Best Pick: Best battery for kayak fish finder

Last updated on December 8, 2019 6:38 pm

When you’re off to kayak fishing, you will look for a battery that will last you the whole trip without a hiccup. Because you need to keep your kayak fish finder functional.

This wouldn’t be an issue if you need to stay powered in a fishing boat. All the equipment will draw only a few amps of power which can hardly make a difference in overall battery life. Besides, those heavy duty marine batteries are connected either with the solar panel, wind turbine or at least, to the main engine alternator.

Understanding the type of battery you require is more important. There are a variety of battery in the market, However, you should look for a battery that is portable, lightweight,

And of course, it has to deliver a useful amount of power throughout the whole fishing adventure. Battery with 12V SLA should be your best choice. Most of the depth finders in the market will require a ½ amp of battery in an hour. So, if you choose a 7-8 amp hour battery, that will nearly give your fish finder about 16 hours of continuous uptime. However, there are also some depth finder models which offer a lot of options and customizability with the exception of a few more amps per hour.

Preferred Battery Volume

Now, let’s discuss the necessary power that you require. I wouldn’t recommend you to grab a powerful battery for a less intense task. Because it may cause damage to the device which will drain the power. If not, it would be an inconvenience to carry the extra weight and recharge the battery frequently.

To detect the capacity by acquiring the fish finder’s current amps, then multiply the amps and desired operating time is given in Ampere-hours.

Most of the fish finders out there drain less than 1 amp of power when powered by a 12V battery. Smaller models draw even less power, but larger models with GPS  combo capability could drain a lot.

Since you will be using more likely a portable fish finder for your kayak, suppose it draws ½ amps at 12V. Fishing trips traditionally last for 8-12 hours, shorter ones even last less, 3-4 hours.

So, if you plan a long trip and want your fish finder to last too, pick a 15-18 AH capacity battery. For shorter trips, get 4.5-6 Ah. This capability is theoretical, so it’s better to get a portable yet powerful enough battery to meet your expectation.

Battery Types

There are several types of batteries on the market. Choose according to your convenience.

Sealed Lead Acid ( SLA )

These are mainly used for deep cycle or dual purpose marine batteries. They can function in any position and situation. Leak free and affordable, these batteries also offer variable sizes. Aside from its weight, this battery should be a hot pick.

Nickel Cadmium ( NiCD )

This particular type of battery has a couple of superior qualities. It is lighter than SLA and can give supreme current outputs. Despite all of these qualities, there’s a drawback. The battery is not at all environment-friendly. It also has a severe memory effect and other issues.

Nickel Metal Hydride ( NiMH ) or lithium battery

This sort of battery has nearly the similar capabilities as Nickel Cardium for much lower weight. In fact, it can be 3-4 times lighter than NiMH and 5-6 times lighter than SLA batteries. If you are not light in your pockets and don’t mind investing in a  special charger then go for lithium batteries.

Battery Power Box

If you are a frequent kayak fish hunter, then I would recommend that you keep the battery in a power center box. Then connect it to your small turbine or solar panel ( if you have any ) to keep those Fishfinders GPS working for long trips.

Store the box in the watertight compartment of the boat. The battery will be well protected from outside damage and interference as well as environmental forces.

Now that you have understood the different specifications of different batteries, let’s find out some of the best battery for kayak fish finder.

Charging fish finder batteries

It is a very sensitive and important task to charge the battery accordingly. Before plugging in the charger, be sure to check if its compatible with the battery. Because the wrong charger can damage the battery beyond repair. It also poses the risk of heat, fire, smoke and in the worst case scenario, an explosion!
