Before opening your iPod, ensure that the hold switch is in the locked position. /Guide/Repair/iPod-Nano-1st-Generation-Battery-Replacement/774/all#s1860 The rear panel is secured to the front case by eleven clips permanently attached to the rear panel. These clips lock onto small tabs machined into the front case. To free the tabs, they must be pushed toward the center of the iPod. Note the location of all tabs on the rear panel. When using an iPod opening tool to free the rear panel, be sure to work the tool at the location of these clips. /Guide/Repair/iPod-Nano-1st-Generation-Battery-Replacement/774/all#s4430 Opening the iPod can be challenging. Don't get discouraged if it takes you a few tries before the iPod is opened. Insert the large iPod opening tool into the seam between the front case and rear panel of the iPod, below the dock connector. Run the tool back and forth to create an opening. The tool's edge should point toward the rear panel to prevent any accidental scratching of the aluminum front case. /Guide/Repair/iPod-Nano-1st-Generation-Battery-Replacement/774/all#s1861 Opening the iPod can be challenging.

Gently enlarge the existing gap by pressing/wiggling the small iPod opening tool into the gap near each of the the two tabs attached to the rear case, pushing the clips toward the center of the iPod until both have been freed. /Guide/Repair/iPod-Nano-1st-Generation-Battery-Replacement/774/all#s4431 Repeat the same procedure listed in the previous step to free the five clips along the headphone jack side of the iPod. /Guide/Repair/iPod-Nano-1st-Generation-Battery-Replacement/774/all#s1863 Repeat the same procedure listed in the previous step to free the five clips along the headphone jack side of the iPod. /Guide/Repair/iPod-Nano-1st-Generation-Battery-Replacement/774/all#s1863 Repeat the same procedure listed in the previous step to free the five clips along the headphone jack side of the iPod. /Guide/Repair/iPod-Nano-1st-Generation-Battery-Replacement/774/all#s1863 After ensuring all tabs are free, separate the two halves of the iPod. The rear panel is now free from the iPod. /Guide/Repair/iPod-Nano-1st-Generation-Battery-Replacement/774/all#s1865 Remove any kapton tape over the screws, if necessary. Remove the following 3 screws: Two 3 mm Phillips screws near the dock connector. One 4 mm Phillips screw along the edge of the logic board. /Guide/Repair/iPod-Nano-1st-Generation-Battery-Replacement/774/all#s1866 Peel up the ground strap connecting the battery to the logic board. /Guide/Repair/iPod-Nano-1st-Generation-Battery-Replacement/774/all#s1867 Insert the flat end of a spudger between the battery and the headphone jack side of the front case to pry the battery up off the adhesive securing it to the front case. Rotate the battery out of the iPod and lay it next to the iPod. The battery is still soldered to the logic board by three wires, so don't remove it entirely. /Guide/Repair/iPod-Nano-1st-Generation-Battery-Replacement/774/all#s1868 Insert the flat end of a spudger between the battery and the headphone jack side of the front case to pry the battery up off the adhesive securing it to the front case.

The battery is still soldered to the logic board by three wires, so don't remove it entirely. /Guide/Repair/iPod-Nano-1st-Generation-Battery-Replacement/774/all#s1868 Gently lift up on the dock connector end of the logic board to ensure the logic board is free. /Guide/Repair/iPod-Nano-1st-Generation-Battery-Replacement/774/all#s1869 Grasp the end of the logic board near the battery connector with one hand, and hold onto the rest of the iPod with your other hand. Make sure the logic board is lifted slightly above the white plastic notch on the battery side of the board. This notch prevents the board from sliding out in the next step. Slide the logic board out of its holding brackets on the rear of the display. The logic board is still connected to the iPod by two ribbon cables. /Guide/Repair/iPod-Nano-1st-Generation-Battery-Replacement/774/all#s1870 Disconnecting the following two ribbon cables may be challenging. To prevent straining the cables or connectors, you can only separate the two halves of the iPod about 1/2 inch during the process. Use a spudger to flip up the black plastic tab holding the orange display ribbon in place. The black tab will rotate up 90 degrees, releasing the ribbon cable. /Guide/Repair/iPod-Nano-1st-Generation-Battery-Replacement/774/all#s1871 Use a spudger to slide the display ribbon out of its connector. /Guide/Repair/iPod-Nano-1st-Generation-Battery-Replacement/774/all#s1872 Use a spudger to flip up the black plastic tab holding the orange click wheel ribbon in place.

The ends of the battery leads are fed through small holes in the logic board and held in place by a small amount of solder. Begin by heating the exposed end of the white battery lead with the tip of a soldering iron while simultaneously pulling the lead away from the connection, using tweezers to grasp the lead by the insulation. De-solder the remaining leads, following the procedure illustrated above. Due to the delicate nature of electronic components, it is imperative to limit the amount of heat transferred from the soldering iron to the logic board. An easy way to accomplish this is to pull on the battery lead with light, continuous tension, while the soldering iron heats up the connection. In order to avoid damage, lift the solder tip off the connection as soon as the solder melts and the lead slides out. /Guide/Repair/iPod-Nano-1st-Generation-Battery-Replacement/774/all#s4612 The next few steps require a soldering iron.

This way, you can insert the new battery leads and solder them in place. To open the solder holes, open a safety pin and push it against the solder blocking the hole. At the same time, heat the same solder pad from the other side of the logic board. Opening the holes completely will require repeating this procedure several times from alternating sides of the logic board. These holes are extremely small, so the safety pin will probably be too large to pass all the way through. Do not insert the entire pin through the hole -- only the tip of the pin. /Guide/Repair/iPod-Nano-1st-Generation-Battery-Replacement/774/all#s4609 To aid in soldering the new battery, be sure the solder pad holes are clear of solder.

Using a pair of tweezers, insert the stripped ends of the battery leads into their respective holes. Insert the black lead into the hole nearest the hold switch (shown in red). Insert the red lead into the center hole. Insert the white lead into the hole furthest from the hold switch. To keep the leads in place, it may be helpful to first bend them 90 degrees, and then insert them into the holes. /Guide/Repair/iPod-Nano-1st-Generation-Battery-Replacement/774/all#s4439 Flip the logic board and battery over so the bare ends of the battery leads are facing up. /Guide/Repair/iPod-Nano-1st-Generation-Battery-Replacement/774/all#s4440 In this step, you will solder the battery leads to the solder pads on the logic board. Excess heat transferred to the logic board while soldering may result in electronic component damage. As a rule of thumb, hold the tip of the soldering iron against the joint just long enough to melt the solder, then quickly remove it. Solder the connection by momentarily placing the tip of the soldering iron against the connection, melting solder into the connection, and quickly removing both the solder and the tip of the soldering iron from the connection. The solder should flow around the new battery lead, solidly connecting it to the pad on the logic board. Solder the other two battery leads in the same fashion, taking care not to bridge any of the connections together. /Guide/Repair/iPod-Nano-1st-Generation-Battery-Replacement/774/all#s4441 In this step, you will solder the battery leads to the solder pads on the logic board.
