How long would a Battery Backup UPS run a Aquarium Filter for?

I was looking into getting a battery backup UPS for my aquarium incase power goes out… However, I was looking at the specs of some, and i found this one: http://www.newegg.com/Product/Product.aspx?Item=N82E16842117004
I need to know, aproximately how long this will run my aquarium filter, and air pump for? I have a AquaClear 50 Filter, and my air pump only runs on like 3 watts or less.
Anyone have any ideas?

not very long… but its alright. your tank can last a long time without anything working, if its to cold then wrap the tank in a blanket. your filters can be off for a couple of days without your fish being affected, even if you have saltwater then go to your local fish store and get a $10 battery powered air pump.\
hope this helps, a couple years back i was trying to find a backup system and went this way instead.
the duration of the emergency power depends on the ampere-hour rating of the battery given in AH. most batteries used in these things usually have a AH rating of 4. that means the battery can give out 1 ampere for 4 hours or 4 amperes for 1 hour. at 12 volts that usually translates to 48 watt-hours. I’m not familiar with the power requirement of your aqua clear but lets assume its 10 watts plus the 3 watts of your air-pump gives you 48 /(10 + 3) = 3.7 hours theoretically assuming my assumptions are correct. any way, this is very a simplified way of putting it. to get to the point, you can extend the working time by installing larger batteries or additional batteries but it’ll have to go on the outside and you’d probably void the warranty. to add, you simply have to connect the extra battery in parallel minding the polarity of course. however, be warned that whenever you tamper with an electrical appliance there’s always the danger of electrocution. please be careful if you intend to do what i just described. i only offered this for informative purpose only and do not advise you to do it. take care.
