How to Convert Battery Operated Devices to Plug-in
Today, an astonishing number of devices are battery-powered, ranging from tape recorders to cell phones and bouncy seats. While battery-powered devices offer the convenience of being portable, they also have several drawbacks. Regularly recharging or replacing batteries is expensive, and, in the case of the latter, wasteful of the environment. Consider rewiring your battery-powered device, by adding an AC adapter that allows you to plug your device into electrical outlets and use it for indefinite amounts of time.
Open the battery compartment of the battery-powered device. Remove and discard the batteries.
Use the utility knife to remove about half an inch of insulation from the end of the AC adapter wire, without actually cutting the wires. Unwind the wires, separating the positive wire (which is connected to the center connector) and marking it with electrical tape.
Connect the wires from the AC adapter to the battery-operated device. With a soldering gun, solder the positive wire from the AC adapter to the flat terminal in the battery compartment. Solder the negative wire from the AC adapter to the spring terminal.
Cut a hole in the battery compartment cover so that the AC adapter wire can run through and out of the battery compartment. You are ready to plug in your device, and run it using alternating current.
