Can't recall. We since have replaced the unit because it failed in less than a year. Can't recommend this.

I bought six of these and I didnot have to reprogram them when the light when out. Now, the light went out for 5-10 minutes. I would say that it have an internal back up battery or memory. I just haven't been able to test it with out any power for longer than 5-10 min. I hope this help. I really like them. They look cool too.

It must have some sought of memory chip, I never had to reset after power outage

it does not have a battery backup, but "Power outage: The screen is blank. Only the time must be set if the outage lasts more than 4 hours; all other settings and programs are permanently saved." This is from the direction sheet. I do like the unit!

This device uses Permanent Memory without Battery backup. I have cycled the power several times in the 8 months or so I owed it and it holds the settings just fine. Modern memory Integrated Circuits hold their memory state without Battery power.

Yes has a battery backup. Can be connected with a case by connecting with the lightning charger cable.

No battery backup. Instructions say battery not needed and settings are saved in memory. Unit works great for me. I love that it's really easy to program and use

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.

No,There is no battery back-up, but it is very easy to reset time . The unit has saved me a lot of $$$$$ .I have my hw heater set to come on 2 hours a day.

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.

Yes. It has two timer modes you can set, for example one for morning and one for evening. These are the two LEDs beneath the LCD clock display. However, there is no battery backup when the power fails but setting the timer is very easy. We use this feature in the morning to save time.

It does *not* have a battery backup. Some settings survive a power outage, but some do not. For example, the setting to *not* go into power saving mode is not preserved; the "standby" mode - you have to reset the "standby" power level whenever the power comes back on - to disable that feature is you set the "standby" power level to 0 (zero) watts. The option to turn off the PIR motion detection feature does keep its setting when the power is restored. I don't know what happens to other settings that I do not change from their default values.

Yes it has a battery backup. All in all good radio with great sound and very easy to pair the bluetooth. Only thing I dont like is the small display and the narrow viewing angle, and the fact it came with no instructions at all

Yes there is a backup battery. Since I have had no problems with the chair, I am sorry to say I haven't even thought about what I would do if it needed service.

Yes it does. Bought it for my younger brother in law and he loves it. Only thing is ours didnt have a battery pack so he leaves it plugged in all the time.

Yes, it comes with a battery. You'll need to purchase an SD though. I purchased a 2nd battery to have a backup though I haven't had a problem with the battery life at all b

Yes to your first question. As for the battery back up timer I haven't seen one of those.

Yes, mine came with a backup key in case the battery dies. So far I've had no issues at all with this.

No it does not. Ac power plug only and batteries for backup in cast of a power failure. I believe the battery backup is good for about 8 hours. We are very please with this product. As I said before, it is a little tough to get the timer set right ( of course I am pretty dumb when it comes to these things ) but once it is working, you will almost forget about it.
