That all depends; some manufacturers offer that option.

For older installations of types that did not have or offer the optional UPS, one could easily buy and install an after-market uninterruptible battery supply.

In the event of a power outage and there's no battery back-up supply or a back-up generator to power your electric door opener, simply release the emergency handle and lift the door manually; of course that's predicated you're able to gain access to your garage.

Battery is bad. I removed it and garage door opener is still beeping. It is driving me crazy. Help

as long as garage door is powered(plugged into outlet), then with a removed battery backup or a bad backup battery, the unit will beep to alert you to the issue. replace the backup battery with a new/good one.

How to open the door if no electricity

Almost all garage door openers have a switch mechanism that will allow you to open the door manually. It is usually a pull cord on the motor or track. Pulling it down usually deactivates automatic mode. Just pull it up into position when the electricity comes back on.

Alarm on garage opener is going off

Do you have a model with a battery backup on it? The battery, like most batteries, eventually wears out and will start beeping. If you don't have frequent power outages in your area, or have another way to gain entry to your home if there were a power outage, (like an old fashioned key), locate the battery which is approximately 4"x5" located on the outer side of the opener motor head, unplug it and forget about it. This would get rid of the beeping noise. Or you can replace the battery.

I ahve a beeping sound that is coming from my garage door opener.

If you have an opener with battery backup this may help. BBU stands for 'battery back up.'

This is battery related. On top of your unit is a battery pack with three colored led lights. You can tell what is going on by looking at these. This information is in your manual or here it is.
GREEN LED: All systems are normal. A solid LED light indicates the batteries are fully charged. A flashing LED indicates the batteries are being charged. NOTE: Batteries do not have to be fully charged to operate the motor unit. YELLOW LED: The motor unit has lost power and is operating off of the BBU. A solid LED with beep, sounding approximately every 2 seconds, indicates the motor unit is activating the door and is operating off of the BBU. A flashing LED with beep, sounding every 30 seconds, indicates batteries are low. Once the power is restored the BBU will recharge. This is indicated by a flashing GREEN LED. RED LED: An error has been detected and the BBU will automatically shut off. The BBU will attempt to restart by reconnecting to the batteries. If the error is still present it will shut itself off again. This process will repeat every 5 minutes or until the error has been resolved. This is used to prevent further draining of the batteries. If a red LED remains on when the power is restored, and is accompanied by a beep sounding every 30 seconds, please call for service.

My garage door opener beeps frequently but operating well. What is the issue & how can i resolve?

Sounds to me like your backup batteries are low. The back up batteries are there for use should you use power. You can try this -
  1. Unplug the garage door opener.
  2. Get into the back up battery compartment.
  3. Now unplug the connector to the battery pack and replug it in. This might help but if you continue to have this beeping then you will have to replace the backup batteries. You will not suffer any mechanical problems unless your electricity goes out.
