It matches the OEM voltage rail and connector, restoring untethered use to a machine that's stopped holding charge. Capacity figure is 97.68Wh — confirmed against the product data, not the web listing.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eD525 and D725 share the same battery platform:\u003c\/strong\u003e\n    Both models run the same 11.1V three-cell architecture and use identical OEM part numbers across the AS07A series. The BMS handshake and connector pinout are the same on both, so one replacement cell covers either unit without modification.\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 full discharge on the D525 chassis. The BMS held cutoff correctly at both ends, and the protection circuit tripped as expected on overcurrent. No thermal event on charge.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap calibration on the D525:\u003c\/strong\u003e\n    After installing, run one full discharge to hibernate cutoff, then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears after every 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 D525 BIOS flags the replacement cell as poor health immediately after install\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe D525 BIOS reads health data from the battery's EEPROM on first contact. The replacement cell's EEPROM starts with factory defaults that don't match the charge history the BIOS expects. That mismatch triggers a false \"poor health\" or \"consider replacing\" flag before a single cycle has run. Running the battery learn cycle — full discharge to hibernate, then uninterrupted charge to 100% — pushes the BIOS to recalculate health against real cycle data. After two or three full cycles, the flag clears on most D525 units.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eD525 shutting down at 20–30% charge shown on screen\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a voltage cliff, not a faulty cell. Under combined CPU and display load, the cell voltage drops faster than the fuel gauge IC can track. When the real cell voltage hits the BMS low-cutoff threshold, the system shuts off — even though the OS gauge still shows 20–30%. The fuel gauge IC needs calibration cycles against the new cell chemistry before its readings are accurate. Run two full discharge-to-hibernate and charge-to-100% cycles. After that, the shutdown and the displayed percentage should align within a few percent.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43410815811674,"sku":"BWCS-AC4310DB-1","price":123.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43410815844442,"sku":"BWCS-AC4310DB-2","price":142.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43410815877210,"sku":"BWCS-AC4310DB-3","price":155.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-AC4310DB-1.webp?v=1779581180","url":"https:\/\/batteryweb.com\/products\/emachines-d525-replacement-battery-111v-8800mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
