Multi-Stage Charging Overview
When the ProSport charger is turned on, the green AC power indicator will turn on followed by the red
charging LED indicator.
The multi-stage charger will provide the following:
ProSport Charging
During this mode the ProSport will use ist available charging amps (as controlled by temperature) until the
battery voltage is raised to 14.6V DC (lead-acid factory setting).
ProSport Conditioning
The ProSport will hold batteries at 14.6V DC (factory set for lead-acid batteries) to complete charging while
conditioning batteries by desulfating each battery connected. Upon completion the ProSport will go into float
mode.
3. Float / Maintenance Mode
During this mode the red “Charging” LED will turn off, indicating that the charging process is over and that the
charger is now maintaining your batteries on-board. Only the green LED will remain on, indicating “Power On /
Float-Maintenance Mode”.
This is a precision 13.3 volts (lead-acid factory setting) finishing voltage that maintains each battery, perfect
for short or long storage periods and never overcharging your batteries (step down voltage regulation mode).
Note: The only LED indicator that will we on during the float mode will be the green “Power On” LED indicator.
