It covers OEM part numbers including AS07A32, AS07A51, AS07A72, AS07A41, and AS07A52, among others. If your Aspire no longer holds a charge or shuts down unexpectedly, this is the direct swap.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eAspire 4710Z series compatibility:\u003c\/strong\u003e\n    These models share an 11.1V three-cell architecture with the same connector pinout and BMS handshake sequence. The fuel gauge IC communicates over the same SMBus protocol across all listed Aspire variants, so one cell fits the full group without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge and discharge cycles on an Aspire platform. The BMS negotiated correctly with the laptop's charge controller, accepted a full charge without flagging an error, and released current under display-plus-CPU load without tripping the protection circuit.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle calibration after install:\u003c\/strong\u003e\n    After fitting this battery, run it down until the laptop hibernates on low charge, then charge it uninterrupted to 100%. This single cycle forces the BIOS battery learn cycle to reset against the new cell's actual capacity and clears the inaccurate health warning that almost always appears after a cell swap on Aspire hardware.\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\"\u003eThe Aspire BIOS stores battery health data in EEPROM tied to the original cell's charge history. When a new cell is fitted, that stored data doesn't match the new cell's state, so the BIOS flags it as degraded — even though the cell is new. This is not a fault with the replacement. Running one full discharge-to-hibernate followed by an uninterrupted charge to 100% resets the learn cycle and allows the BIOS to write fresh health data against the new cell. After two to three of these calibration cycles, the reported health figure stabilises.\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 hasn't calibrated against the new cell yet — it misjudges remaining capacity because it's still referencing discharge curves from the old cell. Under full CPU and display load, actual cell voltage drops faster than the gauge predicts, and the protection circuit cuts power before the screen gauge reaches zero. The fix is the same calibration cycle: discharge to hibernate-cutoff, then charge fully to 100% without interruption. After two full cycles, the gauge IC recalibrates and shutdowns at false-low readings stop. Target charge before testing is 100% confirmed in both the OS indicator and BIOS.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43410853724250,"sku":"BWCS-AC4310NB-1","price":68.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43410853757018,"sku":"BWCS-AC4310NB-2","price":79.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43410853789786,"sku":"BWCS-AC4310NB-3","price":87.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-AC4310NB-1.webp?v=1779581356","url":"https:\/\/batteryweb.com\/products\/acer-aspire-4710z-replacement-battery-111v-4400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
