1. They have different rated capacities: the 26650 lithium battery has a capacity of 3000~5000mAh, while the 18650 lithium battery has a capacity of 2200~3200mAh.
2. The two batteries are different in size: the diameter of 26650 is 26mm, while the diameter of 18650 is 18mm.
3. The reference mass is different: the production quality of 26650 lithium battery is 94 grams, and the production quality of 18650 lithium battery is 45 grams.
4. The battery capacity is different; under the same lithium battery material, the 26650 battery capacity is larger than that of the 18650 rechargeable battery. If the 26650 rechargeable battery uses the same ternary material, it is generally 5200mAh, while the 18650 rechargeable battery uses 2600mAh.
5. The application scenarios are different; 18650 lithium batteries are used in rechargeable batteries for lighting equipment, lithium battery packs for industrial production supporting facilities, rechargeable batteries for pneumatic tools, rechargeable batteries for electric vehicles, power lithium battery packs, etc.; 26650 lithium batteries are used in energy storage technology communication base stations , solar power battery, etc.
6. Battery life is different 26650
