Does it have a Battery Back up for those time the power goes out in the middle of the night?? Like a 9V battery to keep it going when power is out

No battery pack. Your phone is the clock and is charging while attached to Hale dreamer. If you lose electricity, your phone stops charging, that's all. I hope this helped.

Yes. It has dual alarm clocks. Also, although I'm not aware of it having a battery, every time the power goes out (for several days recently), it maintains the time, even though it doesn't function. Kind of a nice feature for middle of the night power outages - the alarm still goes on in the morning!

Not battery operated. Does have battery backup, in case electricity goes out.

Usually this light has a dedicated feed which keeps the battery fully charged. If you wire it or feed it through a switch, it would wise to make sure that nobody turns the switch off. Remember that this light is designed to work when there is a power failure and will usually work only for four to six hours after a power loss.

I accidentally left it on overnight and discovered it doesn't have an auto-shutoff, but the batteries were still going strong. My guess is it uses very little power.

No they don't have battery back up. They are great though and I now have them in every room of the house running baseboard heaters. With the exception of the one running the gas fireplace. Battery back up is usually found in the programmable thermostats so it will save your settings in the event of a power outage.

Yes, the timers have a battery backup to retain your settings in the event of a power failure. The battery is charger when you plug the unit into an outlet. Let it charge for at least 10 minutes before unplugging. I'm not sure how long the unit will keep the settings stored during a power outage, but I have experienced a outage of about 2 hours and mine retained its settings. Hope this helps.

Yes it does. All is set to go. Has to be hard wired by electrician and the battery powers the light when the power goes off. Very nice light for the money.

No. It does not have battery backup. During a power outage, it will need to be manually disconnected to allow opening or closing of the garage door.

The power supply is an option. It uses a 9 volt battery (not supplied - no surprise there). When the power supply is used, the battery functions as a back-up.

Unfortunately, this model does not have a battery back-up. So if you turn it off it will reset to the default mode. If you think a bright light will kill the mood imagine a bright light along with the loud announcement of: "You Are Trespassing!!!!" Scared me to death the first time our power failed. There are other similar models that do have a battery backup so that it will not reset/loose any video when the power is cut. Good luck!

It's just a backup battery if your power goes out, as far as i know its not just for certain versions of windows.

No. The only light on it is a light to warn you when battery power is getting low.

the battery is for backup only..... in case electricity goes out. You still need to wire it.

A wire. I can't remember if it took batteries for back up if the power went out. It's been a while since we had it.
