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.

HP ENVY 14-3001TU Series — 14.8V Li-Polymer Replacement Battery (SL04XL)

This is a 14.8V, 3900mAh (57.72Wh) Li-Polymer replacement battery for the HP ENVY 14 Spectre ultrabook line. It fits the ENVY 14-3001TU, 14-3002TU, 14-3003TU, 14-3004TU, and over 40 additional ENVY 14 variants sharing the SL04XL platform. The OEM part numbers covered include SL04XL, 665054-171, TPN-Q105, and HSTNN-IB3J.

  • ENVY 14 Spectre platform fit: These models share a four-cell Li-Polymer pack at 14.8V nominal with a common BMS handshake and identical 290.14 × 114.25 × 7.08mm footprint. Any variant in the ENVY 14-3000 lineup that originally shipped with SL04XL pulls from the same voltage rail and connector spec.
  • Bench tested on actual hardware: We cycled this cell on an ENVY 14 Spectre chassis and confirmed BMS communication with the BIOS — the charge controller accepted the new cell, reported pack voltage correctly, and held a steady taper charge to 4.2V per cell without cutoff errors.
  • First-cycle recalibration on ENVY 14: After installing, discharge the laptop fully to hibernate cutoff under normal load — don't force it. Then charge uninterrupted to 100% without using the machine. This single cycle resets the BIOS battery learn cycle and clears the false "poor health" or "replace battery" warning that almost always appears after a cell swap on this platform.

BIOS reporting poor battery health immediately after fitting the SL04XL

The ENVY 14 BIOS reads health data from EEPROM registers stored in the old battery pack — not from the new cell's actual charge state. When a new cell is installed, those registers are blank or mismatched, so the BIOS flags the battery as degraded before it has run a single cycle. This is not a fault with the replacement cell. Running one full discharge-to-hibernate followed by an uninterrupted charge to 100% forces the fuel gauge IC to write fresh calibration data. After that cycle, BIOS health reporting normalises.

Laptop shuts off at 20–30% remaining shown on screen

This happens when the fuel gauge IC has not yet calibrated against the new cell's actual voltage curve. The displayed percentage is based on stale data — the cell hits a voltage cliff under combined CPU and display load before the gauge catches up. It is not a defective battery. Run two full discharge-to-hibernate cycles followed by full uninterrupted charges, and the gauge IC will map the correct cut-off point. After calibration, the laptop should sustain load down to approximately 11.1V pack voltage before shutdown.

Frequently Asked Questions

My HP ENVY 14 now shows the wrong Wh rating in system info after fitting the SL04XL — is that a firmware problem?

The Wh figure in Windows Battery Report and HP Support Assistant pulls from EEPROM data embedded in the pack, and the rated value in that register can differ slightly from the actual cell chemistry used in a replacement. This is a data mismatch, not a fault — the cell is still delivering its full 57.72Wh capacity. No firmware update is needed. Check actual full-charge capacity against design capacity after two calibration cycles using `powercfg /batteryreport` in Command Prompt.

The new battery charges up fine but the fuel gauge jumps around wildly — 67%, then 45%, then back to 71% within minutes.

The fuel gauge IC on the ENVY 14 mainboard needs several full cycles to build an accurate model of the new cell's discharge curve. Until it has that data, it interpolates from old parameters and the percentage reading swings. This settles after two to three full discharge-to-hibernate and uninterrupted full-charge cycles. Do not partially charge during calibration — each interrupted cycle delays the process. By cycle three, readings should track smoothly from 100% down.

Charge stops at 80% and the indicator light goes solid — is the SL04XL cell faulty or is this the BIOS limiting charge?

HP ENVY 14 BIOS on some firmware revisions includes an adaptive battery charge mode that caps charging at 80% to reduce cell stress during extended AC use. This is a BIOS-controlled limit — not a fault with the replacement cell. Open HP Support Assistant, go to Battery settings, and disable "Adaptive Battery Charging" or "Battery Care Function" if enabled. After disabling and unplugging then reconnecting AC, charging should continue past 80% and reach the 4.2V-per-cell full-charge threshold.
