It replaces OEM part SQU-1609 when the original cell degrades or fails to hold charge under load. Voltage, connector, and BMS communication lines match the factory spec for these models.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eXMG Core 15 and GK5CP6V compatibility:\u003c\/strong\u003e\n    Both the XMG Core 15 and GK5CP6V share the same 11.4V three-cell architecture, connector pinout, and BMS handshake protocol. One replacement covers both configurations — no adapter or firmware change needed.\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 XMG Core 15 platform. The BMS negotiated correctly with the EC firmware, reported accurate state-of-charge, and held voltage steady through CPU and GPU combined load spikes.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle calibration on XMG Core 15:\u003c\/strong\u003e\n    After installing, run one full discharge down to hibernate-cutoff, then charge uninterrupted to 100% without interruption. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears after every cell swap — it is not a fault.\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 SQU-1609\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe XMG Core 15 BIOS reads health data from an EEPROM register that the old cell wrote during its lifetime. A fresh cell arrives with different EEPROM values, so the BIOS flags it as degraded even though the capacity is full. This is a data mismatch, not a hardware fault. Running one complete discharge-to-hibernate followed by a full uninterrupted charge allows the EC to rewrite those registers against the new cell. After that cycle, health status returns to normal.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop shuts down at 20–30% charge shown on new battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the fuel gauge IC is still calibrated to the old cell's voltage curve. The new Li-Polymer cell has a steeper voltage cliff in the lower charge range, so the OS reads 25% when the cell is already near its cutoff threshold. The system shuts down to protect the cell before the gauge catches up. Complete two full discharge-charge cycles without interrupting charge, and the fuel gauge IC will remap its curve to the new cell's actual discharge profile. If it persists after two cycles, check that BIOS charge control is not set to a custom lower cutoff — reset it to 100% in the BIOS power settings.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409655857242,"sku":"BWCS-THX600NB-1","price":112.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409655890010,"sku":"BWCS-THX600NB-2","price":129.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409655922778,"sku":"BWCS-THX600NB-3","price":142.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-THX600NB-1.webp?v=1779580312","url":"https:\/\/batteryweb.com\/products\/schenker-xmg-core-15-replacement-battery-114v-7100mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
