It cross-references OEM part numbers including 670953-851, 670954-851, HSTNN-W90C, HSTNN-UB3W, MI04, and MI06. If your 2170p no longer holds a charge or won't run off battery, this cell is the direct replacement.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eEliteBook 2170p platform fitment:\u003c\/strong\u003e\n    All listed OEM part numbers share the same 11.1V three-cell configuration, connector pinout, and BMS communication protocol used by the 2170p's EC firmware. Swapping between any of these part numbers does not require a firmware change.\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 the 2170p platform. The BMS handshake completed correctly, the EC firmware accepted the cell without error flags, and charge current tapered normally at the top of the charge curve.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-installation learn cycle on the 2170p:\u003c\/strong\u003e\n    After fitting the new cell, discharge the laptop to hibernate cutoff under normal use, then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning that commonly appears after a 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 2170p BIOS reads health data from the battery's EEPROM, which stores cycle count and rated capacity figures from the previous cell. When a new cell arrives, the EEPROM values don't yet match what the fuel gauge IC is measuring from actual charge cycles. The BIOS flags this mismatch as \"poor health\" or \"consider replacing.\" Running one full discharge-to-hibernate then a full uninterrupted charge resolves the mismatch by forcing the fuel gauge IC to recalibrate against the new cell's actual chemistry.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop shuts down at 20–30% battery shown on a new cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens because the fuel gauge IC still holds the old cell's voltage-to-capacity curve in memory. When the new cell hits its actual low-voltage knee — typically around 9.9–10.2V under CPU and display load — the laptop cuts off even though the OS gauge still shows charge remaining. The gauge hasn't yet mapped where this cell's voltage cliff sits. Two to three full discharge and charge cycles let the fuel gauge IC recalibrate the curve, and the shutdowns stop once the percentage readout tracks real cell voltage accurately.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409805574234,"sku":"BWCS-HP2170NB-1","price":75.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409805607002,"sku":"BWCS-HP2170NB-2","price":88.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409805639770,"sku":"BWCS-HP2170NB-3","price":99.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HP2170NB-1.webp?v=1779580992","url":"https:\/\/batteryweb.com\/products\/hp-elitebook-2170p-replacement-battery-111v-3700mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
