Before opening your iPod, ensure that the hold switch is in the locked position. /Guide/Repair/iPod-Nano-2nd-Generation-Battery/422/all#s1806 Carefully insert an iPod opening tool in the seam between the metal casing and white plastic top. Lift the top bezel off the iPod. It's glued on using a mild adhesive, so some force may be required. /Guide/Repair/iPod-Nano-2nd-Generation-Battery/422/all#s1807 When removing the bottom bezel, be sure not to bend the plastic surrounding the dock connector. Carefully insert an iPod opening tool in the seam between the metal casing and white plastic bezel. Lift the bottom bezel off the iPod. It's glued on using a mild adhesive, so some force may be required. /Guide/Repair/iPod-Nano-2nd-Generation-Battery/422/all#s1808 Remove the following two screws: One #00 Phillips screw with a large head near the headphone jack. One #00 Phillips screw with a smaller head near the side of the iPod. This screw strips easily, so be sure to press down firmly on the screwdriver. /Guide/Repair/iPod-Nano-2nd-Generation-Battery/422/all#s1809 Use a metal spudger to carefully pry the headphone jack out of the casing. DO NOT remove the headphone jack from the iPod entirely, as it is connected via a fragile ribbon connector to the click wheel. /Guide/Repair/iPod-Nano-2nd-Generation-Battery/422/all#s1810 Slide the headphone jack out until the white plastic housing is no longer held in place by the metal casing. /Guide/Repair/iPod-Nano-2nd-Generation-Battery/422/all#s1811 Remove the newly-revealed Phillips #00 screw from beneath the headphone jack. /Guide/Repair/iPod-Nano-2nd-Generation-Battery/422/all#s1812 Lift the bottom bezel bracket out of the iPod. /Guide/Repair/iPod-Nano-2nd-Generation-Battery/422/all#s1813 Remove the two Phillips #00 screws from the top of the iPod. /Guide/Repair/iPod-Nano-2nd-Generation-Battery/422/all#s1814 The highlighted connector attaches the click wheel and headphone jack to the logic board. This cable must be disconnected from the logic board before continuing. /Guide/Repair/iPod-Nano-2nd-Generation-Battery/422/all#s1815 Use a spudger to disconnect the headphone jack cable from the logic board. You need to gently pry the connector toward the front of the iPod until it comes loose from the logic board. /Guide/Repair/iPod-Nano-2nd-Generation-Battery/422/all#s1816 Use a spudger to push the logic board through the iPod out of the casing. The click wheel and headphone jack should remain in the iPod. Be careful not to catch the headphone jack and click wheel on the logic board as you remove the logic board and display. /Guide/Repair/iPod-Nano-2nd-Generation-Battery/422/all#s1817 Completely remove the display and logic board from the metal casing. /Guide/Repair/iPod-Nano-2nd-Generation-Battery/422/all#s1818 Use a spudger to scrape away the black glue covering the three battery wires. /Guide/Repair/iPod-Nano-2nd-Generation-Battery/422/all#s1824 Peel up the orange tape covering the three solder points on the other side of the logic board. /Guide/Repair/iPod-Nano-2nd-Generation-Battery/422/all#s1825 Place the desoldering wick on top of the existing solder ball. Place the soldering iron on top of wick above the existing solder ball. Hold the soldering iron in place until the solder melts into the wick. Repeat the same procedure on the remaining two connectors. /Guide/Repair/iPod-Nano-2nd-Generation-Battery/422/all#s1826 Be careful not to scrape the metal rings surrounding the connectors off the logic board. If you accidentally scrape these off, you won't be able to reconnect the replacement battery. Use a metal spudger to carefully straighten the battery wires. Be sure to only touch one contact at a time. /Guide/Repair/iPod-Nano-2nd-Generation-Battery/422/all#s1827 Pull the battery wires through the logic board to free the battery. If the wires don't easily come free, make sure the wires are straight and all the solder has been removed. Slide the three wires of the replacement battery through the holes in the logic board. Going from the edge of the iPod, the order of wires is black, red, white. /Guide/Repair/iPod-Nano-2nd-Generation-Battery/422/all#s1828 Bend the wires over to prevent them from sliding out of the logic board. /Guide/Repair/iPod-Nano-2nd-Generation-Battery/422/all#s1829 Place the soldering iron onto the battery wire and metal connector for one to two seconds to heat them up. Add the solder wire and wait for the solder to melt onto the wire. Once a small bead has formed around the wire, lift the solder away first and then remove the soldering iron. Continue with the other two connections the same way, taking special care not to solder two of the connectors together. /Guide/Repair/iPod-Nano-2nd-Generation-Battery/422/all#s1830
