In our years serving Alamance, we've seen this problem again and again: a power outage hits, and homeowners get trapped in their garage or locked out of their homes because their opener won't work. Battery backup solves this, but it's not always necessary for everyone. Here's what you need to know to make the right call for your home.
A battery backup unit attaches to your garage door opener and stores enough power to open and close your door about 20 to 30 times during an outage. When the electricity cuts out, the battery kicks in automatically. You can still use your remote or wall button to operate the door, giving you access to your vehicle and home even when the grid is down.
The cost ranges from $300 to $600 for the unit and professional installation. For most homeowners in the Alamance area, that's a reasonable investment if outages happen regularly. However, if your neighborhood rarely loses power, it might not be worth it.
You're a good candidate for battery backup if any of these apply:
Your area experiences frequent power outages (more than twice a year). You work from home and need reliable garage access for vehicles and deliveries. You have an attached garage where being locked out means losing access to your home. You live in a rural part of Alamance or nearby communities where power restoration takes longer.
If none of these fit, you can skip it. The battery backup doesn't protect your home from break-ins or add any security features beyond convenience. It's purely about keeping your door operational when the power fails.

Don't confuse battery backup with smart opener technology like MyQ. A MyQ-enabled opener lets you open or close your door from your phone using the internet, but it doesn't work if your power is out. Battery backup is different. It's a physical power reserve, not an app feature.
If you want both conveniences, you can add battery backup to a smart opener. That gives you remote access when power is on and manual operation when it's off. It's the most flexible setup, but also the most expensive option.

Battery backup units need professional installation to work safely and pass inspection. Your Garage Door Alamance technician will connect it to your existing opener and test it under power-loss conditions. Most units come with a 3 to 5 year battery warranty.
The battery itself degrades over time. After 5 to 7 years, you'll likely need a replacement battery, which costs $150 to $300. Plan for that expense if you decide to install one now. Regular maintenance of your opener itself keeps the backup system running smoothly. If you haven't had your opener serviced recently, now's a good time. We offer free estimates for opener troubleshooting and repairs to pinpoint any issues before they become bigger problems.
Installation: $300 to $600. Replacement battery (after 5 to 7 years): $150 to $300. Monthly cost over 5 years: roughly $5 to $10 per month.
Compare that to the cost of being locked out of your home during an outage. A locksmith service call runs $100 to $300, and that's just one incident. If outages happen twice a year in your area, battery backup pays for itself in three years or less.

Ask yourself: How often does power go out in my neighborhood? How much would it cost me to be locked out or unable to access my garage for a day? Is the convenience worth $5 to $10 per month? If you answer yes to two or more, battery backup makes sense for you.
If outages are rare and you have alternative ways to access your home or vehicle, skip it. You'll save money and avoid the battery replacement hassle down the road.

Q: Will battery backup work if my whole garage door opener fails? A: No. Battery backup only works if the opener motor itself is functional. If the opener is broken, the battery can't fix it. You'd still need repairs to get the door moving.
Q: How long does the battery last if I use it during an outage? A: Most batteries provide 20 to 30 full open/close cycles. If you open the door twice a day during an outage lasting several days, you'll run out of power. It's a temporary solution, not a permanent backup.
Q: Can I add battery backup to an old opener? A: In most cases, yes. As long as your opener is still functioning, we can install a compatible battery backup unit. Older models sometimes have compatibility issues. We'll check yours before quoting.
Q: Do I need battery backup if I have a smart opener? A: Smart openers without battery backup stop working during outages because they need internet and power. If you want remote access and outage protection, you need both the smart feature and the battery backup.
Q: How do I know if my area has frequent outages? A: Check with your local power company or ask neighbors how many outages they experience per year. If it's more than two, battery backup is worth considering for your home.
