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 Notebook X2 10-P043TU — 7.7V Li-Polymer Replacement Battery (SW02XL)
This 7.7V, 4200mAh (32.34Wh) Li-Polymer cell replaces the original SW02XL battery in the HP Pavilion x2 10 series hybrid tablet-laptop. It fits the 10-P043TU along with the 10-P000NA, 10-P000ND, 10-P000NF, and 167+ additional x2 10 variants. The connector, BMS handshake, and physical form factor match OEM spec across the full P-series lineup.
- x2 10 P-series compatibility: Every model in this lineup runs the same 7.7V two-cell Li-Polymer configuration with a shared BMS communication protocol. HP standardised the SW02XL form factor across the P-series so one cell covers the full range — the HSTNN-IB7N and HSTNN-LB7N designations refer to the same physical pack with different regional part codes.
- Bench tested on actual hardware: We cycled this cell on a 10-P series unit and confirmed the BMS completed handshake without fault codes. Charge acceptance ran clean from 0% to 100% with no mid-cycle cutoff. The EEPROM read-back matched expected Wh values after two full calibration cycles.
- Post-install calibration — x2 10 hybrid: After fitting this cell, run the tablet side down to hibernate-cutoff under normal load — screen on, a few browser tabs open. Then charge uninterrupted to 100% without disconnecting. This forces the fuel gauge IC to re-baseline against the new cell and clears the inaccurate health warning the BIOS throws after every cell swap.
BIOS reporting poor battery health immediately after swap
The HP x2 10 BIOS stores learned battery data in EEPROM tied to the original cell. When a new cell goes in, that stored data no longer matches the actual chemistry, so the BIOS flags the pack as degraded or unknown — even on a brand-new replacement. This is a firmware calibration issue, not a cell fault. Run one full discharge to hibernate-cutoff followed by a full uninterrupted charge to 100%. After two cycles, the fuel gauge IC re-learns the cell's actual capacity curve and the health warning clears.
Tablet shutting down at 20–30% charge shown on screen
This happens when the fuel gauge IC has not yet calibrated to the new cell's voltage curve. The x2 10 runs a combined CPU-plus-display load during active use that pulls enough current to expose a steep voltage cliff in an uncalibrated cell — the BMS interprets that voltage drop as empty and triggers a shutdown even though capacity remains. The fix is the same calibration cycle: discharge fully to hibernate, charge straight to 100% without interruption, and repeat once more. After two cycles, the OS reading will track actual cell state down to around 3.0V per cell before cutoff.

Frequently Asked Questions
Why does Windows show the battery Wh rating as different from what I ordered — is it the wrong part?
The Wh figure Windows reports is pulled from EEPROM data written to the original cell at the factory. A replacement cell carries its own EEPROM values, which may differ slightly from what the old pack reported even when the chemistry and rated capacity are identical. This is a firmware read-back difference, not a capacity shortfall. Run two full discharge-to-hibernate, charge-to-100% cycles and the reported Wh will settle to the correct figure as the fuel gauge IC re-maps the new cell.
The x2 10 charges to 100% the first time but only reaches about 80% on every charge after that — what changed?
HP's BIOS on the x2 10 series includes a battery charge limit setting that can activate automatically after certain firmware updates or after a cell swap triggers a health-check routine. Open HP Support Assistant, navigate to Battery settings, and confirm the charge limit is set to full rather than the 80% extended-life mode. If the setting is already at full, reset it to 80%, save, reboot, then switch it back to full — this forces the BIOS to re-register the new cell's charge profile.
The fuel gauge jumps around wildly for the first few uses — shows 60%, then 90%, then drops to 15% within minutes. Is the cell faulty?
The fuel gauge IC on the x2 10 uses data from the previous cell to estimate charge state. With a new cell installed, those reference points are wrong, so the percentage reading swings until the IC collects enough real discharge data to recalibrate. We see this on the bench with every fresh cell swap on this platform — it is not a cell defect. Complete two full discharge-to-hibernate cycles followed by uninterrupted charges to 100% and the gauge will stabilise to within a few percent of actual charge state.
