How to Replace Laptop Battery Cells

Replace Laptop  Battery Cells

Today, this post will discuss the method of replacing laptop battery cells. You will get to the best way to replace laptop battery cells so you can use your laptop as long as possible.

A laptop is the most used and important piece of equipment in today's office environment. They are used for word processing, email, social media, web browsing, and more. They are also used by professionals in various fields, including architects, engineers, doctors, lawyers, accountants, financial planners, and even students. 

And yet, one of the most overlooked components of a laptop is the battery. Without a battery, you'll be forced to buy a new laptop, and that's a huge expense. Suppose you don't have a budget to buy a new battery. So, don't worry. We provide you with the method to replace laptop battery cells. Follow the instruction given below step by step for secure battery cell replacements. (Read here the best gaming mouse)

Which tools you'll need to replace the laptop battery cell?

Laptop  Battery Cells tools

Before starting a replacement, you will need some tools and materials.


A multimeter is a device used in electronics to test and measure voltage, current, resistance, and other electrical characteristics. It's used to test the power supply output, measure the circuits' voltages, or check the continuity of wires. 

A multimeter's main purpose is to check an electrical circuit's voltage. It is done by connecting the probes to the circuit and measuring the voltage across them. You can also measure current with a multimeter, which requires special equipment. Multimeters are used in a variety of applications, such as in batteries.


A plier is a tool for grasping, holding, or manipulating objects. It is commonly used in various settings, including homes, workshops, or offices. Pliers are made of two handles that are connected by a hinge. The plier's jaws are opened and closed by gripping the handles and squeezing or releasing the hinge.

Soldering Iron:

A soldering iron is an electric tool used to melt solder so that it can use to join two metal surfaces. The iron tip is heated to a high temperature, and then the solder is melted and applied to the joint. After the solder cools, the joint will be strong and conductive.

Soldering irons come in various shapes and sizes, and the right one for you will depend on the project you're working on it. You can find soldering irons at most hardware stores or online.

Open Battery Pack without damaging

Opening a battery pack without damaging it can be tricky. You don't want to slash it open with a knife, but you also don't want to be stuck with a battery that won't work. Here's a quick guide on how to open a battery pack without damaging it.

First, look at the battery pack and identify the seam where the two halves of the pack meet. You'll likely see a line of raised bumps running along this seam.

Next, insert a sharp object like a knife or a screwdriver into the seam. Be careful not to insert it too deeply - you want to make a small slit in the plastic.

Once you've made a slit, you should be able to peel the two halves of the battery pack apart. After two halves, it will automatically open up. You can remove the battery carefully because it contains connections with circuits from the case.

STEP BY STEP: Replacing old battery cells with new ones

After opening the battery case, the battery maybe shows between four to eight cells connected in a parallel method. 

Check the cells by Multimeter. If any cell has low voltage, you need to replace it. Then remove the cell carefully by using the plier.

After removing the cell, you need a new cell with the proper voltage and connect it properly using the soldering iron. Before using it, make sure the soldering iron is preheated. 

Once you replaced the dead cell, you placed the cells into the plastic tray.

Now you assembled the battery case with industrial glue and should install the case for the laptop. Before using the new cells, make sure they are charged overnight.


In conclusion, Lithium-ion batteries are the most popular type of battery used in laptops. They have a longer life cycle than other types of batteries. Also, they are more efficient than other types of batteries. Ensure that the substitutions are OEM! Successful publicizing, ridiculously high limits, missing weight data, and modest costs signify that the batteries are fake.

The new batteries shouldn't have the same limit as the first ones. They should be marginally higher, not surpassing the most extreme allowable charging current.
