Do I have to break my BX1500G in? It's worse than my 4 year old BX1200!!

So I picked up a BX1500G a few months ago, tested fine but my 4 year old BX1200 is still running great so I took my time switching them out. I figured I wanted to see if my BX1200 was played out and in need of new batteries so I hooked up my two routers and two cable modems to it and unplugged it. Ran out after 3+ hours. Wanting to see how long my brand new 1500G would run, same setup, and it went for 2.5 hours? I did notice the LED showed about 3 hours of run time with no load after it was charged. Now its charged again and shows over 4 hours (262 minutes). So I'm wondering if I have an issue or do I just need to cycle it a few times? I think these are lead acid so I wouldn't think so.

APC makes good UPSs, excellent warrenty, but they output a lot of incorrect information.
So, don't trust what your UPS says, since you can't.

My issue is, my 4 year old APC BX1200 which I think is 1200VA/780W has a longer run time under the same load than my brand new BX1500G which I believe is 1500VA/865W. Is there there something I'm missing here, shouldn't the new one with more watts be lasting much more than the older one under the same load? Maybe I just don't understand what the numbers really mean?

I only brought up the time remaining increasing as part of my conjecture that maybe I need to break this in to get a good run time. I never trust the time given either.

I guess I need to be more scientific but I think I do have an issue.

here are the run charts for each (scroll down)...

1500G
[https://www.apcc.com/products/resource/include/techspec_index.cfm?base_sku=BX1500G]

1200
[http://www.apc.com/resource/include/techspec_index.cfm?base_sku=BX1200]

1500G @ 400W load should run 17.4 minutes, 1200 is 11.3. Under the same load the 4 year old 1200 is performing better.

Any thoughts on how to present as an issue to support?

Appreciate the info. I actually did charge it up for 24hrs with no load. Going to try one more time with a fan or something that has a pretty well defined load on both UPSs tonight. I'm actually pleased the 1200 is getting 3+ hours with the modems and routers. That will keep the laptops happy for a while.

Hmmm - I wonder if it was an issue with plugging it in for 24hrs, I could have sworn I did. This time I made sure it was in for 30+ hours, ran my old 1200 with a lamp and a 100W bulp (a killawatt device confirmed it was 100W draw). The 4 year old BX1200 ran for 45 mins or so which is impressive considering it is 4 years old and the runtime rating for the BX1200 at 100W shows 54 minutes. Same test for the 1500G and it appears to have run for 85 minutes or so which is in line with the chart showing 81 minutes Ibeieve. Going to charge both up again and go back to my original test of two routers and two modems after getting a killawatt rating off that as well. But I'd say it appears to be much better now.

Thanx.
