## Description

High quality replacement repairt rechargeable battery for Zune 80GB 120GB models. Even higher capacity than original version which is 650mAH, this version is 850mAH. Battery will compatible with Microsoft Zune 80gb 120gb 2nd Gen

Review: Works great and was perfect for my 120 GB Zune - I am so grateful to have found this! It totally fixed my non-working Zune player that had previously worked a couple of years ago! So glad to have it working again!
Review: Brought new life into my Zune - This new battery was what my Zune needed to be brought back to life. The install was not exactly enjoyable as getting the casing apart was rough and, unlike pretty much every other device, this battery is soldered in. If you have access to a soldering iron and some experience with it, this install isn't very hard, even for a beginner. How I knew I needed a new battery (for anybody else wondering): When I tried to charge the Zune, a faint image of a battery with a lightning bolt would show, but even after leaving the device charging for a full day, it still would not turn on.

## Questions & Answers

**Q: I bought this and just put it in. It has been on the charger for3 hours but hasn't lit up or anything? Did I get a bad battery?**
A: I found this remedy on one of the old Zune Repair sites "When your Zune has been dead for a time and will not charge at all. (Black screen with no battery icon) Sit with it in your lap and plug it in for 20 seconds then disconnect for 20 seconds. repeat several times and your device will begin to charge after several connect/disconnect cycles. Reason: The battery needs a small charge to initiate the charging circuit in the zune. When the battery is completely dead, there is no charge to start charging. When you first plug it in, a small burst of charge gets through before the circuit disables the charge as a protection. (It associates no internal voltage as a bad or missing battery.) So, connecting and disconnecting repeatedly will charge the battery very slightly each time, eventually retaining enough charge to allow the circuit to begin a standard charge."  Worked for me when I tried it with new dead battery.

**Q: How difficult is it ro change the battery?**
A: It can be difficult if you do not know how to solder wires. Opening the case car was easier than expected.

**Q: I have a zune 120gb. how do i know if it is 2nd gen.? says model 1376 on back.**
A: The 120GB was a second generation model. First generation Zunes were 30GB.

**Q: What type battery for 30gb zune?**
A: I’ve purchased this for Zune 80GB second gen, perfect  Replacement. I believe the 120GB version uses the same as de 80GB.
Not sure for the 30GB

I am so grateful to have found this! It totally fixed my non-working Zune player that had previously worked a couple of years ago! So glad to have it working again!

### ⭐⭐⭐⭐⭐ Brought new life into my Zune
*by C***R on September 29, 2021*

This new battery was what my Zune needed to be brought back to life. The install was not exactly enjoyable as getting the casing apart was rough and, unlike pretty much every other device, this battery is soldered in. If you have access to a soldering iron and some experience with it, this install isn't very hard, even for a beginner.

### ⭐⭐⭐⭐⭐ Great replacement battery!
*by W***R on July 20, 2022*

Got the battery and followed the instruction to install the battery. Wasn't too bad. The most difficult part was taking the back case off of the Zune. Once I got it all put back together, I charged the battery it wasn't charging or holding charge at all. When I contacted the support, the staff told me to discharge and fully re-charge about three times. After doing that three times, the battery charges fully and lasts about 30 hours!!! Great replacement battery!
