It replaces OEM part numbers C41N1837 and 0B200-03380100. If your original cell has swollen, dropped capacity, or no longer holds a charge under GPU load, this cell fits the same bay with no modification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eZephyrus and ROG series fit:\u003c\/strong\u003e\n    The GX532GV, GA502IU, GX502LXS, and GU502GV all share the same 4-cell Li-Polymer bay, 15.4V nominal rail, and BMS handshake tied to the C41N1837 EEPROM signature. That shared architecture is why one cell covers 100+ model variants across those sub-lines.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell on a GX532GV under combined CPU and GPU load. The BMS held the charge curve correctly through full cycles, and the ACPI charge status reported accurately once the BIOS learn cycle completed after the first full discharge.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration on Zephyrus hardware:\u003c\/strong\u003e\n    After fitting this cell, let the laptop discharge fully to hibernate cutoff — do not interrupt it — then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears in MyASUS after every cell swap.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the GX532GV BIOS reports poor battery health after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Asus BIOS reads health data from the EEPROM on the battery's BMS board, not from live voltage measurements. When you install a new cell, the EEPROM carries factory-default charge cycle data that the BIOS interprets as a degraded or unknown battery. This triggers the \"poor health\" or \"battery not detected\" warning in MyASUS and the BIOS hardware monitor. Running one complete discharge-to-hibernate followed by an uninterrupted full charge forces the BIOS to rewrite its internal battery profile against the new cell. After one to two calibration cycles, the health indicator returns to normal.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eGX532GV shutting down at 20–30% charge shown on screen\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a voltage cliff — the cell voltage drops sharply under the combined draw of the CPU, GPU, and display before the fuel gauge IC registers empty. The fuel gauge IC estimates remaining charge based on a capacity model it built against the old cell, so its percentage reading lags behind actual cell voltage. The fix is a full calibration cycle: drain the laptop to automatic hibernate, then charge to 100% with no interruptions. After two cycles, the fuel gauge IC recalibrates its model to the new cell's actual discharge curve and the early shutdowns stop.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409625022554,"sku":"BWCS-AUX532NB-1","price":109.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409625055322,"sku":"BWCS-AUX532NB-2","price":125.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409625088090,"sku":"BWCS-AUX532NB-3","price":138.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-AUX532NB-1.webp?v=1779580296","url":"https:\/\/batteryweb.com\/products\/asus-gx532gv-replacement-battery-154v-4800mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
