It replaces part number AC630X when the original cell degrades, swells, or stops holding charge. Direct swap for the Oxygen 63 — same voltage, same form factor at 90 x 60 x 4.40mm.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eOxygen 63 fit:\u003c\/strong\u003e\n    The Oxygen 63 uses a fixed 3.8V nominal cell with a matching connector and BMS handshake. This replacement matches that voltage rail and connector pinout so the charge IC and fuel gauge IC communicate correctly from the first boot.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through full charge and discharge on the Oxygen 63 platform. The BMS accepted the cell without fault codes, and the charge IC completed a full CC\/CV cycle to 4.35V without thermal cutoff.\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 for one complete discharge-charge cycle. This lets the fuel gauge IC recalibrate against the new cell's discharge curve before high-current charging pushes current 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 Archos Oxygen 63 after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Oxygen 63 fuel gauge IC retains the discharge curve of the old degraded cell after a swap. When a fresh cell is installed, the coulomb counter's stored curve no longer matches the new cell's actual voltage profile. Under modem or screen load, the phone hits a voltage point the IC interprets as empty — even though capacity remains. One full discharge-to-shutdown followed by an uninterrupted charge to 100% resets the calibration window and resolves premature cutoffs.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eFast charging not activating on the first cycle after replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eAfter a cell replacement, the charge IC on the Oxygen 63 starts in a conservative trickle-charge mode to verify the new cell's impedance before accepting higher current. If the phone shows slow charging on the first cycle, this is the IC running its qualification check — not a fault. Let the first cycle complete at standard rate without interrupting it. Fast charging typically resumes on the second cycle once the IC logs a full charge event against the new cell's internal resistance profile.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43391803457626,"sku":"BWCS-ARC630SL-1","price":33.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43391803490394,"sku":"BWCS-ARC630SL-2","price":39.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43391803523162,"sku":"BWCS-ARC630SL-3","price":43.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ARC630SL-1.webp?v=1779142181","url":"https:\/\/batteryweb.com\/products\/archos-oxygen-63-replacement-battery-38v-3000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
