How would I auto turn on my 12v battery bubbler when power goes out?

Fwdmotion · Jun 30, 2018

I am wiring up my ecotech's to this battery but I am wondering I have one of those 12v bubblers as well.. Is it possible to have this auto turn on when the power goes out?

The battery is being drip charged by a charger so maybe something that would tell it when the charger loses power to turn on device? I am not sure what I would be searching for, any help is appreciated

That UPS should turn on the second the power goes off..
Quite the experiment you have going on there! ;Wideyed

Ya I figured we live in a storm area here in Florida.. Might as well prepare for multiple scenarios now

The 12V Battery is not hooked up to the UPS system that is seperate. The battery is meant for a few ecotech's and the 12v bubbler, but not sure how to get the 12v bubbler to turn on when power goes out (trickle charger loses power would be the signal for this)

You can go to walmart and buy a computer UPS, they work perfectly for this... This way you can ditch the battery altogether...
Where in Florida?

Hmm not sure how that would work - I don't want the backup bubbler to be on unless there was a power outage

Palm Beach Gardens area here, not crazy far from your area

Try using a standard automotive 12v relay and a old plug in power supply(12v output) from an electronic device. If you use a 5 pin relay you can wire it as normally open, cutting battery power, until the 12v from the power pack shuts off with power failure. Then it will close, completing your battery pack feed to the bubbler. Schematics are online.

If you want something simple and inexpensive, I use these on some of my tanks. They plug in to keep a relay open and have two D cell batteries inside. Power goes off, relay closes and the pump comes on. Supposedly runs for 6 - 8 hours, depending on how fresh the batteries are. I have never had them run long enough to exhaust the batteries before the power came back on.
