1. Difference:
6 cells and 9 cells represent the number of cells in the battery, which proportionally reflects the capacity of the 9 cell battery, which is 3/2 of it. Capacity of 6 cells. A laptop battery looks like a square object on the outside, but it is actually made up of several lithium batteries, which is why we call the lithium batteries inside "cells", while Laptop batteries are commonly called “battery packs.” Laptop battery cell numbers on the market generally include 3, 4, 6, 8, 9 and 12 cells.
2. Distinguish the nine-cell battery
1 There is a big difference in appearance since the design module must accommodate 9 batteries, the area of the 9-. the cellular battery is usually much larger;

2. The weight is the same as above, so the weight of 9 cores isheavier.
3. If you want to know how to calculate the battery cell count, you can check out the following example:
Usually it will be something like 10.8V, 4400mAh. on the battery label. Let's use this as an example to explain.
10.8V represents the battery voltage specification, which represents the number of cells in series inside the battery. If you look at the specifications of cell phone batteries (single cell), they usually say 3.6V or 3.7V, so 10.8V is three times 3.6V, so the number of series connections for this battery is three.
Battery voltage specifications are generally 10.8V (three strings) and 14.4V (four strings). The voltage specifications of each battery type are fixed. 4,400 mAh (milliamp-hour) indicates the battery capacity specification and represents the endurance of the batteryerie. Usually it is measured in mAh (milliamp hours). It represents the number of cells connected in parallel. Generally, the capacity of a single lithium battery is 2200, 2400,
2600 mAh (or even more). And this 4,400 mAh is double the 2,200 mAh, so the parallel number of this battery is two. This number of parallel connections is not fixed for batteries, and the number of parallel connections for the same battery model can be increased.
Formula: Number of cells = number of series * number of parallel
So this battery is: 3 (series) * 2 (parallel) = 6 cells
< p> p >Sometimes you will see that the same battery model in the market has a 6 cell version and a 9 cell version. Just increase the number of parallel connections by 1 and it becomes 9 cells. But note that the number of concatenations will not change.
