hit up any computer store right now, UPS are very common for PC/workstations. The bigger the wattage the longer it will last so oversize if you can. I can run a few pumps for hours with no issues. Put a cheap CFL just to maintain light cycle. The knockoff brands have less reliable batteries so run the manufacturer's suggested test on them every few months and time how long they actually last.
