DC Adapter Plug
Secondary-cell (such as lead-acid and nickel-cadmium) batteries can be discharged and recharged several times. As a part of regular battery maintenance, a battery must be charged fully to rejuvenate the battery's internal electrode plates.
A DC adapter plug may be converted into a battery charger by cutting off the adapter tip and attaching battery clamp terminals or alligator clips to the adapter wires.
Instructions
1. Each wire's polarity is marked at the adapter tip.
Cut the tip off the adapter. Pull apart the wires until there is a six-inch separation between the wires, and remove 1/2 inch of insulation from the wire ends. Cut a piece of electrical tape, and place the tape over the positive wire lead.
2. Loosen and remove the top screws on both battery clamps. Take the first battery clamp, and place the end of the negative adapter wire into the hole created by removing the screw. Insert the screw, and tighten until the screw holds the wire firmly against the battery clamp. Write the word "negative" on this battery clamp.
3. Remove the electrical tape from the positive adapter wire. Take the second battery clamp, and place the end of the positive adapter wire into the hole created by removing the screw. Insert the screw, and tighten until the screw holds the wire firmly against the battery clamp. Write the word "positive" on this battery clamp.
4. Attach the positive battery clamp to the positive battery terminal. Attach the negative battery clamp to the negative battery terminal. Plug the adapter into the wall socket.
