It fits the Oppo A60 4G (model code CPH2631). If your A60 4G is shutting down unexpectedly, failing to charge, or not powering on at all, this cell replaces the original unit directly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eA60 4G \/ CPH2631 fitment:\u003c\/strong\u003e\n    Both model references share the same physical cell footprint, BLPA49 OEM part number, and BMS connector pinout. One cell covers both variants — no hardware differences between them that affect battery compatibility.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran charge and discharge cycles through the A60 4G charge IC and confirmed the BMS handshake completed correctly. The fuel gauge IC accepted the new cell and began coulomb counting without throwing a fault state.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first cycle:\u003c\/strong\u003e\n    On first use after installation, disable fast charging and run one full discharge down to automatic shutdown, then charge to 100% on standard current. This gives the fuel gauge IC a clean reference curve against the new cell before high-current charging is applied to 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 A60 4G after a cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA new Li-Polymer cell has a slightly different discharge curve than the aged cell the fuel gauge IC was calibrated against. When load spikes — modem transmitting, screen at full brightness — the cell voltage drops sharply in that uncalibrated zone. The fuel gauge reads that voltage drop as empty and triggers an emergency shutdown even though capacity remains. One complete discharge-charge cycle on standard current recalibrates the coulomb counter and resolves this. After that cycle, shutdowns at 20–30% should stop.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eOppo A60 4G not powering on after the battery sat discharged in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-Polymer cells that drop below approximately 2.5V enter a BMS lockout state — the protection circuit opens to prevent cell damage, and the phone shows nothing when you press the power button. Plug in a known-good charger and leave it connected for 15–20 minutes without attempting to power on. The charge IC applies a low trickle current that brings the cell above the BMS re-enable threshold, typically around 2.8–3.0V. Once the BMS re-initialises, normal charging resumes and the device will power on.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43391772164186,"sku":"BWCS-OPA600SL-1","price":43.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43391772196954,"sku":"BWCS-OPA600SL-2","price":51.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43391772229722,"sku":"BWCS-OPA600SL-3","price":56.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-OPA600SL-1.webp?v=1779141871","url":"https:\/\/batteryweb.com\/products\/oppo-a60-4g-replacement-battery-391v-4850mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
