium battery is larger than the 18650 lithium battery. They have the same cell height but different cell diameters. The 26650 lithium battery cell diameter is 26mm, and the 18650 lithium battery cell diameter is 18mm. ●Battery capacity comparison The 26650 battery capacity under the same battery material is larger than the 18650 battery capacity. Assuming that the same ternary material 26650 battery is generally around 5200mAh, the 18650 battery capacity is mostly around 2600mAh.
