Replacement Battery for Microsoft Zune 80gb 120gb 2nd Gen 850mAH Repair Part (Battery ONLY no Tool)

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!

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.

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!

I received my product on time and was set right place. Thank-you to the driver. Packaging was decent, box was closed properly with padding. The item came intact and was the right item which is important. UPDATE: 2/13/26 Battery was installed, all points correctly soldered. I put the zune back together, and it said low battery and the indicator was red. It wouldn't charge, the board is fine it read all the music, movies, ect. I had it plugged in for 24 hrs. and it wouldn't charge. I picked it up this morning while still charging and it was dead.

Okay, so I wanted one of these but the reviews were bad. I love my Zune, so I took a chance and I thought I got bit, the battery would t hold a charge, it would charge up til the battery icon was green, and then it would die in about three hours and I thought I was boned but I asked around on reddit, all the “experts” on there, and it turns out you need to “calibrate” your battery! What you do is play a video or summat, and let it die completely. Then charge it up. The battery lasts a few days for me now. So don’t be deterred by the bad reviews like I almost was, calibrate your battery and you’ll be off to the races!

Pried the case open, which is a bit of a trial in and of itself, soldered in the new battery. All I can say so far is, at least the old one held just enough charge to power on for 2-3 seconds. All I get now is an extremely faint charging symbol. Got the new battery in, left it on the charger for 24 hours (yes, I've checked the charger, it works fine on my other Zune). Tried to power on, no dice. Did some research, found a few people had issues where they had to swap the white and blue wires (I'm assuming, thermistor and some other sensor), so I tried that as well. 24 hours charging later, still nothing but the faint charging icon. On the one hand, I've sent in for a replacement. However, this requires sending it back "in its original packaging" (which, for the record, was a small, white cardstock box with no markings) and waiting almost a week for the replacement. Nearly a week to get here, three days of testing to find out it doesn't charge, and now nearly another week, hopefully one that works this time. Maybe I'll look into some kind of alternate power source if it fails, too. [Edit:] Second battery, same problems.

I just installed one in my Zune 120gb and I'm beyond thrilled to say that the hardest work really was just opening the case. (Hint: There's clips inside the top half of the case's plate, more often than you'd think. This thing is designed like a TANK.) The battery needs to be hot-swapped, but it's cheap to get a soldering tool and solder. I took off the old battery and soldered in the new one- black, red, white, and blue cords. Immediately, my Zune started to charge. ALL HAIL THIS VENDOR. They made the difference between trash and a functional device by providing me with this battery. The relief is REAL.

Me put wire on board. me break zune me don't know if wire fault or me fault
