It cross-references OEM part numbers including 484788-001, 493976-001, HSTNN-LB60, HSTNN-OB60, HSTNN-XB60, and KU533AA. If your current battery no longer holds charge through a standard work session, this is a direct cell replacement at the same voltage and capacity.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e8530 and 8540 platform compatibility:\u003c\/strong\u003e\n    The 8530p, 8530w, 8540p, and 8540w share the same 14.4V battery bay, connector pinout, and BMS communication protocol. One cell fits all four models without adapter or 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 8530p and confirmed the BMS handshake completed correctly, the BIOS accepted the battery without error flags, and charge regulation cycled through all four charge stages normally.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-installation learn cycle:\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 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 fitting a new cell\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe EliteBook BIOS reads health data from the battery's EEPROM, not from live cell measurements. When a new cell is installed, the EEPROM still carries aged-cell data from the previous battery's firmware log. The BIOS compares current charge acceptance against those stored values and flags the result as degraded. Running one full discharge-to-hibernate then a full uninterrupted charge resets that stored baseline and clears the warning on next boot.\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 cell cannot sustain voltage under combined CPU and display load as it approaches the lower end of its charge curve — a voltage cliff specific to Li-ion cells under high draw. The fuel gauge IC is still reporting a percentage based on an uncalibrated model, so the on-screen number doesn't match actual cell capacity. Run two to three full discharge and charge cycles to let the fuel gauge IC re-map against the new cell. After calibration, the shutdown threshold should stabilise at or below 5%.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43410801459290,"sku":"BWCS-HP8530HB-1","price":112.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43410801492058,"sku":"BWCS-HP8530HB-2","price":128.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43410801524826,"sku":"BWCS-HP8530HB-3","price":140.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HP8530HB-1.webp?v=1779581158","url":"https:\/\/batteryweb.com\/products\/hp-elitebook-8530p-replacement-battery-144v-4400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
