Hello, I have 2 APCs, a Back UPS Pro 900 and a Backups BX 1400U. I bought the 1400U in 2018 for my network cabinet thinking it would have a much higher capacity than they Pro 900 but I noticed the 1400U was reporting that a load of 120W would only be 440 seconds of up time. When I put 120W on my Pro 900 its says ~40 minutes. I assumed there was something something wrong with the battery so I ordered a new battery from APC. I just installed the new battery and now, with 100% charge, the reported uptime is still only 10 min @ 120W according to Powerchute. Why is that? Is my 1400U a dud or is there something I am missing?
The website says it should be 45m
