It fits the Oppo CPH2481, Reno8 T, and Reno8 T 4G. If your original cell is swelling, failing to hold charge, or cutting out before the percentage hits zero, this is a direct cell replacement.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCPH2481 \/ Reno8 T platform fit:\u003c\/strong\u003e\n    The CPH2481 and Reno8 T 4G share the same battery bay geometry, connector pinout, and BMS handshake logic — all three models use BLP959 as the factory cell. No adapter or rewiring needed.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through full charge and discharge on the CPH2481 platform. The BMS accepted the cell without fault codes, and the charge IC handed off correctly at 4.40V cutoff.\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. This gives the fuel gauge IC time to map the new cell's discharge curve before high-current SUPERVOOC pushes 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\"\u003eSudden shutdown at 20–30% on the Reno8 T after a cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the fuel gauge IC is still using the discharge curve from the old, degraded cell. The new cell has a steeper voltage cliff at low state-of-charge — the phone sees voltage drop under modem or display load and triggers an emergency shutdown before the percentage reaches zero. One full discharge-charge cycle without fast charging lets the coulomb counter reset against the new curve. After that cycle, the reported percentage and actual cell voltage track correctly again.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSUPERVOOC fast charge not activating after battery replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eOppo's SUPERVOOC protocol requires a handshake between the charge IC and the battery's BMS before elevated current is allowed. On the first cycle with a new cell, the BMS may default to standard 5V\/2A charging until it completes an initialisation cycle. Plug into the original SUPERVOOC charger, let the phone charge to 100% without interruption, then restart the device. After reboot, the fast charge negotiation re-runs and SUPERVOOC should activate normally on the next charge.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43391780814938,"sku":"BWCS-OPR248SL-1","price":43.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43391780847706,"sku":"BWCS-OPR248SL-2","price":51.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43391780880474,"sku":"BWCS-OPR248SL-3","price":56.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-OPR248SL-1.webp?v=1779141908","url":"https:\/\/batteryweb.com\/products\/oppo-cph2481-replacement-battery-387v-4850mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
