AC Power and Charging LED Status Indicators

The ProSport includes two LED indicators as shown below.

Green “AC Power” LED indicator:

When on, the green LED indicates that AC power is present.

Red “Charging” LED indicator

When on, the red LED indicates that the batteries are in the multi-stage charging mode. When charging is complete, only the green “AC Power” LED will remain on.

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.
