The laptop battery plays the most crucial role in powering your device. It stores electrical energy, which is availed when you power on the device, ensuring it runs smoothly. Without it, you will be forced to connect your computer to an external power source, which is inconveniencing.

No matter how good your battery is, it comes a time when you must replace it. And today, we will share some signs to look for if you are still determining whether you need a new battery.

When You Should Get Your Battery Changed

Buying laptop replacement batteries is not easy for many people. However, it is necessary if you want to get the best experience from your machine. Here are five signs that your laptop battery is no longer viable.

  1. Short battery life

Think of how long your battery used to last on a single charge. You could use it for several hours, sometimes even the whole day, without recharging. But now it only goes for an hour or less. That is a dead battery and must be replaced immediately as it will give you the worst performance experience.

  1. Overheating

Never use a battery that is overheating. It could be that the battery has short-circuited, or some leaking gasses are reacting to raise the temperature. Understand that extreme temperatures can lead to a battery explosion, which could damage your laptop and other valuables or even injure people. Avoid such risks by investing in a high-quality replacement laptop battery.

  1. Swollen battery

Gas leaks inside the battery compartment exert pressure on the battery cover, forcing it to expand. This leads to swollen batteries. You should discontinue use and dispose of such batteries immediately, as they may explode. It is safer to have a replacement laptop battery at hand.

  1. Physical damage

If you see obvious signs of breakage on your laptop, discontinue its use immediately. For instance, a broken seal for and battery cover can cause a catastrophic interaction between the internal battery components and the outside environment. The last thing you want is to have to buy a new laptop altogether because you used a faulty battery.

  1. Age of the battery

Batteries, even the most expensive ones, have a specific lifespan. For lithium batteries, it could be 500 to 1000 charge cycles or about three years. More advanced battery chemistries can go on for over five years, but they will come to an end. Replacing an old dead laptop battery is the only solution for such issues.
