It fits the headset's compact 30 x 20 x 4mm battery bay and restores wireless audio and DECT radio function when the original cell has degraded. Capacity is 180mAh (0.67Wh), matching the OEM specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eLifeChat ZX-6000 fit:\u003c\/strong\u003e\n    The ZX-6000 uses a single Li-Polymer cell at 3.7V nominal to power both the audio driver and the DECT radio simultaneously. Any replacement must match this voltage exactly — feeding a higher-voltage cell trips the headset's onboard protection circuit and prevents pairing with the base station.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge and discharge cycles on the ZX-6000 platform, confirming the BMS accepted the pack without a charging fault. The protection circuit engaged correctly at low-voltage cutoff and released cleanly on re-seat in the base station.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle base station conditioning:\u003c\/strong\u003e\n    Place the headset in the base station and allow a complete uninterrupted charge cycle before your first call. The ZX-6000 base logs the new cell during this cycle — skipping it causes the talk-time indicator to read inaccurately for several sessions.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the ZX-6000 cuts out mid-call on a new battery\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe ZX-6000 draws current from one small cell to run both the speaker and the DECT radio at the same time. On a cell that has not completed its first full charge cycle, internal resistance is still elevated — combined audio and radio draw creates a brief voltage sag that the BMS reads as low-battery cutoff. The headset then drops the call and returns to the base. A full conditioning cycle in the base station before first use reduces internal resistance enough that the cell handles the combined draw without sagging below the cutoff threshold.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBase station showing full charge but headset shuts off after a few minutes\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA new Li-Polymer cell ships at storage voltage — typically around 3.6V — not at full charge. If the base station reads this as a full pack and stops charging early, the headset starts each session with less capacity than indicated. The fix is to let the headset sit in the base for a full uninterrupted charge cycle of at least 3 hours without removing it. After that cycle, the cell voltage should reach approximately 4.2V and the base station talk-time estimate will stabilise.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428159225946,"sku":"BWCS-ZX6000SL-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428159258714,"sku":"BWCS-ZX6000SL-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428159291482,"sku":"BWCS-ZX6000SL-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ZX6000SL_1.webp?v=1779934292","url":"https:\/\/batteryweb.com\/products\/microsoft-lifechat-zx-6000-replacement-battery-37v-180mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
