It replaces the original cell when the laptop no longer holds charge or fails to power on from battery. Voltage, connector, and BMS signalling match the original specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eXMG U500 and U700 series compatibility:\u003c\/strong\u003e\n    These models share a 14.8V four-cell architecture, the same physical connector, and a common BMS communication protocol. A single replacement cell covers the full range without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through a full charge and discharge cycle on XMG U505 hardware. The BMS handshake completed correctly, charge accepted to capacity, and the protection circuit responded appropriately at low-voltage cutoff.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration on XMG systems:\u003c\/strong\u003e\n    After fitting, run the laptop on battery until it hibernates at cutoff, then charge uninterrupted to 100% without powering on mid-cycle. This forces the BIOS battery learn cycle to reset 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 battery health as poor immediately after fitting\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eXMG laptops store battery health data in EEPROM on the old cell. When a new cell is installed, the BIOS reads no prior charge history and flags health as unknown or poor. This is a data state, not a hardware fault. Running one complete discharge-to-hibernate followed by a full uninterrupted charge gives the BIOS enough cycle data to recalculate health correctly. After two to three full cycles, the health indicator typically clears to normal.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop cutting out at 20–30% shown on the OS fuel gauge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe fuel gauge IC calibrates against the old cell's discharge curve. After a swap, the stored curve no longer matches the new cell, so the reported percentage drifts from actual voltage. Under full CPU and display load, the real cell voltage drops below the BMS cutoff threshold while the gauge still shows 20–30% remaining. Run two full discharge-to-hibernate cycles to let the fuel gauge IC recalibrate against the new cell's actual curve. If cutoff still occurs early, check that the cell resting voltage reads at least 14.4V after a full charge.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409748852826,"sku":"BWCS-CLP750NB-1","price":110.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409748885594,"sku":"BWCS-CLP750NB-2","price":125.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409748918362,"sku":"BWCS-CLP750NB-3","price":137.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CLP750NB-1.webp?v=1779580646","url":"https:\/\/batteryweb.com\/products\/schenker-xmg-u505-replacement-battery-148v-4400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
