How to install BTI HP-EB850 11.1V 50Wh Li-Ion Battery

• Power off your HP EliteBook or ZBook and disconnect the charger. For best results, remove all peripherals and save your work before you begin.
• Place the laptop on a clean, flat surface and carefully remove the back cover or bottom panel according to your model’s service guide. Use the appropriate screwdriver for your device and keep screws organized for reassembly.
• Disconnect the existing battery connector from the notebook’s motherboard or battery bus. Gently lift the old battery away, taking care not to damage adjacent components or connectors.
• Align the BTI HP-EB850 in the same orientation as the original battery, connect the battery cable securely to the motherboard, and reseat any retaining brackets if present. Reinstall the back cover and secure all screws to manufacturer torque specifications.
• Power on the laptop and allow the battery to initialize. It’s recommended to perform a full cycle—charge to 100% and discharge to around 5-10% once or twice—to calibrate the battery gauge for accurate remaining-runtime reporting. If needed, run any battery-health utilities offered by your HP BIOS or operating system to finalize calibration.

Frequently asked questions

• Q: Is the BTI HP-EB850 compatible with my HP EliteBook or ZBook? A: The BTI HP-EB850 is designed as a compatible replacement for a wide range of HP EliteBook and ZBook models, including those listed in the compatibility notes. If your device uses one of the OEM part numbers listed (716724-421, CM03XL, 717375-001, E&U24ET, 717376-001, E7U24AA, CM03, E7U24UT), this battery should fit and function correctly.
