This is a convertible 2-in-1 Chromebook — it runs as both a notebook and a tablet. The replacement restores power to a unit where the original cell has degraded or stopped holding charge.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eR752T series compatibility:\u003c\/strong\u003e\n    All R752T variants listed share the same 11.55V voltage rail, physical connector, and BMS handshake profile. The AP19A5K part number spans the full sub-range, so the same cell works across those 16+ model suffixes without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran the cell through charge and discharge cycles on the R752T platform. The BMS negotiated correctly with the Chromebook's charge controller, accepted a full charge to 11.55V, and hit rated capacity without triggering any protection cutoff during the draw phase.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration on ChromeOS:\u003c\/strong\u003e\n    After fitting the new cell, run one full discharge until the Chromebook hibernates, then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears in ChromeOS diagnostics after a cell 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 R752T shuts down at 20–30% after a battery swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe fuel gauge IC on the R752T motherboard stores calibration data from the original cell. After a swap, that data no longer matches the new cell's discharge curve. The Chromebook reads a voltage level that looks critical to the old curve and cuts power — even though actual capacity remains. Running two or three full discharge-and-charge cycles forces the fuel gauge IC to remap against the new cell's actual voltage cliff, which typically sits below 10.8V under combined CPU and display load.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eChromeOS Diagnostics showing incorrect Wh rating after replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Wh figure shown in ChromeOS Diagnostics pulls from EEPROM data written by the battery's own management chip, not from a live capacity measurement. A new AP19A5K cell carries EEPROM values rated to the cell's nominal chemistry, which can display as a slightly different Wh number than the original OEM pack. This is not a fault — the cell is delivering the correct 39.27Wh. Confirm actual charge level by checking the status bar percentage rather than the Diagnostics Wh readout.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409539432538,"sku":"BWCS-ACS511NB-1","price":86.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409539465306,"sku":"BWCS-ACS511NB-2","price":102.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409539498074,"sku":"BWCS-ACS511NB-3","price":114.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ACS511NB-1.webp?v=1779579964","url":"https:\/\/batteryweb.com\/products\/acer-chromebook-spin-511-r752t-c3m5-replacement-battery-1155v-3400mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
