It replaces OEM part numbers BTY-S14 and BTY-S15, among others listed. Capacity is 48.84Wh — matching the original cell specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCR650 \/ CX650 \/ FR400 \/ FX400 platform fit:\u003c\/strong\u003e\n    These models share the same 11.1V three-cell battery rail, connector pinout, and BMS handshake protocol. One cell covers the entire group — no adapter or modification needed.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge and discharge cycles on an MSI CR650 unit. The BMS accepted the cell without fault codes, charge negotiation completed normally, and the protection circuit tripped correctly at low-voltage cutoff.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration on MSI notebooks:\u003c\/strong\u003e\n    After fitting this battery, run the laptop down to hibernate-cutoff under normal use, then charge uninterrupted to 100%. This forces the BIOS battery learn cycle to reset against the new cell's actual capacity and clears the false 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 installation\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe MSI BIOS reads health data from the battery's EEPROM, which stores charge cycle count and rated capacity from the previous cell. A brand-new cell arrives with EEPROM values the BIOS doesn't recognise as matching its stored baseline, so it flags health as poor or unknown. This is a firmware calibration issue, not a fault with the replacement cell. One full discharge-to-hibernate followed by an uninterrupted charge to 100% resets the learn cycle. After two to three cycles the BIOS health reading normalises.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop shuts down abruptly at 20–30% charge shown on screen\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a voltage cliff issue. Under combined CPU and display load, the cell voltage drops faster than the fuel gauge IC can track, and the system hits the low-voltage protection threshold before the displayed percentage reaches zero. It typically means the fuel gauge IC has not yet calibrated its discharge curve against the new cell's actual chemistry. Run two full discharge cycles — down to automatic hibernate, not a forced shutdown — then charge to 100% each time. The gauge recalibrates its curve and the cutoff point shifts back toward 5–10% where it belongs.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409813143642,"sku":"BWCS-MSX400NB-1","price":69.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409813176410,"sku":"BWCS-MSX400NB-2","price":81.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409813209178,"sku":"BWCS-MSX400NB-3","price":89.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MSX400NB-1.webp?v=1779581059","url":"https:\/\/batteryweb.com\/products\/msi-cr650-replacement-battery-111v-4400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
