It matches OEM part numbers G011B, G011B-B, and 35H00273-00M. If your phone shuts down unexpectedly, refuses to charge past a certain percentage, or no longer holds charge through a normal day, this cell addresses the degraded original.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePixel 2 XL and Pixel 4a platform fit:\u003c\/strong\u003e\n    Both devices share the G011B cell specification — same voltage rail, same physical footprint (76.30 × 63.00 × 4.40mm), and compatible BMS communication with the PMIC on each board. One cell part number covers both handsets.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through charge and discharge on a Pixel 4a motherboard. The BMS accepted the cell without error flags, charge termination triggered correctly at 4.35V, and the fuel gauge IC tracked state-of-charge through the full curve without dropout events.\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. The fuel gauge IC on these Pixel devices calibrates its coulomb counter against the cell's actual discharge curve. Running a slow cycle first gives the IC clean data before high-current charging pushes current into an uncalibrated model.\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 Pixel 4a after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the fuel gauge IC is still running a discharge model calibrated to the old, degraded cell. The new cell has a steeper voltage cliff under modem and display load than the IC expects at that state-of-charge. The phone reads 25% remaining but the cell voltage drops below the safe cutoff threshold under load — and the PMIC shuts the device down. One full slow discharge-charge cycle forces the coulomb counter to rebuild its model against the new cell's actual curve and eliminates the premature cutoff.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eUSB-PD fast charging not negotiating after replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eOn first connection after a cell swap, the charge IC may not negotiate the full USB-PD contract with the charger. The BMS on a freshly installed cell reports a low state-of-charge that can cause the charge controller to default to standard 5V\/0.9A input until the cell reaches a minimum threshold voltage — typically around 3.6V. Plug in the original Google 18W charger rather than a third-party adapter for the first charge. Once the cell clears that threshold, the USB-PD handshake completes normally and full charge rates resume.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43392053968986,"sku":"BWCS-GPW200SL-1","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43392054001754,"sku":"BWCS-GPW200SL-2","price":29.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43392054034522,"sku":"BWCS-GPW200SL-3","price":32.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-GPW200SL-1.webp?v=1779143471","url":"https:\/\/batteryweb.com\/products\/google-g011c-replacement-battery-385v-3800mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
