It fits the G41 directly, matching the OEM connector, physical dimensions, and BMS communication protocol. Capacity is drawn from product data: 4700mAh \/ 18.19Wh.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMoto G41 and XT2167 fit:\u003c\/strong\u003e\n    Both model names refer to the same hardware platform. They share the same battery bay geometry, flex connector pinout, and fuel gauge IC handshake — so one cell covers both 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 through full charge and discharge on the G41 mainboard. The BMS accepted the cell without fault codes, the charge IC stepped through trickle, CC, and CV phases correctly, and the coulomb counter registered capacity within expected tolerance.\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 for one complete discharge-charge cycle. This lets the fuel gauge IC recalibrate against the new cell's discharge curve before high-current fast charging pushes current into an uncalibrated cell — preventing early percentage jumps or premature shutdowns.\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 replacement cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a voltage cliff problem, not a capacity problem. Under modem radio or screen load, the cell voltage drops sharply below the threshold the fuel gauge IC expects at that state-of-charge. The IC reads the voltage drop as a near-empty cell and triggers a hard shutdown — even though charge remains. One full discharge-charge cycle lets the coulomb counter remap the new cell's actual voltage curve, and the shutdowns stop.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eUSB-PD fast charge not accepted on the first cycle after replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA fresh lithium-polymer cell starts with higher internal impedance than a broken-in cell. The charge IC on the G41 checks impedance and temperature before negotiating fast-charge current — if impedance reads outside its expected window, it falls back to standard 5V charging and stays there. This is normal behaviour on cycle one. Run the first full discharge-charge cycle at standard charge speed and the IC will accept fast-charge protocol on subsequent cycles once impedance settles.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43391792021594,"sku":"BWCS-MXG410SL-1","price":40.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43391792054362,"sku":"BWCS-MXG410SL-2","price":47.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43391792087130,"sku":"BWCS-MXG410SL-3","price":52.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MXG410SL-1.webp?v=1779142036","url":"https:\/\/batteryweb.com\/products\/motorola-moto-g41-replacement-battery-387v-4700mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
