How to choose an external battery for your laptop?

One of the most important factors for the proper functioning of a computer is the battery. Therefore, the degree of autonomy of your PC depends on the quality of its battery. Therefore, you have the obligation to choose the battery carefully. The computer has become an indispensable working tool in all fields of activity. Find out in this article the key points to choose the battery for your laptop.

Battery voltage

Finding a battery with the same part number as the original battery is not enough. Among all the batteries, the most used on laptops is 10.8V. Nevertheless, manufacturers may use higher voltages. Batteries with different voltages cannot be replaced. If you install a battery with a lower voltage on a computer that requires a higher voltage or vice versa, the computer will not work. You can easily check the voltage of the battery and even take cheaps adapters, the letter V (voltage) is indicated on the nameplate next to the model designation.

Battery capacity

Battery capacity, generally, is expressed in mAh (milliamp-hours) or Wh (watt-hours). mAh is a unit of actual cell capacity. It is the amount of electricity delivered per hour by a current of 1 ampere. The higher the mAh/Wh, the longer the life of the battery.

Large capacity battery

The most common capacity of a standard battery is 4,400 mAh (48 Wh), usually 6 cells (10.8 V). Choosing a high-capacity battery allows you to increase the battery life (compared to a standard 4400 mAh battery) by more than 1.5 times (6600 mAh battery). By following the instructions above, you can choose the right battery and avoid delivery delays, replacements and the confusion of additional costs.
