It replaces OEM part AP15A3R using the same flat-cell construction the chassis requires. The ultra-slim 3.60mm cell profile fits within the tablet half of the Switch 10E without modification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSW3-013 and SW3-013-1566 compatibility:\u003c\/strong\u003e\n    Both models run the same 3.75V battery rail with an identical connector and BMS communication protocol — they share this cell because Acer used one battery platform across the SW3-013 line regardless of storage or CPU variant.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through charge and discharge on the SW3-013 platform, confirmed the BMS handshake completed without fault codes, and verified the fuel gauge IC registered the correct 8050mAh capacity rather than defaulting to the old cell's EEPROM data.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration on the Switch 10E:\u003c\/strong\u003e\n    After fitting, run the battery down to hibernate cutoff — let the system sleep itself, not a forced shutdown — then charge uninterrupted to 100%. This forces the BIOS battery learn cycle to reset against the new cell and clears the inaccurate health warning that almost always appears after a cell swap on this platform.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Switch 10E BIOS reports poor battery health immediately after a swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Switch 10E BIOS reads health data from the battery's EEPROM, which stores cycle count and rated capacity from the original cell. When a new cell goes in, that EEPROM data does not match the fresh chemistry, so the BIOS flags it as degraded. This is a data mismatch, not a fault with the replacement cell. Running one full calibration cycle — full discharge to hibernate, full charge to 100% — allows the fuel gauge IC to write new baseline data and clears the warning. After two or three cycles the health reading stabilises at a normal figure.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSwitch 10E shutting down at 20–30% charge shown on screen\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the fuel gauge IC has not yet calibrated to the new cell's actual voltage curve. The meter shows 25% while the cell voltage is already dropping below the load-sustain threshold under combined CPU and display draw. The system hits the low-voltage cutoff and shuts down before the percentage reaches zero. Run two full discharge-to-hibernate and full-charge cycles — by the second cycle the gauge IC recalibrates and the cutoff aligns correctly with the displayed percentage, which should track down to around 3.5V per cell before shutdown.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409740071002,"sku":"BWCS-ACW103NB-1","price":70.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409740103770,"sku":"BWCS-ACW103NB-2","price":82.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409740136538,"sku":"BWCS-ACW103NB-3","price":91.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ACW103NB-1.webp?v=1779580583","url":"https:\/\/batteryweb.com\/products\/acer-aspire-switch-10e-replacement-battery-375v-8050mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
