Good Morning,

I have a couple of quick questions about the Coral Box Backup Battery V2.

1. Will the V2 battery connect to a Varios 2 pump without any additional connectors (i.e. right out of the box)?
2. Can you give me a ballpark projection regarding expected battery runtimes (for a Varios 2)?
3. Is the battery lithium? If not, what type of battery is it?
4. Aside from charge cycles reducing the battery's ability to hold a charge, what's the expected approximate life for the battery?

Thanks

Hey Rick,

1: From looking at the photos, I would say yes. It has the same power supply type as the coral box dca pumps.

2: That's a DCA3,000 equivalent. So about 1.5 hours total.

3: Yes, it is lithium rechargeable.

4: The batteries can last for quite a few years. They won't be fully drained often and are trickle charged. The battery does not supply the pump with power when the AC power is on. So it's not using many duty cycles in regular use.

The V2 has been out about a year, I have yet to hear any reports of the V1 having diminished run time after years of use.

I appreciate the information.

One more question. If I connected the battery to a Tunze 6125, what do you think the estimated run time would be?

I take it I'd need to utilize Tunze's battery connector, right?

I apologize for the multiple posts. I run the Varios 2 at the lowest setting (i.e. 1 out of 5). Do you think I could get a couple more hours out of the battery (beyond 1.5 hours)?

Definitely. I tested my DCA2,000 at full power.

As for the tunze, I am unsure. As long as it has the same barrel jack plug size, it should work on any DC pump 12-24V

Awesome.

I'm unspeakably irritated with the non-lithium batteries I've owned which I purchased from one of your competitors (one of which failed very early into ownership), so I'm pleased to hear that your battery is lithium-based. I'll purchase one and give it a try.

Correction- they are sealed lead-acid rechargeable batteries. 2 x 12v, 2.2Ah cells for a total of 24v, 4.4 amp hours. I just received updated information from the factory on this.
