It replaces OEM part numbers HZ40 and SNN5985A. Physical dimensions are 97.14 × 48.30 × 3.68mm — match these before installing.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eXT1710 variant compatibility:\u003c\/strong\u003e\n    The XT1710-08 and XT1710-11 share the same battery bay geometry, connector pinout, and BMS handshake protocol. One cell covers all listed variants without modification.\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 and discharge cycles on the Z2 Play. The BMS communicated correctly with the Snapdragon 626 power management IC, and charge termination triggered at the expected 4.35V ceiling with no errors logged.\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 map the new cell's discharge curve before high-current charging begins on 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 Z2 Play after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Z2 Play's fuel gauge IC retains the discharge curve of the original cell in its coulomb counter registers. When a new cell goes in, the IC's internal model no longer matches the actual voltage-capacity relationship of the replacement. Under load spikes — modem transmit, screen wake — the new cell's voltage drops faster than the IC expects, triggering an emergency shutdown even though the reported percentage looks safe. Run one full discharge to below 5% and a complete charge to 100% without interruption. After that cycle, the coulomb counter resets and shutdown behaviour normalises.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eTurboPower fast charging not activating after battery replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eMotorola's TurboPower protocol requires a handshake between the charge IC and the battery's BMS before high-current delivery starts. On a freshly installed cell, the BMS may reject the elevated current on the first charge cycle as a precaution against charging an unknown-state cell. Plug into the original Motorola TurboPower adapter — not a third-party charger — and let the first full charge complete at standard rate. TurboPower negotiation typically succeeds from the second cycle onward once the BMS has logged a verified full-charge event.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43392055967834,"sku":"BWCS-MXT170SL-1","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43392056000602,"sku":"BWCS-MXT170SL-2","price":28.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43392056033370,"sku":"BWCS-MXT170SL-3","price":31.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MXT170SL-1.webp?v=1779143471","url":"https:\/\/batteryweb.com\/products\/motorola-moto-z2-play-replacement-battery-38v-2800mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
