The Different Types of Laptop Batteries

Different Types of Laptop Batteries

Same as other technologies of the world, the laptop battery technology is getting better and better day by day as well. They are producing more reliable and better batteries for the recent laptops. The earlier batteries were Nickel-Cadmium batteries that had a low energy density but their discharge rate was very high and longevity was high as well.

Then Nickel Metal Hydride batteries because of their perks took over the Cadmium batteries as the Ni-Cad batteries were environmentally unfriendly. Then the Lithium batteries came and stepped ahead from these Cadmium batteries by showing their different pros.

As a matter of fact, the new technology is made to give a more efficient performance as compared to the older one. So in this article techtrada will tell you about all the pros and cons of different types of laptop batteries. So let us have a look at the following:


1. Nickel Cadmium Batteries (NiCd)

The Nickel Cadmium battery is very much efficient in that it has the tendency to get charged and discharged 1000 times before being inactive. This statement clearly means that this battery comes with a life cycle of 1000 charges. But at that time these figures were considered perfect as these batteries have a longer life as compared to other batteries.

Although these batteries had some shortcomings so other technologies are preferred to be used in laptops. These NiCd batteries are now used on the radio, video cameras, and medical equipment as well.

  • You can charge them fast and easily. They do not have any problem with pulsating current, so there is no need for DC charge in specific.
  •  The number of charge and discharge cycles is high as compared to the other batteries. This cycle can be up to 1500 if the battery is maintained properly.
  • You can use them in a harsh environment. Their performance is very high, especially at low temperatures.
  • These batteries are pocket-friendly and are available in almost all sizes.
  • Because of the chemical nature of the compound, these batteries have a lower energy density as compared to other batteries.
  • They have a relatively high self-discharge rate, especially when they are stored for a long time period.
  • They face a phenomenon “memory effect” in which the charging ability of the battery lowers down and it is a very major con. To avoid this situation you have to discharge the battery completely before putting it on charge.
  • These are highly unfriendly to the environment because of their radioactive materials.

Nickel Metal Hydride Batteries

2. Nickel Metal Hydride Batteries (NiMH)

These batteries are preferred to be discharged half as compared to the NiCd batteries. The Nickel Metal Hydride batteries are environmentally friendly and have more plus points in the same size as Nickel Cadmium batteries.

The life of these batteries is much lower than the earlier laptop battery technologies. The major use of these batteries was in laptops at one time but now they are likely to be used in satellite applications. Now let us have a look at the pros and cons of these batteries.

  • They are more powerful than other batteries because of their higher energy densities.
  • They do not show any storage issues and can be transferred in different temperature zones as well.
  • These batteries do not suffer from the deadly memory effect although their manufacturing is based upon Nickel.
  • You can easily recycle these environmentally-friendly batteries.
  • The main issue with this battery is its lifespan. You are not able to get more than 300 cycles that are also with the proper maintenance.
  • They consume more time for their charging than NiCd batteries.
  • Generate more heat while charging.
  • Increased temperature poses more of an effect on battery life.
  • These self-discharging and expensive batteries require more maintenance as well.

Lithium-ion Batteries (Li-ion)

3. Lithium-ion Batteries (Li-ion)

This is the most recent type of battery that is used in laptops nowadays. They are the best batteries to be used than the older battery types.

They possess fast charging options and you can charge them easily despite the short and long-term chargings. In today’s world, these Lithium-ion batteries offer the most promising and proficient performance among all the batteries.

  • They come with a very high energy density (almost double than the NiCd batteries) and are more effective in utilization and as well as in storage.
  • They are perfect in their discharge rate. If you leave them for a month they will get discharged only 10%.
  • These batteries do not require any kind of maintenance.
  • They have less battery cycle than the NiCd batteries as they offer almost 1000 cycles.
  • Li-ion batteries are consumer-friendly, budget-friendly, and eco-friendly as well.
    • The aging effect is the major downside of these batteries.
    • With time their performance decreases but the manufacturers are silent in this regard.
    • You can see many reasons for which laptops can catch fire, but these batteries are also highly flammable.
    • Though overcharging does not affect the life of the battery, it disturbs the performance of the battery circuit.
    • The cost of these batteries can be reduced by observing better manufacturing techniques.


At you are more likely to get all the information about the technology and technology-related products of the modern world. Here we provide you with all the knowledge and even solutions to your different technology problems as well.

In this article, we have shared information about the types of batteries that are being used in laptops across the globe. We hope that you have developed much sense of knowledge about these different kinds of batteries after reading this piece of writing.
