It replaces OEM part Li3712T42P3h475248 when the original cell degrades, swells, or no longer holds a usable charge. Voltage and physical footprint match the stock battery — 51 x 46 x 5mm.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCross-model fit — Crescen, Atlas, Blade II:\u003c\/strong\u003e\n    These ZTE handsets share the same battery bay dimensions, 3.7V nominal voltage rail, and connector pinout, which is why a single cell covers all four model variants without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell under a simulated modem and screen load. The BMS held voltage above the cutoff floor through a full discharge and accepted charge current from the first cycle without tripping an over-current fault.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first install:\u003c\/strong\u003e\n    On first use after fitting this cell, run one complete discharge down to auto-shutdown, then charge uninterrupted to 100% before resuming normal use. This lets the phone's coulomb counter relearn the new cell's actual discharge curve and prevents erratic percentage readings.\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 Crescen after a cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA new Li-ion cell has a slightly different internal resistance profile than the aged cell it replaces. When the Crescen's modem fires up for a call or the screen peaks brightness, the load spike pulls voltage down faster than the fuel gauge IC expects. The phone reads that voltage drop as empty and cuts power — even though the capacity gauge still shows 20–30%. One full discharge-charge cycle recalibrates the fuel gauge against the new cell's actual curve, and the premature shutdowns stop.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePhone won't power on after sitting in storage for several months\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge in storage. If voltage drops below approximately 2.5V, the battery's BMS enters a protective lockout state and refuses to supply current — so the phone appears completely dead. Connect the phone to a wall charger, not a USB port, and leave it for 20–30 minutes without attempting to power it on. Once the charge IC pushes the cell above the BMS recovery threshold, the phone will respond and boot normally. If the charge LED never illuminates after 45 minutes, the cell has dropped below the recovery floor and needs replacing.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43405045497946,"sku":"BWCS-ZTP736SL-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43405045530714,"sku":"BWCS-ZTP736SL-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43405045563482,"sku":"BWCS-ZTP736SL-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ZTP736SL-1.webp?v=1779369898","url":"https:\/\/batteryweb.com\/products\/zte-crescen-replacement-battery-37v-1100mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
