Laptop Battery Technologies


It goes without saying that the performance of a laptop depends a lot on its battery. After all, a laptop becomes mobile only when its battery allows for a longer runtime. With all the wide variety of choices in the market, it’s always good to be knowledgeable about the many types of batteries that are available so you can make the right choice.

The types of laptop batteries vary greatly according to the technology used to create them, the efficiency of their performance, and the hazards that come with their use. There are three popular kinds of laptop batteries that have been used over the years.

Nickel cadmium

The nickel cadmium batteries were used in old laptops. They are actually the first rechargeable batteries ever used in notebooks because for a relatively low cost, one can yield satisfactory output. However, as time went by, the NiCad battery lost its popularity over more environment-friendly types. One of the downsides of using this type is what is known as the memory effect. This refers to the decrease in a battery’s life when you charge it without letting it completely drain first. A NiCad battery can also be severely damaged when it is left plugged onto the charger long after it is fully charged.

NiCad batteries have relatively low capacities compared to the most modern ones. It’s not anymore used for newer notebooks because these batteries are heavier and pose more negative consequences than benefits.

Nickel metal hybrid

The nickel metal hybrid (NiMH) batteries are just a couple of steps higher than the NiCad ones. They have twice the energy output of the older type but are still susceptible to memory effect. NiMH batteries are still available these days. They are usually found in older laptops and manufacturers haven’t removed them from the market yet as many people are still attached to their bulky but reliable notebooks.

NiMH batteries are an improvement from the NiCad ones. They are much more reliable but again, you can’t leave them on the charger long after they’re fully charged nor can you charge them before they are fully drained.

Lithium ion

Lithium ion (LiON) batteries are the most popular types that are currently used in newer laptops. These batteries do not have the dreaded memory effect that their predecessors suffered from. They are also relatively lighter than the other two and have a better power output. The LiON batteries answer the demand for efficient power sources at a minimal production cost. Considering that notebook users live in a fast-paced environment, this is a great development that nobody can’t do without.

By far, the Lithium ion batteries are the recommended choice for today’s laptops. If you’re using a refurbished laptop that can take all types of batteries, you should consider getting a LiON battery. It weighs half as much as the older ones and promises more benefits that are more suited to the present.

However, it’s important to note that a laptop battery can only perform efficiently with proper use. It’s therefore important that you have to be mindful of proper maintenance and power-saving techniques to maximize your battery’s life.
