Laptop Battery Tester: Introduction and Checking

For one or the other reason, we often depend on the super-essential electronic devices, popularly known to us as Laptops. Some of us rely on it to finish our work, progress in our careers and put food on the table. Others of us depend on it to complete our school and college assignments and get those coveted grades. And still, others rely on it for keeping in touch with their loved and dear ones, playing games, or just surfing the internet. Regardless of how more or less critical our reasons are, it's apparent that laptops are a significant part of our existence in day to day life, and that means our laptop batteries are crucial, too. Because, without its battery, a laptop is completely worthless.

Hence, the most critical aspect that we should take care of while buying a new laptop is its battery durability and performance. Batteries provide power to our favorite electronic gadgets; however, they're not meant to last forever. Thus, it becomes vital to know how to test laptop batteries.

How can you tell if your laptop battery is bad?

No matter how sufficiently you care for your laptop's battery, it will someday die. Battery death can appear unexpected, but it doesn't have to. From encountering difficulty in  charging the laptop to enduring issu es of overheating, there are several signs to look for:

Limited Use Time

One of the most apparent signs is if it expires much faster than it used to. On average, a full charge should last for about eight hours or more, depending on your usage. If your laptop is hardly making it past a couple of hours, it's a sign that your laptop's battery needs replacing.

Frequent power issues. If your laptop powers off suddenly, and particularly after a recent charge, you can assume a malfunctioning battery is a cause. Try keeping a note of how frequently your laptop powers down on you to keep a check.

Slow Charging

If your laptop charges exceptionally slowly, it may also be a warning sign. A healthy and effective laptop battery will charge rapidly and maintain its power for a more extended period when it is not connected with the charger.

Unnecessary Overheating

Laptops generally cool themselves during use and dissipate excess heat.  If you frequently find your laptop getting heated, there's a strong possibility that your battery is struggling too hard and is unfit to cool itself. An overly hot laptop will often be quite noisy since the internal fans work overtime to cool the laptop.

System Notification

Nowadays, most laptops are already equipped with technology to check overall health. You can quickly check your battery's health by generating a battery check report and assess if it's time to replace your laptop's battery. Detailed steps and methods are further given below in the later section of this article, which you can refer to.
