Battery Care Tips
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
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 LT23 Series — 11.1V Li-ion Replacement Battery (AL10A31)
This is an 11.1V, 4400mAh (48.84Wh) Li-ion battery for the Gateway LT23, LT2304c, LT2316u, LT2319u, and compatible models. It replaces the original AL10A31 and cross-referenced part numbers including AL10B31, AL10G31, and BT.00603.121. The connector pinout and BMS handshake match the LT23 charging circuit directly.
- LT23 series compatibility: These models share a common 11.1V battery bay, identical connector housing, and the same BMS communication protocol over the SMBus line — which is why one cell covers the full LT2304c through LT2319u range without hardware modification.
- Bench tested on actual hardware: We cycled this cell through the Gateway LT23 charging circuit and confirmed the BMS handshake completes correctly, charge current ramps as expected, and the protection IC triggers at both the high-voltage cutoff and the under-voltage floor without false trips.
- Post-install calibration on the LT23: After fitting this battery, run the laptop down to hibernate-cutoff on a real workload — not idle — then charge uninterrupted to 100%. The LT23 BIOS uses this cycle to re-learn cell capacity and clear the inaccurate health warning that appears after any cell swap.
Why the LT23 shuts down at 20–30% charge shown
The LT23 fuel gauge IC stores charge curve data from the previous cell in EEPROM. When a new cell goes in, the stored curve no longer matches actual cell chemistry, so the gauge reads 20–30% while the real cell voltage has already dropped below the load threshold. Under full CPU and display draw, voltage sags past the BMS cutoff floor before the gauge catches up. Running one full discharge-to-hibernate then a clean charge to 100% forces the fuel gauge to re-map against the new cell and eliminates the premature shutdown.
BIOS reporting battery health as poor or unknown after swap
The Gateway LT23 BIOS reads battery health from EEPROM data broadcast over SMBus — it is not measuring cell voltage directly. A replacement cell ships with default EEPROM values that differ from the aged cell's last-known state, which the BIOS flags as degraded or unrecognised. This is a data mismatch, not a fault with the new battery. Complete one full battery learn cycle — discharge to hibernate-cutoff, then charge to 100% without interruption — and the BIOS health status will update to normal.

Frequently Asked Questions
My Gateway LT23 shows the new battery as 0% or "unknown" in Windows — is it dead?
The fuel gauge IC is reading stale EEPROM data from the old cell, not the actual state of the new one. Windows and the BIOS both pull health data from that stored table rather than measuring the cell directly, so the display is wrong, not the battery. Discharge the laptop fully to hibernate-cutoff under a real workload, then charge uninterrupted to 100%. After that cycle, the gauge re-maps to the new cell and the percentage and health status report correctly.
The LT23 battery charge stops climbing around 80% and just sits there — what's blocking it?
Some Gateway LT23 BIOS versions include a charge-limit flag that caps charging at 80% to reduce cell stress during periods of prolonged AC use. This is firmware behaviour, not a battery fault. Enter the BIOS setup utility (F2 at boot), locate the battery or power management section, and disable the charge limit or battery care mode if present. If no such setting exists, the cell needs one full calibration cycle before the charge controller trusts it enough to allow a complete top-up.
The Wh rating in Windows Device Manager shows something different from the 48.84Wh on the listing — which is right?
Device Manager reads the rated Wh value stored in the cell's EEPROM, which can differ from the measured capacity of the actual chemistry inside. The 48.84Wh figure in the product data reflects the real energy capacity of this cell at 11.1V and 4400mAh. The EEPROM figure is a static value written at the factory and does not update when a new cell is installed. Run a full discharge-to-hibernate then charge-to-100% cycle — on some LT23 BIOS versions this triggers a re-read that brings the displayed Wh value closer to the actual spec.
