You mean deep cycle battery? very important that we use the correct terminology.do what I did.
get a +-600w ups (+-30min)
1000w inverter or bigger
12vdc car battery (the bigger the capacity the better)
connect ups to mains & pc / laptop as normal
when power goes off - connect inverter to 12vdc battery
unplug mains from ups
connect inverter to ups mains input
the power from the ups is good enough for your pc / laptop etc.
my 12vdc 105amp battery gives me +-4hrs and I run my tv lamp / CRT tv / media player.
