How Long Do Laptop Batteries Last Before Replacing? & How To Prolong It!

The usefulness and portability of a laptop will depend on how great the battery is. Because no matter how great your laptop is, if the battery is weak, the laptop won’t be as useful or as enjoyable as it should be.

In this article, we will discuss how long you can expect your battery to last for before it needs replacing and how to make it last even longer.

How Long Does a Laptop Battery Last Before it Needs Replacing?

A laptop battery usually lasts between 2 to 4 years on average, which is around 1000 charges, but this could be shorter or longer depending on how you use it. The most common sign that a laptop battery is in need of replacement is if your battery doesn’t last as long as it once did, and you find yourself charging it more and more.

How to Check Your Laptop Battery Health

How Can You Take Care of a Laptop Battery to Help it Last Longer?

Whether you like it or not, your laptop battery will get weaker as it ages. Sometimes, the battery will also get weaker if the laptop is not used correctly.

In this section, we will provide some tips on how to take care of a laptop battery so it will last longer.

  1. When you buy a new laptop, make sure to leave it plugged in for at least 24 hours when charging it for the first time.
  2. Never drain your laptop battery. Since your laptop battery has finite charge-discharge cycles, it is best to charge it as soon as the battery level gets low. I charge my laptop once my battery gets to around 30%.
  3. Avoid overheating your laptop as this may degrade the battery life. Charging in a tight space like the top of the bed will restrict the airflow trapping the heat inside the laptop.
  4. Utilize power-saving options more often. If your tasks do not require too much power, you can set it to the lowest level.
  5. Adjust the screen brightness accordingly. Brighter screens will require more power to operate.

When is the Right Time to Buy a New Battery?

The perfect time to buy a new battery is when you notice that the battery life is not just as good as before. A good battery should last for up to six hours when fully charged but this does depend massively on what you are using the laptop for. If you are running games or 4K video editing then expect the battery to need recharging much sooner.

If your laptop battery drains very quickly when just browsing the net or watching YouTube, it’s time to consider getting a new battery.  But always be careful when picking up a new battery as there are many fake and poor-performing batteries on the market right now. Always buy from trusted stores.

Whilst discussing laptop batteries I suggest that you read this article I have written which contains some great tips on how to stop a laptop’s battery from draining fast. Not only will these tips prolong the periods when you need to recharge, but they will also help the laptop battery last even longer before it needs replacing.

Some Laptops Have a Removable Battery and Some Don’t

One of the benefits of owning a laptop is that you can always change its battery. That is especially the case for laptops that have removable batteries.

Since the batteries of these laptops can be removed without opening the base of the laptop, it is so easy to replace them.

However, some laptops have batteries installed inside the laptop. But the good news is you can always change the batteries of a laptop whether it’s removable or not.

To replace the non-removable battery, you have to open the laptop carefully, but doing so will automatically void the warranty.

You should be able to find a tutorial on how to replace a battery for just about any laptop model on YouTube.

If you don’t know what you are doing and don’t want to risk it, just take it to your nearest technician so they can replace it for you.
