How to change garage door opener battery?


Changing the battery in a garage door opener is a simple task that can be done by anyone with basic DIY skills. This article will guide you through the process of changing a garage door opener battery, ensuring that your garage door continues to function smoothly and efficiently.

Step 1: Identify the Type of Battery

The first step in changing a garage door opener battery is to identify the type of battery used in your specific opener. Most garage door openers use either a 9-volt or a 12-volt battery. To determine the type of battery, you can refer to the user manual that came with your opener or check the battery compartment itself.

Step 2: Gather the Required Materials

Before you start the battery replacement process, gather the necessary materials. These typically include a new battery of the correct type, a screwdriver (usually a Phillips-head), and possibly a ladder or step stool to reach the opener.

Step 3: Disconnect the Power

To ensure your safety during the battery replacement process, it is important to disconnect the power to the garage door opener. Locate the power cord or the power switch on the opener and unplug it or switch it off.

Step 4: Access the Battery Compartment

Next, you will need to access the battery compartment. Depending on the model of your garage door opener, the battery compartment may be located on the back or side of the opener. Use the screwdriver to remove the screws holding the battery compartment cover in place.

Step 5: Remove the Old Battery

Once the battery compartment cover is removed, you can easily locate the old battery. Carefully remove the old battery from its compartment, taking note of its orientation. Some batteries may be connected with wires, so be cautious when disconnecting them.

Step 6: Insert the New Battery

Now it’s time to insert the new battery. Ensure that you insert the new battery in the correct orientation, following the markings or instructions on the battery or in the user manual. If the battery is connected with wires, reattach them securely.

Step 7: Replace the Battery Compartment Cover

After inserting the new battery, replace the battery compartment cover and secure it with the screws. Make sure the cover is tightly secured to prevent any damage or interference with the opener’s operation.

Step 8: Reconnect the Power

With the new battery in place and the battery compartment cover secured, you can now reconnect the power to the garage door opener. Plug the power cord back in or switch the power switch back on.

Step 9: Test the Garage Door Opener

To ensure that the battery replacement was successful, test the garage door opener. Press the remote control or wall button to open and close the garage door. If the door operates smoothly and without any issues, the battery replacement was successful.


Changing the battery in a garage door opener is a straightforward process that can be done by following a few simple steps. By identifying the type of battery, gathering the necessary materials, disconnecting the power, accessing the battery compartment, removing the old battery, inserting the new battery, replacing the battery compartment cover, reconnecting the power, and testing the opener, you can ensure that your garage door continues to function properly.
