Imagine being home late in the stormy night and it is pouring, the lamps on your street have fluttered one or two times and as you turn into the drive the electricity goes off. No lights, no heating, and no possibility of the garage door opening at the touch of a button. You are left out there with no backup. It might seem like a small inconvenience until you are actually in that situation. It is at that point that you become aware of how much you are dependent upon a system that you hardly give thought. 

What would happen when there is a power outage? 

A garage door opener nowadays uses all mains electricity. The lights, the sensors, the motor, all of these are reliant on it. When the supply is discontinued, the system becomes as heavy and as a locked barrier. Yes, there is the manual release cord, but when you use it, you have to raise the entire weight of the door yourself. That is not an easy task to many people. It may not be possible to children, older adults, or any other person with limited strength. 

And power outages do not come in a nice way. They arrive in winter storms, on hot summer afternoons, occasionally without any notice, in the middle of a regular day. A battery backup means that the door will open and close, but quietly until the mains is restored. 

What is the way a backup works? 

The opener has a rechargeable battery inside which is charged when the power is flowing normally. Once the power cuts, the battery automatically kicks in. There is no switch to flick or button to press. It is possible that you do not even realise the change until you realise that the rest of the house is dark. 

The majority of systems offer sufficient power of approximately 20 to 30 cycles. That is sufficient enough to get in and out within a couple of days even when the outage is protracted. There are batteries that have a higher duration of life, but it is not about endless running. It is all about filling in the gap, maintaining access when you need it the most. 

Do you really need it? 

It is the question that most homeowners would ask when they are buying a new opener. In case you are living in a city where the infrastructure is stable, perhaps there are few power cuts. And failures still occur even in towns where the grids are strong. A burst transformer, a tree downed, roadworks miscarried, it just takes one. 

In the rural homes the case is even more obvious. Lines run through fields and woods, which are more exposed to storms. A backup is not a luxury in those places, it is almost a necessity. 

And there is the question of time. It is not the annual outage at noon which catches you out. It is the one that catches you off guard at night or when you are already late or when the garage door is the only entrance to the house. 

Convenience is not as important as safety. 

Consider families in which the garage is the principal entrance. After school children walk in that manner. Parents arrive home with shopping bags. In case of power outage and the door is stuck, it is not possible to enter. That can be hazardous in the case of an emergency. 

Animals can be locked in as well. That gets serious in summer when it is a hot garage. Battery backup ensures that the door is always able to move, be it to allow people to enter or exit. It is one of those things that you hope you will never need and when you do, it is priceless. 

What is their service life? 

Batteries don’t live forever. The majority will require a change after every three to five years. The symptoms are typically obvious: the reduced number of cycles, the reduced speed of movement, the warning lights on the opener itself. It is not a very big expense and changing a battery is much easier than changing the entire motor. 

Maintaining one in a good condition is largely automatic. The battery will remain charged as long as the opener remains plugged in. Other homeowners check the backup by yanking the plug on the device and operating the door at least once a year. So they are sure that it will be ready when it matters. 

What about smart systems? 

Smart garage door openers have gained popularity in the recent years. They are linked to phones, they are compatible with home networks, and they even give notifications in case the door is left open. All that cunning is gone without power. The battery is a backup, but it does not only move the door, it maintains those smart functions alive as well. Status checking, still closing the door remotely, still getting alerts can still be done. To individuals who commute, it is not just convenient, it is comforting. 

Is it worth the investment? 

The additional price of a battery backup is different. It is either in-built in the opener or in some cases it is an optional add-on. Anyhow, it is a minor expense in comparison with the irritation of being locked out or the danger of being unable to open the door in case of an emergency. 

Consider the number of times that your garage door opens each week. Divide that by the number of weeks in the year, then the number of years you will possess the home. The power will run out sooner or later. The only actual question is whether you will be ready when it occurs. 

Garage doors are supposed to be a way of freedom of movement, of coming and going of everyday life. A battery backup does not make the door any faster or more attractive. It is not even noticed most days. The thing it does is to ensure that the biggest moving object in your house remains operational regardless of what the grid is doing out there. It is that dependability that is quiet that is making more homeowners opt to have it in the first place.
