Do Laptops Have Lithium Batteries?

Yes, laptops use lithium batteries. These batteries are why you can carry a smartphone or a microcomputer in your bag. Since the invention of Lithium batteries, communication has been revolutionized. 

Have you ever wondered how we can develop super-slim phones and electric cars now? 

Yes, all thanks to the lithium battery!

We vastly use lithium batteries because they are:

  • Highly efficient
  • Charge for longer
  • Much less toxic than other batteries
  • Portable
  • Great with energy-storing capacity
  • Smaller and lighter as compared to traditional battery types
  • Practical and powerful
  • Less expensive

Lithium batteries have replaced the previous generation Nickel-Cadmium batteries, and rightly so! (You’ll get more detail below)

What Are Lithium Batteries and How Are They Different From Ordinary Battery?

Lithium batteries are the latest generation batteries that use lithium to hold a charge. These batteries are more powerful and portable than previously used batteries.

Lithium batteries work on some simple chemistry rules. Since lithium is the lightest metal in the whole periodic table, it is eager to lose electrons. The lithium acts as a positive electrode, and the graphite is the negative one. The lithium-ion transfers the charge between the two electrodes in the battery. 

The main difference between lithium-ion batteries from nickel-metal or nickel-cadmium batteries is their lack of memory effect. The memory effect reduces the longevity of the battery. Lithium, however, has self-discharge properties, due to which it retains more energy. 

Therefore, lithium batteries in laptops are far better than other ordinary batteries.

What Type of Lithium Battery is Used in Laptops?

Broadly speaking, there are two types of lithium batteries, Lithium Polymer battery (Li-poly) and Lithium Ion (Li-ion). Li-poly uses a polymer instead of a liquid as an electrolyte. These polymers are semi-solid with high conductivity. 

As the name suggests, the Li-Ion variant uses the reduction process of lithium ions to supply energy. The reversible reduction phenomenon makes it portable. 

Among these two, Laptops use lithium-ion batteries. These batteries are rechargeable, unlike the Li-poly variant. Therefore, you can commonly see them on tablets, smartphones, laptops, and cameras. Li-poly batteries are not used in laptops, but you can spot them in watches, portable non-rechargeable cameras, etc.  

How Do I Know if My Laptop Has a Lithium Battery?

The easiest way to determine if your laptop has a lithium battery is to read the data plate. Simply turn off your computer and take out the battery. You will find the information listed on its plate. The companies list this information for safety and servicing.  

Generally, a lithium battery will be smaller than ordinary batteries. However, you can confirm by referring to the printed material. It would mainly indicate the following:

  • Type of battery (lithium-ion or not)
  • Model number
  • Part number
  • Serial number
  • Date of Manufacturing
  • Nominal voltage
  • The capacity of the battery
  • Service weight
  • Chemistry
  • Inputs and output current
  • Hazard symbols
  • Contact information of the company

95% Laptop have Lithum Batteries due to its portability, longevity and reliability

Are Lithium-Based Batteries Safe?

Lithium-based batteries are usually safe and won’t fail. The batteries also don’t pose any danger if they are used appropriately. However, the battery should not be defective or damaged. 

Lithium batteries can get damaged from improper storage or charging. If the battery is not operated safely, it can cause an explosion or fire hazard. 

Although it is less likely, you can take the following measures to prevent any unsafe incident.

  • Make sure that the battery in your laptop is grounded. Connect it directly to an outlet for recharging instead of using a power cord along with other devices. It reduces the risk of short circuits. 
  • Don’t let the battery near extremely high or low temperatures. For instance, higher than 130 degrees Fahrenheit, like heaters, open flames, etc. It can cause the battery to become overheated and explode.
  • Take caution while handling a heated battery. If it comes directly in contact with the skin, the hot battery can cause skin burns.  

Lithum Batteries are more safe than any other type of batteries

For more information on preventing explosion or fire injury from lithium batteries, refer to this document by OSHA!

What is the Lifeline of Lithium Batteries?

A lithium-ion battery can last for almost 3 to 5 years. It also means 300 to 500 charge cycles. A charge cycle is a duration in which the battery fully charges, fully discharges, and then fully powers again. 

However, the exact lifeline of the battery depends on its use and maintenance. Certain factors can increase or decrease the lifecycle of the lithium battery. The battery’s lifespan reduces due to improper or over-charging, extreme weather conditions, and long-term use.   

How to Prolong Lithium-based Batteries?

You can follow some simple tips regarding lithium batteries to prolong their life. Make sure you take care of the following things.

