What Kind of Battery Does Your Garage Door Opener Need? (And Where to Get It)
If your garage door remote suddenly stops working, you’re probably wondering: Do I need a new battery for my garage door opener? You’re not alone. At Batteries Inc., one of the most common questions we get—right after “Is it broken?”—is how to know which battery is needed for a garage door remote or keypad. It’s an everyday problem with a surprisingly simple fix, and this guide is here to walk you through it.
Whether you’re a homeowner who’s just trying to get in and out of the garage without drama, or a contractor trying to keep clients happy, the right battery can save time, stress, and even prevent emergency repair calls. We’ve also partnered with some of the top garage door companies in the country—from Florida to Kentucky—to make sure you’re getting trusted, local help along the way.
Common Batteries Found in Garage Door Openers

Most garage door openers rely on just a few battery types, but the differences matter. Some remotes use 2032 coin cell batteries, while others require A23 12-volt batteries—a small but powerful option that’s easy to miss on store shelves. Other models use standard AA or AAA batteries, and certain wall-mounted units or backup systems run on 9V or rechargeable battery packs. Each type plays a different role depending on your system’s design and age.
Our good friends at Blue Steel Garage Doors down in Florida often tell us about the number of homeowners they help who are caught off guard by the kind of battery they need. The salty air and climate in coastal Florida can wear on battery contacts, so even the right battery needs to be replaced regularly. Their technicians are trained to carry all the most common types during service calls—something we’re proud to supply them with.
How to Tell What Battery Your Garage Door Remote Uses

If you’re not sure what battery your remote uses, don’t worry—it’s easier to figure out than it sounds. The fastest way is to check your opener’s user manual, but if that’s long gone, just pop open the back of the remote. Inside, you’ll usually see the battery type printed clearly, such as “CR2032” or “A23.” If not, snap a photo and bring it to us at Batteries Inc. We’ll match it on the spot.
In Kentucky, Hagan’s Garage Door Service often walks customers through this exact process over the phone. Their focus on customer care makes them a favorite in the Bluegrass State, and we love hearing how they go the extra mile to help folks who might be unfamiliar with garage tech. The team at Hagan’s always says, “There’s no such thing as a dumb battery question”—and we couldn’t agree more.
Why the Right Battery Matters for Performance

It may seem like any battery will do, but using the wrong type—or even a low-quality version of the right one—can affect your garage door opener’s performance. A weak battery often reduces the range of your remote, causes lag or dropped signals, and in some cases, fails altogether. During storms or emergencies, the last thing you want is a garage door that won’t open.
We’ve partnered with Access Garage Doors of Greenville, SC, who are experts at explaining the importance of preventive maintenance, including something as seemingly small as battery replacement. Their technicians frequently advise homeowners to change their garage door opener batteries before issues even arise, especially as the seasons change and temperatures affect performance.
Signs It’s Time to Replace the Battery

So how do you know when it’s time to swap in a new battery? A few telltale signs: the remote only works when you’re standing right next to the door, the button feels unresponsive, or the wall unit flashes or beeps repeatedly. These are your system’s way of saying, “Help me out!”
In colder climates like Utah, our longtime friends at Uplifting Garage Doors recommend swapping batteries every 12 months, even if things seem fine. The team says customers often get caught off guard during winter, when freezing temps expose battery weaknesses. They’ve even started including fresh batteries in their seasonal service packages—another reason we love working with them.
Backup Batteries: More Than Just Remotes
Most people don’t realize that garage doors may also rely on backup batteries, especially if you have a newer model designed to keep operating during power outages. These built-in battery packs often need replacing every 3–5 years and can be critical for keeping your garage functional in an emergency.
Batteries Inc. keeps a full inventory of rechargeable garage door batteries, both OEM and compatible options. We always recommend testing your backup system during daylight savings or before hurricane season. If you’re working with one of our garage door service partners, ask them if your system includes a backup—they’ll know exactly what to look for.
Where to Get the Right Battery (And Help Installing It)
We get it—shopping for batteries can feel confusing. That’s why we’ve made it simple. At Batteries Inc., you can walk in with a remote and walk out with exactly what you need. Not only do we carry every standard battery for garage door openers, but we’ll also install it for you while you wait—free of charge.
Better yet, if you’re working with pros like Hagan’s, Access, Uplifting, or Blue Steel, chances are they’re already using our batteries. We proudly support their technicians with fast shipping, in-stock inventory, and expert advice whenever they need it.
One Small Change, Big Convenience
Garage doors are one of those conveniences we rely on every day—until the moment they stop working. But often, it’s not a mechanical issue or an expensive repair. It’s just a battery. Knowing what to look for, and where to go for help, can save you from major headaches.
Whether you’re in South Carolina or across the country, Batteries Inc. is here to power your peace of mind. Stop by, give us a call, or ask your trusted garage door technician to recommend the right fit—we’ll take care of the rest.
