It replaces OEM part numbers 6-87-N550S-4E41, 6-87-N550S-4E43, 6-87-N550S-4E4, N550BAT-3, and 6-87-N550S-4E42. Physical dimensions are 250.40 × 85.70 × 8.20mm — confirm these against your existing cell before fitting.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eN551RC, N551RN, and N550RN compatibility:\u003c\/strong\u003e\n    These three models share the same battery bay dimensions, connector pinout, and BMS communication protocol. The same cell fits all three without modification. Check the sticker on your original battery for any of the part numbers listed above to confirm you have the right variant.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge-to-full, discharge-to-cutoff, and back-to-full cycles on the N551RC platform. The BMS handshake completed correctly, charge termination triggered at the expected voltage, and the protection circuit responded to over-discharge conditions without fault.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-installation conditioning for this platform:\u003c\/strong\u003e\n    After fitting, run one full discharge until the system hibernates at low battery, 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 series.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the N551RC shuts down at 20–30% battery remaining\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe fuel gauge IC on this platform was calibrated against the original cell's discharge curve. When a new cell is installed, the IC's stored data no longer matches the actual chemistry, so it miscalculates the remaining capacity. Under full CPU and display load, the laptop hits a voltage point the IC interprets as critical cutoff — even though the cell has charge left. Running two to three full discharge-and-charge cycles recalibrates the IC against the new cell and brings the gauge back into accurate range.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBIOS reporting battery health as \"poor\" immediately after replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe BIOS reads battery health data from EEPROM registers on the battery's BMS board. A fresh replacement cell carries factory-default EEPROM values that don't yet reflect real-world cycle data, and some BIOS firmware versions flag this as a health warning rather than a new-cell state. This is not a fault with the cell. Complete the learn cycle — discharge fully to hibernate, charge uninterrupted to 100% — and the BIOS health status will update once the EEPROM data populates correctly. If the warning persists beyond three cycles, check BIOS version against Clevo's firmware release notes for your model.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409564139610,"sku":"BWCS-CLN550NB-1","price":98.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409564172378,"sku":"BWCS-CLN550NB-2","price":116.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409564205146,"sku":"BWCS-CLN550NB-3","price":129.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CLN550NB-1.webp?v=1779580013","url":"https:\/\/batteryweb.com\/products\/clevo-n551rc-replacement-battery-114v-4000mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
