Minn-Kota Chargers set automatically the load profile for each lead battery to recharge it and maintain it in perfect conditions of safety.
They can stay connected to the sector continuously, automatic monitoring of load according to the level reached by the battery. There is therefore no risk of overcharging.
Step 1: provide an amperage higher until you reach 75% of load (14.4 VDC).
Step 2: reduced the voltage at 13.5 VDC in order to limit the formation of gas.
Step 3: maintains the voltage between 13.2 and 13.5 VDC and amperage in 0.1 and 0.3.
