What To Consider When Buying A Battery Box?

Gladly, this guide will educate you through various matters in order to identify the best marine battery box that you will need to tour the seas in your precious boat. The first thing that you need to know are the very important factors to consider if you want to purchase a battery box.

To get started, just read the following below:

What is your current goal?

Do you wish to make your boat run at the best speeds? Are you going to purchase this so then you can have a spare battery box to use? Or are you going to do something experimental on your boat? Will you use it for deep cycling or for cranking?

These are just some of the questions that you should ask whenever you wish to purchase a marine battery box. But be sure to match your goals with the number of batteries that you have so then your purchase won’t be a regretful one.


The quality of the battery box will depend on the material being used. The typical materials that create a good type of battery box are polyethylene and polypropylene and are made with high densities of those materials. Polyethylene boxes are widely used by many due to its price, but can easily damage when the batteries heat up. What’s worse is that it may also absorb water.

Thus, it may not be a good option for long boat rides. On the other hand, polypropylene is extremely tough for withstanding heat as it’s a thermoplastic – making it perfect for long rides and heavy-duty boats.


If you already have a heavy boat, it’s not wise to go for the highest weight for the battery box despite its power because it doesn’t optimize the performance of your boat. Remember that you’re purchasing a battery box to ensure that right speed for your boat.

Take note that installing and carrying the battery is already a hard thing to do due to the product’s weight. That’s why you need to consider the weight of the product and the boat as a priority as well if you really want to have a faster ride. The weight of the box is also affected by its thickness, but note that thickness means protection as well. So be sure to balance those two out.


Aside from the weight, the size of the product matters a lot especially if you’re using a small boat. The boxes don’t usually have any size classification, as the dimensions of the product depend on the battery that can be used to operate it.

But note that using big boxes for smaller batteries is dangerous as it can damage the battery as you operate it due to the unnecessary extra space that may result in friction over the battery and the box.

Do You Want The Barebones? Or Extra Features?

There are two types of battery boxes that you can choose: the barebones or the ones with extra features. Based on the given factors above, it is better to purchase a barebones battery box if you need to get a product under a low budget, it is highly suggested that you get the barebones battery box models. Otherwise, if you need to pick one or most of the following features, you may need to spend more:

These are the extra features that you might want to get if you need a better and stronger model than before. Gladly, the price difference between a barebones and a battery box with extra features isn’t that high.

But tight budget means that you may need to buy a basic model first before you proceed with a better and more special type of battery box.

How About Box Vs Trays?

A battery tray is known to be smaller than a battery box as the product is flat, but is completely capable of storing your batteries well.

However, it may not be advisable to purchase these if you wish to bring the batteries because it might get wet along the way, especially if you’re using a small boat with small space to store the tray.

The tray may provide convenience though, as it’s low-cost and may provide you the basic feature of storing your battery tight as you can easily attach it there right away.

With this very simple guide, rest assured that you will never have any trouble getting the best marine battery box. Just remember that there are factors that you really need to observe when it comes to these items because it’s very hard to spend unnecessarily just because you weren’t able to protect your battery.
