It replaces OEM part number C11-P03 — the original cell that powers the tablet during use. If your Padfone 2 no longer holds a charge, shuts down unexpectedly, or won't power on at all, this is the correct replacement cell.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePadfone 2 and A68 compatibility:\u003c\/strong\u003e\n    Both variants use the same battery bay dimensions and connector pinout. The C11-P03 cell fits either board revision without modification to the connector or housing.\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 Padfone 2 platform. The BMS accepted charge handshake correctly and held voltage within spec across the full cycle without tripping protection cutoff.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration after install:\u003c\/strong\u003e\n    After fitting this battery, run one full discharge to automatic shutoff, then charge uninterrupted to 100%. The Padfone 2 fuel gauge IC calibrates to the installed cell during this cycle. Skipping it causes percentage drift from the first charge.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePadfone 2 shutting down at 15–25% remaining after battery swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a fuel gauge IC issue, not a cell defect. The gauge IC stores calibration data tied to the old cell's internal resistance curve. When the cell is replaced, the reported percentage drifts — the tablet thinks it has charge left but the actual cell voltage has already dropped below the system cutoff threshold. Under combined display and WiFi load, voltage sags faster than the uncalibrated gauge tracks. Running one full discharge-to-shutoff cycle followed by an uninterrupted charge to 100% resets the calibration and resolves the premature cutoff.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eFast charging unavailable on Padfone 2 after cell replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Padfone 2 charge IC uses a protocol handshake at the start of each charge session to determine the safe fast-charge rate for the connected cell. On a freshly installed battery, this negotiation may default to slow charge on the first cycle. This is not a fault with the charger or the cell. Connect the original Asus charger and complete one full charge cycle from low to 100% — on the second cycle, the charge IC accepts the higher current rate and fast charging resumes.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426029830234,"sku":"BWCS-AUP003SL-1","price":45.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426029863002,"sku":"BWCS-AUP003SL-2","price":53.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426029895770,"sku":"BWCS-AUP003SL-3","price":59.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-AUP003SL-1.webp?v=1779930195","url":"https:\/\/batteryweb.com\/products\/asus-padfone-2-tablet-replacement-battery-38v-5100mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
