You can use two new wires and cut the rubber parts at both ends to expose the wire inside. Then form a circular loop with wires that you can use by twisting around the nodes of the power cell.
Step 2: For a temporary negative cable from your charging system, create loops at both ends of the cable. For one that will act as your positive wire, loop one end and leave other end as it is. To avoid confusion, you can label cables or use a color code to indicate their polarity.
Step 3: Using the negative cable, wrap the loop around the plug of the charger.
Pull the wire around the metal part of the assembly, and then seal it tightly with electrical tape.
Step 4: Then take the positive cable, try to make it bulky, and thicken the wires. Then apply some aluminum foil along the entire length of the wire. This will be a component of your charging system, which you plug into the opening of the charger .
NOTE. The structure should be like this: a small metal tube will have a positive cable inside, and then the negative circuit will hug it outside. You must also ensure that your positive cord is firmly compressed inside to avoid sparks.
