Battery Time Remaining

The SC200 or SC100 obtains characterization data from either periodic battery discharges
(SC100) or every full battery discharge (SC200) (to the specified end voltage).
During a battery discharge, the SC200 or SC100 uses this characterization data to calculate an
estimated time until the battery will reach a specified end voltage.
If a battery disconnect LVD is fitted then the end voltage will usually be the voltage at which the
LVD disconnects the battery.
Battery Time Remaining is designed for a constant power load. The accuracy of the time
remaining calculation will be reduced if the dc power system is connected to a predominantly
resistive (constant current) load.
For details refer to Battery Time Remaining in the SC200 or SC100 System Controller Operation
Handbook (see Related Information on page i).
