It fits the original battery slot and restores power capacity lost to cell degradation. OEM part numbers covered include 35H00123-00M, 35H00123-02M, 35H00123-03M, 35H00123-22M, RHOD160, BA S390, and BA S420.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePixel 2 G8 compatibility:\u003c\/strong\u003e\n    All listed OEM part numbers share the same 3.7V rail, physical footprint (65.00 × 43.28mm), and connector pinout. The BMS handshake protocol is consistent across the G8 revision range, so the fuel gauge IC on the Pixel 2 mainboard communicates with this cell without modification.\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 2 unit. The BMS held charge cutoff at 4.2V and triggered low-voltage protection cleanly below 3.0V with no false-trip events under screen and modem load.\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 full discharge-charge cycle at standard rate. This lets the Pixel 2 fuel gauge IC map the new cell's discharge curve before the coulomb counter begins tracking state-of-charge accurately.\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 reports wrong battery percentage after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Pixel 2 uses a fuel gauge IC that learns cell behaviour over many charge cycles. When you install a new cell, the IC still holds calibration data from the old, degraded cell. That mismatch causes the reported percentage to drift — often reading 40% when the cell is near empty. One full slow-charge cycle from 0% to 100% resets the learned curve and brings the displayed percentage back into alignment with actual cell voltage.\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 cell voltage drops below the modem or display load threshold before the fuel gauge registers critical. A fresh cell with an uncalibrated coulomb counter cannot accurately predict the voltage cliff under high-current draw. The Pixel 2's power IC cuts the system before Android can log a low-battery warning. Run one full discharge cycle without fast charging — once the fuel gauge has a real baseline, shutdowns at 20–30% stop.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43405102088282,"sku":"BWCS-HTW333XL-1","price":26.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43405102121050,"sku":"BWCS-HTW333XL-2","price":30.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43405102153818,"sku":"BWCS-HTW333XL-3","price":33.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HTW333XL-big.webp?v=1779369955","url":"https:\/\/batteryweb.com\/products\/google-g8-replacement-battery-37v-2200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
