I am trying to find information on what the technical data should be on batteries for the above unit.
I replaced all of the batteries but the red LED remains on. I also notice that the Battery voltage has not changed and am trying to find out what it should be.

Last Battery Transfer: Unacceptable utility voltage rate of change
Internal Temperature: 90.3°F
Runtime Remaining: 15 minutes

Power
Input Voltage: 236.1 VAC

Bypass Input Voltage:
Output Voltage: 207.0 VAC
Current:
Input Frequency: 60.01 Hz

Load
Load Power: 52.0 %Watts
Apparent Load Power: 43.0 %VA
Load Current: 20.79 Amps

Battery
Capacity: 100.0 %
Battery Voltage: 216.0 VDC
External Batteries: 1

There are 4 battery packs in the unit. What voltage should I be seeing? It was around the same before I replaced the batteries.

Thanks.

What I was looking for was more technical information on the unit and that seems hard to find.
For example, does it only need two battery packs to actually function? That would only be 200VDC.
And does it use 4 packs so that it can extend it's time?

With another UPS I had previously, I had built a complete external battery setup. In that case, it was 20 marine batteries, using external intelligent charger and connected to the UPS via breaker. If I can't trust the UPS, I know I could trust my own external batteries but I've seen suggestions against using it because the unit would not be able to calibrate etc. That would not matter much to me, so long as I knew my batteries were working well, I only need a few minutes of backup power for the geny to kick in.

So after a couple of days now, the voltage has gone back to 216VDC for Batteries. There is 15 minutes of run time.
If anything, I suppose I should be able to get some sort of warning that it won't be able to handle it when I shut the power off?
I need at least 30 seconds for the geny to kick in then the UPS needs to last long enough to sense power and come back off of the batteries.

Just trying to figure out how to test this without taking the load down as it's a ton of work to get everything back up.

Anyone?
Also, I don't suppose there is any way of testing to see if the batteries will hold the load without actually putting the load on the batteries? I mean, there is no internal sensing that would let me know this without accidentally taking the load down if the batteries won't hold?

I don't know the answer to your other questions, but yes, the only way for a SmartUPS to test the battery is to put the load on them. Batteries can appear normal until you try drawing significant current out of them.

Ok, just wanted to confirm. Guess we'll give it a shot tonight.

I did it from remote, I read that doing a calibration didn't put the unit on batteries. You mean it did? If that's the case, nothing went down.

Didn't last very long on the batteries so guess I need new ones, again.
Worse is that while the batteries discharged very quickly, it did last long enough for the geny to kick in.
Also, when I turned the utility back on and it switched back to utility, it dropped part of the load, but not all of it.

I then switched out two of the packs which aren't known to be brand new batteries such as the gruber and like the other test, was able to pass a recalibration test but am not sure if it'll pass a load test. Guess there's only one way to find out again.

I really wish I could simply use externals, these little batteries are ridiculous.

I see in an above post you ran a calibration - how long did it stay on battery?
That should be the amount of run time you can expect if an outage occurs.

I didn't know that a calibration meant that the UPS tests how long it can stay on it's batteries. It was maybe two minutes at most.

How long have these batteries been in use? Months? Years?

At this point, I've mixed them up so am not sure. I did a load test on every battery in two packs this morning and all of them were in the 'Weak' state. The two packs which are not the new Gruber batteries were supposed to be new but I suspect they are not at this point. Looks like I should get 16 new batteries.
