Smart-UPS RT 5000 RM XL - New Battery addition - configuration

[Andy_K]

Hello, we have a UPS 5000 RM XL unit, where we changed the first two battery banks and runtime with our equipment is about 1 hour at 10% load.  ( i assume thats about 300watts) 

We have an external expantion pack with 4 battery slots:

We put in two slide-in banks of

Yes, the other half of the SURT192 is with unplugged old batteries that we removed, but i think that is OK? Or can this overload the 2 out of 4 batteries? Now when we do a runtime test it doubles up to 2h15mins which is what we need.

Extra info: With a multimeter I see behind the bLue cable that goes to the UPS feeds the Left side batteries, and the bRown cable feeds the Right side batteries.  🙂

Now my question:  in the web management page UPS / general it asks how many external batteries and Batt Capacity in Amp Hours?  this seems to help the UPS estimate how long it will last?

I think one pair of these RBC140(two slide-in banks)  represents 1 ?  and it is 5 Ah ? 

Or if we fill the SURT192 completely that would be 1 or 2 batteries and 5 or 10 Ah?

Thanks!
