It replaces OEM part BLPA25 and restores power to the phone's processor, display, and connectivity stack. Fit the cell when your original battery no longer holds a full charge or causes unexpected shutdowns.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eOnePlus 12 and PJD110 compatibility:\u003c\/strong\u003e\n    Both model designations run the same 7.82V nominal voltage rail with the same connector pinout and BMS handshake. One cell covers both variants — no adapter or wiring change 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 the OnePlus 12 platform. The BMS accepted the new cell without fault codes, and the fuel gauge IC began tracking state-of-charge from the first cycle without triggering a protection cutoff.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle fuel gauge reset:\u003c\/strong\u003e\n    After installation, disable SUPERVOOC fast charging and run one full discharge-charge cycle at standard current. This gives the fuel gauge IC a clean reference curve for the new cell before high-current charging begins. Skipping this step can cause the percentage readout to jump or report inaccurately for the first week of use.\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 a fresh cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a voltage cliff, not a capacity fault. Under peak modem load or a high-brightness screen event, the cell voltage drops below the BMS cutoff threshold faster than the fuel gauge expects — so the phone shuts off even though the percentage looks safe. The old cell's discharge curve is burned into the coulomb counter, and the new cell has a slightly different mid-range sag profile. One full discharge to near 0% followed by an uninterrupted charge to 100% resets the counter to the new curve and shifts the cutoff point back down where it belongs.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSUPERVOOC not activating after cell replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eOn the first charge after a cell swap, the OnePlus charge IC runs a brief impedance check on the new cell before handing off to the proprietary fast-charge protocol. If the cell impedance reads above a set threshold — common on a cold or unconditioned cell — the IC falls back to standard 5V charging and SUPERVOOC never negotiates. This is not a charger fault or a cable fault. Charge the phone once at standard current, let the cell warm slightly to operating temperature, then reconnect the SUPERVOOC adapter. The protocol should negotiate normally from the second cycle onward.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43391796674650,"sku":"BWCS-OPL120SL-1","price":43.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43391796707418,"sku":"BWCS-OPL120SL-2","price":51.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43391796740186,"sku":"BWCS-OPL120SL-3","price":56.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-OPL120SL-1.webp?v=1779142181","url":"https:\/\/batteryweb.com\/products\/oneplus-12-replacement-battery-782v-2630mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
