How Do Laptop Batteries Get Damaged

Laptop batteries are one of the most important parts of the computer, and yet they are often neglected and abused. Batteries are delicate things, and if not treated properly, they can be damaged irreparably. In this blog post, we will explore how laptop batteries get damage and what you can do to prevent it. From overcharging to leaving your laptop on all the time, there are a number of ways to shorten the lifespan of your battery. Be sure to read on to learn more about how to keep your laptop battery in tip-top shape.

What Is A Laptop Battery?

Laptop batteries are made up of rechargeable cells that provide power to the laptop when it is not plugged into an AC outlet. Over time, these cells can become damaged and no longer hold a charge, which can shorten the battery life of the laptop. There are several ways that laptop batteries can become damaged, including:

  • Overcharging: When a laptop is left plugged into an AC outlet for extended periods of time, the cells in the battery can become overcharged and begin to degrade. This can eventually lead to the battery no longer holding a charge.
  • Heat: Excessive heat can damage the cells in a laptop battery, causing them to lose their ability to hold a charge. Laptops that are used in hot environments or left in direct sunlight can be more susceptible to this type of damage.
  • Age: Like all rechargeable batteries, laptop batteries will slowly lose their ability to hold a charge over time. This is why it’s important to regularly calibrate your battery (see below) to prolong its life.

If you suspect that your battery may be damaged, it’s important to take steps to protect it from further damage. One way to do this is by calibrating your battery on a regular basis. Calibrating your battery helps ensure that it charges properly and maintains its full capacity.

What Are The Different Types Of Laptop Batteries?

Laptop batteries are available in a variety of shapes and sizes, each designed for a specific type of laptop. The most common types of laptop batteries are:

  • lithium-ion (Li-ion) batteries: These are the most popular type of laptop battery, as they offer a good balance between price and performance. Li-ion batteries typically last for around 2-3 years before needing to be replaced.
  • Nickel metal hydride (NiMH) batteries: NiMH batteries are slightly cheaper than Li-ion batteries, but don’t last as long – around 1-2 years on average.
  • Nickel cadmium (NiCd) batteries: NiCd batteries are the oldest type of laptop battery, but are now very rare as they are much less efficient than newer types of battery. NiCd batteries typically only last for around 6 months before needing to be replaced.

How Do Laptop Batteries Get Damaged?

Laptop batteries can be damaged in a number of ways. Overcharging is one of the most common, as it can cause the battery to overheat and eventually degrade. Discharging the battery too often can also shorten its lifespan, as can leaving it plugged in for long periods of time. Other potential causes of damage include exposing the battery to extreme temperatures, dropping or jarring the laptop, or using an incompatible charger.

How To Prevent Laptop Battery Damage?

Laptop batteries are susceptible to damage if they are not properly cared for. There are a few simple steps you can take to prevent damage to your laptop battery:

  • Avoid extreme temperatures. Laptop batteries should not be exposed to extreme heat or cold, as this can shorten their lifespan.
  • Don’t overcharge your battery. When your laptop is plugged in, it will continue to charge the battery even after it is fully charged. This can damage the battery and reduce its capacity over time.
  • Don’t allow your battery to drain completely. It is best to keep your laptop plugged in when possible, as allowing the battery to completely drain can also cause damage.
  • Store your laptop properly when not in use. When you’re not using your laptop, make sure to store it in a cool, dry place out of direct sunlight.


Laptop batteries are one of the most important parts of a laptop, and if they aren’t cared for properly, they can be easily damaged. It’s important to know how to care for your battery and what signs to look for that indicate it might be time for a replacement. With a little bit of knowledge and some proper care, you can keep your laptop battery working like new for years to come.
