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 11 X360 — 7.6V Li-ion Replacement Battery (HSTNN-LB6B)
This is a 7.6V 3800mAh (28.88Wh) Li-ion replacement battery for the HP Pavilion 11 X360 convertible laptop. It fits the 11-N000 series, TPN-C115, and 11-N022NW, among the 200+ model variants that share the PL02XL cell platform. OEM part numbers covered include HSTNN-LB6B, PL02XL, 751875-001, and TPN-C115.
- X360 11-N series platform fit: Every model in this cluster runs the same 7.6V two-cell configuration with a shared BMS handshake protocol. HP kept the connector and EEPROM communication spec consistent across the 11-N000 production run, so one cell fits all variants without modification.
- Bench tested on actual hardware: We cycled this cell through charge, load, and hibernate-cutoff on the X360 platform. The BMS negotiated correctly, charge termination triggered at full capacity, and the protection circuit held steady under combined CPU and display load without tripping.
- First-cycle conditioning on the X360: After installing, run one full discharge until the laptop hibernates on its own, then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears after every cell swap on this platform.
BIOS reporting poor battery health after replacing the X360 cell
HP's BIOS reads health data from EEPROM stored on the original battery controller, not from live cell voltage. When a new cell goes in, the BIOS still holds the old EEPROM degradation record and flags the replacement as worn. This is not a fault with the new battery. Running one complete discharge-to-hibernate followed by a full uninterrupted charge forces the BIOS to overwrite that cached data and recalculate health against the new cell's actual capacity.
X360 shutting down at 20–30% charge shown on screen
This happens when the fuel gauge IC has not yet calibrated against the new cell's discharge curve. The displayed percentage is based on a voltage-to-capacity map built from the old cell — the new cell hits a voltage cliff at a different point. The laptop cuts power before the gauge catches up. Two to three full discharge-and-charge cycles recalibrate the fuel gauge IC. After calibration, shutdown should occur below 5% reported charge.

Frequently Asked Questions
My HP Pavilion 11 X360 shows the new battery as "0% available (plugged in, not charging)" — what's wrong?
This usually means the BIOS did not complete a handshake with the new cell's controller on first boot. Shut the laptop down fully, remove the battery, hold the power button for 15 seconds to drain residual charge from the board, then reseat the battery and power on. If it persists, run one full discharge cycle — the BIOS battery learn routine needs a complete cycle to register the new cell as valid.
Windows is showing 28Wh for this battery but HP Support Assistant lists a different Wh rating — is the cell wrong?
No. The Wh figure in HP Support Assistant is pulled from EEPROM data on the battery controller, which stores the OEM-rated value at manufacture. The 28.88Wh on this cell is the actual measured capacity at 7.6V and 3800mAh. The two numbers come from different sources and a small mismatch is normal. Check the voltage reading in HP Support Assistant — it should show 7.6V, which confirms the correct cell is installed.
The fuel gauge on my Pavilion 11 X360 is jumping around — showing 60%, then 80%, then dropping to 40% within minutes of unplugging
The fuel gauge IC is calibrating against the new cell's discharge curve and has not yet built an accurate voltage-to-capacity map. This typically settles after two to three complete discharge-and-charge cycles. For each calibration cycle, let the laptop discharge until it hibernates on its own, then charge to 100% without interruption. After the third cycle, the gauge reading should stabilise to within a few percent of actual remaining capacity.
