Estimated 6101 Backup Time with Safety Connector + 12 Volt 55 Ah Battery?

[JER-Z]

I am looking to buy a battery/charger to hook up to a safety connector for my 6101.

How much backup time, could I expect with one 6101 running on this battery?

12 Volt 55 Ah Sealed Lead Acid Battery

It depends on what speed you are running the pump at. The pump will still follow the pattern of the controller, but at 50%. If you are running a 30% - 100% pulse, it will run 15% - 50% pulse on battery.

ok so let's say worst case estimate, where the pump runs constantly @ 100% AC, 50% DC.

Also sjm, I am glad you replied. Do you think the battery i linked will be good for this purpose? I think it is pretty much a slightly bigger version of what you are using? I did a search and found the one you use, and went for a slightly bigger aH rating. Will the terminals on this battery be ok?

Thanks

Not sure if these numbers are correct, but if my math is right....
6101 = 44W/hr @ 100% (24V)
22W @ 50% (12V)
22W/12VDC = 1.83 amp
55ah/1.83a = 30.5 hr

The controller is also powered which uses some. Add in losses and such and I would say roughly 24 hr run time.

sounds good thanks...

So this battery will work well w/ the safety connector? The terminals ok?

 

[sjm817]

Yes. Terminals are fine. You can get what you need to connect things up at a hardware store. You also need a float charger.

At 12V the 6101 uses only 12W about so it should last almost 55 hours.

Thanks for the clarification on the power use. That makes things simple. 1 hr run time per ah.

wow even better! thanks for the help guys

Use something to cover up the positive terminal of the battery to guard against an accidental short when working around the battery.

 

[JER-Z]

ok will do, any suggestions?

 

[sjm817]

Piece of rubber hose or whatever. The connectors on that battery are kind of funky....

 

[JER-Z]

ok cool. i ordered the battery and the float charger you use.

Thanks

Good luck with it!
