It fits the original battery bay without modification. Swap it when your Pixel 2 shuts down early, charges slowly, or no longer holds a full day of charge.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePixel 2 (Muski \/ 2B) fit:\u003c\/strong\u003e\n    Both Pixel 2 variants use the same BG2W cell with identical voltage rails, connector pinout, and BMS handshake. One SKU covers both board revisions — no adapter or harness swap needed.\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 mainboard and confirmed the BMS handshake completed, charge IC accepted the cell on first connect, and voltage held stable under full modem and display load.\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 before enabling Adaptive Charging. This lets the fuel gauge IC map the new cell's discharge curve before high-current pulses are applied to 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 Pixel 2 after a battery swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Pixel 2 fuel gauge IC stores a learned discharge curve from the old cell. When a new cell goes in, that curve no longer matches actual cell voltage under load. The modem and display draw a combined surge the old curve doesn't account for, so the IC reads a false low-voltage condition and triggers an emergency shutdown — even though the cell still has charge. One full discharge cycle below 5% and a complete charge to 100% forces the coulomb counter to rebuild its reference table against the new cell.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eUSB-PD fast charge not accepted on the first cycle after replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eAfter a cell swap, the Pixel 2 charge IC defaults to trickle charge on the first connect while it checks cell impedance. If the phone doesn't recognise a fast charge handshake in this window, it stays in standard charge mode for the entire first cycle. This is normal BMS behaviour — not a fault with the cable or charger. Fully discharge and recharge once, and fast charge will re-engage on the second cycle when cell impedance registers within the expected range.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43391994003546,"sku":"BWCS-GPW240SL-1","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43391994036314,"sku":"BWCS-GPW240SL-2","price":28.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43391994069082,"sku":"BWCS-GPW240SL-3","price":31.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-GPW240SL-1.webp?v=1779142762","url":"https:\/\/batteryweb.com\/products\/google-pixel-2b-replacement-battery-385v-2700mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
