HELLO MY FELLOW ...(I AM WAQAR)....!

TODAY, I'LL SHOW YOU HOW TO MAKE A POWER BANK USING OLD LAPTOP BATTERIES.

WHY ?

TODAY ALMOST EVERYONE HAVE A LAPTOP & EVERY LAPTOP HAS A BATTERY.

AFTER USING IT FOR SOMETIME THE BATTERY GET WEAKER OR DAMAGED.

THEN WE HAVE TO BUY NEW ONE ,

SO, JUST DON'T THROW THAT BATTERY FOLLOW MY INSTRUCTION ONLY ON INSTRUCTABLES.

& SEE HOW I REUSE THAT DEAD LAPTOP BATTERY TO MAKE POWER BANK.

Step 1: REQUIREMENTS

MATERIALS REQUIRED

1 DEAD LAPTOP BATTERY

1 POWER BANK (CHEAPEST)(http://www.snapdeal.com/product/rujve-a5-2600mah-p...) about 60-70 rupees only for bulk order without cells.

TOOLS REQUIRED

1 LONG NOSE PLIER

1 WIRE CUTTER

1 KNIFE

Step 2: OPEN LAPTOP BATTERY FOR HARVESTING CELLS

JUST OPEN LAPTOP BATTERY WITH PLIER & KNIFE USE YOUR MUSCLE POWER .

JUST MAKE SURE TO NOT GET HURT WITH PLASTICS.

Step 3: DISCONNECT THE CIRCUIT & ALL CONNECTIONS

USE YOUR WIRE CUTTER TO CUT OUT THE CIRCUIT (WE'LL USE IT ANOTHER PROJECT)

AND ALSO DISCONNECT THE PARALLEL & SERIES CONNECTION OF BATTERY PACK (CLEAN THE SHARP EDGES FOR SAFETY)

Step 4: CHECK THE VOLTAGE OF CELL

JUST CHECK THE VOLTAGE OF CELL WITH MULTI METER OR ANY OTHER

ABOVE 3 VOLTS CELLS ARE GENERALLY GOOD .

USE THEM FOR YOUR POWER BANK

Step 5: INSERT CELL INSIDE POWER BANK

USE YOUR KNIFE TO OPEN THE BACK COVER OF POWER BANK .

(MAKE SURE YOU DON'T TOUCH THE CIRCUIT WHILE OPENING )

JUST INSERT OR SOLDER CELL INSIDE POWER BANK WITH CORRECT POLARITY

(THE LONGEST WIRE IS GENERALLY NEGATIVE & OTHER ONE IS POSITIVE)

Step 6: CONNECT YOUR PHONE TO POWER BANK

CONNECT YOUR PHONE TO POWER BANK VIA USB CABLE

(IF PHONE IS NOT CHARGING DON'T PANIC JUST CHARGE THE POWER BANK WITH YOUR MOBILE PHONE CHARGER THEN CHARGE THE PHONE)


THANKS...


JUST COMMENT FOR ANY QUESTION OR SUGGESTION

IF YOU LIKE MY WORK JUST HIT THE LOVE BUTTON....

You took cell of 3.5v only , does it charge mobile ?,,,,
Yes ,<br>It will surely charge<br>But how much capacity of cell is different question<br>Which can only be known by capacity testing (which you can find on my YouTube channel WAQAR Alam)<br><br>https://youtu.be/WohHiMq4scA
<p>it's a great project buddy <br>but i think if you make it how to make a power bank from scratch using dead laptop battery would be better :)<br>why i should buy a power bank then replace it's battery with the laptop one what if the power bank body doesn't fit with the laptop battery :D</p>
good stuff Buddy !
