Laptop batteries can keep your computer powered, even without being plugged in an electric outlet. You don’t have to walk with a laptop cord everywhere to use your computer as long as you have a reliable laptop battery (Chargeur D’ordinateur Portable Asus). But, there are factors that you need to consider before choosing the best laptop battery.

Considerations When Buying a Laptop Battery

The compatibility of a battery to the laptop is essential for efficiency and lifespan. Some batteries are manufactured for specific laptop models; it is vital to check if the battery matches your computer by comparing the model number of your current battery with the ones listed in the compatible model list. This information can be found on the manufacturer’s website. Other factors affect the service life of battery;

1. Capacity

The capacity is the level of energy a battery possesses; check the battery energy ratings from reviews from other customers. The energy capacity is usually measured in milliamperes; the greater the capacity, the longer the battery will stay powered. An average laptop rates approximately 5000 milliamperes when new.

The capacity of the battery decreases with time which also reduces its power time. That said, the power time is also dependent on the number of software installed on your laptop.

2. Material

There are four materials used to make batteries; Lithium-Ion (LiON), Lithium-Ion Polymers (Li-Poly), Nickel Cadmium (NiCad), and Nickel Metal Hydride (NiMH). LiON and Li-Poly have the best ratings for their energy capacity and lightness. Remember always to check the compatibility of your laptop regardless of the ratings.

The NiCad and NiMH are both big, but the NiMH types have a longer power time than NiCad batteries.

3. Refurbished or New and Used Batteries

A refurbished battery has had its old cell renewed. Its performance might be just like that of a new battery, but the service life might differ. A refurbished battery is cheaper, but you may not get a warrant during its purchase. It is advisable to buy a new battery over a used one because the performance of a laptop battery decreases with time.

4. Branded or unbranded

Branded batteries come with their brand names; they are the ones that come installed in new laptops. Unbranded or generic batteries are made to replace the branded ones. The companies that make branded and unbranded batteries use the same raw materials, making them almost identical in terms of performance and lifespan. Branded batteries are more expensive but with preferable warranties.

5. Lifespan

Every laptop battery brand has a lifespan; it is measured in terms of charging cycles. A cycle completes when the battery dies and fully gets recharged. An average laptop battery should go through a maximum of 1500 cycles and still be usable but won’t be as powerful. You can check the number of cycles your battery has using inbuilt software in some computers. If your laptop doesn’t have it, you can download free software for cycle counting.


A laptop battery warrant period differs from the brand; you should also check the battery’s safety measures. The importance of going through the safety measures is to ensure that all precautions are taken to protect the battery from damage.
