Part 1. Laptop battery types

There are different laptop battery types, and they have their advantages and disadvantages. With time, laptop batteries will become smart and long-lasting. Here are some of the laptop battery types to choose from.

laptop battery types

1. Nickel-Cadmium (NiCad) laptop battery

Nickel-cadmium was the most popular battery for laptops in recent years. However, the battery has a very short lifespan and needs frequent replacements. Moreover, one major drawback of this battery is the memory effect. This means the battery will need complete discharge and charge to achieve maximum performance. Furthermore, the battery has harmful materials like Cadmium, which makes it less environmentally friendly.

2. Nickel-Metal Hydride (NiHM) laptop battery

It is an advanced form of nickel-cadmium (NiCad) and comes as a Cadmium-free version. NiMH batteries have less memory effect and come with high energy density. However, the battery has heating issues, and you cannot recycle it properly.

3. Lithium-ion (Li-ion) laptop battery

Lithium ion laptop battery is the most advanced battery with the latest battery technology. It offers minimal memory effect with high capacity within a compact size, making it an ideal replacement for laptop batteries. The lithium battery has a long lifespan of over 3 to 5 years. Therefore, you will not have to worry about frequent battery changes.

4. Lithium Polymer (LiPo) laptop battery

It is a laptop battery type similar to lithium-ion but lighter and thinner physically. This feature makes the battery ideal for smart and extra slim laptops.

Part 2. What are laptop battery specifications?

Proper knowledge of your laptop battery specifications is compulsory before installing a new one. Nowadays, almost every laptop has a lithium-ion laptop battery. However, verifying the battery’s specific model, rating, and voltage knowledge is mandatory. There are two ways to check the laptop battery specifications that are following:

1.On-Screen Laptop Battery Specifications
For this purpose, you must open the Windows command line, type powecfg/battery report, and press the Enter button. A file containing every detail about your laptop battery specifications will be saved on the laptop

2. Physical Inspection
Suppose your laptop is not turning on or to look physically. In that case, you will have to open the battery compartment of your laptop. You will find a label over the battery containing all the details about laptop battery specifications.

Every laptop battery has its unique specifications according to the model. Here is some general information to help you understand your laptop’s unique battery specifications.

laptop battery specifications

  • Battery Type: Information of battery types like lithium ion laptop battery (Li-ion) or lithium polymer battery (LiPo)
  • 용량: Measured in Milliamp hours (mAh) or Watt-hours (Wh), it indicates the energy the battery can store. Higher mAh/Wh values translate to longer battery life.
  • 전압: Typically 10.8V or 14.4V determines the power output and compatibility with your laptop.
  • Cell Configuration: The battery pack consists of individual cells connected in series. More cells often lead to higher voltage and potentially higher capacity.
  • Battery Serial no S/N: A unique serial number can indicate the specific battery model for the laptop.

Part 3. Laptop lithium battery price

The prices of laptop batteries can vary depending on many factors. Here are some of the factors that can determine a laptop’s lithium battery price.

  1. Laptop Model: The model of a laptop can play a primary role in determining battery price. The battery price will be high if a laptop is the latest, most expensive, and most limited series. On the other hand, the old model laptop lithium battery price can be affordable.
  2. Battery Capacity: Laptop lithium battery price can rise with high capacity (measured in mAh or Wh). However, a laptop with high capacity means the battery will last longer on a single charge.
  3. Brand: Laptop battery manufacturers can also determine the laptop battery price. You will have to pay high for well-reputed laptop battery brands.
  4. Quality: Higher quality batteries with longer lifespans and better performance may cost more.
  5. General Price Range: The general price range of a lithium ion laptop battery starts from $20 to $200. However, some models can cost more than $200 due to their uniqueness and the latest models.
