I got an email that I may be able to answer your question. I have the XS1500 Pro. A Google search for the model you mention shows that it's been discontinued. However, replacement batteries are available for both models. In my experience, manufacturers use standard battery sizes to keep production costs down. So, even if they don't offer the replacement themselves, it's available if you'll pull it and get the information. In your case, there's even a YouTube video detailing how to accomplish the replacement.

Question 2

How do you know if this external battery pack is working or not? There appears to be no lights on it and no indications on the back ups 1500 main unit?

Accepted Answer

So on the main unit, it will beep to let you know you have hooked it up and then remaining charge time will increase on the lcd readout. When i plugged mine in, it went from 45 min to just over 2 hours when I plugged in the battery pack. If it isnt working, you will notice the remaining time decreasing.

You can also use the software to see it working by the same method.

Question 3

How long can the External Battery Pack run at full load?

Accepted Answer

At full load (865W), the runtime can be extended to around 3 minutes.

Question 4

What is the expected battery life of the External Battery Pack for Back-UPS RS/XS 1500VA?

Accepted Answer

The expected battery life is between 4 to 6 years.

Question 5

How long does this extend your run time at full load if you have all four 9ah batteries installed in it?

Accepted Answer

Hi,

RS1500 has two batteries and the extender module has four of the same batteries, so you should see a 2X (or so) increase in run time,
