Having a laptop with a dead battery can be frustrating, especially when you need to use it on the go. But did you know that you can actually repair your laptop battery at home? In this article, we will guide you through the steps on how to repair your laptop battery and get it working again.
What Causes Laptop Battery Damage?
Before we dive into the steps of repairing a laptop battery, let's first understand what causes laptop battery damage. There are a few factors that can cause laptop battery damage:
1. Overcharging
Leaving your laptop plugged in for extended periods of time can cause overcharging, which can lead to battery damage.
2. Extreme Temperatures
Exposing your laptop to extreme temperatures, such as leaving it in a hot car or in direct sunlight, can also cause battery damage.
3. Age
Over time, laptop batteries will naturally degrade and lose their capacity to hold a charge.
Steps to Repair Laptop Battery
Now that we understand what causes laptop battery damage, let's move on to the steps on how to repair your laptop battery:
1. Remove the Battery
The first step is to remove the battery from your laptop. Make sure your laptop is turned off and unplugged before removing the battery.
2. Clean the Battery Contacts
With a clean cloth or cotton swab, gently clean the battery contacts on both the battery and the laptop. This will help ensure a good connection between the battery and the laptop.
3. Check the Battery Voltage
Using a multimeter, check the voltage of the battery. A healthy laptop battery should have a voltage between 12.6 and 12.8 volts.
4. Discharge the Battery
Connect a 12-volt light bulb to the battery and let it discharge completely. This will help reset the battery's memory and improve its performance.
5. Charge the Battery
Once the battery is completely discharged, charge it back up to 100%. You can use a laptop charger or a battery charger for this step.
6. Test the Battery
Finally, test the battery by inserting it back into your laptop and turning it on. If the battery is working properly, it should hold a charge and allow you to use your laptop unplugged for several hours.
