Why Choose This WK06XL Battery
83Wh High-Capacity Pack
6-cell, 7160mAh, 83Wh delivers 4-8 hours of light productivity and up to 2 hours of gaming. One of the largest capacities for Omen laptops.
Genuine WK06XL — Not WK04XL
11.58V, 6-cell, 83Wh. Verify your label says WK06XL or HSTNN-OB21. WK04XL (15.4V, 4-cell) is a different battery and not interchangeable.
300-500 Charge Cycles
Rated for 300-500 full charge-discharge cycles. Use HP Adaptive Battery Optimizer to cap charging at 80% when plugged in — extends lifespan significantly.
Fits Omen 16 & 17 CK
Compatible with Omen 16-B, 16-C, and 17-CK series. One battery model covers multiple Omen lines. Match your label to confirm.
Brand New Genuine Cells
Not refurbished, not third-party. Genuine HP-specification Li-Ion cells deliver the full 83Wh capacity from day one.
1-Year Replacement Warranty
Covered by a full 1-year warranty. Premature capacity loss, charging failure, or any defect — replaced at no cost within 12 months.
Frequently Asked Questions
Q: How long does the WK06XL 83Wh battery last on a single charge?
A: Runtime varies dramatically by usage. Light tasks (web browsing, office work, video streaming with battery saver mode): 4-8 hours. Light gaming on battery saver: 2-6 hours. Heavy gaming with dedicated GPU at full power and high screen brightness: 1-2 hours maximum. Like all gaming laptops, the Omen's high-performance GPU drains battery quickly under load. For maximum runtime during non-gaming use, switch to integrated graphics, lower screen brightness, and enable battery saver mode.
Q: How do I install the WK06XL battery in my HP Omen?
A: Tools: Phillips #00/1 screwdriver, plastic pry tool. Steps: 1) Shut down, unplug, hold power button 15 seconds. 2) Remove 8 bottom panel screws (4 each side of vents). 3) Use pry tool from rear hinge area to release bottom cover clips — work around edges gently. 4) Locate the battery — gently wiggle the 12-pin connector left and right until it releases. Pull both ends simultaneously, never by the wires. 5) Remove 4-6 battery mounting screws. 6) Lift out old battery — do not bend or puncture. 7) Place new WK06XL, secure screws, connect cable, snap bottom cover on, replace 8 screws. Full process takes 20-45 minutes.
Q: How do I calibrate the new WK06XL battery after installation?
A: Manual method: 1) Charge to 100% and leave plugged in 1-2 more hours. 2) Use on battery until 5-10% (do not let it hit 0%). 3) Recharge to 100% uninterrupted. 4) Repeat this full cycle 3-4 times during the first week — this maximizes cell capacity and ensures accurate percentage readings. HP BIOS method: Restart, press F2 for HP PC Hardware Diagnostics UEFI → Component Tests → Battery → Calibrate. The automated process takes 4-8 hours but yields the most accurate calibration. Run `powercfg /batteryreport` afterward to verify full charge capacity matches design capacity (83Wh).
Q: WK06XL vs WK04XL — what is the difference and are they interchangeable?
A: No, they are NOT interchangeable. WK06XL (HSTNN-OB21) is 11.58V, 83Wh, 6-cell. WK04XL is 15.4V, 70Wh, 4-cell. Different voltage, different cell count, different physical dimensions. Using the wrong battery can cause charging failure, error messages, or even damage to the laptop's power circuitry. Always verify the code on your original battery label — it must say WK06XL or HSTNN-OB21. If your label shows WK04XL or any other code, this is not the correct battery.
Q: Which HP Omen models are NOT compatible with this WK06XL battery?
A: This battery fits Omen 16-B, 16-C, and 17-CK series only. It does NOT fit Omen models using WK04XL (different voltage), older Omen 15/17 models (pre-2021), Omen X series, Omen Transcend, Victus models requiring different battery codes, HP Pavilion Gaming, or any non-Omen HP laptop. Always verify the battery code on your original label — WK06XL or HSTNN-OB21 confirms compatibility.
Q: What HP part numbers does the WK06XL battery replace?
A: This battery replaces 4 HP part numbers: WK06XL (primary model code), HSTNN-OB21 (HP internal identification code), M41640-AC1 (spare part variant), and M41711-005 (primary HP spare part number). Any of these codes on your original battery label confirms this replacement fits.
Q: How can I extend my Omen battery lifespan?
A: 1: Enable HP Adaptive Battery Optimizer in the BIOS — this caps charging at ~80% when the laptop is mostly plugged in, significantly reducing cell wear. 2: Avoid deep discharges below 10% — recharge at 15-20%. 3: Do not leave the battery at 100% for weeks while plugged in. 4: Store at ~40% if not using for extended periods. 5: Exercise the battery — run on battery power at least once every 2-3 weeks. 6: Keep the laptop cool — heat is the #1 enemy of Li-Ion lifespan. Use a cooling pad during extended gaming sessions.
