It uses OEM part number HB466589EFW and fits model variants NTN-L22, NTN-LX1, and NTN-LX3. Swap this in when the original cell no longer holds charge, swells, or causes unexpected shutdowns.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eNTN-L22, NTN-LX1, NTN-LX3 variant fit:\u003c\/strong\u003e\n    All three NTN-series 50 Lite variants share the same battery bay dimensions and connector pinout. The BMS handshake runs on the same voltage rail across the lineup, so one cell covers all three regional builds.\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 the 50 Lite platform. The BMS accepted the cell without flagging an unrecognised battery warning, and the charge IC reached full termination voltage without interruption.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first use:\u003c\/strong\u003e\n    On first use after installation, disable fast charging and run one complete discharge-to-charge cycle. This lets the fuel gauge IC map the new cell's discharge curve before high-current charging pushes current into an uncalibrated cell.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Honor 50 Lite shuts down suddenly at 20–30% after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe 50 Lite's fuel gauge IC uses a coulomb counter calibrated to the original cell's discharge curve. A new cell has a different internal resistance profile, so the IC misjudges remaining charge and trips a low-voltage cutoff earlier than the percentage display suggests. Under modem or screen load, voltage sags past the cutoff threshold while the display still reads 25%. One full discharge cycle to 0% and a full charge to 100% resets the coulomb counter against the new cell's actual curve.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eUSB fast charge not activating on the first cycle after replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe 50 Lite's charge IC runs a handshake check on the first charge after a new cell is installed. If the BMS reports an uncalibrated state, the IC defaults to standard 5V charging and skips the fast-charge protocol entirely. This is a one-cycle protection behaviour, not a fault. Charge fully at standard rate once, then fast charging resumes normally on the next session.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43391804309594,"sku":"BWCS-HNR500SL-1","price":38.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43391804342362,"sku":"BWCS-HNR500SL-2","price":45.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43391804375130,"sku":"BWCS-HNR500SL-3","price":49.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HNR500SL-1.webp?v=1779142181","url":"https:\/\/batteryweb.com\/products\/honor-50-lite-replacement-battery-387v-4200mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
