It fits the same connector and physical footprint as the factory unit. Voltage matches the 3.85V nominal rail the Pixel 2 XL power management IC expects.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePixel 2 XL \/ G011C fitment:\u003c\/strong\u003e\n    The Pixel 2 XL 6.0 and G011C share the same battery bay dimensions, connector pinout, and BMS handshake requirements — all covered by this cell. The EAC63718201 cross-reference confirms LG-sourced OEM compatibility across both regional variants.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell on a Pixel 2 XL through charge, full discharge, and fast-charge re-entry. The BMS accepted USB-PD negotiation without rejection on the second cycle, and thermal output during charge stayed within expected bounds for a new high-impedance cell.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first cycle:\u003c\/strong\u003e\n    On first use after installation, disable fast charging and run one complete discharge-charge cycle at standard rate. The Pixel 2 XL fuel gauge IC calibrates its coulomb counter against the cell's discharge curve — doing this before fast charging prevents the IC from pushing 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\"\u003eWhy the Pixel 2 XL reports wrong battery percentage after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Pixel 2 XL uses a coulomb-counting fuel gauge IC that builds its charge model from the previous cell's history. After swapping to a new BL-T35 cell, the IC still references the old discharge curve — so the percentage it displays can lag or jump until it relearns. The fix is one full discharge cycle from 100% down to automatic shutdown, followed by a full charge with the screen off. After that single cycle, the gauge aligns to the new cell and percentage accuracy stabilises.\u003c\/p\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 happens when the fuel gauge IC hasn't yet mapped the new cell's voltage cliff — the point where voltage drops sharply under modem or display load. The device shuts down to protect the power rail even though the reported percentage looks safe. Charge the phone fully to 100%, then let it drain in normal use without topping it up early. Once the IC records a complete discharge curve, the cutoff point recalibrates and shutdowns at 20–30% stop occurring.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43392021200986,"sku":"BWCS-GPW230SL-1","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43392021233754,"sku":"BWCS-GPW230SL-2","price":29.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43392021266522,"sku":"BWCS-GPW230SL-3","price":32.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-GPW230SL-1.webp?v=1779142943","url":"https:\/\/batteryweb.com\/products\/google-pixel-2-xl-2018-replacement-battery-385v-3500mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