  • While charging the battery, follow the 40-80 ratio. You should not power the laptop battery above 80 or below 40. The batteries suffer tension at the endpoints of the charge; thus, their lifespan reduces. 
  • Avoid any kind of physical damage to the battery. It includes but is not limited to crushing, puncturing, or dropping the battery.  
  • Do not expose the battery to ultra-high or low temperatures. 
  • Use a designated lithium-battery charger.
  • Close the extra windows and apps in your laptop to conserve energy. It is also better to keep the laptop lid shut when not in use. 
  • Follow the safety instructions of the battery by the manufacturer.
  • Store your battery in a cool, dry place. 
  • Charge the battery for less than one hour if you use it extensively. Otherwise, charge it for at least one hour once every three months.   

Lithium Battery Advantages and Disadvantages

Your portable devices such as laptops and smartphones are powered by different types of batteries. And these batteries provide DC power to your portable device. When we talk about the multiple types of batteries that power our laptops, lithium batteries always come to the rescue.

Let’s first understand what a lithium battery is.

There are two types of lithium batteries commonly used: lithium-ion batteries and lithium metal batteries. The key difference between these two batteries is that lithium ion or lithium ion batteries are of the rechargeable type. On the other hand, lithium metal batteries are not. Common examples of lithium-ion batteries are laptop batteries, phone batteries, camera batteries, and many others. On the other hand, typical examples of lithium metal batteries are watch batteries, some non-rechargeable camera batteries, etc.

Does the notebook have a lithium battery?

Well, the short answer is yes!!

To be more precise, Lithium Ion is the type you will mostly find in modern laptops. Indeed, this is the kind of battery you would like to install in your laptop. This type of battery is lightweight and performs better than other types of batteries. Unlike nickel-metal hydride or nickel-cadmium batteries, lithium-ion batteries don’t have the dreaded “memory effect”. Well, the memory effect is a feature of nickel-cadmium batteries that causes them to lose their ability to fully recharge if they are repeatedly discharged with the same amount and then recharged without being recharged before being fully discharged.

There is usually a quick-swappable lithium-ion battery option, which is good when you’re pressed for time. Last but not least, this type of battery is even more environmentally friendly than other types.

How to fix a laptop lithium battery?

Laptops are generally considered the best because of their portability, you have enough free space to carry your laptop anywhere you want. The components that make portable devices portable are nothing more than the battery inside it.

Despite advances in Lithium Ion battery technology, laptop batteries have proven to be one of the portable devices with a short life span of 2 years maximum / 300-500 recharges. After this period, the battery may die and require repair due to several reasons such as battery age, overvoltage, overcharging, etc. When this happens, your laptop may require you to connect to a powerful power source and, indeed, all the time. After disconnecting the AC adapter, the laptop may simply shut down. At this stage, it is always recommended to repair the battery to improve performance.

Here we will show you how to fix a dead laptop lithium battery:

1: Calibrate the battery.

Recalibration is required for an old battery that has dried out, not a new battery. Generally, people can always turn on their laptop and never let their battery run out. Because of this, the OS will not be able to measure the remaining charge. In this case, the system may display incorrect charge indicators. These are the indicators that tell you that your battery needs to be calibrated.

To calibrate a laptop lithium battery, follow these steps:

  • Charge your laptop to 100 percent to reach its full charge limit.

  • Disconnect the AC adapter from the notebook.

  • Do not turn off the notebook until its battery is completely discharged.

  • Turn off the laptop and leave it for about three to five hours.

  • Turn on the laptop in normal mode, and then charge it to 100 percent.

2. Cool down your notebook

Heat could be one of the reasons for the notebook’s lithium battery to drain. When you place your laptop in a very hot room, or do any intensive work on your laptop, a lot of heat can be generated inside the laptop. Since laptop batteries are prone to heat, the heat generated can directly affect battery life as well as battery performance.

Use the cooling pad to cool the surface of your laptop. Also make sure that the ventilation openings that generate heat are not blocked. Be careful not to damage the battery in the future.

3. Do a full recharge.

As with other electronic devices, the battery also degrades over time. When this happens, the battery drains fairly quickly and the ability to hold a charge is weakened, and finally the battery is discharged. You can do a full recharge and discharge frequently, as this can increase its lifespan.

Although recharging and discharging is known to shorten the life of new Li-ion batteries, you can try this on dead laptop batteries to make sure they work properly.

  • Turn on the laptop

  • Unplug the AC adapter.

  • Let the battery discharge to less than five percent.

  • Reconnect to AC adapter

  • Charge it for 48 hours continuously for a full charge.

How to properly use laptop lithium battery?

Below we provide some useful tips for proper care of your laptop’s lithium battery, so you should follow them as they can help you extend the life of your laptop’s battery.

  • Do not fully discharge the notebook after charging. The best advice is to keep your battery between 40% and 80%.

  • Make sure your laptop is not getting too hot and the cooling fan is working properly.

  • Update, most companies are looking for ways to improve battery life through software updates.

