How to install BTI 808450-001-BTI Battery

• Power down your HP ZBook Studio G3 or G4 completely and unplug from any power source. Ensure you’re working on a flat, static-free surface and that the device is cool to the touch.
• Close all applications and, if possible, remove any external peripherals to prevent accidental damage during replacement.
• Place the laptop face down and carefully remove the bottom panel using the appropriate screwdriver. Keep track of screws and note their locations for reassembly.
• Locate the battery connector and disconnect it from the motherboard. If you encounter resistance, consult your service manuals or the manufacturer’s guidance to avoid damaging the connector or wiring.
• Remove the old battery from its compartment, taking care not to damage surrounding components. Align the new BTI 808450-001-BTI battery with the mounting points and slide it securely into place.
• Reconnect the battery connector to the motherboard, reattach the bottom panel with the original screws, and power on the device. Allow the system to boot fully and begin the initial battery calibration cycle. If the system prompts a battery health check, follow the on-screen instructions to complete the calibration.
• Let the battery reach a full charge for the first few cycles to establish a baseline, then monitor runtime and charge cycles. For best results, avoid letting the battery discharge completely on a regular basis and keep the device in moderate temperatures during operation and charging.
