Of course. The shortcoming being that running the UPS down that far would take a few hours - at which point I start thinking asking around might be more efficient use of time, just in case somebody knows, since really proving the pudding might take multiple cycles of full discharge-recharge, plus it's production equipment hanging on it I don't want to keep shutting down. > The documentation does cover this.

Thanks. I was assuming the fullest docs were also on the Website; guess not. To another reply - it's the "cyberpower" driver that works with the 1500AVR. (The more modern driver skews the values badly. I requested the right conversions from the manufacturer, but the rep who responded regretted that he couldn't get the tech staff to reveal those.) Am I right that on average, presuming a professional-level UPS (this sucker at least is a rack-mount with a few hours of battery in it), and with PCs with bioses which will can be set to boot on any fresh power application, that I'm better off without sending "shutdown" to the UPS?
