Battery Backup problem

[Bruce53]

My battery backup did not handle the load when there was a very brief power outage (30 seconds). In addition to the 8500H, I have a 85" qled tv, satellite system and ub9000. What is best type of battery backup that could handle this for at least 1 minute. I have and automatically switching generator that takes over the entire load after 30 seconds. In the past, before the 8500H, whenever the power went out, the battery backup stopped the equipment from resetting until the generator took over. In the instance above, the power was out only long enough for the generator to start, but it was not out long enough for the generator to take over.
Current battery backup is APC UPS ED 550.

To be clear, you say that in the past the UPS would keep the gear powered up until the generator kicked in? But now, it won't?

How long has the UPS been in service?

If it were me, I may look into replacing the battery before replacing the entire UPS. But, I have never looked into this, so it may be that the cost of a battery is very near that of a new unit anyway.

I guess it comes down to whether it seems like the battery has been in service so long it needs to be replaced, or if adding the AVR has put your load over the limit for that UPS. You should be able to look at the power ratings on your gear to see if you have exceeded the UPS capacity.

Thank you.
I did some searching last evening. I think that the load probably exceeds that of the backup. Likely need a larger one. Battery likely ok. did a reset on the backup and right now no farther alarms. Likely need larger VA capacity than 550

I recommend you getting Kill-A-Watt meter and see your actual power load. From there you could calculate how much capacity you need to sustain load for 30seconds.

Last year I bought the same UPS from same seller for $74

Used / Tested HP1500 G4 Hewlett Packard UPS 1500VA UPS | eBay

RS-232, USB. INTERFACE PROVIDED. maintenance free, sealed. Lead Acid Battery Features. at full load. 5 min at full load. 15 min at half load. LCD display.

These are rebranded Eaton units with Pure Sine output on the battery. (your current UPS is Approx to Sine, but APC has other models with Pure Sine)

What's the Difference Between Pure Sine Wave and Simulated Sine Wave?

Shopping for a UPS? Two types exist—and their respective output waveforms do have an effect on the equipment they're backing up.

Thank you. will obtain the meter and test it

I think you have your UPS set up incorrectly. I never put amplifiers, or AVRs on the battery load side of a UPS for either myself or my clients. What you want to do is put networking gear, Smart house controllers, and DVRs on the UPS side and the rest on the surge protector only receptacles.
