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!

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 ## Customer Reviews ### ⭐⭐⭐⭐⭐ Gotta calibrate the thing! *by D***N on August 5, 2025* Okay, so I wanted one of these but the reviews were bad.

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. 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. ## Frequently Bought Together - WirelessFinest Replacement Battery for Microsoft Zune 80gb 120gb 2nd Gen 850mAH Repair Part (Battery ONLY no Tool) - USB Sync Data Transfer Charger Power Cable Cord for Microsoft ZUNE 80 ZUNE 120 ZUNE 4 ZUNE 8 ZUNE 16 ZUNE 30GB 4GB 8GB 80GB 120GB ZUNE HD 16GB 32GB 64GB - KingSpec Yansen 128GB 1.8" ZIF 40pin SSD Solid State Disk SM2236 Controller Compatible with Compact PC, Old Laptop and Media Player --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.gr/products/149419509-850mah-battery-for-microsoft-zune-80gb-120gb-2nd-gen](https://www.desertcart.gr/products/149419509-850mah-battery-for-microsoft-zune-80gb-120gb-2nd-gen) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-10-29*
