How To Hack a Dead Laptop battery

As far as we know, the new 6 cells laptop battery die after 600-800 charge cycles. Then we spend roughly $80 or more to order a replacement. It’s too expensive, and these dead laptop batteries can pollute our environment if we do not dispose of them properly.
Steps
1

Disconnect the battery from your laptop. There should be 2 catches, slide them to unlocked and slide it out.
2

Pry the battery apart. You may also need some patience and a sharp flathead screwdriver or a butter/putty knife.
3

You will see 6-8 cells connected to a circuit board. That is the battery controller. Look near the connector to find the board, and trace the wires. Carefully examine every cells by a multimeter to ensure the cells are fully discharged.
4

Make a note of where the wires connect to. This is important.
5

Use a soldering iron/electric welding tool to separate cells from the wires. Then take them out of the case.

6

Then solder/weld the new cells together. Remember to refer back to the note you made in Step 4.
7

Put the new cells into the case. Solder/weld back the wires and cells.
8

In the end put both rows of cells back together. Let it rest for about 48 hours.
9

Your hack is complete! Insert your battery and start charging. Turn it on, and you’re back in business!

 

Note
It’s a nice DIY hack, but only if you have an older style laptop. Most of the new ones have custom flat cells, I haven’t seen many of those on sale except OEM. Even worse on the newer ones the battery isn’t even accessible without disassembling the laptop.
