It replaces OEM part AC17A8M and the alternate reference 3ICP7\/61\/80. The cell fits the 2-in-1 chassis and connects through the original BMS-controlled interface.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSpin 3 and TravelMate X3410 platform fit:\u003c\/strong\u003e\n    Both series run the same 11.55V three-cell architecture with an identical connector pinout and BMS handshake protocol. That shared rail is why one part number covers both chassis families without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell on the SP314-52 platform through full charge and discharge under combined CPU and display load. The BMS communicated state-of-charge correctly and protection circuits tripped at the expected low-voltage threshold.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration on the Spin 3:\u003c\/strong\u003e\n    After fitting, run the battery down until the laptop hibernates, then charge uninterrupted to 100% without interruption. This resets the BIOS battery learn cycle and clears the inaccurate health warning that typically 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\"\u003eBIOS reporting poor battery health immediately after replacement\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eAcer's BIOS reads health data from EEPROM registers on the battery controller, not from live cell voltage. When a new cell is installed, those registers still carry stale data from the old pack. The BIOS flags this as degraded health before the fuel gauge IC has run a single calibration pass. One full discharge-to-hibernate followed by a complete uninterrupted charge cycle writes fresh data to those registers. After that cycle, the health indicator clears on the SP314-52 without any firmware update.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop shuts 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 against the new cell's actual voltage curve. The OS reads a percentage from a lookup table built on the old cell's degraded profile, so the number on screen no longer maps to real remaining capacity. When the cell voltage drops below the BMS cutoff threshold — roughly 9.0V under load on this three-cell pack — the system shuts down even though the gauge still shows charge remaining. Run two complete discharge-to-hibernate and full-recharge cycles to let the fuel gauge IC re-map the voltage curve against the new cell.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409694851162,"sku":"BWCS-ACP314NB-1","price":73.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409694883930,"sku":"BWCS-ACP314NB-2","price":85.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409694916698,"sku":"BWCS-ACP314NB-3","price":94.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ACP314NB-1.webp?v=1779580452","url":"https:\/\/batteryweb.com\/products\/acer-spin-3-sp314-52-599w-replacement-battery-1155v-5300mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
