Battery Care Tips
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
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 Pavilion 10 TouchSmart — 10.8V Li-ion Replacement Battery (MR03)
This is a 10.8V, 2400mAh (25.92Wh) Li-ion replacement battery for the HP Pavilion 10 TouchSmart notebook series. It fits the Pavilion 10 TouchSmart lineup including the 10-e010nr, 10-e019nr, and 10-e020ca, among others. OEM part numbers MR03 and HSTNN-IB5T both cross to this cell.
- Pavilion 10 TouchSmart compatibility: Every model in this series runs the same 10.8V three-cell architecture with the MR03 connector and BMS handshake. The voltage rail and charge protocol are identical across the 10-e0xx range, so one cell covers the full lineup.
- Bench tested on actual hardware: We ran this cell through charge-to-cutoff cycles on a Pavilion 10 TouchSmart unit. The BMS accepted the cell without fault codes, charge current ramped normally through CC/CV phases, and the fuel gauge IC updated correctly after two full cycles.
- Post-install calibration for the Pavilion 10: After fitting this cell, run one full discharge to hibernate-cutoff, then charge uninterrupted to 100%. The Pavilion 10's BIOS runs a battery learn cycle on the first full charge-discharge pass — skipping this step leaves the health indicator showing a false warning that persists across reboots.
BIOS reporting poor battery health immediately after fitting the new cell
HP's BIOS reads EEPROM data stored by the outgoing cell and compares it against the new cell's reported state. A fresh cell with no charge history looks inconsistent to the firmware, triggering a "battery not detected" or "poor health" flag. This is not a fault with the replacement cell — it is the BIOS misreading a clean slate. Run the Pavilion 10's battery learn cycle: discharge fully to hibernate, then charge to 100% without interruption. The BIOS clears the flag after one complete cycle.
Laptop shuts down abruptly when the charge indicator still shows 20–25%
This happens when the fuel gauge IC has not yet calibrated against the new cell's actual voltage curve. The IC carries over calibration data from the old, degraded cell and underestimates the voltage cliff. When combined CPU and display load pulls current hard, voltage drops faster than the gauge predicts, and the protection circuit trips before the displayed percentage reaches zero. Two full discharge-to-hibernate and charge-to-100% cycles reset the calibration. After the second cycle, the gauge tracks the new cell accurately and shutdowns stop.

Frequently Asked Questions
HP says the battery health is "poor" right after I put in the new one — did I get a bad cell?
The cell is almost certainly fine. HP's BIOS pulls EEPROM data from the old battery and flags a mismatch when a fresh cell with no charge history connects. Run one full discharge to hibernate-cutoff, then charge uninterrupted to 100% — the BIOS battery learn cycle rewrites that health data against the new cell and clears the warning after one complete pass.
My Pavilion 10 shuts off at around 20% and it's been doing it since I swapped the battery — what's causing it?
The fuel gauge IC carried over calibration data from your old, worn cell. That old data maps the wrong voltage curve onto the new cell, so the percentage reading is too high when the cell actually hits its low-voltage cutoff. Run two full discharge-to-hibernate cycles followed by uninterrupted charges to 100% — after the second cycle, the IC recalibrates and the premature shutdowns stop.
Windows is showing the wrong Wh rating for this battery — it says something different from the 25.92Wh on the listing. Is the cell mislabelled?
The Wh value Windows displays comes from EEPROM data embedded in the battery's BMS chip, which reflects the rated chemistry spec rather than a live measurement. Small differences between the listed 25.92Wh and what the OS reports are normal when the fuel gauge IC has not yet completed a calibration cycle. Do one full discharge to hibernate and a full charge to 100% — the reported value typically aligns with the rated spec once the IC has a complete cycle to reference.
