NXFAST Profile
This charging profile allows charging of NexSys 2V batteries at rates of 0.26 to 0.40 C
6
.
Opportunity Profile
This charging profile is used when opportunity charging is desired. It includes a start rate of up
to 25% of the battery’s 6-hour rated amp hour capacity and requires an equalize charge
performed once a week. The weekly equalize charge can be programmed to run automatically.
Operation
During opportunity charging the user should charge the battery during breaks, lunch or
any available time during the work day. The Opportunity Profile allows the battery to be
safely charged while it is kept in a partial state of charge between 20% and 80% of the
6-hour rated capacity during the work week. Sufficient time should be scheduled after
the weekly equalize charge to check and maintain electrolyte levels and allow the
battery to cool to ambient temperatures.
Daily Charge
When using the Opportunity Profile, the Daily Charge option can be set to add
additional charging time every day if the work schedule allows. This option should be
considered only when the daily work demand requires additional capacity.
VRLA Profile
This charging profile allows for Valve Regulated Lead Acid (VRLA) batteries to be charged. This
charging profile is an IEIE (constant current, constant voltage, constant current, constant
voltage) type.
Equalization Charging
Equalization charging, performed after normal charging, balances the electrolyte densities in the
battery’s cells.
Block Out Time
This function inhibits the charger from charging the battery during the block out time window. If
a charge cycle has started before the block out window it is inhibited during the block out window
and will automatically restart the charge cycle at the end of the block out window.
Refresh Charging
Refresh or maintenance charging enables the battery to be maintained at maximum charge all
of the time that it is connected to the charger.
