In our years serving Onalaska, we've seen this problem again and again: the power goes out, and suddenly homeowners are trapped with a non-functional garage door. A battery backup system solves this. It keeps your opener running during outages, lets you exit safely, and costs far less than you'd think. Whether you need one depends on your situation, local weather patterns, and how often the grid fails in your area.
A battery backup unit sits between your opener and the wall outlet. When power cuts out, it kicks in automatically and provides enough juice for 10 to 20 full door cycles, or roughly 4 to 8 hours of intermittent use. You won't run your garage lights or charge your phone from it. The battery powers only the opener motor and the safety sensors that prevent the door from crushing anything beneath it.
This matters during ice storms, windstorms, or maintenance work on the power lines. In Onalaska and nearby Lacey, winter weather can knock out electricity for hours. Without backup power, you're either manually lifting a heavy garage door from inside (dangerous and exhausting) or calling a technician for emergency service.
Many homeowners confuse battery backup with a smart opener like MyQ. They're different tools. A smart opener lets you open and close your door from your phone, set schedules, and receive notifications. Battery backup keeps the door functional when the power fails. You can have one, both, or neither.
For most Onalaska homes, we recommend battery backup over a smart opener if budget is tight. A smart opener is convenient, but a dead battery backup is a genuine safety hazard during emergencies. Check out our detailed comparison of belt vs. chain vs. smart openers for a full breakdown of what each type offers.

A quality battery backup unit runs between $300 and $600, depending on the brand and capacity. Installation takes 30 to 45 minutes. Some openers come with battery backup built in, which costs slightly more upfront but eliminates the need for a separate device.
Replacement batteries typically cost $100 to $150 and last 3 to 5 years. That's a minor expense compared to being locked out of your garage during a winter emergency or paying premium rates for same-day repair calls.

Ask yourself three questions. First: does your area experience regular power outages? Onalaska's grid is generally reliable, but severe weather happens. Second: do you have a manual release inside your garage to open the door by hand if needed? If not, battery backup gains importance. Third: are you home during most outages, or do you work away and need remote access?
If you answered yes to any of these, battery backup is worth the investment. If your power rarely fails and you have good manual access, you might skip it and put that money toward proper garage door maintenance instead.
Battery backup units install cleanly behind your opener. A small plug goes into the wall outlet; the backup unit plugs into it. Most systems include a small LED indicator that shows whether the battery is charged. No wiring or complex setup required. We handle installation at Garage Door Onalaska and test the system before we leave.
One important detail: battery backup works only if power to the outlet is cut. If your breaker trips or the outlet loses power, the backup activates. If the garage door opener itself fails, the battery won't help. That's why keeping your opener well maintained matters.
When the power goes out, the battery backup activates silently. You press your wall button or remote, and the door operates normally. The backup provides enough cycles to open the door multiple times and get vehicles out. Once power restores, the battery recharges automatically over the next 24 to 48 hours.
In longer outages lasting more than a few hours, you may exhaust the battery. That's when manual release becomes essential. Most openers include a red cord or handle inside the garage that disconnects the door from the opener, allowing you to open it by hand (it's heavy, but doable in emergencies).
Don't wait for the next storm to discover your opener has no backup power. Whether you choose to add a battery backup unit or stick with manual release, knowing your options ahead of time keeps your family safe and your garage functional.
Call us at 360-469-5039 or contact us online to discuss whether battery backup makes sense for your home. We'll provide an honest assessment and a fair estimate with no pressure.
How long does a battery backup last? Most systems provide 10 to 20 complete door cycles before fully draining. In practical terms, that's 4 to 8 hours of typical use, depending on how often you open and close the door during the outage.
Can I add battery backup to my existing opener? Yes, in most cases. If your opener isn't ancient, a standalone battery backup unit clips in easily. Some newer openers already include battery backup built into the motor unit, so check your manual first.
Does battery backup work if my garage door opener is broken? No. Battery backup powers only a functioning opener. If the motor or gears are damaged, the backup won't help. That's why regular maintenance keeps both your opener and backup system reliable.
How often do I need to replace the battery? Every 3 to 5 years, depending on the brand and how often your power fails. We recommend testing your battery annually and replacing it at the first sign of weakness.
Will a smart opener like MyQ work during a power outage? No. Smart openers require both WiFi and power to function. A standard remote works during outages only if the opener itself has battery backup. Smart features and backup power are separate features.
