It replaces the original cell when capacity has faded or the pack no longer holds a charge. Voltage, connector, and physical dimensions match the factory specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eXMG U727 and U726 fitment:\u003c\/strong\u003e\n    Both models run the same 15.12V four-cell series configuration with an identical connector pinout and BMS communication protocol. One battery covers both platforms without modification.\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 a compatible XMG platform. The BMS handshake completed without fault, charge current stepped down correctly at the 80% and 95% thresholds, and cutoff voltage held at the rated floor under sustained CPU and GPU load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration for XMG U727:\u003c\/strong\u003e\n    After fitting this battery, run one full discharge to the hibernate cutoff — do not interrupt it — then charge uninterrupted to 100%. This forces the BIOS battery learn cycle to reset against the new cell's actual capacity 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 a new cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe XMG U727 BIOS reads health data stored in the old cell's EEPROM and compares it against the new cell's reported capacity. Because the new pack has no charge history, the BIOS flags it as degraded or unknown. This is not a fault with the replacement cell. Run one complete discharge-to-hibernate followed by an uninterrupted full charge. After two to three cycles, the fuel gauge IC recalibrates and the health indicator returns to normal.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop shutting down at 20–30% charge shown on screen\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eUnder sustained GPU render or CPU boost, the U727 draws peak current that the degraded original cell could not sustain — the cell voltage collapses below the BMS cutoff threshold before the fuel gauge reaches zero. If this happens with a new replacement cell, the fuel gauge IC has not yet calibrated to the new chemistry. Run the full discharge-to-hibernate cycle described above. After calibration, the reported percentage at shutdown should align closely with the actual remaining cell voltage, typically above 3.0V per cell under load.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409679024218,"sku":"BWCS-CLP870NB-1","price":98.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409679056986,"sku":"BWCS-CLP870NB-2","price":115.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409679089754,"sku":"BWCS-CLP870NB-3","price":128.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CLP870NB-1.webp?v=1779580399","url":"https:\/\/batteryweb.com\/products\/schenker-xmg-u727-replacement-battery-1512v-5800mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
