The difference is that in the case of stand-alone batteries, they are qualified without connection to ³the equipment in which they are meant to be used... .² Instead, they are connected to a generic load representative of in situ current draw, and a fixed potential charging source with fixed low output resistance.

What about a 28 Vdc battery that backs up the essential bus on an aircraft? What about a MANPACK battery that is discharged while being worn, and connected to a mains or generated-powered charger after the mission is over. In the commercial world, what about a battery designed to be used in an UPS? I have purchased several replacement batteries designed to replace the OEM battery in same.
