It fits models PAH30004, PAH30004US, and XT2041-7. The KZ50 cell slots directly into the battery bay and connects to the same BMS handshake points as the original.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMoto G Power model coverage:\u003c\/strong\u003e\n    PAH30004, PAH30004US, and XT2041-7 all share the same battery bay dimensions, connector pinout, and fuel gauge IC communication protocol — one cell fits all three without adapter or modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell on a Moto G Power unit and confirmed the BMS handshake completed on first boot, charge current ramped correctly through CC\/CV stages, and the fuel gauge IC accepted the cell without throwing a battery-health error.\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 full discharge-charge cycle at standard rate. This lets the fuel gauge IC map the new cell's discharge curve before high-current fast charging pushes load into an uncalibrated coulomb counter.\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 Moto G Power after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Moto G Power's fuel gauge IC was calibrated against the original cell's voltage-discharge curve. A new KZ50 cell has a slightly different impedance profile, so the IC miscalculates remaining capacity at low state-of-charge. When the display and modem draw peaks — scroll, call, or data burst — the cell voltage drops below the BMS cutoff threshold even though the OS still shows 20–30%. One full discharge-charge cycle at standard rate lets the coulomb counter relearn the curve and pushes the cutoff point back to where it belongs.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eUSB-PD fast charge not activating on the first cycle after replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eAfter a cell swap, the charge IC sometimes defaults to slow-charge mode on the first cycle because the BMS has not yet validated the new cell's internal resistance against its fast-charge admission threshold. This is not a fault in the cable or adapter. Complete one full standard-rate charge to 100% before enabling fast charging again. After that cycle, fast charge should negotiate normally — if it still does not, check the charge port for debris before assuming a BMS fault.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43391981813850,"sku":"BWCS-MXT417SL-1","price":29.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43391981846618,"sku":"BWCS-MXT417SL-2","price":33.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43391981879386,"sku":"BWCS-MXT417SL-3","price":36.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MXT417SL-1.webp?v=1779142720","url":"https:\/\/batteryweb.com\/products\/motorola-moto-g-power-replacement-battery-385v-4900mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
