The biggest disadvantage of 18650 lithium batteries is that their volume is already fixed, making it difficult to locate them when installed in some laptops or products.
The capacity of a high-capacity 18650 lithium battery is generally between 1200mAh and 3600mAh, while the capacity of a typical battery is only about 800. If combined into an 18650 lithium battery pack, it can easily exceed 5000mAh.
Lithium ion batteries have a higher energy density, which means that they can store more electrical energy with the same volume or weight. For example, the energy density of a common 18650 lithium-ion battery can reach around 250Wh/kg,
The following are common specifications and technical parameters of cylindrical lithium-ion batteries:
Spot welding appearance: There is no explosion, virtual welding, or detachment phenomenon in the extreme ear, and there is no welding penetration, convex or concave points, deformation, explosion or other adverse phenomena at the bottom of the shell; Poor appearance and easy rusting; Welding through will cause leakage and the battery will be scrapped.
The so-called overdischarge refers to the situation where the battery discharges its internal stored power, and the voltage drops to a certain value before continuing to discharge,
18650 lithium batteries, a common type of battery in electronic products and power tools, actually have a rigorous production process. Let's uncover its mysterious veil together!
Capacity treatment at the factory of 18650 lithium battery manufacturers is an important step to ensure battery performance and safety, which helps to improve product quality and brand reputation to meet the needs of different customers.
