If the battery is disconnected, will this opener still work, and will it beep every 30 seconds like it does with a low/dead battery? Thanks!

When I first installed mine I did not put the battery in right away. It did not beep at all. Hope this helps answer your question.

Good day J. Martin. Thanks for your message. Well actually installing the battery was the last thing i did after i wired it up and ran some juice through it from the house. No beeps or anything with the battery out.

Yes it will work if the battery is disconnected. Unsure about the beeping but I do not think it does.

Not sure...I had a problem with my 15 year old Liftmaster, and tried to replace the receiver, but that didn't work....the frequency was wrong, or whatever....then I needed a transformer......and was getting nowhere......so eventually I replaced the entire garage door opener....so no more problems. I should have realized that there was a problem, when the yellow LED on the old unit started blinking....I ignored it and then the remotes wouldnt work....and I returned the receiver for a refund.

Yep, it beeps once when u arm it, and beeps twice when u disarm it. Assuming your in range. So u could toggle back n forth to locate it. It won't sound twice hitting the same button, but u can lock and unlock unlimited times, and listen for the beeps. It's more of a beep than a chirp, and again newer battery sounds off louder than a weak one. FYI, I replaced my battery about 2weeks ago, and has not dropped in strength yet. Battery that came with was not very good, malfunctioned after bout a week using it. I replaced with a duracell, and works much better and longer. Hope this helps. Range on the remote is pretty good, liken it to a car lock, works at about the same range. Yep, it beeps once when u arm it, and beeps twice when u disarm it. Assuming your in range.

Mine didn't work with my opener. The red smart button didn't do anything but might be a bad card in my opener.

Mine was 3 yrs old when I had to replace the battery. My other garage door opener is still going strong after 4 yrs on the original backup battery. Hit or miss I guess.

The gate opener works very well on AC voltage alone. The use of a back-up battery is useful if one lives in an area of frequent power outages.James B.

You have to move it for the alarm to trigger. Opening the door won't do it, but closing it will. You can adjust how sensitive it is, and how long it takes to arm after turning the key. So if you move it, it will start beeping and if you don't disarm it, it will trigger the alarm. Don't know how long the 9V battery lasts, because I just got mine a few weeks ago.

One more little helpful hint though...don't leave it ON or it WILL go dead a lot quicker! Found that I had done that last night when I had a dead battery and was like, no big deal...I have my handy jumper...which I then found I had left on and was dead! My bad! :P

Maybe this reading might help a little, http://www.garagerepairutah.com/garage-door-opener-open-close-problems/ Door openers know their state, and it's not based on the eye sensors or anything like that. When you click the button on your remote, the entire assembly knows if it needs to open, or to close, or if it is in the middle of one of the operations. I can assure you from hundreds of customers using this specific button that is internet connected, their phones know quite positively the status of the door. It updates and even shows confirmation once it is in that other state. If you're on the fence about getting it because you just don't understand how it works, go ahead and get it and let it surprise you!

Make sure the battery is not in backwards. If that is not the problem then you might need a new remote. Try contacting chamberlain customer support and explain the issue. If they can't get it to work then they should send a new remote since the opener is still under warranty.

You would think it would just run off the power going to the opener. I assume its for the light that lights up the buttons when you open it up.

The unit comes with a backup battery hookup - just make sure it isn't stored inside and has working AA batteries. The door is supposed to beep when the batteries are starting to get low as well I believe. I have only had it for a few months and cannot verify this, though.

Just purchased the botvac 80 about three weeks ago. I have used it four or five times now. I have never heard it continuously beep. This thing is amazing, it works great!

sounds like you have a broke logic board closer inspection needed maybe a trace or two (solder connections broke)...how old is the unit determines whether to buy a new opener...in my opinion

No, the opener will still not function due to the lack of light sensor. But you can buy replacements at Lowes on the cheap

It varies. My battery actually died 3 months in but eventually recharged and started working again. It's an on an off thing and right now, it's all off. It might be better to connect your alarm to the main battery.

Yes. Your opener will function normally while the battery back up has power.
