When the power goes out, an opener without battery backup turns your garage door into a 150-pound wall. You either pull the emergency release and lift it by hand, or your car stays stuck inside. Battery backup keeps the door working through the outage, and in California it’s required by law.
We compared current models from Chamberlain, LiftMaster and Genie against their manufacturer pages, and removed models that have been discontinued. These are research-based picks, not lab tests.

Short Answer: The Chamberlain B4613T is the best garage door opener with battery backup for most homes: belt drive, myQ app control and a wireless keypad, with the backup battery included. Choose the LiftMaster 87504-267 if you want a built-in camera, the Genie StealthDrive Connect 7155-TKV for the most backup cycles and Alexa support, or the Genie ChainMax 1000 3022-BC on a tighter budget.
Why Battery Backup Matters
California’s Senate Bill 969 has required battery backup on residential garage door openers sold or installed in the state since July 2019, after wildfire power shutoffs left people unable to get their cars out. Outside California it’s optional, but the reasoning applies anywhere storms knock out power.
For many households the garage is the main way in and out. A backup battery means the door still opens with your remote or keypad during an outage, and it closes again so your home isn’t left open.

The Best Garage Door Openers With Battery Backup
Each pick below includes the backup battery in the box, so there’s nothing extra to buy.
Chamberlain B4613T: Best Overall
The B4613T covers what most homeowners need. It’s a quiet 3/4 HP-equivalent DC belt drive with myQ Wi-Fi for phone control and alerts, a wireless keypad in the box, an integrated LED light with motion detection, and a backup battery included.
It replaced the popular Chamberlain B970, which is discontinued, so it’s the model to buy if an older guide sent you looking for the B970. The trade-off: myQ doesn’t work with Alexa or Google Assistant natively.
LiftMaster 87504-267: Best With a Camera
LiftMaster’s Secure View 87504-267 adds a 1080p camera with night vision and two-way audio to a quiet DC belt drive, plus a 2,000-lumen LED lighting system. Its battery backup is included and meets California’s SB-969 requirement.
Live view and alerts are free in the myQ app, but recording video needs a paid myQ plan, starting at $49.99 a year. Like the Chamberlain, it doesn’t work with Alexa or Google natively.
Genie StealthDrive Connect 7155-TKV: Most Backup Cycles
Genie lists up to 50 cycles on battery backup for the 7155-TKV, the highest figure among our picks. Its 1-1/4 HPc DC belt drive is rated for sectional doors up to 500 pounds, so it’s also the pick for heavy wood or insulated double doors.
Genie’s Aladdin Connect app works with Alexa and Google Assistant directly. Two remotes, a wireless keypad and a wall console with a vacation lock are included. The standard rail fits a 7-foot door; an 8-foot door needs Genie’s extension kit.
Genie ChainMax 1000 3022-BC: Best Budget Pick
The ChainMax 1000 3022-BC is Genie’s heavy-duty chain drive with a 140V DC motor and battery backup. Chain drives are louder than belt drives, so this suits a detached garage or one that doesn’t sit under a bedroom.
Genie sells several ChainMax 1000 versions with different accessories and smart features, so check the listing for exactly what’s included before you order.
Need a wall-mount opener to keep the ceiling clear? LiftMaster’s 98022 jackshaft opener supports battery backup too. Our guide to the best opener for an 8-foot door covers wall-mount options.
How Long Does Battery Backup Last?
Backup is measured in cycles, where one cycle is one open and one close. LiftMaster and Chamberlain backup batteries are commonly rated around 20 cycles per charge, and Genie lists up to 50 for the 7155-TKV. At two trips a day, 20 cycles covers about a week-long outage if you’re careful.
The battery itself wears out. LiftMaster’s replacement backup battery, the 485LM, is a 12V sealed lead-acid pack that typically needs replacing every couple of years. Most openers beep or flash a light when it’s getting weak.
| Battery Task | How Often | Cost | DIY Suitability |
|---|---|---|---|
| Test backup (unplug opener, run the door) | Once a year | $0 | Safe for DIY |
| Replace backup battery | Every 2 to 3 years | $40 to $80 | Safe for DIY |
| Replace opener without backup | When it fails | Price of new unit | DIY with care |
Can You Add Battery Backup to an Existing Opener?
Sometimes. Many LiftMaster openers are built “battery-ready” and accept the 485LM battery as an add-on, including the 8550W, 8360, 8500W and 87504-267. If your LiftMaster has an empty battery compartment, check your manual for the 485LM.
If your opener wasn’t designed for one, you can’t bolt a battery on, and replacing the opener is the only way to get backup. That’s also the safest route in California, where new installs must include it.
What to Look for When You Buy
Check four things. First, that battery backup is included, not just “compatible”, which can mean it’s sold separately. Second, the cycle rating if the maker lists it. Third, drive type: belt drives are quieter for attached garages, chain drives are cheaper and fine for detached ones. Fourth, the app ecosystem, because myQ (LiftMaster and Chamberlain) has no native Alexa or Google support, while Genie’s Aladdin Connect has both.
In our experience helping homeowners pick openers, battery backup is the feature people most often wish they’d paid for after their first long outage. For more on app control, see our best WiFi garage door openers guide.
Frequently Asked Questions
How long does a garage door opener battery backup last?
Most are rated around 20 cycles per charge; Genie lists up to 50 for the 7155-TKV. One cycle is one open and one close. The battery itself usually needs replacing every two to three years.
Is battery backup required on garage door openers?
In California, yes. Senate Bill 969 has required it on residential openers sold or installed in the state since July 2019. Elsewhere in the US it’s optional.
Can I add battery backup to my current opener?
Only if it was built for it. Battery-ready LiftMaster models such as the 8550W, 8360 and 87504-267 accept the 485LM battery. Other openers need replacing to get backup.
Do battery backup openers work with Alexa?
Genie openers with Aladdin Connect, like the 7155-TKV, work with Alexa and Google Assistant. LiftMaster and Chamberlain myQ openers don’t have native Alexa or Google support.
What happened to the Chamberlain B6753T and B970?
Both are discontinued according to Chamberlain. The B4613T is the current Chamberlain pick with battery backup, and the LiftMaster 87504-267 covers the built-in camera option.
Will my opener still work if the backup battery dies?
Yes, on normal power. A dead backup battery only matters during an outage. Replace it when the opener warns you, and test it once a year by unplugging the opener and running the door.
