how to install BTI DR02XL-BTI 7.7V 43.7WHR Li-Ion Battery

Before you begin, ensure you power off the Chromebook completely and unplug any connected accessories or chargers. Work on a clean, static-free surface and handle the battery and device with care to protect delicate connectors.

Step 1: Remove the back cover to access the battery compartment. Use the appropriate screwdriver to carefully loosen screws and lift the back panel, taking note of how cables are routed inside the chassis.

Step 2: Disconnect the battery connector from the motherboard. Gently wiggle the connector free, avoiding excessive force that could damage the socket or cable. If your model uses adhesive strips, locate and release them without tearing.

Step 3: Remove the old battery. If the battery is secured with brackets or screws, remove them and lift the battery straight out of the compartment. Be mindful of any surrounding components that may be connected to the battery pack.

Step 4: Prepare the new battery for installation. Align the battery contacts with the motherboard socket and verify that the connector orientation matches the original part. Check the fit to ensure there is no interference with the chassis or other components.

Step 5: Connect the new battery. Reattach the battery connector firmly to the motherboard, ensuring a secure and stable connection. Check that the battery sits flat and does not press against internal parts or cables.

Step 6: Replace the back cover. Reinstall screws in a cross pattern to secure the panel evenly. Reconnect any cables or adhesive strips you previously detached, and confirm that the device sits properly when closed.

Step 7: Initial charging and testing. After reassembly, plug in the charger and allow the new battery to calibrate by charging to full, then using until it reaches a natural discharge. Observe the device for normal startup behavior, consistent battery indicator readings, and stable performance. If the battery does not initialize, double-check the connections and reseat the connector as needed.

Safety notes: Do not bend or crush the battery, avoid exposing it to excessive heat or moisture, and never attempt to puncture or disassemble the pack. If you notice swelling, abnormal heat, or unusual performance, discontinue use and seek professional service.
