What is battery cell? How long is the usage time of each type of battery cell?

Cell battery is probably a factor that many users are interested in, before choosing to buy themselves a tablet or laptop because it is related to the time of use of the device. Let’s find out more details in the article below!

What is battery cell?

The battery cell on a laptop is actually a Li-ion or Li-Po battery. Each battery cell is a Li-ion or Li-po battery, the unit voltage is volts (V), unit capacity (mAh), cylinder diameter 18mm, height 65mm, relatively similar to a large battery (Battery D). . Multi-cell batteries have many batteries inside.

Is the battery cell a determining factor in the usage time of the device?

This means that the higher the number of battery cells, the longer it will last , but this is still not a decisive factor because of the constant improvement in technology of manufacturers, producing many screen technologies. screen, processor chip that optimizes energy efficiency or integrates smart battery management features on the device to help prolong the life of the device . In addition to the number of battery cells, users should pay attention to other technologies inside the machine to have a more objective view and assessment.

Common types of battery cells

All of the ratings below are rated below usage with common tasks such as listening to music, watching movies or playing games with average performance, the time will be different for each different model. Specifications are for reference only and are not guaranteed.

Lithium-Ion (Li-Ion) Battery

Lithium-ion (Li-ion) batteries are advanced battery technology that uses lithium ions as the main component of its electrochemistry. This substance is responsible for the exchange of ions between the electrodes (Anode and Cathode) like any battery.

Battery type	Screens from 11-13 inches	Screens from 14-15 inches	17 inch screen
4 Cells	2:30	2 o’clock	1 hour 40′
6 Cells	3 hours 30 minutes’	3 o’clock	2:30 p.m
8 Cells	Do not have	4 hours	3 o’clock
9 Cells	Do not have	4 hours 30	4 hours

Lithium-Polymer (Li-po) Battery

LiPo batteries do not use a liquid electrolyte , but instead use a dry polymer electrolyte , similar to a thin piece of plastic film. This film is sandwiched (actually a foil) between the anode and cathode of the battery allowing ion exchange.

Battery type	Screens from 11-13 inches	Screens from 14-15 inches	17 inch screen
4 Cells	4 hours	3 hours 30 minutes’	3 o’clock
6 Cells	6 o’clock	5 hours 30′	5 hours
8 Cells	Do not have	7:30 am	7 o’clock
9 Cells	Do not have	8 o’clock	7:30 am

Notes on using cell batteries

Users should limit the situation that the device runs out of battery (0% battery) but leave a part of the energy inside the battery, that part of the energy can help manage the cells in the battery while waiting for the user. Plug the charger. Avoid dead battery or failure to charge the battery.

Batteries can lose up to 80% of their capacity if left at a temperature of 60 degrees Celsius for 1 year , and at 20 degrees Celsius , the corresponding capacity loss is only 20% . Similarly, extreme low temperatures such as in freezing environments are also not good for battery life.
