Are There Batteries In Garage Door Openers? Why?
The question was originally asked here on Quora.
There were already six answers to the question but I felt I could add to the answer.
Many of the openers now sold, whether they be from Genie, Liftmaster, Linear, etc. have a battery option.
The battery allows the opener to work even during a power outage.
This is important for elderly and disabled people.
If they have an emergency while there is a temporary power outage.
(How often are there power outages? How often do you have an emergency where you have to leave the house while there is a power outage? And if you can't lift the door yourself should you be driving yourself?)
Garage door repair companies love these batteries and try to stress the positives in them by playing people fears.
They do this because when the battery dies the homeowner will often call the company they got the opener from for a new battery.
The new battery with the service is usually over $100.
And the batteries go bad every two years.
The opener seems to know when that particular battery was installed, and in exactly two years, starts emitting a loud sound like that in a smoke detector.
A very annoying sound that can't be ignored.
(Not appropriate for something so minor as a garage door opener in my opinion.)
So the garage door repair company gets repeat business every two years exactly like clock work.
Easy pure profit for little more than driving to the customers residence and picking up as much as a couple hundred dollars.
Now does the homeowner really need battery backup?
That's an easy question to answer.
Just ask the homeowner if they have any problems opening or closing the door by hand.
If it is not an issue for them then they certainly do not need the battery!
Unless the customer likes the idea and realizes they will be out $100 to $200 every two years.
Then it is morally OK to take their money.
However, I feel the opener should be as simple as possible, the less to go bad the better, and so should only open and close the door.
Gimmicks like batteries, internet connections, lights, safety sensors, etc., are more things to go wrong and lessen the lifespan of the opener and should therefore be avoided.
Naturally each vendor's battery system is slightly different.
You will need to consult the vendors manual to determine what the beeps mean and how to replace the batteries.
A few garage door openers have tricky battery compartments and hook ups that might have been put in to make it difficult for the owner and encourage the them to call a service tech.
Yes, I'm very cynical about anybody actually needing batteries.
If they are in such bad shape then they would have a helper or caretaker.
The caretaker should have no problem opening the door by hand...
Again making the battery totally unnecessary.
