It replaces OEM part numbers 1527196, 1528266, SQU-203, and the 3UR18650F-2-QC series cells among others. Voltage and capacity match OEM spec: 14.8V nominal, 65.12Wh.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSolo 400\/450 series compatibility:\u003c\/strong\u003e\n    These models share the same 4-cell 14.8V battery bay, connector pinout, and BMS communication protocol — which is why a single SKU covers 400VTX through the broader 450 lineup. The cells are wired in a 4S2P configuration; the BMS handshake runs over the same SMBus line across every variant in this range.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell against the Solo 450 platform and confirmed the BMS completed full charge negotiation, reported state-of-charge correctly over SMBus, and held voltage above the 11V cutoff threshold under sustained CPU and display load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle conditioning on the Solo 400\/450:\u003c\/strong\u003e\n    After installing, run one full discharge to hibernate-cutoff, then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears on the first boot with a new cell — skipping this step often leaves the OS fuel gauge reading 0% or \"unknown\" for several sessions.\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 fitting a new cell\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Solo series stores battery health history in EEPROM on the original cell's BMS board. When a new cell goes in, the BIOS reads that data as absent or mismatched and flags the battery as degraded or unknown — even though the cell is fresh. This is a data mismatch, not a hardware fault. Running a full discharge-to-hibernate followed by a clean charge to 100% forces the BIOS to rebuild its learned capacity table against the new cell's actual chemistry, and the health warning clears within one to two full cycles.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop shuts down abruptly at 20–30% remaining on the gauge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a voltage cliff, not a gauge error. Under full CPU and backlight load, the cells drop voltage faster than the fuel gauge IC tracks — the system hits the low-voltage cutoff while the displayed percentage still reads 20–30%. It happens most often on aging laptops where the BIOS learned curve was built against a depleted original cell. The fix is a calibration cycle: discharge the laptop to automatic hibernate under normal use load, then charge to 100% without interruption. After two to three cycles the fuel gauge IC recalibrates against the new cell's actual voltage curve and the early shutdowns stop.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43410831802458,"sku":"BWCS-GW450NB-1","price":74.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43410831835226,"sku":"BWCS-GW450NB-2","price":86.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43410831867994,"sku":"BWCS-GW450NB-3","price":95.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-GW450NB-1.webp?v=1779581286","url":"https:\/\/batteryweb.com\/products\/gateway-solo-400vtx-replacement-battery-148v-4400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
