On a Netgear ReadyNAS (ours is a 2100, running RAIDiator 4.2.17) there is a setting under UPS Configuration that allows you to select the "low battery threshold".  It has options of 10%-90% in 10% increments, as well as Auto.  Does 10% mean the battery is 10% drained, or that it has 10% left (90% drained)?  The documentation just mentions that it can be adjusted; but I can't find anything that clarifies this rather ambiguous setting.

It means that the battery is either 90% drained, or can't hold more than 10% of the charge.  If the UPS batteries are more than a few years old .. replace them.  They're worthless if they only hold 10% of a charge.

Ummm... I don't think you understood the question.  I'm not asking about the UPS itself, but rather the setting on the NAS device which tells it when to shutdown based on the battery status of the UPS.  I'm just not sure if 10% (for example) means 10% gone (90% left) or 90% gone (10% left).

The level is "battery remaining reserve".

100% means the battery is full.
10% means the battery is 90% gone, 10% remaining.
0% means the battery is depleted.
