Keep reading for everything you need to know about installing a backup battery for your residential garage door opener!

What Is Battery Backup and How Does It Work?

A battery backup is an important feature found in modern garage door openers. This allows the opener to continue working even if the main power source is not available, as you will still have battery power. This can be incredibly beneficial if a severe storm cuts off electrical power to the neighborhood.

Instead of being stuck outside in the cold, you can use the backup battery to open your garage and get inside quickly. The system works by using a set of high-capacity batteries that are connected directly to the opener's motor and track rails. When these batteries run low, they activate an LED warning light, so it's easy to know when it's time for a replacement.

Whether you live in an area with frequent electrical outages or just want some extra assurance when opening your garage in an emergency, investing in a garage door opener with battery backup is sure to provide plenty of peace of mind.

Take time with these steps to double-check your work; it'll be worth it in the end!

Step 5: Mount All Wires, Cables, and Additional Parts Needed for Installation, Including a New Motor Controller Board in Place
