How To Properly Care For Your Laptop Battery?

Laptop batteries are designed to be used for a finite number of charges and discharge cycles. The number of charge cycles a battery can go through until it starts to degrade depends on the chemistry of the battery but is typically between 300 and 500.

Once a laptop battery reaches this point, it will start to hold less of a charge and will need to be replaced.

  • There are a few things you can do to help prolong the life of your laptop battery and get the most out of it:
  • Avoid letting your laptop battery drain completely before recharging. Laptop batteries last longest when they’re kept between 40% and 80% charged.
  • Avoid extreme temperatures. Laptop batteries don’t like to be too hot or too cold, so try to keep them in a temperature-controlled environment.
  • Don’t leave your laptop plugged in all the time. Overcharging can shorten the lifespan of your battery.

What To Do When Your Laptop Battery Dies?

Laptop batteries are one of the most important parts of your laptop, and also one of the most finicky. It seems like they never last as long as you want them to, and then they die suddenly without warning. So, what can you do to prolong the life of your battery and avoid that frustrating situation?

Here are a few tips:

1. Keep Your Battery Cool

Batteries dislike heat – it speeds up the chemical reactions inside them and causes them to degrade faster. So, if you want your battery to last longer, keep it cool – either by using your laptop in a cool environment or by investing in a cooling pad.

2. Use Your Laptop On AC Power When You Can

This one is a no-brainer – when your laptop is plugged in, it doesn’t have to rely on battery power, which means the battery will last longer. So, if you know you’re going to be working on your laptop for a long period of time, make sure to plug it in.

3. Only Charge Your Battery To 80%

You might have heard that it’s bad to let your phone or laptop battery die all the way to 0%. That’s not really true – what is bad for batteries is letting them stay charged at 100% for extended periods of time. So, if you want to prolong your battery’s life, only charge it up to 80% and then unplug it.

4. Avoid Using Your Laptop On Battery Power When Possible

This one is similar to the previous tip, but it’s worth repeating. If you can avoid using your laptop on battery power, do so – it will help prolong the life of your battery. Of course, there will be times when you have to use your laptop on battery power, but try to limit those occasions as much as possible.

5. Don’t Forget To Calibrate Your Battery

Calibrating your battery means draining it all the way down to 0% and then recharging it back up to 100%. This helps recalibrate the battery life indicator so that it more accurately reflects the true amount of charge in the battery. It’s a good idea to calibrate your battery every few months, or any time it seems like the battery life indicator is inaccurate.

6. Keep An Eye On Your Battery Health

Most laptops these days have some sort of utility that lets you monitor your battery health. This is helpful because it can give you an early warning if your battery is starting to degrade. If you see that your battery health is dropping, it’s a good idea to replace the battery before it completely dies.

7. Replace Your Battery When It Starts To Die

This one might seem obvious, but it’s worth repeating – once your laptop battery starts to die, it’s time to replace it. A new battery will not only last longer, but it will also perform better, which means your laptop will run more smoothly.

Laptop batteries are essential to the smooth running of your laptop, but they can be frustratingly finicky. By following these tips, you can prolong the life of your battery and avoid some of the most common frustrations.


Some Simple Tips To Help Your Laptop Battery Last Longer:

1. Use your laptop on AC power as much as possible. Running off of battery power will shorten the overall lifespan of the battery.

2. When you *do* need to use battery power, enable “Power Saver” mode in your computer’s settings. This will help conserve energy and extend your battery life.

3. Avoid letting your laptop’s battery drain completely before recharging it. Try to keep it above 20% for optimal longevity.

4. If you won’t be using your laptop for a while (a week or longer), store it with a 50% charge to help prolong the battery’s lifespan.

5. Keep your battery clean and free of debris. A build-up of dirt and dust can cause your laptop to overheat, which will shorten the battery’s life.

6. Avoid exposing your laptop battery to extreme temperatures, both hot and cold. Extreme heat or cold can damage the battery and cause it to degrade faster.

7. If your laptop is getting old, the battery may not be able to hold a charge as well as it used to. This is normal and to be expected with age. Try buying a new battery if your old one just isn’t cutting it anymore.

8. Some types of batteries are designed to be “sacrificial”. This means that they are designed to degrade over time so that they can protect the rest of your laptop from damage. If you have this type of battery, it’s best to replace it as soon as it starts showing signs of wear.

9. Laptop batteries are designed for a certain number of “charge cycles”. This means that you can only charge and discharge your battery a certain number of times before it starts to lose capacity. Once your battery reaches its maximum number of charge cycles, it will need to be replaced.

10. If you take good care of your laptop battery, it should last for several years. But eventually, all batteries will reach the end of their lifespan and need to be replaced.


Laptop batteries are notorious for dying quickly, but there are a few things you can do to make them last longer. In this post, we’ve outlined the main reasons why do laptop batteries die so fast and shared some tips on how to extend their lifespan.

We hope these tips help you get the most out of your battery! Have you tried any of these methods to improve battery life? What worked best for you?


Q 1. How do I stop my laptop battery from draining so fast?

A. There are a few easy ways to help improve your laptop battery life:

  • Reduce screen brightness or use the power-saving mode
  • Close unused programs and tabs
  • Avoid using your laptop on battery power for extended periods of time
  • Make sure your laptop is running the latest software updates

Q 2. Why do laptop batteries degrade so fast?

A. Laptop batteries degrade over time because of a chemical reaction that occurs within the cells. This reaction is caused by a build-up of lithium ions, which produces heat and causes the battery to swell. As the battery swells, it starts to lose capacity and eventually fails.

Q 3. How long should a battery last on a laptop?

A. The average laptop battery life is around 3-5 years. However, this can vary depending on how often you use your laptop, the settings you have it on, and other factors.
