How to install BTI 7WNW1-BTI 11.4V 51WH Li-ion Battery

• Shut down your Latitude laptop completely and unplug the power adapter. Ensure the device is off and not in sleep or hibernate mode before starting the replacement process.
• Turn the laptop over and locate the bottom cover screws. Use the appropriate screwdriver to remove the screws securing the back panel. Gently lift the cover to expose the internal components, taking care not to bend any cables.
• Disconnect the existing battery’s connector from the motherboard. Do this by carefully pulling the connector straight away from the socket, avoiding sideways tugs to prevent damage.
• Remove the old battery from its bay and set it aside. Align the new BTI 7WNW1-BTI battery with the compartment, ensuring the connector aligns with the motherboard port.
• Reconnect the new battery’s connector, secure the battery in place with any mounting brackets or screws if required, and reattach the bottom cover. Replace the screws firmly but not over-tightened.
• Power on the laptop and let it initialize. If the system prompts to calibrate the new battery, follow on-screen instructions or perform a full charge cycle (cycle from 0% to 100%) to help the battery’s gauge establish an accurate charge level.
• Once the battery is calibrated, use the charger to reach a full capacity, then dismount once you’re confident the power indicator reflects accurate remaining life. Properly dispose of or recycle the old battery in accordance with local regulations.
