It fits the G150MG-478G1T, G150P-47108G1TG8808G, G150TH, and over a dozen additional variants sharing the same battery bay and connector. Install it when the original cell no longer holds a useful charge or fails to charge at all.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eG150 series compatibility:\u003c\/strong\u003e\n    These models share a common battery bay geometry, 11.1V nominal rail, and the same BMS handshake protocol — which is why one cell covers the full G150 line 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 charge and discharge cycles on G150-series hardware. The BMS negotiated correctly, charge termination triggered at the expected cutoff, and the protection circuit responded to over-discharge conditions without tripping falsely under gaming load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration cycle:\u003c\/strong\u003e\n    After fitting this cell, run the laptop on battery power until it hibernates at low charge, 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 \"poor health\" warning that almost always appears after a 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 G150S shuts down at 20–30% after a battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe G150S uses a fuel gauge IC that stores learned voltage-to-capacity curves from the old cell. When a new cell goes in, those curves no longer match the actual chemistry. The BIOS reads voltage and incorrectly maps it to 20–30% remaining, then hits its shutdown threshold while the cell still has charge left. Running two or three full discharge-to-hibernate then full-charge cycles recalibrates the fuel gauge IC against the new cell's actual voltage profile.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBIOS reporting battery Wh rating as wrong after replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe system reads Wh data from the battery's EEPROM, which stores the manufacturer's rated figure. If the EEPROM value differs from what the BIOS expects, Windows or the firmware reports a mismatched Wh figure in system info. This is an EEPROM rated-versus-actual difference — not a fault with the cell itself. The battery charges and operates normally. Verify by checking actual charge voltage at the connector; it should read 12.6V at full charge.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409669029978,"sku":"BWCS-CLW650NB-1","price":75.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409669062746,"sku":"BWCS-CLW650NB-2","price":88.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409669095514,"sku":"BWCS-CLW650NB-3","price":97.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CLW650NB-1.webp?v=1779580338","url":"https:\/\/batteryweb.com\/products\/thunderobot-g150s-47104g500g9502g-replacement-battery-111v-4400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
