Battery Settings
Battery parameter settings impact battery maintenance, battery lifespan, and UPS discharge
time. When you set battery parameters, note the following:
Battery string sharing is unavailable when Single/Parallel is set as Single.
Battery string sharing affects the actual charge current and the estimated discharge time.
An incorrect setting will cause a high or low charge current, which may damage the
batteries. An incorrect estimated discharge time may cause a data backup fault.
When you set parameters, ensure the following: Dis. cur. 0.1C EOD ≥ Dis. cur. 0.3C
EOD ≥ Dis. cur. 0.5C EOD ≥ Dis. cur. 1.0C EOD.
A cell consists of electrodes and electrolyte, which is the basic unit for the battery. Each
cell has a nominal voltage of 2 V. A battery is a module consisting of single or multiple
cells in a shell. Each battery has a nominal voltage of 2 V, 6 V, or 12 V.
