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 NV4900 / NV49C / NV59C Series — 11.1V Li-ion Replacement Battery (31CR19/652)

This is an 11.1V 4400mAh (48.84Wh) lithium-ion battery for the Gateway NV4900 and related NV-series laptops. It replaces OEM part numbers including 31CR19/652, AS10D31, AS10D41, AS10D51, AS10D61, AS10D71, AS10D3E, BT.00603.111, BT.00606.008, and BT.00607.125/127. It fits the NV4900, NV49C, NV49C13C, NV59C, and over 79 additional compatible models in the same platform family.

  • NV-series platform fit: Gateway's NV4900, NV49C, and NV59C lines share the same 11.1V battery rail, connector pinout, and BMS handshake protocol — that's why a single cell covers this many models across the NV range.
  • Bench tested on actual hardware: We ran this cell through full charge and load cycles on NV-series hardware. The BMS communicated correctly with the system, charge current was accepted without interruption, and voltage held steady under combined CPU and display load through to low-cell cutoff.
  • Post-install recalibration on Gateway NV hardware: After fitting this cell, 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.

Why the NV4900 shuts down at 20–30% remaining after a battery swap

This happens because the BIOS fuel gauge IC still holds calibration data from the old, degraded cell. It models the new cell's discharge curve against those old reference points and calls the voltage cliff too early. Under combined CPU and display load, the voltage drop looks like a dead cell to the BIOS — even though capacity remains. Run a full discharge-to-hibernate followed by an uninterrupted charge to 100% to force the fuel gauge IC to re-map the actual voltage curve of the new cell. After two to three of these calibration cycles, the reported percentage at shutdown should move back down to the 3–5% range.

BIOS reporting 0% or "unknown" battery after fitting the new cell

The BIOS reads battery identity and health data from the cell's EEPROM on first contact. If the old cell's EEPROM data is still cached — or the new cell hasn't completed a handshake cycle — Windows and the Gateway BIOS will show 0%, "plugged in, not charging," or an unknown device flag. Unplug the AC adapter, hold the power button for 15 seconds to drain the board caps, then reconnect and power on. This forces a fresh EEPROM read and clears the cached identity from the previous cell.

Frequently Asked Questions

My Gateway NV4900 shows the wrong Wh rating in system info after I fitted this battery — is something wrong with the cell?

No fault with the cell. The Wh figure shown in Windows Device Manager or BIOS pulls from the EEPROM data embedded in the battery controller, which stores the rated chemistry spec rather than a live measured value. There can be a small difference between the EEPROM-declared Wh and the actual cell chemistry in a third-party replacement. This is a data mismatch, not a capacity fault — charge the battery to 100%, then check the reported full-charge capacity in milliwatt-hours using HWiNFO or BatteryInfoView for the accurate figure.

The fuel gauge on my NV49C jumps around wildly — showing 60%, then 45%, then back to 55% within minutes of unplugging. What's going on?

The fuel gauge IC on Gateway NV-series laptops needs two to three full discharge-and-recharge cycles to build an accurate model of the new cell's voltage-to-capacity curve. Until those cycles are complete, the IC is interpolating against stale data from the old cell and the readings will be erratic. Run a full discharge to hibernate-cutoff, then charge uninterrupted to 100% — repeat this twice. After the third full cycle the gauge should stabilise to within a few percent.

My NV59C charges fine but the battery health shows "poor" or "replace" in the Gateway power utility right after installing this new cell — should I return it?

That warning comes from the BIOS battery learn cycle comparing the new cell's EEPROM against the health thresholds set for the original factory cell. The BIOS has no way to know the old data is stale until it observes a full charge-discharge cycle on the new cell. Do not return it. Discharge the laptop fully to hibernate, then charge uninterrupted to 100%. Check the power utility again — the health status should update to normal once the BIOS has logged one complete cycle against the new cell's actual voltage range.
