It matches the OEM part number Li3710T42P3h553457-NTC and fits the original battery bay without modification. Voltage and capacity figures are sourced directly from the product specification — 3.7V nominal, 4.07Wh.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eChorus and D930 compatibility:\u003c\/strong\u003e\n    Both models share the same battery bay dimensions (54.50 × 33.50 × 5.50mm), connector pinout, and BMS handshake protocol — one cell covers both.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through the ZTE charge IC and confirmed the BMS communicates correctly at full charge termination. Charge current tapered cleanly at the top-of-charge threshold with no false cutoff.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first cycle:\u003c\/strong\u003e\n    After fitting the new cell, run one complete discharge down to automatic shutdown, then charge uninterrupted to 100% before re-enabling any fast-charge setting. This gives the coulomb counter a full reference cycle against the new cell's discharge curve.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSudden shutdown at 20–30% on the ZTE Chorus after a cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a voltage cliff problem, not a capacity problem. Under peak load — mobile data radio transmitting or screen at full brightness — the new cell's internal resistance causes a brief voltage sag. If that sag pulls the cell below the BMS low-voltage cutoff threshold, the phone shuts off even though the fuel gauge still shows charge remaining. One full reference cycle resets the coulomb counter and shifts the shutdown point to match the actual cell curve. After calibration, the OS reported percentage aligns with real remaining capacity.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePhone won't power on after the replacement battery sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge during storage. If a replacement cell drops below approximately 2.5V per cell, the BMS enters lockout mode and blocks charge input to prevent damage. The phone appears completely dead — no boot logo, no charging indicator. Connect the phone to a wall charger (not a PC USB port) and leave it for 15–20 minutes without pressing the power button. The charge IC trickle-charges the cell out of lockout; once the cell recovers to around 3.0V, the BMS re-enables normal charging and the phone will power on.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43405042122842,"sku":"BWCS-ZTD930SL-1","price":28.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43405042155610,"sku":"BWCS-ZTD930SL-2","price":32.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43405042188378,"sku":"BWCS-ZTD930SL-3","price":34.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ZTD930SL-1.webp?v=1779369859","url":"https:\/\/batteryweb.com\/products\/zte-chorus-replacement-battery-37v-1100mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
