from 12 reviews

I'm writing this review to express my deep gratitude and appreciation for the quality of services provided to me by the BatteryWeb service team. I visited BatteryWeb to purchase a replacement battery for my Remington R9 razor. The staff was very responsive and I was really impressed with their willingness to help me and make the purchasing process as quick as possible. In particular I greatly appreciate the work of staff member Shane who was friendly and helpful.
In conclusion, I believe that BatteryWeb has excellent service staff who make their customers feel honored and valued.
I wish you all the best.
Sincerely,
Michael

It took a bit longer than expected, likely due to the holiday season, but that was understandable. So far, the battery seems to be working well!

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 2300 Series — 14.8V Li-ion Replacement Battery (1507480)

This is a 14.8V, 4400mAh (65.12Wh) Li-ion battery for the Gateway Solo 2300, Solo 2500, Solo 9100, and Solo 9150 notebook computers. It replaces OEM part numbers 1507480, 6500099, 6500190, 6500332, and PWCBTY020AAWW. Install it when the original cell no longer holds charge or the laptop won't run off battery at all.

  • Solo 2300 / 2500 / 9100 / 9150 compatibility: All four models share the same 14.8V battery rail, connector pinout, and BMS handshake protocol — one cell fits the entire platform without modification or adapters.
  • Bench tested on actual hardware: We cycled this battery through charge and discharge on Gateway Solo hardware. The BMS engaged correctly at both low-voltage cutoff and charge termination, with no false trips or runaway charge events recorded.
  • First-cycle reset after install: After fitting this battery, run the laptop on battery power until it hibernates at low-charge cutoff, then charge uninterrupted to 100%. This forces the BIOS to complete a battery learn cycle and clears the inaccurate health warning that appears after every cell swap on these models.

BIOS reporting poor battery health immediately after replacement

The Gateway Solo BIOS reads health data from EEPROM registers written by the original factory cell. When a new cell is installed, those registers contain stale data that doesn't match the new chemistry, so the BIOS flags it as degraded. This is a data mismatch, not a cell fault. Run one full discharge-to-hibernate followed by an uninterrupted full charge. After one or two complete cycles, the BIOS battery learn cycle overwrites the old EEPROM values and the health warning clears.

Laptop shuts down hard at 20–30% charge shown on screen

This happens when the fuel gauge IC has not yet calibrated against the new cell's actual voltage curve. The gauge estimates remaining charge based on the old cell's discharge profile, so it reads 25% while the actual cell voltage is already near cutoff. Under full CPU and display load, the voltage cliff hits faster than the gauge expects, and the system shuts down without warning. Run two full discharge-to-hibernate and uninterrupted charge cycles to let the fuel gauge IC re-map the voltage curve — after calibration, the shutdown threshold should stabilise below 5% shown.

Frequently Asked Questions

The Gateway Solo shows the new battery as "unknown" or 0% in Windows — is the cell faulty?

The cell is almost certainly fine. The fuel gauge IC in the Solo uses EEPROM data from the old battery to estimate charge state, and on a fresh cell that data doesn't match yet. Run one full discharge until the laptop hibernates at low-voltage cutoff, then charge uninterrupted to 100%. After one complete cycle the fuel gauge re-maps to the new cell and the percentage reads correctly.

Windows and the BIOS are showing this battery's capacity as a different Wh rating than what's listed on the label — which number is right?

The Wh figure the system reports is pulled from the EEPROM registers, which were written at the factory based on the original cell's rated chemistry. The physical label and product data reflect the actual measured capacity of this replacement cell at 65.12Wh. The two numbers can differ without any fault on either side. After two full calibration cycles the system-reported figure will converge closer to the actual cell capacity as the BMS updates its calculations.

The Solo 2300 charges to 100% fine but the battery drains far faster than expected on the new cell — what's causing that?

If charge reaches 100% and holds, the cell itself is working. Fast drain on these Gateway models is usually a calibration gap — the fuel gauge IC was trained on a worn original cell that had low actual capacity, so it underestimates how hard it's working against a full-capacity new cell. It corrects itself through use. Run three full discharge-to-hibernate cycles with no partial top-ups in between, then monitor drain rate. By the third cycle the gauge should be tracking the new cell's actual discharge curve accurately.
