It replaces OEM part BLP929 directly. Fit this when the original cell has degraded, holds little charge, or fails to power the phone at all.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eReno8 Pro+ and PFZM10 compatibility:\u003c\/strong\u003e\n    Both model designations share the same chassis, BLP929 connector pinout, and charge IC handshake. The BMS communicates with the Oppo charge controller over the same protocol, so no firmware mismatch occurs on either variant.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through a full discharge-charge sequence on a Reno8 Pro+ unit. The BMS accepted the charge IC handshake on the first cycle, and the fuel gauge IC began tracking capacity correctly after one complete cycle without intervention.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle fast charge behaviour:\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 recalibrate its coulomb counter against the new cell's discharge curve before high-current fast charging pushes load into an uncalibrated state.\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 replacement cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA new cell has a different discharge curve than the worn cell the fuel gauge IC was originally calibrated against. When the phone hits a voltage point that the old curve mapped to 20–30%, the new cell may actually be near its minimum sustainable voltage under modem or display load. The charge controller sees a voltage cliff and shuts the phone down before the OS registers 0%. One full discharge-to-shutdown followed by a complete charge cycle resets the coulomb counter and eliminates this behaviour.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSUPERVOOC fast charge not activating after replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eOppo's SUPERVOOC protocol requires the charge IC to authenticate with the battery BMS before allowing high-current delivery. On a new cell, this handshake occasionally fails on the first cycle because the BMS has not yet completed its initialisation sequence. Plug in using the original Oppo cable and adapter, let the phone charge to 100% on standard charge, then unplug and replug — SUPERVOOC will activate once the BMS has completed one full cycle and the handshake registers correctly.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43391835242586,"sku":"BWCS-OPR812SL-1","price":39.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43391835275354,"sku":"BWCS-OPR812SL-2","price":45.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43391835308122,"sku":"BWCS-OPR812SL-3","price":50.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-OPR812SL-1.webp?v=1779142265","url":"https:\/\/batteryweb.com\/products\/oppo-reno8-pro-replacement-battery-774v-2200mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
