Before replacing the battery, it is crucial to power down your security system to avoid any issues. You can do this by unplugging the transformer from the wall outlet. This ensures all components are in a safe state during the battery replacement process.

Open the Panel

Locate the main panel, which is usually mounted on a wall. Remove the cover by either unscrewing it or releasing any clips. Ensure you handle the panel carefully to avoid damaging sensitive components.

Disconnect the Old Battery

Identify the battery inside the panel. Carefully disconnect the wires from the old battery, noting the orientation of the connections (positive and negative) for correct installation of the new battery.

Remove the Old Battery

Take out the old battery from its compartment. Be gentle to avoid any damage to the internal components or circuitry.

Install the New Battery

Place the new battery in the compartment, making sure it fits securely. Connect the wires to the new battery, ensuring the positive and negative terminals are correctly matched as noted earlier.

Replace the Panel Cover

Once the new battery is installed and connected, replace the panel cover and secure it with screws or clips. Ensure everything is properly sealed to prevent any dust or debris from entering the panel.

Reconnect Power

Plug the transformer back into the wall outlet to power the system. This step is crucial to ensure the new battery is charged and the system is operational.

Test the System

After replacing the battery, test your security system to ensure it is functioning properly. This includes checking sensors and alarms to ensure they are responding correctly to any potential threats.

Important Notes

Always use the correct type of replacement battery recommended by ADT to prevent any system failures. If you are unsure or uncomfortable performing the replacement, consider contacting ADT customer support or a professional technician for assistance. Be aware that some panels can trigger alarms or malfunction if you try to replace the battery yourself. A professional can help you safely perform the task and ensure the system remains under warranty.

By following these steps, you can ensure the battery in your ADT main panel is replaced correctly, maintaining the reliability and functionality of your security system.
