Are you planning to add a battery backup for OBI devices?

The following devices are connected to my Back-UPS 550 http://www.amazon.com/APC-BE550G-Back-UPS-8-outlet-Uninterruptible/dp/B0019804U8 (Shipping Weight: 13.7 pounds):
- Cable modem/router/wifi
- Another router
- Obi200
- Panasonic phone base station
I was disappointed that this UPS lasted only 45 minutes in my test.
I recommend buying a larger UPS or supplementing similar UPS with an external battery.
Those small UPSs are only designed with a typical runtime of 7-15 minutes. The intent was that they'd give you enough time to save your work and then shut down. You're asking it to do something it wasn't designed to do. Yes, for extended runtime, you need a much larger battery, or a generator.

As other had said, I connected the OBi's, cable modem, router & switches to a 1500VA UPS so my home phone lines was never disrupted by power outages.

1500VA specifies the maximum power that the UPS can provide but says nothing about the length of time it can do so.

I didn't know exactly the time it provided to run the OBi's and the DECT 6.0 phones connected to the UPS because I also connected other things to this UPS such as desktop PC + monitor & a 15" laptop. But even with all these, it lasted for a very long time.

I have a friend, BTW, who is running his OBi200 off a 12.6V trickle-charged battery. So far, it's run fine.
A Lead acid battery can be 13+ volts
would you recommend using a linear regulator?
or a 12V Step-up/Step-Down Voltage Regulator?
