According to the specs on the Minn Kota charger it is a charger for bulk (to recharge the battery) and maintenance (to keep battery at full charge). I charge my trolling batterys with a onboard charger @ 5 amps per battery then when fully charged the charger maintains the charge until I unplug it. Read your directions carefully and they should explain the best way to use the charger. Only using 2 amps would never get a trolling battery back to full charge for about 2 days.
