It replaces a broad family of OEM part numbers including AS07A32, AS07A51, AS07A72, and AS09A61, among others. If the original cell has degraded, stopped charging, or is no longer recognised by the system, this cell installs directly in its place.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eD525 and D725 compatibility:\u003c\/strong\u003e\n    Both models share the same battery bay geometry, connector pinout, and BMS communication protocol. The same 11.1V three-cell architecture runs across this platform, so one cell covers both without adapter or firmware 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-to-cutoff and load discharge on the D525 platform. The BMS handshake completed on first insertion, charge current was accepted immediately, and the protection circuit responded correctly at both high-temperature and deep-discharge thresholds.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration on the D525:\u003c\/strong\u003e\n    After fitting this battery, run one full discharge down to hibernate-cutoff, then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health or capacity 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\"\u003eBIOS reporting poor battery health immediately after installation\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe D525 BIOS reads health data from EEPROM registers stored on the old cell. When a new cell installs, those registers are blank or mismatched, and the BIOS flags it as degraded before any charge cycle runs. This is a firmware read issue, not a fault with the replacement cell. Run one full discharge-to-hibernate followed by a complete uninterrupted charge. After that cycle, the BIOS recalibrates its health estimate against the actual cell data.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop 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 against the new cell's voltage curve. The percentage shown does not match real remaining capacity, so the system cuts power before the display reaches 0%. It is not a fault with the cell itself. Run two to three full discharge-and-charge cycles without interruption — by the third cycle, the gauge IC maps the correct curve and the shutdown threshold stabilises at the true low-voltage cutoff near 9.0V.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43410815516762,"sku":"BWCS-AC4310HB-1","price":121.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43410815549530,"sku":"BWCS-AC4310HB-2","price":139.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43410815582298,"sku":"BWCS-AC4310HB-3","price":152.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-AC4310HB-1.webp?v=1779581180","url":"https:\/\/batteryweb.com\/products\/emachines-d525-replacement-battery-111v-6600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
