The amount of scrapped lithium batteries from electronic products increases dramatically every year. With the popularization of personal laptops and the portability of laptops themselves, laptops have become an indispensable tool for everyday office workers and short video creators.
There are also a lot of discarded laptop batteries. Some people may ask: How to recycle and reuse the discarded laptop batteries? In fact, the discarded laptop batteries can still be used for DIY and turn waste into treasure.
Tutorial on how to turn laptop batteries into mobile power sources for smartphones and other devices:
Laptop Battery Disassembly
First, you need to take out the used laptop battery and then disassemble it. You can use tools such as a knife and a screwdriver to disassemble it and take out the internal battery .
After removing the rear casing, we can remove the battery cells inside the laptop battery.
Designing the battery pack
Choose the right battery combination based on the needs of the target device. Most mobile power supplies need to output 5V, which requires connecting multiple battery cells in series and using a step-down module to adjust the output.
If your battery cell is 3.7V 3000mAh, then connecting two cells in series will give you 7.4V 3000mAh, while connecting four cells in parallel will give you 3.7V 12000mAh.
Buy Power Bank Cases
After completing the above preparations, we will go buy a mobile power box . You can buy it according to your favorite mobile power appearance and functions.
After purchasing, we can completely remove the small battery in the laptop battery and install it in the mobile power box . Please pay attention to a detail during installation and make sure to confirm the positive and negative directions of the battery.
Insert the battery inside the laptop into the mobile power box
Use suitable materials to fix the battery cells together to ensure that the batteries will not come loose or cause contact short circuits in the housing of the mobile power supply.
After installation, we can test it, first check whether the connection between the entire battery pack and the battery management system is firm, and confirm that there is no short circuit.
There is a flashlight function on the mobile power box. We can turn on the flashlight function and see if it lights up to determine whether it is installed properly. If the LED light is on, it means it is successful.
But the debugging work is not over yet. Finally, connect the charging device (such as a smartphone) to test whether the battery pack can charge the device normally.
Summarize
There is almost no major technical difficulty in DIYing a laptop battery into a mobile power supply. I believe that friends can easily enjoy the fun brought by DIY and turn waste into treasure.
It is practical and simple to turn old laptop batteries into mobile power supplies, which can extend the battery life of your mobile phones and tablets.
