Minn Kota On-Board Digital Charger Product Review

Minn Kota chargers are designed to deliver the right amount of power every time you plug in, no more and no less. This On-Board Digital Charger is controlled to monitor temperatures and level of battery-life to create a faster, regulated and precise charge. Also – This Minn Kota delivers up to two times faster charge times in high heat conditions.

The multi-stage charging ensures a full charge while at the same time preventing overcharging. This technology automatically controls current and voltage over the three charging stages; bulk, absorption, and maintenance.

This charger recovers the batteries quickly after a full day on the water and keeps them conditioned during prolonged periods of storage. However, it’s important to keep in mind that this charger is large and heavier than most three bank unity on the market. Make sure that you have enough clearance to mount it where you need it.

Like most types of marine battery chargers, it features enhanced status codes to display charge stage, maintenance mode status, error notifications, and full charge. Unlike most marine chargers, the Minn Kota has an automatic shut-off feature that extends battery life by shutting down when charging is complete.

This battery has a 10-amp capability that’s split into 5 amps per bank. Plus, this charger is corrosion resistant and is designed for use in saltwater.
