Fits Dell Latitude E6120, E6220, E6230, E6320 and replaces OEM part 9GXD5.
11.1V and 6600mAh (73.26Wh) restores full charge capacity on the original pack.
Connector slides straight into the battery slot with a single locking tab engagement.
We ran full charge-discharge cycles; the BMS stabilized voltage delivery under sustained CPU load.
After installation, discharge fully to hibernation then charge uninterrupted to 100% — this resets the BIOS battery learn cycle and clears false health warnings that appear after every cell swap.

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,

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 E6120 / E6220 / E6320 Series — 11.1V Li-ion Replacement Battery (9GXD5)

This is an 11.1V 6600mAh (73.26Wh) lithium-ion battery for the Dell Latitude E6120, E6220, E6230, and E6320 series notebooks. It replaces OEM part numbers including 9GXD5, R8R6F, RFJMW, and YJNKK, among others. The battery connects via the standard Dell 9-cell connector used across this Latitude generation.

  • E6120 / E6220 / E6230 / E6320 compatibility: These four models share the same battery bay dimensions, connector pinout, and BMS handshake protocol. Dell standardised the 11.1V rail and EEPROM authentication across this Latitude generation, so one cell fits all four without adapter or firmware changes.
  • Bench tested on actual hardware: We cycled this battery on an E6220 and an E6320 under combined CPU and display load. The BMS held voltage above the 10.5V cutoff through full discharge, and charge termination triggered correctly at capacity without false short-circuit trips.
  • Post-install calibration on Dell Latitude: After fitting this battery, run the system down to hibernate-cutoff on a live workload, then charge uninterrupted to 100% without sleep interruptions. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears after every cell swap on this platform.

BIOS reporting battery health as poor immediately after replacement

The Latitude BIOS reads health data from the EEPROM embedded in the battery pack, not from live cell voltage. When a new cell is installed, the EEPROM data does not match the charge history the BIOS expects from the old pack, so it flags health as poor or unknown. This is a data mismatch, not a cell fault. Running one full discharge-to-hibernate followed by an uninterrupted charge to 100% allows the BIOS learn cycle to rewrite its reference data against the new cell and clear the warning.

Laptop shutting down at 20–30% shown on the fuel gauge

The fuel gauge IC on this platform calibrates its discharge curve against the original cell's internal resistance profile. After a cell swap, the IC underestimates remaining capacity because it is still using the old cell's resistance map. At high combined loads — full CPU plus display brightness — the new cell hits a voltage cliff the IC predicts at the wrong state of charge, triggering shutdown. Run two full discharge-to-hibernate cycles under normal workload to let the fuel gauge IC recalibrate. After the second full cycle, shutdown should not occur above 10–12% shown, with cell voltage staying above 10.5V at that point.

Frequently Asked Questions

Dell BIOS shows "Battery health: poor" right after I installed the new battery — is the cell dead already?

No — the BIOS is reading EEPROM data that doesn't match the new cell's charge history, not actual cell condition. This mismatch triggers the health warning on every Latitude cell swap regardless of cell quality. Run one full discharge to hibernate-cutoff under a live workload, then charge uninterrupted to 100%. The BIOS learn cycle rewrites its reference data and the warning clears after that cycle.

My E6220 shows 73Wh in system info but Windows reports a different design capacity — which is right?

The 73.26Wh figure in Dell's system information comes from the EEPROM value written into the battery pack, which reflects the rated chemistry spec. Windows pulls its design capacity figure from a separate ACPI data path and may display it in mWh rather than Wh, or round differently — 73,260mWh and 73.26Wh are the same value. If the figure shown is significantly lower, for example under 60,000mWh, run the BIOS battery learn cycle first, as the BIOS may be reporting a degraded-cell value carried over from the old pack's EEPROM.

New battery charged to 80% and stopped — Dell laptop won't charge past that point

The Latitude BIOS includes a firmware-controlled charge limit that caps charging at 80% when "primarily AC" mode is active in Dell Power Manager or the BIOS power settings. This is a BIOS setting, not a battery fault. Open Dell Power Manager, go to Battery Settings, and switch the charge mode from "Primarily AC" to "Adaptive" or "Standard." The battery will then charge to 100% on the next charge cycle.
