In our years serving Burgaw, we've seen this problem again and again: a storm knocks out power, and homeowners are suddenly locked inside or outside their garage. A battery backup system on your garage door opener prevents exactly that scenario. Without one, you're dependent on grid power for basic access to your home.
Most garage door openers rely entirely on electricity. When the power goes down, so does your ability to open or close the door. You can't get your car out. You can't get inside. In winter or during storm season across Pender County, this isn't just inconvenient. It's a genuine safety hazard.
Battery backup systems solve this by storing power in a rechargeable unit attached to your opener. When electricity fails, the backup kicks in automatically. You retain full functionality for several cycles (usually 8 to 12 openings and closings) before the battery depletes. That's enough to get you through most outages in Burgaw.
The system charges whenever your opener is plugged in and operating normally. It's a passive safety net you won't notice until you need it. When power drops, a sensor detects the loss and switches the door to battery power. The backup doesn't run your lights or garage heater. It powers only the motor and control board.
Most battery backup units last between 3 and 5 years before needing replacement. The cost of a new battery module ranges from $150 to $300, a small price compared to being locked out during an emergency.

Many homeowners confuse battery backup with smart openers. They're separate features. A smart opener (like MyQ technology) lets you control your garage door remotely via your phone. It requires internet connectivity. A battery backup provides manual operation when power fails. You don't need internet. You don't need your phone. You just need the backup battery charged.
You can have both. A smart opener with battery backup gives you remote access plus emergency functionality. But if you're choosing between them and budget is tight, battery backup is the safety priority. Remote access is convenient. Emergency access is survival.

Battery backup systems are straightforward to install on new openers. They're also retrofittable to many existing units, though compatibility depends on your opener model and age. Older openers (more than 10 years old) may not support battery modules.
Installation takes about 30 minutes. Our team at Burgaw Garage Doors can evaluate your current opener and either add a battery backup or recommend a replacement unit with backup already integrated. Schedule a free estimate today to see which option works for your home and budget.
Maintenance is minimal. Check the battery annually (most systems have indicator lights). Replace it every 3 to 5 years. Keep the unit clean and dry. That's it.
Last winter, a Burgaw customer experienced a power outage during an ice storm. Without battery backup, she would have been unable to open her garage door for three days. Her car was inside. Her heating system relies on a garage outlet. With the backup, she opened and closed the door as needed during the outage. When power returned, the battery recharged automatically.
That's not a luxury feature. That's peace of mind backed by actual performance.
You'll need a manual release. Most garage doors have a red cord hanging from the trolley inside the garage. Pull it, and you can open the door by hand. But this only works if you're already inside the garage. If you're outside or locked in, you're stuck until power returns or a technician arrives.
Manual release is a safety feature, not a solution. Battery backup is the real answer.
Battery backup modules cost between $150 and $300 for the part alone. Installation adds another $100 to $150 if you're retrofitting an existing opener. New openers with integrated battery backup run $300 to $600 total. Compare this to an emergency lockout call or being without garage access during a storm.
We offer same-day installation across Burgaw and the surrounding area. Contact us for a specific estimate based on your opener type and installation needs.
How long does a battery backup last before I need to replace it? Most battery modules last 3 to 5 years. After that, the charge capacity drops, and replacement is necessary. Indicator lights on the unit show when replacement is needed.
Can I add battery backup to my old opener? It depends on the model. Openers older than 10 years often aren't compatible with modern battery modules. We can assess your unit and advise whether retrofitting is possible or replacement is better.
Will battery backup work if the power goes out overnight? Yes. The backup charges whenever the opener is plugged in. It stays charged passively until needed. One full outage cycle won't drain it completely.
Does battery backup require internet or a smartphone? No. Battery backup is completely mechanical and electrical. It needs no internet, app, or phone connection. It works during total network failure.
How many times can I open my door on battery power? Most systems allow 8 to 12 full cycles (opening and closing) before depletion. This typically covers most residential outages.
