Five Tips for Buying Marine Battery Chargers

If you want to make sure your boat always has power, then you should buy a battery charger for your boat. There are a few things you need to consider when buying marine battery chargers. Some of these things include power, installation, and type. This article will...

Power

One of the first things you need to consider when buying marine battery chargers is power. More powerful designs will fully charge your batteries faster. Cheaper marine battery chargers provide 5 amps per bank which can take a full day to charge your battery. You may want to invest in a more powerful charger that provides 10 amps per bank.

Installation

One of the next things you should consider when buying marine battery chargers is installation. You should make sure to choose a model that comes with all of the necessary equipment to install the charger. Some marine battery chargers also come pre-wired with all of the fuses and cables. However, pre-wired designs can be more difficult to repair.

Type

You will also need to think about the type of charger to buy. Two types of marine battery chargers include smart and trickle designs. When power in your batteries gets too low, smart chargers will start charging them automatically. Trickle marine battery chargers require manually startup, but include timers that will stop charging automatically. This will help prevent overcharging the battery.

Capacity

One of the next things you need to think about when buying marine battery chargers is their capacity. This will determine how many batteries can be charged at one time. If you have more than one battery on your boat, then you should look to buy marine battery chargers that can charge up to three batteries at one time.

Water

One of the final things to consider when buying marine battery chargers is water. Since you're using the device on a boat, you will obviously be around a lot of water. Therefore, you should look to buy marine battery chargers that are completely waterproof. They should be sealed on all sides. The design should also use circuitry that is resistant to moisture.

These are a few tips for buying marine battery chargers. If you use multiple batteries on your boat, then you need to find a design that can charge multiple batteries at once. Also, make sure that you only buy marine battery chargers that are completely waterproof.
