Online or at electonics or home retail stores are probably best. What are you looking for since UPS batteries are very expensive if you need one that lasts
You won't be able to return them if you buy at Amazon because they're batteries.
I get mine from Best Buy. The first Cyberpower that I got in 2008 just died. It had a good, long run, and I'll buy that brand again.

Ah thats not going to need a really big UPS then but will that interruption cause any issues?. We used to have 2 hour cuts once or twice a week and i had to manually oxygenate the water at times.
How do you calculate run time? I was checking out the below power supply and was trying to figure out how long it would last for a 15 watt air pump.

Add the wattage of all pumps. Then get the respective UPS. Might very well be one of the smaller ones. Sounds like time is not an issue, for you wattage makes your choice.
For those who are interested in run time on batteries: the higher the Ah (amp-hours), the longer they'll run. This is not a primary focus of a UPS for computers, won't be posted on the box, but you should be able to find it in the product's specs online.
