1. The lithium battery “cells” in today’s laptop batteries are typically around 3.6V per cell.
2. The arrangement of lithium batteries in the battery box: 8-cell lithium batteries are 2 in parallel and 4 strings, 6-cell lithium batteries are 2 in parallel and 3 strings Ni-Mh are 8 strings
3; . Commonly used batteries are 14.8V, 4400mAh, 14.4V, 3800mAh. The batteries are all 8 cells. You can estimate it and get it.
4. 14.4/3.6=4, so that’s 4 in parallel; 14.8/4=3.65, each section is approximately 3.65V.
What is the difference between 6 and 9 cell laptop batteries?
< p>1. Different quantities
A 3 cell lithium battery is made up of 3 small batteries, 6 cell is made up of 6 small batteries.
2. Different capacities
Generally speaking, the more cores there are, the greater the capacity of the banklithium battery is great.
3. Different battery lifespan
Under the same conditions, lithium batteries with more cores have a longer lifespan.
4. Different prices
Other conditions being the same, lithium batteries with more cores are more expensive.
Detailed information
The so-called core refers to the cylindrical lithium battery, the most common is the standard 18650 round lithium battery. Under normal circumstances, the markings of 3-cell lithium batteries and 6-cell lithium batteries on laptop batteries are: 11.1V === 2200mAh (3-cell lithium battery) , 11.1V === 6600mAh (6-cell lithium battery). .
The battery life of a 3-cell laptop is 2-3 hours, that of a 6-cell laptop is 4-5 hours, and more than 5 hours is a batlithium battery with a higher cell count. , 8 cells, 9 cells, etc.
1. Battery Life: The average computer battery life is 3.4-4 hours = 6 cells, and more than 5 hours is 9 cells. 9 cores work longer, 6 cores usually work for more than 2 hours. If it is on standby, it may last more than 3 hours. If you play big games, 1 hour is enough. .
2. Capacity: 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 the capacity of 6 cells.
3. Battery size: The battery core is generally cylindrical, with a diameter of about 2cm and a length of about 9cm. 6CM is a 6 cell battery.
Detailed information
In principle, the more batteries the better, but there are otherrestrictions for two laptops with different battery cell numbers, usually those with more batteries have a longer lifespan. ?
In addition, some friends familiar with laptops will pay more attention to the size of the “mAh” battery unit when choosing products. “mAh” is the unit of battery capacity, and its Chinese. the name is in millimeter. Safe time.
In general, you may think that a battery with a large mAh unit will have a longer lifespan. But the real situation is not the same. You can often see numerical battery ratings such as "6 cell 4400 mAh" and "4 cell 2200 mAh" on laptop batteries. Over time, everyone believes that the capacity of 4400 mAh or 2200 mAh directly determines the capacity. laptop working time.
But that's not really the case. The unit that actually measuresThe battery capacity should be regarded as "Wh", whose Chinese name is "Wh". Of course, "Wh" and "mAh" are closely related by the following formula: Wh÷V×1000=mAh It should be emphasized that the unit of measurement of the power consumption of the electrical appliance itself must be the power, that is to say power. "Watt".
