Powerbanks are an essential products for our Energy consuming gadgets..It is very difficult to maintain the battery charge throughout the day while using your phone to even half its potential. So, it is important to keep a backup supply always.

In this Instructable, i decided to use my old Laptop battery and make a mobile powerbank from the salvaged cells. A Laptop battery needs replacement every few years but all the Li-ion cells inside it are never damaged. They can be extracted and used for various other purposes.

Note: This PowerBank is only capable of charging Android devices. To charge an ios device it needs a special value of voltage (D+ = 2.76v & D- = 2.06v for 1A current draw and d+ = 2.0v & D- = 2.0v for 500mA current draw) at the data pins that can be easily made using a voltage divider circuit with few resistors. But since i needed it for android devices, so didn't worry much about providing voltage at data pins.

Step 1: Order Parts

Step 3: Prepare Li-Ion Batteries
In case you bought new Li-Ion cells, you can skip this step.

If you are also using an old Laptop battery like me, then you can proceed. The laptop batteries are made up of multiple Li-ion cells connected together in certain combinations. When the battery stops charging or becomes faulty, it has mostly been seen that only few cells get damaged, whereas all other cells work well. We will use those cells to make a powerbank at home.

Carefully open the laptop battery without damaging the cells inside.
Using wire stripper, cut the solder tabs connecting cells.
Separate each cells and clean them with a damp cloth to remove the adhesive.
Using a multimeter, check the voltage of each individual cells.
Discard the cells with voltage less than 2.5v as they might be damaged and will be difficult to revive.

Step 4: Connect the Cells

I like to diy very much. A lot of handmade things are very usefull in ordinary life. How to make different things? What craft of crafts should I choose? Constuction is anothe side of creativity. In this field you must be able to make insulation and padding, waterproofing and repair or reperation, fix and pluster ect. You have to know a bit about welding, installation or disassembly of different things.
