It fits all regional variants including the Rain edition. Use this when the original BLP633 cell has degraded past the point of holding a useful charge or is causing unexpected shutdowns.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e3T and A3010 variant coverage:\u003c\/strong\u003e\n    The 3T, 3T Dual SIM, Rain, and A3010 all share the same battery bay dimensions, connector pinout, and BMS handshake protocol — one cell fits all four 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 charge and discharge cycles on a 3T unit. The BMS accepted the cell without fault flags, and the charge IC engaged Dash Charge protocol correctly after the first full cycle.\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 Dash Charge for one complete discharge-charge cycle. This lets the fuel gauge IC build an accurate discharge curve against the new cell before high-current charging begins on an uncalibrated counter.\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 3T after a cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a voltage cliff problem, not a capacity problem. A new cell with a slightly different discharge curve will hit the low-voltage cutoff threshold while the fuel gauge IC still reads 20–30% remaining — because the IC is still calibrated to the old cell. The BMS cuts power to protect the cell before the OS can react. One full discharge-to-zero and slow recharge cycle resets the coulomb counter and eliminates the false-floor shutdown.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eOS percentage jumping erratically after battery replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe OnePlus 3T uses a coulomb counter in the fuel gauge IC to track remaining capacity. When the original cell is replaced, the IC has no baseline for the new cell's actual capacity and internal resistance. This mismatch causes the percentage reading to jump — sometimes 10–15 points in either direction under load or during charging. Perform one full uninterrupted discharge down to auto-off, then charge to 100% without interruption at standard charge speed to re-anchor the counter.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43392070385754,"sku":"BWCS-YJT310SL-1","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43392070418522,"sku":"BWCS-YJT310SL-2","price":29.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43392070451290,"sku":"BWCS-YJT310SL-3","price":32.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-YJT310SL-1.webp?v=1779143562","url":"https:\/\/batteryweb.com\/products\/oneplus-3t-replacement-battery-385v-3000mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
