Well,
I did a test running my air pump using the UPS and the 170aph gel battery and the air pump ran for 30 hours with no issues. The voltage on the battery drop from 12.6 to 12.3. That is more than I expected since is only for emergency situations

Now my next test will be using the workaholic u3050 (310aph) deep cycle battery to see how long can run the pump for emergencies. If this one works good, I am hoping I can use a charger and maybe a relay so it can switch to the battery when the power goes out.....
