To keep fish alive... you want to at least be able to keep the pumps running for up to 2+ hours. My central air pump runs at about 100W, therefore my battery backup can keep all of my tanks on "life support" for about an hour or two before the backup power runs out. If your setup is smaller than mine, you can probably squeeze out way more time than I can.
These are specially designed for fish tanks.
