by Gary

Original dell batteries are known for their durability, incredible capacity, and low weight. The batteries can last for a long time, and they do not wear out faster. Thay is why, the market is packed with such batteries. However, you may want to get some knowledge on a wide range of laptop battery types.

Types of laptop batteries

There are three main types of laptop batteries in the market. They are:


Nickel-cadmium laptop batteries, also known as NiCad batteries, are the oldest type in the market. They offer incredible performance, and for a while, they were the most popular product in the market. However, over the years, clients discovered the numerous downsides of this type of batteries, causing them to frown upon them. The most common issue with NiCad batteries is that they suffer from the Dreaded Memory Effect. The Dreaded Memory Effect is where users have to wait until the battery is completely empty before they can recharge. They also tend to increase in size over time because of heat. For this reason, most manufacturers do not use NiCad batteries on their products recently.

2.Nickel-metal hydride

Nickel-metal hydride batteries were introduced when NiCad laptop batteries lost their popularity. Compared to NiCad batteries, NiMH batteries are long lasting. The one issue that manufacturers were not able to resolve with NiMH batteries is the Dreaded Memory Effect. For this reason, the batteries also lost popularity after a while.


Lithium-ion laptop batteries are the most popular type in the market. Their popularity can be attributed to the fact that they do not suffer the Dreaded Memory Effect issue. This means that you do not have to wait for the battery to go down completely to recharge. Lithium-ion batteries also offer a rapid-charging effect for times when you are in a rush. They also offer numerous other advantages like the fact that they are lightweight. It also helps that lithium-ion batteries are environmentally friendly. So far, they are the best option, and there haven’t been any significant downsides.
