Stage 1 - Analyze & System Check: The ProSportHD Mode LED will pulse blue, indicating it is analyzing all battery connections and ensuring each battery is capable of being charged. When completed successfully, the “System Check OK” indicator will illuminate green. This takes approximately 1 minute.
Stage 2 - Charge: The ProSportHD Mode LED will be solid red and the ProSportHD will use all of its available charging amps (as controlled by temperature) until the battery voltage is raised to the selected absorption voltage.
Stage 3 - Condition: The ProSportHD Mode LED will be solid amber. During this mode, batteries will be held at the selected absorption voltage to complete charging while conditioning each battery connected for up to 3 hours as needed.
Stage 4 - Auto Maintain: During this stage, the Mode indicator will be solid green, indicating it is monitoring and auto maintaining your batteries as needed to maintain a full state of charge. At this time, the blue Power LED, green System OK and green Mode LEDs will remain on, letting you know your batteries are ready when you are.
Stage 5 - Storage: During this stage, the ProSportHD will enter into it's once a month Storage Recondition mode. The green Mode LED will pulse, indicating that while your batteries / boat are in storage, the ProSportHD is reconditioning all batteries for up to 3 hours once a month to extend battery life and provide maximum reserve power performance on the water.
For use with Group Size 24, 27, 29/31 Flooded Lead-Acid, VRLA AGM and LiFePO4 (approved) batteries. Not for use with large capacity (4D, 8D) batteries.
