Here is what I use. It's a sealed lead acid battery I obtained
from a power plant. They use them to back up there computers
and periodically replace them whether they need to or not.

I bought the case from Wal-Mart and added the connectors
to match my power supply.

My power came back about 4am. I sat here in the dark and without a scanner
to listen to. I never had or even thought of a battery back up for my
780's.
My utility company, PSE&G, is on a 900mHz trunked system so I had no way
to
monitor them. lessen learned, GET A BATTERY BACK UP!! I am so mad at
myself
for not doing this from the start..
anyone out there have a nice battery back up source? I am open for ideas,
please pass them along.
thanks
Anthony
