is there a battery backup?

No there isn't a battery backup. The phone will still work during a power failure; you can dial out & receive calls, but the display will be blank & the other keys will not work until power is restored. Hope that helps!

You must supply a power source, so battery backup would be a good option to think about.

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

I am sorry, Douglas, but it has been over a year since we purchased this. I can't remember a back-up battery.

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

I do not know because I have not used that feature on our phone yet. I know there are no batteries for back up.

Regarding the questions about "battery" backup. I just spoke with P3 tech support. No, there is no battery; yes, there is a memory chip installed which stores recorded data. So no worries about leaking batteries...

I haven't had that problem, but if there's a battery backup that might need to be changed.

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.

There is a small "backup" watcg type battery but it is not a rechargable one. Although I am happy with this unit, I do not recommend it if you are wanting to use it without a power cord.

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

Yes it does. It comes with everything you need to hook up the backup system except a battery.

HiNo, it doesn't have battery backup system, I think you can use a battery convertor to convert 12v DC to 110 AC, I have such a device and haven't try it yet, will try this weekend.

Yes, once the unit has been plugged in and charged, it has a back-up battery that will preserve time and settings during intermittent power outages.

As far as I can tell, there is no way to back up data as there is no output to any storage device. But....it does have flash memory so that you don't lose data during battery replacement.
