Dell Latitude X1 Replacement Battery 11.1V 2200mAh 312-0341

Up to 19% off
New arrival
From $61.99 USD $76.99
Shipping calculated at checkout.
Fits Dell Latitude X1 ultraportable notebooks; replaces OEM part numbers 312-0341, Y6457, T6840, U6256, 312-0342, and X6753.
Delivers 11.1V at 2200mAh capacity, storing 24.42Wh total — sufficient for unplugged operation on this early-2000s business system.
Connector slides onto the battery slot with a positive locking tab; orientation is keyed, so reversal is physically impossible.
We bench-tested against a known-good Latitude X1 unit; the BMS accepted charge current on first insertion with 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 the inaccurate health warning that appears after every cell swap.

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.

Dell Latitude X1 — 11.1V Li-ion Replacement Battery (312-0341)

This is an 11.1V, 2200mAh (24.42Wh) Li-ion battery for the Dell Latitude X1 ultraportable notebook. It replaces OEM part numbers 312-0341, Y6457, T6840, U6256, 312-0342, and X6753. If the original cell no longer holds a charge or the system won't run unplugged, this is the direct swap.

  • Latitude X1 fitment: All six OEM part numbers above cross-reference to the same battery bay, connector pinout, and BMS handshake on the Latitude X1 motherboard. Dell used multiple supplier codes across production runs — the electrical spec is identical across all variants.
  • Bench tested on actual hardware: We ran this cell through full charge and load cycles on a Latitude X1 unit. The BMS communicated correctly with the system, charge accepted without error, and the fuel gauge IC registered current and voltage within expected range.
  • BIOS learn cycle after install: After fitting this battery, run the laptop down to hibernate-cutoff under normal use, then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning the system throws after any cell swap.

Why the Latitude X1 shuts down at 20–30% after a battery swap

The Latitude X1 BIOS stores discharge curve data from the previous cell. When a new cell is installed, that stored curve no longer matches actual voltage behaviour. At around 20–30% shown, the new cell hits a voltage cliff under combined CPU and display load that the old calibration data doesn't anticipate. The BIOS cuts power before the fuel gauge reaches zero because the voltage drop looks like a fault. Run two full discharge-to-hibernate then full-charge cycles and the BIOS recalibrates against the new cell's actual curve.

BIOS reporting 0% or "unknown" battery immediately after fitting

The fuel gauge IC on the Latitude X1 reads EEPROM data embedded in the battery pack to identify cell capacity and state of charge. A freshly installed cell presents EEPROM values the IC hasn't seen before, so it defaults to 0% or flags the battery as unknown. This is not a fault with the battery or the laptop. Boot into Windows, confirm AC adapter is connected, then let the battery charge to 100% uninterrupted — the IC will initialise against the new EEPROM data. After one full discharge-recharge cycle, the gauge should read accurately. Target 11.1V at full charge as your confirmation point.

Frequently Asked Questions

My Latitude X1 shows the correct percentage for a few cycles then starts jumping around wildly — is the new battery defective?

The fuel gauge IC needs several full charge and discharge cycles to map its internal model against the new cell's actual chemistry. Until that calibration settles, the percentage reading can skip or drift significantly. Run two complete discharge-to-hibernate then uninterrupted full-charge cycles without pulling the AC adapter mid-charge. After the second cycle the gauge IC stabilises and readings become consistent.

The Latitude X1 BIOS reports a much lower Wh rating than the 24.42Wh on the product listing — which number is correct?

The Wh figure the BIOS reads comes from EEPROM data written by the original cell manufacturer, which sometimes reflects a rated nominal value rather than actual measured capacity. The 24.42Wh figure in the product listing is calculated directly from the cell's voltage and measured capacity — 11.1V multiplied by 2200mAh. The BIOS display is informational only and a mismatch here does not affect how the battery charges or discharges. Confirm the cell is accepted by the system and charging normally — that is the functional check that matters.

New battery installed but the Latitude X1 won't charge above 80% — is something wrong with the cell?

Dell's BIOS on several Latitude-series notebooks includes a charge-limit setting that caps charging at 80% to reduce cell stress during extended AC use. This is a firmware control, not a battery fault. Open Dell ControlVault or check BIOS under Power Management for a setting labelled "Battery Charge Configuration" or "Primarily AC" mode. Switch to "Standard" or "Express Charge" and cycle the power — the battery will then charge to 100%.
