It cross-references OEM part numbers AS16B5J, AS16B8J, and KT.0060G.001. The connector, pin count, and BMS communication protocol match the original specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eAspire E5\/F5 platform compatibility:\u003c\/strong\u003e\n    These models share a common board architecture, battery connector, and BMS handshake protocol across the E5-575, E5-575G, and F5-573G lines. The same voltage rail and physical form factor let one cell cover all of them without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell on an E5-575G board and confirmed the BMS initialised correctly, charge current stepped down at the expected voltage threshold, and the system did not flag a protection-circuit fault during the first full cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle calibration after swap:\u003c\/strong\u003e\n    After installing, discharge fully until the laptop hibernates, then charge uninterrupted to 100% without interruption. This triggers the BIOS battery learn cycle, clears the inaccurate health warning that appears after every cell swap, and lets the fuel gauge IC baseline against the new cell chemistry.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBIOS reporting battery health as poor immediately after replacement\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eAcer's BIOS stores charge history and health data from the previous cell in firmware. When a new cell goes in, that cached data does not automatically reset — so the system reads the old degraded profile and flags poor health regardless of actual cell condition. Running one complete discharge-to-hibernate followed by an uninterrupted charge to 100% forces the BIOS learn cycle to rewrite that profile. After two or three full cycles, the health indicator should clear and report normally.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop shuts down abruptly 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. At high CPU and display load, the cell's terminal voltage drops faster than the uncalibrated gauge predicts, and the system hits undervoltage cutoff while the OS still shows 20–30%. It is not a fault with the replacement cell. Run two full discharge-to-hibernate cycles back-to-back, letting each complete without plugging in early, then charge to 100%. By the third cycle the gauge typically tracks the real voltage curve and the premature shutdowns stop.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409726570586,"sku":"BWCS-ACP259NB-1","price":111.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409726603354,"sku":"BWCS-ACP259NB-2","price":127.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409726636122,"sku":"BWCS-ACP259NB-3","price":139.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ACP259NB-1.webp?v=1779580541","url":"https:\/\/batteryweb.com\/products\/acer-aspire-e5-575g-53vg-replacement-battery-111v-5200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
