Heat and moisture can destroy a battery charger. That's why Minn Kota's chargers are enclosed in aluminum extrusions with cooling fins, to efficiently dissipate heat from inside. This protects sensitive electronics against damage from overheating. And, our chargers are completely sealed with waterproof gaskets. That means no moisture, and no potting compound to trap heat inside the charger. To verify the safety and performance of our chargers, we had the experts at Underwriter's Laboratories test them. Minn Kota is the only full-line manufacturer of waterproof on-board chargers that bear the UL logo.
