Fits Dell Inspiron 13R and 150+ compatible models replacing OEM part J1KND.
Supplies 11.1V at 4400mAh, restoring full portable runtime to machines that won't charge past 80% or show critically low fuel gauge readings after the original cell degrades.
Connector seats flush into the battery slot with a single locking tab — orientation is fixed, no force needed on insertion.
We bench tested the cell against a dead J1KND pull; BMS accepted the handshake on first charge and held voltage under sustained CPU and display load without cutoff.
After installation, discharge fully to hibernate shutdown then charge uninterrupted to 100% — this resets the BIOS battery learn cycle and clears the false poor-health warning that appears after every cell swap on this platform.

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 13R / 14R Series — 11.1V Li-ion Replacement Battery (J1KND)

This is an 11.1V, 4400mAh (48.84Wh) Li-ion battery for the Dell Inspiron 13R, 13R N3010, 13R N3010D, 14R, and related Inspiron notebook models. It replaces the original cell when capacity fade prevents the laptop from running on portable power. Cross-references include J1KND, 04YRJH, FMHC10, TKV2V, and several Dell P-series platform codes.

  • Inspiron 13R / 14R platform fit: These Inspiron models share a common 11.1V three-cell battery bay, connector pinout, and BMS handshake protocol across the N3010, N4010, N4110, and related chassis. One cell services the full range because the voltage rail and communication bus do not change between those sub-models.
  • Bench tested on actual hardware: We ran this cell on an Inspiron 14R N4010. The BMS handshake completed within one boot cycle, charge acceptance began immediately, and the fuel gauge IC tracked state-of-charge without error flags through a full charge and partial discharge cycle.
  • First-cycle calibration on Dell Inspiron: 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 commonly appears after any cell swap on these platforms.

BIOS reporting battery health as poor immediately after replacement

Dell's BIOS reads health data from EEPROM embedded in the battery pack, not from live cell voltage. When a new cell installs, that EEPROM data does not match the old pack's logged history, so the BIOS flags the battery as degraded or unknown. This is not a fault with the new cell. Run the full discharge-to-hibernate then uninterrupted charge cycle described above. After one or two complete cycles, the fuel gauge IC recalibrates and the BIOS health indicator updates to reflect actual cell condition.

Laptop shuts down abruptly at 20–30% charge shown on screen

This symptom points to a voltage cliff in the old cell, not the replacement. An aged Li-ion cell holds its reported state-of-charge until load spikes — such as full CPU plus display brightness — pull the terminal voltage below the BMS cutoff threshold in milliseconds. The OS fuel gauge has no time to update before shutdown occurs. Confirm the issue is resolved by running a full discharge cycle on the new cell and checking that terminal voltage stays above 10.8V under sustained load before the gauge reaches 20%.

Frequently Asked Questions

Dell BIOS says "consider replacing your battery" right after I installed this new one — is the cell actually bad?

The cell is not bad. Dell's BIOS reads a health score from the pack's EEPROM, and a freshly installed cell has no charge history logged yet, so the BIOS flags it as degraded by default. Run one full discharge to hibernate cutoff, then charge uninterrupted to 100% without interruption. After one or two complete cycles the fuel gauge IC recalibrates against the new cell and the warning clears.

My Inspiron's battery percentage jumps around wildly — it reads 60%, then 45% a minute later without any load change.

The fuel gauge IC on these Dell Inspiron boards needs two to three full charge and discharge cycles to map its internal model against the new cell's actual capacity curve. Until those calibration cycles complete, state-of-charge readings are interpolated from the old cell's data and will be inaccurate. Run two uninterrupted full cycles — discharge to hibernate, charge to 100% — and the gauge will stabilise. If it remains erratic after three cycles, check that the BIOS is not capping charge at 80% under a Dell Power Manager charge limit setting.

The system info panel shows this battery as 40Wh but the spec says 48.84Wh — why does the Wh rating look wrong?

Windows reads the Wh rating from the EEPROM data embedded in the pack, which stores the rated design capacity. On some Dell replacement cells the EEPROM value reflects a conservative factory floor figure rather than the full 48.84Wh chemistry capacity, creating a mismatch in system info. This does not affect actual charge delivery or runtime. Verify the cell is functioning correctly by checking that full-charge voltage reads between 12.4V and 12.6V at the battery terminals after a complete charge cycle.
