4UR18650-2-7 Gateway Solo 1100 Replacement Battery 14.8V

Up to 19% off
New arrival
From $66.99 USD $82.99
Shipping calculated at checkout.
Fits Gateway Solo 1100 and Solo 1150 laptops, replacing OEM part numbers 4UR18650-2-7, F1753-60978, F1739A, and F1739B.
14.8V and 4400mAh capacity restore full portable runtime on the Solo platform without AC adapter dependency.
Connector slides straight into the battery bay slot with positive terminal facing upward and locking tab engagement on the right side.
We bench-tested this cell on a Solo 1100 motherboard; the BMS accepted the pack on first insertion with clean voltage handshake and no fault codes.
After installation, run one full discharge to hibernation cutoff then charge uninterrupted to 100% — this resets the BIOS battery learn cycle and clears health warnings that appear after every cell swap.

Battery Care Tips

🔹 Getting Started

Charge your new battery fully before you use it for the first time. Over the next few charge cycles, run your device down to around 20% before you recharge—this helps the battery perform its best. After that, charge whenever you need to.

🔹 Keep It Healthy

Avoid letting your battery completely drain or staying plugged in constantly. Both extremes wear it out faster. Store the battery in a cool, dry place when you're not using it, since heat damages batteries quickly.

Delivery and Shipping

🔹 Most orders ship the next day, and we use FedEx, UPS, Purolator and other carriers to get them to you. Lithium batteries have to ship by ground only, not air or USPS. Make sure your address is right before you order, because if we have to send it back, you pay for shipping again.

Gateway Solo 1100 / Solo 1150 — 14.8V Li-ion Replacement Battery (4UR18650-2-7)

This is a 14.8V, 4400mAh (65.12Wh) Li-ion battery for the Gateway Solo 1100 and Solo 1150 notebook computers. 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.

  • Solo 1100 and 1150 compatibility: 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.
  • Bench tested on actual hardware: 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.
  • Solo 1100 calibration cycle: 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.

Solo 1100 BIOS reporting poor battery health after cell swap

The 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.

Solo 1100 shutting down at 20–30% charge remaining

This 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.

Frequently Asked Questions

My Solo 1100 BIOS shows the new battery as "0% available (plugged in, charging)" and won't move — what's going on?

The BIOS fuel gauge IC is still reading EEPROM data from the old cell and has no valid baseline for the new one. Discharge the laptop fully until it hibernates, then charge uninterrupted to 100% without interruption. This forces the BIOS learn cycle to run completely and write new reference data to the cell's EEPROM. After one full cycle the percentage reading should update correctly.

Windows shows this battery at 48Wh but the spec says 65Wh — is the cell underrated or faulty?

The Wh figure Windows reports pulls from EEPROM data embedded in the cell, which reflects the rated capacity at manufacture under controlled conditions. The fuel gauge IC hasn't yet mapped actual charge throughput against the new cell, so the reported Wh reads low until calibration cycles complete. Run two to three full discharge-and-charge cycles and the reported Wh value will converge toward the actual 65.12Wh rating. No hardware fault — this is a data alignment issue, not a capacity issue.

The Solo 1150 stops charging at around 80% and sits there — is the charger the problem?

This is almost always a BIOS-controlled charge threshold, not a charger fault and not a cell fault. Some Gateway BIOS versions on the Solo platform include a charge-limit setting that caps cells at 80% to reduce cell stress during extended AC use. Check the BIOS power management menu under the battery settings section and confirm the charge limit is set to 100%. If no BIOS setting is present, a full discharge-to-hibernate followed by a fresh charge cycle will clear any stuck charge-state flag.
