Does this have a battery backup?

It has a battery for memory back up, but it runs off the C wire. Be sure your thermostat setup has a C wire.

Yes. It's a smallish, flat, mercury cell looking thing. It lets you take it off the wall momentarily and not lose the settings. I guess it would do OK in a power failure.

Yes, it does. It has a battery backup (9v) to keep programmed numbers and the message stored during any power outage.

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.

It does come with an AC charger and battery backup. We used ours for over three years and had no problems. Power did fail occasionally and the battery took over.

Mine came with the battery as well. There is a removable battery so if you want a backup it is possible.

No there isn't a secondary battery back up. However there are 4 AA batteries that saves the memory.

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.

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.

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

No battery backup as the other responses indicated already. It's worth mentioning that there is some sort of memory function so that it "remembers" the temperature setting when the power does come back on.

Yes it has a battery back-up for both units. I do not know about dual voltage. In response to others, i do not have a problem with volume and the unit has incredible range.

No battery backup. Be sure and have a cellphone as a backup for power outages, Regular phones normally work with power outages, these don't.

No battery back-up. If you lose power you have to release the emergency release and open the door by hand.
