Nothing can be the biggest obstacle on your fun and thrilling sailing trip than a poorly charged or dead marine battery. Hence, it is extremely crucial to select the right marine battery charger for your boat. With the high-quality deep cycle marine battery charger at your disposal, you can be sure that you and your family will have a safe and enjoyable time on the water.

However, instead of directly buying marine battery chargers, it is important to consider a few things to make sure your charger is not a waste of money.

Here are things to consider before buying a marine battery charger -

  1. Battery Type-

The first thing you should consider while buying marine battery chargers is the type of battery you need to charge. The most common marine batteries are — marine stating batteries, marine deep cycle battery and marine dual-purpose batteries. These batteries are further sub-categorized into wet cell batteries, gel cell batteries, AGM. Look for the below-mentioned three traits while purchasing a charger for your marine battery -

  • Input voltage — 120 or 230 VAC
  • Battery type — Gel, Flooded or AGM
  • Battery capacity — Mentioned on the battery as “Ah”.

2. Size-

The size of your battery is also a crucial thing to consider while purchasing deep cycle marine battery chargers or other marine battery chargers. But, here doesn’t mean the physical size of the battery, but with the size we here mean AMPs. You need to understand how many AMP hours does your battery store. Your chargers power depends on how fast you want to charge your battery. If you want to charge your battery quickly, you need a charger with high Ampere power.

Getting the right size charger is also imperative to make sure that it supplies your boat with the needed amount of power and doesn’t waste energy. The frequency of using the boat plays an important role here. A boat that is on the water on a daily basis needs a larger charger than the one that is docked for most of the week. Finally, you will want to consider any other items on the boat that consume battery such as refrigeration systems, dashboards and lights.

Moreover, if you are going to be offshore for long periods of time, then you need a charger that can charge your battery quickly.

3.Environment-

Before buying a charger, it is also important to understand the environment of your boat. Is your boat exposed to harsh elements such as freezing temperatures, humid conditions, consistent rain and more? Why this is important to know is because some chargers and inverters are suited for humid conditions, while others might be suitable for freezing temperatures.
