It fits the ProBook 5330m series across multiple regional variants, including the LV720PA, QC518PA, and SP451UC. OEM cross-references include FN04, HSTNN-DB0H, QK648AA, and 634818-271.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eProBook 5330m series compatibility:\u003c\/strong\u003e\n    All ProBook 5330m variants share the same 14.8V four-cell Li-Polymer voltage rail, connector pinout, and BMS handshake protocol — that is why one part number covers the full regional lineup.\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 a ProBook 5330m unit. The BMS completed the full handshake, reported cell presence correctly in BIOS, and charge termination triggered cleanly at 16.8V across all four cells.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration on the ProBook 5330m:\u003c\/strong\u003e\n    After fitting this battery, 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\"\u003eBIOS reporting battery health as poor after replacement\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe ProBook 5330m BIOS reads health data stored in the battery's EEPROM. When a new cell is installed, the EEPROM contains factory defaults that don't match the BIOS's accumulated charge history from the old battery. The system flags this mismatch as a health warning — it is not a fault with the replacement cell. Running one full discharge-to-hibernate followed by a full uninterrupted charge completes the battery learn cycle and clears the warning.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eProBook 5330m shutting down at 20–30% charge shown\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 discharge curve. The gauge estimates remaining charge using data from the old, degraded cell — so it reads 25% while the new cell is already near its voltage floor. Under full CPU and display load, the cell hits its low-voltage cutoff faster than the gauge predicts, and the laptop shuts off without warning. Run two to three full discharge-to-hibernate and full recharge cycles until the gauge stabilises — the cutoff should shift below 10% once calibration is complete.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409736368218,"sku":"BWCS-HPB533NB-1","price":71.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409736400986,"sku":"BWCS-HPB533NB-2","price":85.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409736433754,"sku":"BWCS-HPB533NB-3","price":94.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HPB533NB-1.webp?v=1779580582","url":"https:\/\/batteryweb.com\/products\/hp-probook-5330m-replacement-battery-148v-2700mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
