It replaces OEM part numbers 916TA013F and GNC-J40. Physical dimensions are 207.80 x 74.20 x 9.20mm — confirm clearance before ordering if the chassis has been modified.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eXMG C504 fitment:\u003c\/strong\u003e\n    The C504 uses a 15.2V four-cell Li-Polymer pack with a specific connector pinout tied to the EC (embedded controller) handshake. This battery matches that voltage rail and connector configuration so the EC recognises the pack and allows charging to proceed.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through charge, full discharge, and BMS cutoff verification. The protection circuit tripped at the correct low-voltage threshold and the BMS re-engaged cleanly on reconnection — no manual reset required.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration on the XMG C504:\u003c\/strong\u003e\n    After fitting, discharge the laptop fully until it hibernates on its own, then charge uninterrupted to 100% without use. This forces the BIOS battery learn cycle to complete against the new cell and clears the inaccurate health warning that appears 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\"\u003eBIOS reporting poor battery health immediately after fitting the new cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe XMG C504 BIOS reads EEPROM data embedded in the battery pack to estimate wear state. A brand-new cell has no cycle history written to that register yet, so the BIOS interprets the blank or mismatched data as a degraded pack. This is not a fault with the replacement cell. Run one full discharge-to-hibernate followed by an uninterrupted charge to 100% — the learn cycle writes fresh baseline data and the health warning clears on the next boot.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop shuts down abruptly at 25–30% charge shown on screen\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the fuel gauge IC hasn't calibrated against the new cell's actual voltage curve. The percentage reading drifts from reality, so the display shows 25% while the cell voltage has already hit the low-voltage cutoff threshold. The fix is two to three full discharge-and-charge cycles — each pass lets the fuel gauge IC re-map the voltage-to-capacity curve for the new cell. After those cycles, the cutoff should align with the displayed percentage and shutdowns at elevated charge levels stop.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409583833178,"sku":"BWCS-GTP345NB-1","price":80.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409583865946,"sku":"BWCS-GTP345NB-2","price":94.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409583898714,"sku":"BWCS-GTP345NB-3","price":105.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-GTP345NB-1.webp?v=1779580129","url":"https:\/\/batteryweb.com\/products\/schenker-xmg-c504-replacement-battery-152v-3950mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
