It replaces OEM parts 4UR18650-2-7, F1753-60978, F1739A, and F1739B. Fit applies to both Solo models sharing this voltage rail and connector configuration.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSolo 1100 and 1150 compatibility:\u003c\/strong\u003e\n    Both models run the same 14.8V four-cell Li-ion architecture with an identical BMS handshake protocol and connector pinout — one cell covers both 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 load cycles on a Solo 1100 unit. The BMS communicated charge status correctly, cell balancing engaged as expected, and the protection circuit tripped cleanly at the low-voltage cutoff threshold.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eSolo 1100 calibration cycle:\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 after every cell swap on this platform.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSolo 1100 BIOS reporting poor battery health after cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Solo 1100 BIOS reads health data stored in the old cell's EEPROM. When a new cell arrives, the BIOS compares its embedded data against the previous cell's logged cycle count and rated capacity — finding no match, it flags the battery as poor or unknown. This is not a fault with the new cell. Running a full discharge-to-hibernate followed by a complete charge allows the BIOS to complete its learn cycle and write fresh health data to the new cell's EEPROM.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSolo 1100 shutting down at 20–30% charge remaining\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the fuel gauge IC has not yet calibrated against the new cell's actual charge curve. The gauge IC was trained on the old, degraded cell and misjudges the new cell's remaining voltage. Under full CPU and display load, the laptop hits a voltage threshold the gauge reads as empty — even though charge remains. Two to three full discharge-and-charge cycles recalibrate the IC against the new chemistry. After calibration, the shutoff point should align with an actual cell voltage of approximately 11.1V.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43410855297114,"sku":"BWCS-HXE2-1","price":66.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43410855329882,"sku":"BWCS-HXE2-2","price":78.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43410855362650,"sku":"BWCS-HXE2-3","price":87.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HXE2-big.webp?v=1779581376","url":"https:\/\/batteryweb.com\/products\/gateway-solo-1100-replacement-battery-148v-4400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
