Step 1: Disassembly
First Disassemble the power Bank carefully. You need to apply little bit of force but be carefull not to break the circuit board inside. Do not forget to take safety precautions.
Step 2: Checking for Problems and Errors
Here observing carefully in my case i found corrosion/rust over all my individual Li-ion battery . So in order to remove this use white vinegar and rub over the surface where corrosion/rust is present. This will clean the contact surfaces of the battery and now we are ready to solder all batteries together.
Step 3: Plan for Repair and First Charging!
Check the Charging PCB with the help of multimeter, whether you are getting desirable output voltage or not. The nominal voltage of Li-ion cells is 3.6V-3.7V. I am getting output voltage of around 4.1volt that is enough to charge li-ion battery.
Step 4: Calculation for New Capacity of Bank
In order to calculate overall capacity of bank we have to first determine the capacity of individual battery . So for this we have one formula:
Step 5: Packing and Testing
Enough Calculation, now its time to put all together. Pack the powerbank once again by installig batteries and other necessary parts.
