It fits XT1650-03 and XT1650-05 variants and slots into the same footprint as the original at 75.83 × 65.45 × 3.80mm. Voltage and connector pinout match OEM spec — no modifications needed.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eXT1650 platform compatibility:\u003c\/strong\u003e\n    The XT1650-03 and XT1650-05 share the same battery bay dimensions, BMS handshake protocol, and 3.8V nominal voltage rail. One cell covers both variants without any electrical compromise.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell in an XT1650-03 unit and confirmed the BMS accepted the cell, completed charge termination cleanly at 4.35V, and held voltage above 3.6V through a full processor and modem load sequence.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first use:\u003c\/strong\u003e\n    After installation, disable fast charging and run one full discharge-to-charge cycle. This lets the fuel gauge IC map the new cell's discharge curve before Motorola's TurboPower protocol pushes high current into an uncalibrated cell.\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 Z after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe XT1650 fuel gauge IC stores a learned discharge curve from the old cell. When a new cell goes in, the IC applies the old curve to the new cell's chemistry — and misjudges the voltage cliff. The phone reads 25% but the cell has already dropped below the modem's minimum sustain voltage under load, triggering an emergency shutdown. One complete discharge cycle — draining to auto-shutdown, then charging uninterrupted to 100% — forces the coulomb counter to reset against the new cell's actual capacity. After that cycle, percentage readings stabilise and premature shutdowns stop.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eTurboPower fast charge not activating after replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eMotorola's TurboPower protocol requires the charge IC to confirm cell impedance is within an acceptable range before switching from 5W to high-current mode. A brand-new cell has higher internal impedance than a broken-in cell, so the charge IC defaults to standard 5W on the first cycle. This is not a fault — it is a protective handshake. Run one full standard charge cycle and TurboPower will engage normally on subsequent charges once the cell's impedance settles below the IC's threshold, typically around 100–150mΩ.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43392084639834,"sku":"BWCS-MXT165SL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43392084672602,"sku":"BWCS-MXT165SL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43392084705370,"sku":"BWCS-MXT165SL-3","price":29.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MXT165SL-1.webp?v=1779143707","url":"https:\/\/batteryweb.com\/products\/motorola-moto-z-td-lte-replacement-battery-38v-2300mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
