It fits CPH1919, PCCM00, and PCCT00 variants. The cell matches the original's physical dimensions at 66.50 x 64.56 x 4.75mm and drops into the same connector position.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCPH1919 \/ PCCM00 \/ PCCT00 compatibility:\u003c\/strong\u003e\n    All three board revisions share the same battery bay geometry, connector pinout, and BMS handshake voltage thresholds — one cell fits all 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 the Reno 10x Zoom mainboard. The BMS accepted the cell without triggering a fault flag, and the charge IC stepped through trickle, CC, and CV phases as expected.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle calibration tip:\u003c\/strong\u003e\n    On first use after installation, disable VOOC fast charging for one complete discharge-charge cycle. This lets the fuel gauge IC recalibrate against the new cell's discharge curve before high-current charging pushes current into an uncalibrated coulomb 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 Reno 10x Zoom after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Reno 10x Zoom's fuel gauge IC uses a stored discharge curve from the previous cell to estimate remaining capacity. A new cell with a slightly different internal resistance profile will hit a voltage cliff earlier than the old curve predicts. When the modem transmits or the 48MP camera fires, instantaneous current draw causes a sharp voltage dip that the BMS reads as a dead cell — triggering shutdown even though charge remains. Run two full discharge-charge cycles without fast charging and the coulomb counter will remap to the new cell's actual curve.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eVOOC fast charge not activating on the first cycle after replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eOppo's VOOC protocol requires a handshake between the charger, charge IC, and the battery's BMS before elevated current is permitted. On the first cycle with a new cell, the charge IC defaults to standard 5V\/1A input until it confirms the BMS is responding correctly. This is normal behaviour — not a fault. Connect the original VOOC charger, complete one full charge at standard rate, then reconnect. VOOC negotiation should complete and the fast-charge indicator will appear at the lock screen.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43391987908698,"sku":"BWCS-OPR705SL-1","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43391987941466,"sku":"BWCS-OPR705SL-2","price":29.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43391987974234,"sku":"BWCS-OPR705SL-3","price":32.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-OPR705SL-1.webp?v=1779142785","url":"https:\/\/batteryweb.com\/products\/oppo-reno-10x-zoom-replacement-battery-385v-3500mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
