    Hello,

    I have a pc UPS that I want to connect to my wavepump/return pump in case the power goes off and I am not home.

    The UPS is 1000va and 600W with 2 12v 7.2ah batteries, connected in series.

    The pump is only 20W.

    I would've thought that this should be fine for about 2-4 hours of operation, given the small consumption of the pump.

    As it is, I only get about 25 minutes on a fully charged, new UPS. I've heard of people getting about 4-6 hours on a similar consumption on a smaller UPS.

    Anyone with ideas or experience in this regard that can assist please?

    PS - I have a generator at home that I use when the power goes off when I am at home.

    Want to use this as interim backup for when I am not at home.

    Thanks!

    Doubt if the batteries in there are OK. Maybe have them tested.

    Just get an inverter plus deep cycle battery. Say 105Ah. I run a pump for around 12 hours on this. All automated.
