It fits the Blade Q Lux, Blade Q Lux 4G, Blade Q Lux 4G LTE, Blade D Lux LTE Dual SIM, and several additional variants sharing the same battery footprint. Dimensions are 66.60 × 50.20 × 5.30mm — confirm these match your existing cell before fitting.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBlade Q Lux family compatibility:\u003c\/strong\u003e\n    These variants share the same PCB connector layout, battery bay dimensions, and BMS handshake protocol — the fuel gauge IC on each model reads cell voltage and current through the same pin configuration, so one cell covers the range.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through full charge-discharge cycles on the Blade Q Lux platform, monitoring BMS handshake, charge IC acceptance, and voltage curve under display and modem load. The cell held a stable voltage rail throughout.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first use:\u003c\/strong\u003e\n    On first use after installation, disable fast charging and run one complete discharge-charge cycle at standard rate. This lets the fuel gauge IC map its coulomb counter against the new cell's actual discharge curve before any high-current session pushes charge into an uncalibrated state.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Blade Q Lux reports wrong battery percentage after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Blade Q Lux uses a fuel gauge IC that tracks charge state by counting coulombs against a stored discharge curve from the original cell. When you fit a new cell, that stored curve no longer matches the new cell's actual voltage-to-capacity profile. The gauge reads voltage, sees a number it associates with a different charge state on the old curve, and reports the wrong percentage. One full discharge down to automatic cutoff followed by a full charge at standard rate forces the IC to re-anchor its reference points to the new cell.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSudden shutdown at 20–30% remaining on the new cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the fuel gauge IC has not yet recalibrated and the modem or display draws a current spike the cell cannot sustain at that state of charge — voltage drops below the BMS cutoff threshold faster than the gauge predicted. The phone shuts off while still showing charge because the gauge and the real cell voltage have diverged. Run the recalibration cycle described above: discharge fully to automatic shutdown, then charge uninterrupted to 100% at standard rate. After one complete cycle the gauge anchors correctly and the shutdowns stop.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43392107708506,"sku":"BWCS-ZTA430SL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43392107741274,"sku":"BWCS-ZTA430SL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43392107774042,"sku":"BWCS-ZTA430SL-3","price":29.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ZTA430SL-1.webp?v=1779143816","url":"https:\/\/batteryweb.com\/products\/zte-blade-q-lux-replacement-battery-38v-2300mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
