The Minn Kota MK-460PC will not only charge your batteries but condition them as well. It also has a temp sensor built in so if your boat is in the garage in the summer and it gets above a certain degree, the charger will cut-off and or will not kick back on when the batteries drop thus keeping the charger from boiling the batteries. The Minn Kota chargers will also charge other type batteries such as AGM, Gel, or Flooded.
It's all coming together and we have you covered @ Shut-Up-And-Fish LLC
