3. Setup and Installation

Tools Required (Not Included):

• Small Phillips head screwdriver
• Plastic prying tools (spudgers) or thin metal opening tools
• Soldering iron and fine-gauge solder
• Desoldering wick or pump
• Tweezers (optional, for handling small wires)
• Safety glasses

Installation Steps:

1. Power Off Device: Ensure your Microsoft Zune is completely powered off before beginning.
2. Disassemble Zune Casing: Carefully open the Zune casing. This is often the most challenging step due to tight clips and adhesive. Use plastic prying tools to gently separate the front and back panels. Refer to online guides or videos specific to Zune 80GB/120GB 2nd Gen disassembly for detailed instructions.
3. Locate and Disconnect Old Battery: Once the casing is open, locate the existing battery. Note how the wires are connected to the Zune's circuit board. The original battery is typically soldered in place.
4. Desolder Old Battery: Using a soldering iron and desoldering wick/pump, carefully desolder the wires of the old battery from the circuit board. Pay attention to the color and position of each wire (typically red for positive, black for negative, and white/blue for thermistor/data).
5. Remove Old Battery: Gently remove the old battery from its compartment. It may be secured with light adhesive.
6. Prepare New Battery: The new WirelessFinest battery comes with pre-attached wires. Ensure the wire ends are tinned (coated with a thin layer of solder) if necessary.
7. Solder New Battery: Carefully solder the new battery's wires to the corresponding pads on the Zune's circuit board. Match the wire colors exactly as they were on the old battery. Common wire colors are:
   • Red: Positive (+)
   • Black: Negative (-)
   • White/Blue: Thermistor/Data (ensure these are correctly matched, as incorrect connection can prevent charging or proper operation).

   Ensure strong, clean solder joints. Avoid bridging connections.

8. Secure New Battery: Place the new battery into the Zune's battery compartment. You may use a small piece of double-sided adhesive to secure it if needed.
9. Reassemble Zune Casing: Carefully reassemble the Zune casing, ensuring all clips align and close properly. Do not force the casing if it resists.

4. Operating Instructions

Initial Charging and Calibration:

After installation, it is crucial to calibrate the new battery for optimal performance and accurate battery level reporting. Follow these steps:

1. Full Discharge: Use your Zune until the battery is completely depleted and the device powers off automatically. This may involve playing music or videos continuously.
2. Full Charge: Connect your Zune to a power source and charge it uninterrupted until it reaches 100% capacity.
3. Repeat: Repeat the full discharge and full charge cycle two more times (total of three cycles). This process helps the battery management system accurately learn the new battery's full capacity.

After calibration, your battery should provide accurate readings and optimal runtime.

5. Maintenance

To prolong the life of your WirelessFinest replacement battery:

• Avoid Extreme Temperatures: Do not expose your Zune to very high or very low temperatures, as this can degrade battery performance and lifespan.
• Regular Usage: Use your Zune regularly. Long periods of inactivity can affect battery health.
• Partial Discharges: For daily use, partial discharges and charges are generally fine. Full discharge cycles (as described in calibration) are only needed periodically or if battery readings become inaccurate.
• Proper Storage: If storing the Zune for an extended period, charge the battery to about 50% before storage.

6. Troubleshooting

If you encounter issues after installing the new battery, consider the following:

• Battery Not Charging / Holding Charge:
  • Calibration: Ensure you have completed the initial battery calibration process (Section 4).
  • Solder Connections: Re-check all solder joints for the battery wires. Ensure they are solid and there are no cold joints or bridges.
  • Wire Polarity: Double-check that the red and black wires are connected to the correct positive and negative terminals.
  • Thermistor/Data Wires: Verify the white and blue wires (if present) are connected correctly. Some users have reported issues resolved by swapping these two specific wires if the battery is not recognized or charging. Proceed with caution and only if other steps fail.
  • Charging Source: Ensure your Zune charger and cable are functional.
• Zune Not Powering On:
  • Battery Connection: Confirm the battery is securely connected and soldered.
  • Other Internal Connections: Ensure all other internal connectors (e.g., screen, hard drive) were reconnected properly during reassembly.
  • Charge Level: Connect the Zune to a charger for at least 30 minutes to ensure there's enough initial charge.
• Device Overheating: Immediately disconnect power and cease use. This could indicate a short circuit or a faulty battery. Review all connections and ensure no wires are pinched or exposed.
