I'm looking for a backup battery that I can plug my surge protector into. I currently have my aquarium stock biocube lights, 300w heater, 2 x nero 3 powerheads and the stock biocube pump plugged into my surge protector. Not sure what's common as far as backup systems are concerned in the hobby, but I was hoping to plug the surge into a backup. Additionally, I'm not quite sure what I should be expecting as far as how long a typical backup battery holds charge for during a power outage. What are the common brands/models used that support several devices? Any suggestions would be appreciated.
