A standard 18650* Lithium Ion (Li-Ion) or Lithium Polymer (Li-Po) cell operates at 3.6–3.7 Volts. By creating a series string of three, a total battery voltage for a laptop of 10.8–11.1 Voltage is achieved. This is as close to a 12V Standard as a modern laptop needs to have available.

How many volts is one cell of a laptop battery?
Nominal voltage of each cell is typically 3.6-3.85 V, the charging voltage is about 4.2-4.5 V per cell. The Li-ion phosphate cells have 2.9V nominal and 3.6V charging voltage. Note that because of the cell’s relatively high voltage, many low-power portable products can operate from a single cell.
What voltage is laptop cells?
Laptop batteries commonly have four 3.6V Li-ion cells in series to achieve a nominal voltage 14.4V and two in parallel to boost the capacity from 2,400mAh to 4,800mAh. Such a configuration is called 4s2p, meaning four cells in series and two in parallel.
What is the capacity of laptop battery cell?
The typical notebook battery has between 2,000 and 6,000 milliamp hours (mAh) of capacity. See milliamp hours. This describes the complete charge and discharge cycle of the battery.
What type of cells are in a laptop battery?
In a typical laptop battery, there are 6pcs of 18650 lithium-ion cells. An 18650 cell is just a cylindrical cell with a diameter of 18mm and height of 65mm (approximately).
What is 3 cell battery in laptop?
So a 3 cell battery will have 3 cylinders inside of it. A normal cell will have about 1.5v power outage, so a 3 cell battery would have 1.5*3 (4.5) volts being output when used.
How long does a 2 cell laptop battery last?
The approximate battery timing is 3 to 4 hours. Some customers who are using 2 cell batteries say that the battery timing is from 5 to 6 hours and some say that it is from 3 to 4 hours .
What are the specifications for a laptop battery?
Product specifications
| Specification | Description |
|---|---|
| Cell type | Lithium-ion (Li-ion) |
| Voltage | 14.6 V |
| Amp-hour capacity | 2850 mAh |
| Watt-hour capacity | 41.6 Wh |
What is mAh laptop battery?
Laptop batteries are rated by, Voltage (V) and Milliamp-hours (mAh). Voltage. Which is the rate at which energy is drawn from the battery, and Milliamp-hours represents the battery’s capacity. The Milliamp-hour rating Corresponds to the run time of the battery.
What is 6 cell battery of laptop?
1) Compatibility : This Battery is compatible with Dell Inspiron 1525 laptop .
DELL I1525 6 Cell Laptop Battery.
| Model Number | I1525 |
|---|---|
| Battery Energy | 48 Wh |
| Voltage | 11.1 V |
How long does a 4 cell lithium ion battery last?
The typical estimated life of a Lithium-Ion battery is about two to three years or 300 to 500 charge cycles, whichever occurs first. One charge cycle is a period of use from fully charged, to fully discharged, and fully recharged again.
What is the difference between a 3 cell and 4 cell battery?
Just answering the question taking all things as general then a 4 cell would be better . The 4th cell adds more juice than the 3 cell .
Are laptop batteries ion cell or metal cell?
Three types of batteries power the laptops you’ll find in service today, nickel cadmium (NiCad), nickel metal hydride (NiMH), and lithium ion (Li-ion), with Li-ion being the most common in newer laptops. Each battery type has a different chemistry for generating a charge and, therefore, different characteristics.
Is a laptop battery lithium?
Most of your electronic devices have lithium-ion batteries in them. This includes your smartphones, laptops, tablets, cameras, and strobe heads. All of these meet TSA requirements and can be carried on because all of these batteries are under 100 watt-hours (Wh).
Which battery cell is best?
NiMH batteries have replaced nickel cadmium (NiCd) batteries as the preferred cylindrical rechargeable battery. They offer higher energy capacity (up to 50 percent more) than NiCd batteries and avoid the high toxicity of cadmium.
Is a 4 cell battery good?
If you are using your laptop for office work or school projects, having four-cell batteries would be fine since they don’t require as much power and will last for long. The more cells a battery has, the better. It means longer life, and you can use your device for longer before having to charge it again.
What does 6 cell battery mean?
Incorporating six smaller batteries, 6-cells are about two-thirds the size of 9-cells, which have nine smaller batteries. A 9-cell battery may feel uncomfortably bulky on a smaller laptop. Your battery’s longevity depends on your computer’s hardware and how you use the computer.
Is a 6 cell battery better than a 3 cell?
Battery Endurance
The biggest difference between a 3-cell and 6-cell battery is that a 6-cell battery may last twice the amount of time. However, it is dependent on the amount of energy your netbook needs to operate.
What is 3 cell battery life?
The overwhelming answer was 5 to 8 hours. Some of the largest notebook vendors are crippling their netbooks by bundling them with 3-cell batteries.
What is the difference between 2 cell and 3 cell battery?
Comparing the capacity, we will see that the 3 cell battery is the better choice. The reason is that instead of 2 individual cells there are 3 individual cells inside the battery, so the capacity is increased. This can enable the battery to power the laptop up for a longer time.
How long will a 3 cell laptop battery last?
A three cell 42 Watt-hour battery at 11.1 volts will have at least 3780 mAh of capacity. Thus if it is discharged at a rate of 1C (1 Amp) it will last for approximately 3 hours.
