Voltage to maintain Battery Charging.
Float voltage = Number of battery cells x battery float voltage per cell.
Typical battery float voltage per cell (ask the battery manufacturer for
confirmation):
Valve Regulated Lead Acid Battery (VRLA):
2.27Vdc for cell
240 cells x 2.27Vdc = 545Vdc
NiCd Battery without boost-charge:
1.41Vdc for cell
284÷309 cells x 1.41Vdc = 401 ÷ 436Vdc
NiCd Battery with boost-charge:
1.41 (1.55 boost-charge) Vdc for cell
281 cells x 1.41Vdc = 397 (436) Vdc
Flooded Lead Acid Battery without boost-charge:
2.23Vdc for cell
180÷195 cells x 2.23Vdc = 402 ÷ 435Vdc
Flooded Lead Acid Battery with boost-charge:
2.23 (2.35 boost-charge) Vdc for cell
180÷185 cells x 2.23Vdc = 402 (423) ÷ 413 (435) Vdc
Maximum Battery Recharge Current.
Max 20% of battery capacity (Ah).
Example: 100Ah – max. recharging current 20A.
Residual Battery Autonomy time before UPS forced shut-down.
Standard set 3 minutes.
Settable from 1 minute to autonomy time in minutes.
Number of cells of the Battery, see "Float voltage".
Example: 240 battery cells
