It replaces OEM part number BLP855. Fit this battery when the original no longer holds charge, shuts down unexpectedly, or fails to power the phone.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eReno6 Pro 5G and PEPM00 fit:\u003c\/strong\u003e\n    Both model designations share the same battery bay dimensions, connector pinout, and BLP855 BMS handshake. The flex connector locks to the same 4-pin socket on both board revisions, so no adapter or modification is needed.\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 Reno6 Pro 5G board. The BMS accepted the charge IC handshake on first connection, and cell voltage held within spec across the full discharge curve without triggering BMS overcurrent cutoff.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle fast charge protocol:\u003c\/strong\u003e\n    On first use after installation, disable SUPERVOOC fast charging for one complete discharge-charge cycle. This lets the fuel gauge IC map the new cell's discharge curve before high-current charging pushes 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 Reno6 Pro 5G after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Reno6 Pro 5G's fuel gauge IC stores a 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 AMOLED panel together pull enough current to expose the mismatch — the phone sees voltage drop below the shutdown threshold even though the percentage display still reads 20–30%. Running one full discharge to auto-off, followed by an uninterrupted charge to 100%, forces the coulomb counter to resync against the new cell. After that cycle, shutdown behaviour returns to normal.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSUPERVOOC fast charging not activating on the first cycle after replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eSUPERVOOC uses a proprietary handshake between the charge IC, BMS, and charger adapter. On a freshly installed cell, the BMS defaults to standard 5V\/2A charging on the first connection while it validates cell impedance. This is not a fault — it is protective behaviour. Unplug the charger, wait 10 seconds, and reconnect. If SUPERVOOC still does not activate after the first full charge cycle, check that the original Oppo 65W adapter is in use, as third-party adapters will not initiate the protocol.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43391836553306,"sku":"BWCS-OPR855SL-1","price":32.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43391836586074,"sku":"BWCS-OPR855SL-2","price":37.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43391836618842,"sku":"BWCS-OPR855SL-3","price":41.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-OPR855SL-1.webp?v=1779142265","url":"https:\/\/batteryweb.com\/products\/oppo-reno6-pro-5g-replacement-battery-774v-2200mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
