    Why Do You Need To Replace Your Opener Battery?

    Garage door openers need a power source to function.

    The opener relies on electrical power since it is plugged into an electrical socket most of the time.

    But when a power failure occurs, your opener switches to battery power.

    This is why you must fully charge the backup battery of your opener.

    You should also ensure that the battery is in excellent condition.

    This way, you’ll be better prepared during emergencies.

    You also won’t need to give up the automatic operation of your garage door and enjoy convenience.

    Furthermore, a battery backup can give you peace of mind.

    It gives you the assurance that you can get in and out of your garage during an evacuation and power outage.

    Make sure the cables don’t come out of the compartment.

    1. Close the battery cover and secure it with a screw.

    Close the light lens afterward.

    1. Plug the garage door opener into a socket.

    You should see the LED light blinking green.

    This indicates that the backup battery is charging.

    When To Replace Liftmaster 8550 Battery

    Your garage door opener will usually give you a signal when it’s time to replace the battery.

    The Liftmaster 8550 battery can be found inside the garage door opener.

    It can last for one to two years with proper use and maintenance.

    You should know when your battery is near the end of its lifespan so that you can replace it on time.

    If not, you don’t have to worry because the opener will warn you.

    There’s an LED indicator for the status of the battery.

    If the LED indicator is a solid orange, it means the battery is running low, and you need to charge it.

    The Orange LED indicator is often accompanied by beeps every 2 seconds.
