Odd use for a UPS need help

I want to get a couple UPS's to cover my fish tanks. We been having a lot of problems with the power in my area, we've been losing power a lot, so I would like to get some battery backups for my fish filters, so there is nothing to have to worry about when the power goes out.

Now to my question. I know the filter's motor is using at most 15 watts. according to the book. I am trying to figure out runtimes on different UPS's. but im not sure if running the UPS with such a low load will do hurt the UPS etc. And since most UPS's are listed @ a computer load, how would you go about figuring how how long the UPS would last with only a 15 watt or under load on it while on battery.

Also since I really dont care about the protection part of the UPS, would say a UPS from a big brand vs a ups form a generic be the same for what I need it for? or will the runtimes be different even with same specs?

Thanks in advance for the help
 
KingKareu I believe does this as do I. Any decent UPS with AVR will suite you fine. As for runtime....if your pump is only a 15watt.....any 900va or so UPS will have plenty of runtime. I use a 1200 and I have never actual found how long it will last.
 
Great thanks for your responce. I just wanst sure how the UPS's would react to such a low load on the battery when its active.

No problem. If I were you I would grab a refurbed unit from refurbups or APC to save some money on it.

And just because I am nosey what filter/pump are you using?

I run a Rena FilStar xP3, and a Penguin Power Filter 350 for our little 47g tank.
 
Nice. We got a couple tanks setup. We have a 55g Planted tank thats running a Fluval canister, and our 45g community tank is running a Emperor 400 and a HOT Magnum canister. I think im goign to pick up a couple 1500VA ups's and see how it goes.
