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 Inspiron 1410 / Vostro 1014 1015 A840 — 11.1V Li-ion Replacement Battery (312-0818)

This is an 11.1V 4400mAh Li-ion battery for the Dell Inspiron 1410, Vostro 1014, Vostro 1015, and Vostro A840 laptops. It slots into the same bay as the original and connects to the same three-pin power rail. Capacity is 4400mAh (48.84Wh), matching the standard-series spec for these models.

  • Inspiron 1410 and Vostro 1014/1015/A840 platform fit: These four models share the same battery bay dimensions, 11.1V rail, and BIOS handshake protocol. Dell used the same cell format and BMS communication spec across this chassis generation, so one part number covers all of them.
  • Bench tested on actual hardware: We ran this cell on an Inspiron 1410 and confirmed the BMS reported charge status correctly, the BIOS accepted the battery without fault codes, and the cell cycled through charge and discharge without thermal cutoff or unexpected voltage drop.
  • First-cycle calibration on Dell's fuel gauge IC: After installing, 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 on the first boot with a new cell.

Laptop shutting down at 20–30% remaining after battery swap

The old cell's discharge curve is stored in the fuel gauge IC. When a new cell goes in, the IC maps voltage readings against the old curve, which causes it to underestimate remaining capacity. Under full CPU and display load, voltage drops faster than the IC expects, and the system cuts out before the real charge is gone. Run two full discharge-to-hibernate and full-recharge cycles to let the IC recalibrate against the new cell's actual voltage curve. After calibration, the cutoff should track correctly down to the 10–11V low-voltage threshold.

BIOS reporting battery health as "poor" immediately after install

The BIOS reads health data from the battery's EEPROM, which on a new cell contains factory-default values that don't match a used system's charge history. Dell's battery health algorithm flags this mismatch as degraded capacity rather than a new cell. This is not a fault with the battery. Run the full discharge-to-hibernate then uninterrupted charge cycle once — the BIOS learn cycle will write a fresh baseline to the EEPROM and the warning will clear on the next boot.

Frequently Asked Questions

My Dell Vostro 1015 shows the new battery Wh rating as different from what the label says — is the cell wrong?

The Wh figure shown in system info is pulled from the EEPROM on the battery's BMS, not measured live. Factory EEPROM values are sometimes written to a rated chemistry spec that differs slightly from the actual tested capacity of the shipped cell. The 48.84Wh stamped on the label reflects the actual cell spec for this part. If the BIOS figure concerns you, run one full discharge-to-hibernate cycle and one full charge — some Dell BIOS versions update the displayed Wh after the first completed learn cycle.

The fuel gauge on my Inspiron 1410 is jumping around — showing 60%, then 45%, then 70% within minutes of each other.

The fuel gauge IC lost its reference curve when the old cell was removed. It's now estimating state-of-charge against a blank or mismatched baseline, so readings are unstable. This is normal for the first one to three cycles on a new cell. Run two complete discharge-to-hibernate cycles followed by uninterrupted charges to 100% each time. After two calibration cycles, the IC builds a stable voltage-to-capacity map and the gauge settles to within a few percent of actual charge.

New battery installed on Vostro A840 but charge stops at 80% and won't go higher — adapter light stays solid green.

Dell's BIOS on several Vostro and Inspiron models includes a charge-limit feature that caps charging at 80% when it's enabled. This is a firmware setting, not a fault with the cell. Go to the Dell Power Manager utility or BIOS power settings and check whether "Primary AC Use" or a charge threshold is turned on. Disable it, then reconnect the adapter — the battery will charge past 80% to 100%.
