BR1500MS2 UPS Load is showing 1% when I plugged to battery side 78W
I have the following electronics:
Verizon 5g Home Internet Modem - Which it says on it's socket connector it's 43W.
I also have two router switcher related devices that each it says:
5v 3A - so that would be 5*3 = 15W.
Also I'm connecting a USB A device so that's 5v * 1A = 5W.
Together it's 43+30+5 = 78W. I know it's less than the 10% of the BR1500MS2 UPS unit, but it should handle even a lower load I suppose.
But the issue is when I connect all these devices to the battery side, it shows on the UPS screen the load as 1% and the UPS Load at 13-15W and estimated runtime of 179 minutes.
When I tried to simulate a power outage by plugging out from the wall the UPS, the battery level went from 100% to 63% and UPS load remained at around 13-15W while estimated runtime increased to 239 minutes.
Could it be the devices I connected takes less than the W amount it says on them? Meaning those ratings are usually peak draw, not continuous so the UPS accurately measuring the UPS load and runtime expected for these devices? Can I rely on it?
