It replaces OEM part numbers including EH768UT, 484784-001, HSTNN-DB23, and HSTNN-DB22, among others. The cell fits the standard battery bay and connects through the same multi-pin interface as the original pack.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003enc2400, 2400, and 2510p compatibility:\u003c\/strong\u003e\n    These three models share the same 10.8V battery rail, connector pinout, and BMS communication protocol. One cell covers all three without any 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 nc2400 and monitored the BMS handshake through full charge and discharge cycles. The protection circuit responded correctly to overcurrent, over-voltage, and thermal events at each stage.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle calibration on the nc2400:\u003c\/strong\u003e\n    After installing this battery, run a full discharge to the hibernate cutoff, then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears after a cell swap.\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 after installing this cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe nc2400 BIOS stores battery health data in EEPROM and compares it against readings from the previous cell. When a new cell is installed, the EEPROM data no longer matches the actual cell state, so the BIOS flags it as degraded. This is not a fault with the replacement battery. Running a full discharge-to-hibernate followed by an uninterrupted charge to 100% triggers the BIOS learn cycle, which rewrites the EEPROM reference values against the new cell. After one or two completed cycles, the health indicator will update to reflect the actual cell condition.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003enc2400 shutting down at 20–30% charge shown on the gauge\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 over-reports remaining capacity, and when the real cell voltage drops below the safe threshold under CPU and display load, the laptop cuts out before the display reaches 0%. The fix is to complete two or three full discharge-to-hibernate and full-charge cycles without interrupting the charge. After calibration, the gauge tracks the voltage cliff accurately and the premature shutdowns stop. Confirm the cell voltage reads at least 10.4V under load before trusting the gauge percentage.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43410821939290,"sku":"BWCS-CP2400HB-1","price":117.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43410821972058,"sku":"BWCS-CP2400HB-2","price":134.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43410822004826,"sku":"BWCS-CP2400HB-3","price":147.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CP2400HB-1.webp?v=1779581242","url":"https:\/\/batteryweb.com\/products\/compaq-business-notebook-nc2400-replacement-battery-108v-6600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
