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.

Dell Chromebook 13 7310 — 11.4V Li-Polymer Replacement Battery (092YR1)

This is an 11.4V, 5700mAh (64.98Wh) lithium-polymer battery for the Dell Chromebook 13 7310. It replaces OEM part numbers 092YR1, 0MJFM6, 0X3PH0, MJFM6, X3PH0, and X3PHO. Fit the correct part number before ordering — the 7310 is the only Chromebook 13 variant this cell matches.

  • Chromebook 13 7310 fitment: The 7310 uses a specific three-cell Li-Polymer pack with a dedicated BMS handshake tied to Dell's EC firmware. This cell matches the connector pinout, voltage rails, and pack dimensions (301.90 × 128.80 × 7.56mm) the 7310 expects on boot.
  • Bench tested on actual hardware: We cycled this cell through charge, discharge, and idle states on a 7310 unit. The BMS negotiated correctly with Dell's EC on first connection — no charge inhibit, no unknown battery flag on initial power-on.
  • Post-install calibration on the 7310: After fitting, 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 model.

BIOS reporting battery health as poor immediately after replacement

The 7310's BIOS reads health data from EEPROM embedded in the battery pack — not from live cell measurements. When a new cell arrives, the EEPROM holds factory baseline data that doesn't match the BIOS's stored history for the old pack. Dell's firmware flags this mismatch as "poor health" or "consider replacing." Running the battery learn cycle — full discharge to hibernate, then uninterrupted full charge — writes new baseline data and clears the flag.

Chromebook 13 7310 shutting down at 20–30% charge shown on screen

This is a voltage cliff symptom, not a calibration error. Under combined CPU and display load, the cell voltage drops faster than the fuel gauge IC predicts — the system hits the low-voltage cutoff while the OS still shows charge remaining. The fuel gauge IC needs two or three full calibration cycles against the new cell before its predictions track actual voltage accurately. Run full discharges to hibernate cutoff until the shutdown point drops below 10%.

Frequently Asked Questions

Dell Chromebook 13 7310 shows "0% available (plugged in, charging)" after I swapped the battery — what's wrong?

The fuel gauge IC on the 7310 loses its calibration reference when the cell is swapped. It reads 0% because its stored charge curve doesn't match the new cell's actual voltage profile. This isn't a faulty battery — it's an IC that needs to relearn. Run one full discharge to hibernate cutoff, plug in, and charge uninterrupted to 100% to reset the calibration baseline.

Why does the Chromebook 13 7310 show a different Wh rating in system info than what's on the battery label?

The Wh figure in Dell's system info pulls from EEPROM data written at the factory for the original pack. The replacement cell's EEPROM may carry a slightly different rated value due to chemistry tolerance differences between production batches. The physical capacity — 64.98Wh — is what the cell delivers under load. The EEPROM-reported figure in system info is a label, not a live measurement, and won't affect charge behaviour.

New battery installed in my Dell Chromebook 13 7310 but charging stops at 80% and won't go higher — is the cell defective?

Charge stopping at 80% is a BIOS-controlled charge limit, not a cell fault. Dell's firmware on the 7310 includes a battery care mode that caps charging at 80% to reduce long-term cell stress. Check the Dell Power Manager settings in ChromeOS — if "primarily AC" or a charge limit mode is active, disable it and the battery will charge to 100%.
