It replaces OEM part numbers Li3710T42P3h553457, li3714T42P3h-653457, and Li3709T72P3H553447. Physical dimensions are 54.54 × 33.69 × 5.26mm — confirm these against your original cell before ordering.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMulti-model ZTE platform fit:\u003c\/strong\u003e\n    The N600, U260, F100, and T6 share the same battery bay geometry and voltage rail. One cell revision covers the group because ZTE standardised the connector pinout and BMS handshake logic across this mid-2000s platform series.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through full charge and discharge on compatible ZTE hardware. The BMS accepted charge current normally, reported voltage accurately at the protection IC, and tripped the low-voltage cutoff at the expected threshold without any spurious lockout events.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first cycle:\u003c\/strong\u003e\n    After installing this cell, run one complete discharge down to auto-shutoff, then charge uninterrupted to 100% before normal use. The ZTE fuel gauge IC recalibrates its coulomb counter against the new cell's actual discharge curve during this cycle — skipping it causes inaccurate percentage readings from day one.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the N600 reports wrong battery percentage after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe ZTE N600 uses a simple fuel gauge IC that tracks charge state by counting current in and out of the cell — a coulomb counter. When you swap in a new cell, the counter still holds the old cell's reference curve. The IC has no way to know the new cell's actual capacity until it observes a full cycle. Until that cycle completes, the percentage displayed is mapped against the wrong baseline, so readings can read high early and drop abruptly near 20–30%. One full discharge-to-shutoff followed by a full uninterrupted charge resets the reference and stabilises percentage reporting.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSudden shutdown at 20–30% remaining on the replacement cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a voltage cliff, not a capacity problem. When the modem transmits or the screen backlight spikes, current draw pulls the cell voltage down faster than the fuel gauge IC expects. If the IC's reference curve is still calibrated to the old degraded cell, it underestimates how close the new cell is to the BMS low-voltage cutoff — typically 3.0V on this platform. The phone shuts down to protect the cell even though the displayed percentage looks safe. Run the recalibration cycle described above; after one full cycle the IC maps shutdown correctly to the new cell's actual voltage curve.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43405081411674,"sku":"BWCS-ZTX850SL-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43405081444442,"sku":"BWCS-ZTX850SL-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43405081477210,"sku":"BWCS-ZTX850SL-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ZTX850SL-1.webp?v=1779369935","url":"https:\/\/batteryweb.com\/products\/zte-n600-replacement-battery-37v-800mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
