The only new thing I’ve seen is I think there are some UPS models now using Li-ion batteries, but still like Colin says, almost no UPS is designed for long runtime without external battery packs. Even buying a higher power unit and running it at a fraction of rated load doesn’t help much because they are inefficient at low load.
I forget who was selling the Li-ion units.

From: Colin Stanners Sent: Sunday, March 29, 2020 9:48 AM To: AnimalFarm Microwave Users Group Subject: Re: [AFMUG] Good Home UPS Most consumer UPSes only come with enough battery to power their full load for 5-10min so to power a 250W-using desktop and monitor for 30min I think that you'd need the amount of batteries (2x 12V 12AH) usually seen in 1000-1500VA UPS models. There's not much "better" with non-network UPSes as the service provided and reliability has not changed noticeably in over 20 years.

It runs everything in my home office, plus the waterheater/furnace (heat only). It's on a transfer switch to plug the portable generator into it for an extended outage. Luckily I'm on all underground utilities, knock on wood, have had 1 power outage in the 15 years we've lived here.

It matters if you are running electronics or a sump pump, and if you just want enough time to save your work or if you want to keep working for a couple hours. Also most people have battery operated laptops and tablets now which changes the UPS strategy. Another factor is if it’s in a location where fan noise would be bothersome. I’ve had good luck with Tripp Lite SU750XL, it is dual conversion, replaceable battery, and Powerpole connector for external extended runtime battery. But the fan runs all the time and it would probably drive you crazy in a bedroom or home office. And if your electronics aren’t fussy about the quality of the input power, dual conversion is probably an expensive overkill.

Older models had replaceable batteries and will often work fine with a new battery; they don't have a calibration command so it's good to put a light load (30-50%) and let them run down to empty once or twice so that they recalibrate themselves to the new battery. Some new Back-UPS models don't have the replaceable batteries.
