It replaces OEM part numbers 454001-001, 447649-251, 447649-321, HSTNN-DB53, and HSTNN-OB53. It slots into the standard battery bay and connects to the same SMBus interface as the original HP cell.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBusiness Notebook 2210b fit:\u003c\/strong\u003e\n    The 2210b uses a dedicated 8-cell 14.4V battery bay with a specific locking tab alignment and SMBus pin layout. This cell matches that physical format and communicates charge state data back to the HP BIOS over the same two-wire bus the original used.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through full charge and discharge on a 2210b unit, confirmed the BMS reported accurate state-of-charge at each 10% interval, and verified the protection circuit tripped correctly at low-voltage cutoff without a hard shutdown above 10%.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle calibration on the 2210b:\u003c\/strong\u003e\n    After fitting this battery, run the laptop on battery only until Windows triggers hibernate at low charge, then plug in and charge uninterrupted to 100%. This forces the HP BIOS to complete a battery learn cycle and clears the \"Battery health — poor\" flag that appears after every cell swap on this model.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the 2210b BIOS flags a new battery as unknown or poor health\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe HP 2210b reads battery health from EEPROM data stored on the cell's embedded controller, not from live voltage measurements. When a new cell arrives, that EEPROM contains factory defaults the BIOS doesn't recognise as a \"known good\" cycle history. The BIOS then displays a health warning even though the cell is new and fully functional. One complete discharge-to-hibernate followed by a full uninterrupted charge writes a valid cycle baseline and clears the flag.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003e2210b shutting down at 20–30% charge remaining\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis symptom appears when the fuel gauge IC on the original or a worn cell can no longer track actual cell voltage accurately under CPU and display load. At high draw, cell voltage sags below the BMS protection threshold before the OS percentage reaches zero, triggering an immediate cutoff. On a new cell, the same symptom in the first two cycles means the fuel gauge IC hasn't yet calibrated against the new chemistry. Run two full discharge-to-hibernate and charge-to-100% cycles — after that, the gauge IC recalibrates and the shutdowns stop. If the issue persists past three full cycles, check the BIOS battery report with the HP Support Assistant diagnostic; it will show the actual voltage at cutoff, which should read no lower than 10.8V under load.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43410864963674,"sku":"BWCS-HTB1200HB-1","price":77.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43410864996442,"sku":"BWCS-HTB1200HB-2","price":89.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43410865029210,"sku":"BWCS-HTB1200HB-3","price":99.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HTB1200HB-1.webp?v=1779581402","url":"https:\/\/batteryweb.com\/products\/hp-business-notebook-2210b-replacement-battery-144v-4400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
