Yes the NiMh battery pack is included and can last up to 3 hours talking. There is a battery indicator on the top of the unit. It glows green for good, yellow for medium, and red for low. This unit is great and I love at&t; service.

It has a battery backup in case the power goes out but not sure how long that will last for

Yes, there is built in backup. I don't know how long it will last, but definitely long enough for the typical power outage. Mine has been unplugged for over a day now and the display is still working (unlike the timer itself, which is permanently off, and ready for recyling).

Not that I'm aware of, I just had a power outage yesterday and the unit remained off

No, there is no battery back up. Even still, it's a great unit, and we've had no problems with it.

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

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

Absolutely, and it was tested as we recently had a several hour power loss and it had the correct time when the power came back on. 3 AAA batteries power it. It's a great unit.

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.

I don't believe so. There is no battery back up. I haven't experienced an outage with it running, however. So if it were plugged in and turned on, it might just come back on.

NO. I have it plugged into my computer battery back up so I can use it when the power goes out.

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.

The battery is a backup in case of power interruption. From a practical viewpoint you need a low voltage power supply.

Yes there is a battery backup. You do not lose the program, however the sprinkler will not work without power.

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.

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

Gee I bought it awhile ago now and it plugs into an outlet, but I checked the description on Amazon and it doesn't say there's a backup battery. There is a little red light though, so if it were to turn off, you'd know it is not working.
