The Minn Kota On-Board Battery Charger is a powerful electrical device designed for charging and maintaining 12-volt 6-cell lead-acid batteries. It is suitable for use with FLOODED/WET CELL, MAINTENANCE FREE, and AGM/STARVED ELECTROLYTE batteries. The charger is not intended for use with dry-cell batteries or for supplying power to low voltage electrical systems other than for charging and maintaining batteries.
The Minn Kota battery charger provides a fully automatic charging process with multiple banks, allowing for independent charging of multiple batteries or combinations of batteries hooked in series or parallel without disconnecting them from any switches or wires/straps. Each output cord is equipped with a temperature sensor that adjusts the charging profile to ensure full charge without overcharging or undercharging, optimizing battery life. The charger is designed with short circuit/reverse polarity protection, ignition protection, and watertight construction for enhanced safety and durability.
The manual covers several models with varying specifications:
All models utilize an 18AWG input cable and 16AWG output cables. The output cords are 6 feet long, with the exception of the 'S' models which have an 8.5' input cable. The maximum extension length for DC battery leads is 15 feet, using a minimum of 12 AWG wire.
