They are normally held in by double sided tape or connected using metal tabs.

Then carefully cut the tabs/ wires that are connected to the charging circuit and between the cells using a Wire Cutter.After separating the chairing board I kept it for future tinkering.

I found 6 18650 Li Ion batteries manufactured by Samsung.The capacity was 2200mAh.

The two batteries are wired in parallel, and 3 parallel packs are connected in series for the desired voltage and mAh.

Then separate the individual cells.

First twist each parallel group and separate them by using a cutter.

Identify the good cells



1. Measure cell voltage. if it's less than 2.5v, throw it away.

2. Charge the cell. if it gets hot during charging, throw it away.

3. Measure cell voltage off the charger. verify it's between 4.1 and 4.2v.

4. Measure cell voltage. if it's fallen less than 4v, throw it away. Otherwise record the voltage.

5. Measure cell voltage. if cell voltage has fallen more than 0.1v from the recorded voltage, throw it away.

Any cell that hasn't been thrown away by doing the above test is considered to be good one.

You are almost there now insert the battery inside the slot provided in the case and taking note of the polarity

The positive terminal of the battery should be towards the charging board.Sometimes polarity is marked inside the case.

Then put it for charging by using the USB cable provided in the packet.

Attach the key chain with the case.
After charging test the USB output voltage by using a CHARGER Doctor.

The output voltage is 5.06V which is good for smart phones,Tablet or any other gadgets.

Finally the power bank is ready to use
