In our 15 years serving Glendale, we've seen this problem again and again: the power goes out, and suddenly homeowners can't get their cars out of the garage. A battery backup system solves that. Whether you need one depends on your situation, your opener type, and how often outages hit your neighborhood. We'll walk you through the decision.
A battery backup unit keeps your garage door opener running when the grid goes down. Most modern systems sit inside or near your opener motor. When power fails, the battery kicks in and gives you enough juice to open or close the door maybe five to ten times. That's usually enough to get one or both cars out during an emergency.
Not every opener comes with battery backup built in. Older chain drive and belt drive models almost never do. Newer smart openers, especially those with MyQ technology, sometimes offer it as an add-on. The cost ranges from about $150 to $400 for the unit itself, plus installation labor.
Chain drive openers are heavy-duty workhorses, but they draw a lot of current. That makes battery backup less practical. Belt drive openers are quieter and lighter, which means a battery can power them more effectively. Screw drive openers fall somewhere in the middle.
If you're already thinking about replacing your opener, this is the time to ask whether a smart opener with battery backup makes sense. We've written a full guide on garage door openers in Glendale covering safety, cost, and which type to choose. That post breaks down the pros and cons of each system so you can decide what fits your home and budget.
Glendale doesn't experience frequent power outages like some inland California regions do. But if you live near transmission lines or in an area that lost power during the 2023 rolling blackouts, battery backup becomes more valuable. Same goes if you have a medical condition that requires you to leave quickly, or if you work from home and need garage access during the day.
Here's a practical question: can you manually open your door? Garage doors have a release mechanism that lets you pull the door up by hand during an outage. It takes strength and coordination, but it works. If that's not an option for you, battery backup is worth the investment.

A battery backup system isn't cheap, but neither is being stuck in your garage during an emergency. The cost typically breaks down this way: $150 to $300 for the unit, plus $100 to $200 in labor for installation. Some homeowners bundle it into a full opener replacement, which can reduce per-item labor costs.
If you're already budgeting for a new opener because your old one is failing, adding battery backup costs maybe 15 to 20 percent more. That's a better deal than retrofitting an old opener.

MyQ and similar smart garage door technologies have changed the game. These systems let you open and close your door from your phone, set schedules, and receive alerts. Many smart openers now offer battery backup as standard or as an affordable add-on. Some even send you notifications when the battery is running low.
The catch: smart openers cost more upfront. But if you're already paying for that technology, the battery backup is a logical addition. We've covered this in depth in our smart garage door technology guide for 2025. That post explains what features actually matter and which ones are nice-to-have.
Installation is straightforward for a qualified technician. Most battery units bolt onto or into the opener motor housing, and wiring takes under an hour. The real work is making sure the system works correctly before you need it.
Batteries lose capacity over time. A typical garage door opener battery lasts 3 to 5 years before it needs replacement. When you buy a battery backup unit, ask your installer about warranty coverage and replacement costs. Some batteries cost $50 to replace, others closer to $150.
Battery backup makes sense if you live in an area prone to outages, if you can't manually open your garage door, or if you're already investing in a new smart opener. It doesn't make sense if outages are rare, you're not replacing your opener soon, or your door has a working manual release that you can operate.
The best move is to talk through your specific situation with a technician. Call us at 424-379-4029 or get a same-day estimate online. We'll evaluate your current opener and tell you honestly whether battery backup is worth the money for your home.
Your garage door should work when you need it, power outage or not. That's what we're here for.
How long does a garage door battery backup last? A single charge typically opens and closes the door five to ten times. Most outages in Glendale last a few hours, so that's usually enough. Battery units themselves last three to five years before replacement.
Can I add battery backup to my existing opener? Maybe. Newer openers can accept battery backup modules. Older chain drive systems often can't because they draw too much current. A technician can evaluate your specific opener and let you know if it's possible.
What's the difference between battery backup and a backup power generator? Battery backup is built into your opener and works automatically. A generator powers your whole house but requires installation, fuel, and maintenance. Battery backup is simpler and cheaper for just garage door access.
Does MyQ work without power? No. The MyQ app and smart features require internet, which goes down when power does. Battery backup lets you open the door manually, but you won't get app notifications during the outage.
How much does battery backup cost to install in Glendale? Most systems cost $250 to $500 installed, depending on your opener type. Retrofitting an old opener costs more than adding it to a new one. Call 424-379-4029 for a free quote.
