The capacity of lithium-ion batteries can be reduced by as much as 25% at high current (C rating) and operating temperature as compared to their published capacity. Manufacturers typically publish the the capacity when the load is C/5 or one fifth of the rated capacity.
To calculate the capacity of a lithium-ion battery pack, follow these steps: Determine the Capacity of Individual Cells: Each 18650 cell has a specific capacity, usually between 2,500mAh (2.5Ah) and 3,500mAh (3.5Ah). Identify the Parallel Configuration: Count the number of cells connected in parallel.
The capacity reduction of lithium battery packs, in addition to the aging and decline of the battery itself, is more common. , The more important factor is the different self-discharge rate, resulting in unbalanced battery cells in series, which will eventually reduce the capacity of the lithium battery and become less durable.
Lithium-ion batteries, particularly the 18650 battery pack design, have become the industry standard for many applications due to their high energy density and long lifespan. Understanding how to calculate a lithium-ion battery pack's capacity and runtime is essential for ensuring optimal performance and efficiency in devices and systems.
Do not overuse the lithium battery or charge it when it is almost out of power. This is detrimental to the life of the lithium battery. The nature of the attenuation that affects the decrease in the capacity of lithium batteries is the decrease in the content of lithium ions that can be extracted.
If you look at your electronics, you'll notice that the lithium-ion batteries they come with lose capacity over time. Once the theoretical cycle number is exceeded, the capacity of the battery will have a very significant decline, and this time it is time to replace the battery.
