substation battery system 120 voltage
(OP)
Hi,
For 120V dc battery, most of the times we use 125V or 130V.
Theoratically, we consider 2V/cell. So for 60Cell, it will be 120V.
What is the reason to populate the term 125 or 130V? Which one is correct?

But which term is correct for communication and documentation purpose when refer " Battery "? 125 or 130?

DPC, you are correct in saying that many a times we may have lower no., of cells. Some UPS manufacturer's routinely give 54 cells, since the DC link voltage is limited by the lowest voltage that the inverter can tolerate, and also the current carrying ability of the components, since to deliver the same kVA o/p at lower DC voltage, a greater current is seen at the DC link level.
