One distinct parameter for judging the overall efficiency of the laptop is its battery life. For the laptop to stand to its purpose, it has to remain mobile for prolonged times as well as be power efficient. Well, I wouldn't emphasize more on the fact that the whole utility of the laptop device lies in its battery. So, let's understand more about batteries instead.
Notebook batteries are composed of various materials, mainly NiCD (Nickel Cadmium), NiMH (Nickel Metal Hydride) and Lithium Ion Batteries. You can also buy 18650 lithium ion battery online.
The lithium ion battery is better than the former two in these following respects:-
* Lithium Ion ones are lightweight and compact, thereby allowing optimum mobility for your device.
* They have a higher energy density.
* Compared to NiCD and NiMH, Li-ion batteries have no memory effect and therefore are only charged to the amount that was discharged at the last cycle. This results in an incomplete bill. If it is not completely empty, there will also be a voltage drop. This causes the laptop to notify the user when the battery runs out before it runs out.
The lithium ion is the most efficient, but like all other energy storage devices, it ages. Therefore, they require suitable storage conditions for maximum performance and durability. Such batteries are damaged due to high temperatures. The extremely cold environment did equal damage. Therefore, room temperature is the most preferred.
