It matches the OEM part number NH50BAT-4 and fits the original battery bay without modification. Swap it in when the original cell no longer holds voltage under load or fails to register with the BIOS.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eG5 KC, G5 GD, and A7 X1 compatibility:\u003c\/strong\u003e\n    All three models share the NH50BAT-4 form factor, the same 14.4V nominal rail, and an identical BMS connector pinout. The BIOS on each recognises the cell by EEPROM handshake — this replacement carries matching EEPROM data so the firmware accepts it without throwing an unknown-device flag.\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 G5 platform. The BMS handshake completed without fault codes, charge current ramped correctly through CC and CV phases, and the fuel gauge IC began tracking state-of-charge accurately within two cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle calibration on the G5:\u003c\/strong\u003e\n    After fitting this battery, run one full discharge until the laptop hibernates, then charge uninterrupted to 100% without using the machine. This resets the BIOS battery learn cycle and clears the inaccurate health or low-capacity warning that appears after any cell swap on the G5 platform.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the G5 KC BIOS reports poor battery health immediately after a cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe G5 KC BIOS stores historical charge data from the previous cell in a battery learn table. When a new cell is installed, the BIOS compares the fresh EEPROM against its stored history and flags a mismatch as degraded health — even though the cell is new. This is not a fault with the replacement battery. Running one complete discharge-to-hibernate followed by an uninterrupted full charge clears the table and forces the firmware to rebuild its baseline from the new cell's actual chemistry.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eG5 KC shutting down at 20–30% battery shown on screen\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis symptom means the fuel gauge IC has not yet calibrated against the new cell's actual voltage curve. The gauge reports 20–30% remaining, but the cell voltage has already dropped below the BMS cutoff threshold under the combined load of the CPU, GPU, and display. The laptop shuts down to protect the cell — it is not a defective battery. Run two full discharge-to-hibernate and full recharge cycles; after the second cycle the fuel gauge IC recalibrates and the displayed percentage will align with actual cell voltage, with the shutdown point dropping to below 5%.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409593663578,"sku":"BWCS-CLH580NB-1","price":65.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409593696346,"sku":"BWCS-CLH580NB-2","price":77.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409593729114,"sku":"BWCS-CLH580NB-3","price":86.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CLH580NB-1.webp?v=1779580129","url":"https:\/\/batteryweb.com\/products\/gigabyte-g5-kc-replacement-battery-144v-2200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
