It fits the ME70CX, K01A, and ME7000C variants using OEM part number B11P1405 (also listed as B11Bk9H). Swap it in when the original cell no longer holds a usable charge or stops accepting power altogether.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eME70CX, K01A, and ME7000C compatibility:\u003c\/strong\u003e\n    These models share the same 3.85V single-cell architecture, connector footprint, and charge IC handshake — one cell fits all three without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this battery through charge and discharge on the ME70CX mainboard. The BMS accepted the charge IC handshake cleanly, held the 3.85V nominal rail, and triggered the low-voltage cutoff at the correct threshold with no false trips.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration after install:\u003c\/strong\u003e\n    After fitting this battery, run the tablet down to automatic shutoff, then charge it uninterrupted to 100% without using it. This forces the fuel gauge IC to recalibrate against the new cell and clears the inaccurate percentage readings that commonly appear after any battery swap.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eTablet shutting down at 15–25% remaining after battery replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe ME70CX draws a combined load from the display backlight and Wi-Fi radio that causes a sharp voltage sag at low state-of-charge. The fuel gauge IC, still calibrated to the old cell's discharge curve, misreads the voltage cliff and triggers an emergency shutdown before the percentage reaches zero. The fix is one full recalibration cycle — discharge to automatic shutoff, then charge uninterrupted to 100%. After that cycle, the fuel gauge maps the new cell's curve correctly and the early shutdowns stop.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eFast charging unavailable on the ME70CX after a battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe charge IC on the ME70CX uses a negotiation step at the start of the first charge cycle to confirm cell parameters before enabling higher charge rates. On a new cell, this negotiation sometimes defaults to standard rate until one complete charge cycle is accepted. Plug in using the original charger and cable — third-party cables with high resistance can mask the negotiation signal. After one full charge to 100%, the charge IC locks in the correct profile and fast charging becomes available again.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43425898299482,"sku":"BWCS-AUM710SL-1","price":29.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43425898332250,"sku":"BWCS-AUM710SL-2","price":33.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43425898365018,"sku":"BWCS-AUM710SL-3","price":36.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-AUM710SL-1.webp?v=1779930007","url":"https:\/\/batteryweb.com\/products\/asus-memo-pad-7-me70cx-replacement-battery-385v-3050mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
