It fits the Z300C and P023 variants, along with the ZenPad 10.1 and related models covered under OEM part numbers C11P1502 and C11P1517. Physical dimensions are 119.15 × 107.20 × 2.65mm — confirm clearance before ordering if your unit has been previously repaired.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eZ300C and P023 platform fit:\u003c\/strong\u003e\n    These models share the same battery bay dimensions, connector pinout, and BMS handshake protocol. The C11P1502 and C11P1517 part numbers are interchangeable across this platform because ASUS used the same fuel gauge IC and charge controller across both production runs.\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 a Z300C unit. The BMS communicated correctly with the charge IC, reported accurate state-of-charge data, and did not trigger overcurrent cutoff during display-plus-WiFi load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge IC reset after installation:\u003c\/strong\u003e\n    After fitting the new cell, run the tablet down to automatic shutoff, then charge uninterrupted to 100% without using the device. This resets the fuel gauge IC calibration against the new cell and clears the inaccurate percentage readings that appear after a battery swap.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the ZenPad 10 shuts down at 15–25% remaining\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eWhen the display backlight and WiFi radio draw current simultaneously, voltage drops sharply at the cell terminals. If the fuel gauge IC is still calibrated to an old or degraded cell, it reads 15–25% remaining but the actual terminal voltage has already crossed the BMS cutoff threshold. The tablet shuts down not because charge is gone, but because voltage has sagged below the protection floor. Running one full discharge-to-shutoff cycle recalibrates the gauge to the new cell's actual voltage curve and eliminates false shutoffs.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eFast charging unavailable after battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe ZenPad 10 charge IC uses a negotiation handshake before enabling higher charge rates on a new cell. Until the controller has completed one accepted full charge cycle, it defaults to standard current limits as a safety measure. This is not a fault with the replacement cell. Plug into the original Asus charger, let the tablet charge from low to 100% without interruption, and fast charging resumes on the next session.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43425958625370,"sku":"BWCS-AUC300SL-1","price":34.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43425958658138,"sku":"BWCS-AUC300SL-2","price":40.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43425958690906,"sku":"BWCS-AUC300SL-3","price":44.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-AUC300SL-1.webp?v=1779930008","url":"https:\/\/batteryweb.com\/products\/asus-zenpad-10-replacement-battery-38v-4700mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
