It fits the MSI GS70 Stealth Pro gaming notebook line, including the 2PE, 2QE, 2QD, and 2PC variants. Swap it in when the original cell no longer holds charge under gaming or high-load use.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eGS70 series compatibility:\u003c\/strong\u003e\n    All GS70 variants on the BTY-L76 platform share the same 11.4V three-cell configuration, connector pinout, and BMS handshake protocol. The same cell works across 2PE, 2QE, 2QD, and 2PC boards 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 full charge and discharge cycles on a GS70 board. The BMS communicated correctly, charge termination triggered at the right voltage, and the protection circuit responded normally to load spikes from the GPU.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle reset after install:\u003c\/strong\u003e\n    After fitting the new cell, run one full discharge down to hibernate cutoff, then charge uninterrupted to 100%. This clears the BIOS battery learn cycle data carried over from the old cell and removes 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\"\u003eWhy the GS70 shuts down at 20–30% shown after a battery swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe GS70's fuel gauge IC calibrates its empty-cell voltage threshold against the old battery's internal resistance profile. With a new cell, that threshold no longer matches actual chemistry behaviour. Under combined CPU and GPU load, the new cell's voltage drops faster than the IC expects, triggering a shutdown before the display percentage reaches zero. Running two full discharge-to-hibernate and charge-to-100% cycles recalibrates the IC against the new cell's actual voltage curve. After calibration, the shutdown threshold realigns and the gauge tracks correctly.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBIOS showing 0% or \"unknown\" battery immediately after fitting the new cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe BIOS reads battery identity and health data from the cell's EEPROM, not from a live voltage measurement. When a replacement cell arrives, its EEPROM data does not match the wear history the BIOS logged for the original pack. This mismatch causes the system to report 0%, \"consider replacing,\" or \"unknown\" on first boot. Boot into BIOS, let the battery reach at least 11.7V under charge, then run a full battery learn cycle from the EC firmware. The warning clears once the controller writes fresh baseline data to match the new cell.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409725816922,"sku":"BWCS-MRS700NB-1","price":113.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409725849690,"sku":"BWCS-MRS700NB-2","price":129.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409725882458,"sku":"BWCS-MRS700NB-3","price":141.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MRS700NB-1.webp?v=1779580558","url":"https:\/\/batteryweb.com\/products\/msi-gs70-2pe-026cn-replacement-battery-114v-5400mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
