Which one should you choose?
- Want the longest runtime? Choose 46 Wh (L71607-005).
- On a tighter budget or stock is limited? The 41 Wh (L11119-855) is widely available and fully supported.
- Upgrading from 41 Wh? Swapping to 46 Wh is typically plug-and-play—no OS tweaks required.
Note: Both use the same connector style for this platform, and mounting points align across typical 240 G8 configurations.
How to confirm compatibility on your 240 G8
- Check your current battery label: Look for HT03XL / L11119-855 (3-cell) or UG04XL / L71607-005 (4-cell).
- Find your Product Number: On the bottom cover or in BIOS/HP Support Assistant (e.g., 2W9xxEA) and include it when ordering.
- Match the spare number first: Use L11119-855 or L71607-005 when speaking with a supplier.
Battery replacement overview
Tools: Phillips #0/#00, plastic opening pick/spudger, tweezers (optional), ESD strap (recommended)
- Shut down & prep: Power off, unplug AC, hold the power button for 15 seconds to discharge.
- Remove bottom cover: Unscrew all visible screws (some hide under feet). Pry clips gently starting from the hinge side with a plastic tool.
- Disconnect the battery: Slide the battery plug straight out of the board socket (don’t lever the socket).
- Swap the pack: Remove battery screws, lift old pack, place new one, align holes, reinstall screws snugly, reconnect the cable.
- Reassemble & test: Refit the cover, connect AC, boot, and confirm the battery is detected and charging.
Optional calibration: Charge to 100% → rest 30–60 min plugged in → use on battery down to 5–10% → recharge to 100% to help the fuel gauge learn the new pack.
Troubleshooting & tips
- Not detected or stuck at 0%: Reseat the connector, perform an embedded-controller reset (unplug AC, hold power 15 s), and update BIOS.
- Rapid drain just after replacement: Allow 1–3 full cycles; also check Windows updates and background apps.
- Label shows 41.04 vs 41.7 Wh (or 46.x Wh): Small capacity variations across cell vendors are normal.
- Recycle the old pack: Tape the connector and take it to an e-waste collection point—don’t trash lithium batteries.
