Does this have a battery back up incase electricity is off?

This unit is predominately used for rv's or a 12 volt trailer that needs to monitor propane leaks. Most rv's have batteries used for boon docking when electricity isn't available. To answer your question NO it doesn't have its own battery!

No, it depends on the trailer's 12V system supplying power. If the trailer is plugged into AC or if the battery has sufficient charge this will be available.

This operates off your 12 volt coach battery. So as long as your coach battery has a charge, the device will work. This does mean however that you need to disconnect your coach battery when the RV is not being used for long periods of time. Otherwise the coach battery will go dead.

The unit is powered across the 12volt dc output of the converter which is connected to the battery terminals, consequently if you lose ac power to the converter the propane monitor is still being powered by the battery.

No it doesn't have a battery backup It connect to the RV (12v ) system, I hope I would never need a backup for that system. This LP detector is MUCH better than the OEM detector. I bought my motor home 12 years ago and had three LP detectors in it before I bought this one. The others 'died' after two to three years. I have had this one for more than 4 years and it is still going strong.

This radio does not have battery backup. If you have the radio set to get the time from the internet and you have wifi signal (or you are using Ethernet) the radio will automatically keep the time. If you unplug the radio or the electricity goes off, the radio will have to reset the time, date and so on. The radio will reboot and do it's setup thing when the power comes back on.

If you unplug, timer has a rechargable back up battery inside incase power out or disconnected by accident, to save the same setting.

Yes. It has a battery and I have used it both ways which is the reason I bought it. If I need to use it without electricity I can just as well.

This timer has a built-in battery. It will retain it's settings after a power outage.

Not that I know of. Anything plugged in has a battery back up. I am in an area of frequent power failures. More than one a month and it has not been a problem with the security system. You could call GE, I think it is GE/Jasco for the security system. Sorry I don't have the number with me. They are very helpful.

No, must be plugged in to operate....there is a "back-up"battery for the clock/alarm only.

I think it has battery backup. I don't remember, as the unit is with my mom at her assisted living facility.

Yes it does. I've had a couple of power outages and it has always come back up to my settings.Tom

It will not operate without electricity. It will restart at preset settings when power is restored.

It does have a battery back-up so if the power goes off, it keeps your programming.

Yes. Word of warning...if the power goes out, you will need to reset the timer. Also, this product lasted about one year and died on me. Did not replace with another. Went to Lowes and bought one that is digital and has battery backup ($25) seems to work great, but time will tell

Yes, it does have a battery backup. It works great, as i've turned the circuit off several times during our remodel and no power loss to the timer. All the times and programs remain correct.

I believe this unit does have a built in battery back up to maintain its' setting. The lights and optional audio warning do not function without power, but the setting will be retained until the back up battery is drained. Also, the video recordings on the SIM card are not lost with a power loss. Hope this answers the question.

No it does not. It only powers on when u turn it on and it actually shuts off if you don't use it for a period of time.

If it is plugged in to AC. Mine is not using battery backup and if the power goes off, the unit goes off.

No, it does not. When the power does out, it turns off. When it comes back on, it goes to the setup you programed. If the power is out for a long time (not sure how long) it will reset the time and not record unless you have it programed to record always.
