It fits the XT2163-4 and XT2163DL variants and uses the OEM part number NT40. It restores power to a phone that no longer holds charge or fails to turn on due to a degraded cell.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eXT2163-4 and XT2163DL fit confirmation:\u003c\/strong\u003e\n    Both variants share the same battery bay dimensions, connector pinout, and BMS handshake protocol. The NT40 cell fits both without modification — no adapter, no rewiring.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell on the Moto G Pure platform and confirmed the BMS accepted the charge curve without triggering overvoltage cutoff. The fuel gauge IC initialised correctly after one full discharge-charge cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration after install:\u003c\/strong\u003e\n    On first use after fitting this cell, disable fast charging and run one complete discharge down to automatic shutdown, then charge to 100% on standard charge. This lets the fuel gauge IC map the new cell's discharge curve before fast charge pushes high current 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\"\u003eSudden shutdown at 20–30% on the Moto G Pure after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens because the fuel gauge IC is still running the discharge curve from the old, degraded cell. When the new cell hits a voltage point the IC doesn't recognise as low, it can misreport remaining capacity by 20–30%. Under modem or display load, the cell voltage drops sharply at that point and the phone shuts down as a protection response. One full discharge-charge cycle on standard charging — no fast charge — resets the coulomb counter and aligns the IC to the new cell's actual voltage floor.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eUSB fast charge not activating on the first cycle after fitting the NT40\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Moto G Pure's charge IC runs a handshake with the battery BMS before allowing fast charge current. On the first cycle after fitting a new cell, the BMS may not complete that handshake until it has seen at least one full charge cycle at standard rate. If fast charging is not triggering, plug into a standard 5V charger and allow a full charge to 100%. After that cycle completes, the BMS handshake resolves and fast charge should activate on the next session.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43391876464730,"sku":"BWCS-MXT216SL-1","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43391876497498,"sku":"BWCS-MXT216SL-2","price":30.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43391876530266,"sku":"BWCS-MXT216SL-3","price":33.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MXT216SL-1.webp?v=1779142479","url":"https:\/\/batteryweb.com\/products\/motorola-moto-g-pure-replacement-battery-385v-3650mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
