It replaces OEM part BLP823 and fits the same internal cavity at 91.10 × 62.40 × 4.70mm. Swap it when your original cell no longer holds charge or causes unexpected shutdowns.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eReno5 Pro and Reno5 Pro 5G compatibility:\u003c\/strong\u003e\n    Both CPH2201 and PDST00 variants use the same BLP823 cell, voltage rail, flex connector, and BMS handshake — the 5G modem draws higher peak current, but the battery architecture is identical across both models.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell on a Reno5 Pro unit and confirmed the BMS negotiates correctly with Oppo's charge IC — full charge acceptance was achieved and no false cutoff events were triggered under sustained load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle recalibration on the Reno5 Pro:\u003c\/strong\u003e\n    On first use after installation, disable fast charging for one complete discharge-charge cycle. This lets the fuel gauge IC recalibrate its coulomb counter against the new cell's discharge curve before high-current charging pushes power 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 Reno5 Pro after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Reno5 Pro's fuel gauge IC retains the discharge curve from the old, degraded cell. When the new cell arrives with a different impedance profile, the gauge miscalculates remaining charge. Under modem or screen load, voltage drops below the system cutoff threshold before the percentage display reaches zero. One full discharge-charge cycle without fast charging forces the coulomb counter to rebuild its model against the new cell.\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 successful BMS authentication handshake before the charge IC allows high-current delivery. On a freshly installed cell, the BMS may default to standard 5V\/1A charging on the first cycle while it verifies the cell parameters. This is not a fault — it clears after the first complete charge. If VOOC still fails to activate after two full cycles, confirm the flex connector is fully seated, as a partial connection breaks the data line the charge IC uses for protocol negotiation.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43391872172122,"sku":"BWCS-OPR520SL-1","price":31.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43391872204890,"sku":"BWCS-OPR520SL-2","price":36.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43391872237658,"sku":"BWCS-OPR520SL-3","price":40.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-OPR520SL-1.webp?v=1779142430","url":"https:\/\/batteryweb.com\/products\/oppo-reno5-pro-replacement-battery-774v-2100mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