  • A few changes to your laptop’s power saving settings can make a big difference in how much juice you have left at the end of the day. And the less work the battery does, the better it will stay.

So these are very common tips that you should follow in order to properly use your laptop’s lithium battery. Sometimes even the smallest things can make a big difference.

Today we live in the era of technology. Almost every part of our daily life now depends on the use of smart devices. We even wake up with an alarm on our watch or cell phone. Among all these devices used in daily life, laptops are among the most important. These mobile computers have now become an office for some professions these days, without their laptops they can’t do anything, every file and document they had that was physical in the past has now become a digital document stored in laptops. So, these devices are essential in our lives.

Now let’s talk about these laptops, what works with them for hours, so that we work without any difficulty, sitting anywhere we want, without the need for an electrical outlet to connect the power cable, are the batteries inside these laptops. These rechargeable batteries have made our lives much easier and less hectic. How can these batteries take so long to charge these devices? what do they consist of? These are some of the questions that make people curious and we are going to reduce their curiosity by answering them here.

What type of battery do laptops have?

Notebooks use batteries to provide direct current to your notebooks. Lithium-ion batteries are currently the most popular. Two older types were used: nickel cadmium (NiCad) and nickel metal hydride (NiMH). Both of these two batteries suffered from the terrible memory effect that caused them to fail in laptops. The terrible memory effect is also known as the battery effect – this is what causes the battery to hold less charge, the batteries seem to remember less capacity. However, lithium-ion batteries are not known to have this memory effect at all. But if they are re-charged after being partially discharged, they may lose some of their capacity.

These lithium-ion batteries can be recharged 300-500 times, and they can stop the charging process after being fully charged through their internal circuit. Why is there lithium in these batteries? This is a common question that comes up when you hear their name. The answer is simple because lithium is the lightest metal with the highest electrochemical potential and the highest energy density for weight. All of these are most important for a laptop battery, and lithium is by far the only metal that falls into this category.

3.2V 20A Low temperature LiFePO4 battery -40℃ 3C Discharge capacity ≥70% Charging temperature: -20~45℃ Discharging temperature: -40~+55℃ Pass acupuncture test -40℃ Maximum discharge rate: 3C


These batteries originally used lithium metal, but have inherited stability issues, especially during charging. Because of this safety hazard, instead of lithium metal, these batteries now use lithium-ion, which is slightly less energy than lithium-ion, but safer. It was first used commercially by Sony Corporation in 1991 year. Its energy is twice that of the previously used nickel-cadmium alloy. Lithium-ion batteries are also low maintenance and require less self-discharge compared to their forebears i. e. nickel cadmium and nickel metal hydride. These qualities make them ideal for modern fuel measurement applications such as laptops and mobile phones.

Can holding a laptop make airplane mode dangerous?

There are several destinations where direct flights to the US require passengers to carry their laptops in checked baggage rather than carrying them in the cabin. Such practices are dangerous because these devices become much more dangerous when they are not astute and packed with so many things that make the environment hot and compact. This can cause batteries to ignite and this can become a serious situation because these devices are out of sight and cause fatal damage before they are noticed, and airplanes do not have the proper equipment to deal with such fires. batteries will be called.

If they are allowed to be stored in the cabin with the passenger, where the environment is cooled, and they are not packed, then they will be much less dangerous than packed with luggage. If any accident should happen to them there in the cabin, they will be properly disposed of, causing less harm or even no harm.

When they are inside the luggage compartment, they are close to each other, and they also have many other things that would increase the fire anyway if they appeared, and even turn into a small bomb with so many devices, located close to each other in a small area.

How do you care for lithium laptop batteries?

Properly caring for lithium-ion batteries, following a few guidelines, can extend battery life and help maintain health. The first thing to remember is to store the battery at room temperature. Make sure your laptop is not in an environment that is too hot or too cold, as this could damage the battery.

Low temperature durable polymer laptop battery high energy density Battery specification: 11.1V 7800mAh -40℃ 0.2C discharge capacity ≥80% Dust-proof, drop-resistant, anti-corrosion, anti-electromagnetic


separately, store it in a place where the temperature is maintained at all times, such as a refrigerator. Yes, the fridge can be a good place to store the battery separately from the laptop, at the bottom of the fridge instead of the top (freezer). Wrap the battery around so it doesn’t get wet. Or place it on a shelf to keep the battery out of direct sunlight.

Also avoid completely discharging the batteries and recharging the battery after a partial discharge, this can damage the battery, never charge it if the battery level is at least 30%. By following these simple steps, you can keep your battery safe.

Anyone who uses a laptop should get this basic knowledge to keep their laptop battery in good condition. These guidelines will help keep your batteries healthy and stored in a way that does not harm them and keep them in good working condition for a long time. What’s more, it also provides know-how regarding the composition of the battery, its pros and cons.
