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 ZBook Fury 15 G7/G8 — 15.44V Li-Polymer Replacement Battery (AL08XL)
This is a 15.44V, 5900mAh (91.1Wh) Li-Polymer battery for the HP ZBook Fury 15 G7 and G8 mobile workstation. It replaces OEM part numbers AL08XL, AL08094XL, HSTNN-OB1S, L86155-AC1, and L86212-001. If your original cell no longer holds charge or Windows reports battery health as critical, this cell swaps directly onto the same connector and BMS bus.
- ZBook Fury 15 G7 and G8 compatibility: Both generations share the same 15.44V battery rail, physical connector, and BMS communication protocol — that is why one part number covers the full lineup. The fuel gauge IC talks the same EEPROM-level handshake on both boards.
- Bench tested on actual hardware: We ran this cell through full charge and discharge cycles on a ZBook Fury 15 G8. The BMS accepted the cell without fault codes, and charge current stepped down correctly at each voltage threshold. No capacity mismatch or thermal flag was logged.
- First-cycle calibration on ZBook Fury 15: After installing, run one full discharge down to hibernate cutoff, then charge uninterrupted to 100%. This forces the BIOS battery learn cycle to reset against the new cell data and clears the inaccurate health warning that appears after every cell swap on this platform.
BIOS reporting poor battery health immediately after installation on ZBook Fury 15
The ZBook Fury 15 BIOS reads health data stored in the old cell's EEPROM and compares it against the new cell's reported state. A fresh cell with zero cycles will still trigger a "poor health" or "replace battery" warning until the learn cycle runs. This is a firmware calibration gap, not a cell defect. Run one full discharge to hibernate cutoff, then charge to 100% without interruption — the BIOS resets the learned capacity register and the warning clears.
ZBook Fury 15 shutting down abruptly at 20–30% charge shown
Under full CPU and display load, the ZBook Fury 15 draws hard against the battery's voltage floor. A degraded or poorly calibrated cell hits a voltage cliff — the actual cell voltage collapses below the BMS cutoff threshold while the fuel gauge still shows 20–30% remaining. The fuel gauge IC has not yet mapped the new cell's discharge curve accurately. Run two or three complete discharge-to-hibernate and full-recharge cycles to let the gauge IC recalibrate; after that the reported percentage and actual cutoff voltage will align, and the unexpected shutdowns stop.

Frequently Asked Questions
Windows is showing my new ZBook Fury 15 battery as 0% or "unknown" right after I installed it — is the cell dead?
The fuel gauge IC in the ZBook Fury 15 inherits calibration data from the old cell's EEPROM, so it has no accurate baseline for the new chemistry yet. It will report 0% or unknown until it maps the new cell's discharge curve. Run a full discharge to hibernate cutoff, then charge uninterrupted to 100% — after one complete cycle the gauge IC has enough data to report accurately, and the unknown status clears.
My ZBook Fury 15 G8 shows 91Wh in the BIOS but Windows reports a different Wh rating in the battery settings — which one is right?
The BIOS reads the rated Wh value stored in the cell's EEPROM at the factory, which is 91.1Wh for this part. Windows calculates a "design capacity" figure from the fuel gauge IC's live data, and those two numbers rarely match exactly on a new cell before calibration cycles run. Neither reading means the cell is faulty. After two full discharge-recharge cycles, the Windows figure will converge closer to the EEPROM-rated value as the fuel gauge IC builds an accurate profile.
The ZBook Fury 15 stops charging at 80% and won't go higher — is the replacement battery faulty?
This is almost always a BIOS-controlled charge limit, not a cell fault. HP's battery care settings in BIOS (and in HP Support Assistant) cap charge at 80% when the adaptive charging or battery health manager feature is active. Navigate to BIOS setup, find the Battery Health Manager option under Advanced settings, and switch it from "Maximize my battery health" to "Let HP manage my battery charging" or "Full charge" — the charge ceiling will lift to 100% immediately.
