Minn Kota On-Board Digital Charger review

The Minn Kota On-Board Digital Charger

This MK 330D On-Board Digital Charger is one of the most popular on the market right now. It’s affordable for most people, while still offering the performance and reliability that you expect from your marine battery charger purchase. It’s perfectly able to protect your boat’s batteries and that’s something that every boat owner should be taking seriously.

Protects From Overcharging

This marine battery charger is able to monitor both the temperature and the voltage being output, allowing it to stabilize these things and ensure it doesn’t overcharge. This is what you need from a good-quality battery in order to keep it properly efficient at all times. In the end, it will help your batteries to last longer.

Shockproof and Waterproof

The chargers on this device are filled with epoxy, and it’s this that makes them completely able to withstand exposure to water and shocks. This is important when you’re on the water and there is some kind of wave impact or turbulence that might cause problems for lesser battery chargers.

Microprocessor Monitors Batteries

For the best results, you need a battery charger that’s able to tell exactly how much charge is needed at any particular time. THe MK 330D has a microprocessor built into it that monitors the batteries, ensuring the right amount of charge is delivered all the time. It’s an important safety measure too.

Temperature Compensation

If you are going to be using your boat in a location where the temperature is pretty high, it’s important to have a charger that can prevent your batteries from overheating. A temperature compensation system is the best way to do this, and it’s what’s offered by this battery charger. It takes the temperature in the environment and adapts accordingly.

The ProMariner 36 Amp 52036 Battery Charger Protournament

Fast charging matters to many fishers and anglers, so if you’re serious about fishing and you want to make sure that you’re always able to keep your boat moving at the speed you want to keep it moving at, this ProMariner battery charger could be what you’re looking for.

Distributed Charging

Another appealing feature of this charging device is the distributed charging method it employs. It essentially makes use of all the amps, meaning it can charge the battery faster because every possible component and element is being made use of and none of them are going to waste or standing idle.

Forced Induction Cooling Fan

Something else that increases charge speed is a lower overall temperature. If you allow your battery charger to overheat, it will take longer to charge the batteries. But this model uses a force induction cooling fan to keep the system cool at all times when it’s in use, so you won’t have to worry about overheating.

LED Light Display

A display that shows the system status allows you to stay on top of what your battery charger is doing and how much more it needs to charge before the charger can be disconnected. It can also detect and highlight any faults that you should be made aware of. It uses LEDs so is very bright and easy to use.
