The 5 Best Battery for Kayak Fish Finder Reviews in 2021

Fishing on the Kayak boat is a traditional method for fishing lovers. 2 or 3 people can sit on the boat and move around the river and lake for fishing. A fish finder helps to find fish quickly that saves time, and makes it effective. The kayak boat has no extra battery to power up the fish finder, so you should take a battery to use a fish finder. 

All batteries are not suitable for fish finder because you have to follow some parameters discussed in this article. We have tested many batteries and picked 5 best battery for kayak fish finder with adequate capacity, life cycles, DOD, and all-weather working support. Let’s see the batteries for the fish finder.

What Battery To Use For Fishfinder?

There are two types of battery recommended for fish finder in the kayak: lithium and SLA batteries. Lithium-ion batteries have a higher energy density. They save a much bigger capacity per unit of weight and volume. Its linear discharge option provides the amount of the stored charges accurately. But, it does not work at low temperatures and reduces their life by up to 25 percent. Sealed lead-acid (SLA) batteries are currently the cheapest batteries for self-consumption systems. They are the longest-running and modern types of batteries. These batteries’ lives are between 3 and 4 years when they are subjected to many discharge cycles or when they are forced and work below 80% continuously.

On the contrary, if we do not force the cycles and keep them above 80% and only drop below this value occasionally, they can reach 6-7 years. Both batteries need fewer maintenance costs and can be used anywhere for their lightweight and compact design. Our recommendation is to use Sealed Lead-Acid batteries for fish finders, and it is better and reliable than Lithium batteries.

How To Choose The Battery For Fish Finder?

Before choosing a kayak fish finder battery, you have to follow some factors. If anyone from the list is missing out, you will not get the right battery for your fishfinder. Let’s see the factors below:

Type of battery

You can use Lithium and SLA batteries for a fish finder. Lithium is costly, so everyone cannot afford it. In that case, the SLA battery is cheaper than the Lithium battery. Both batteries provide maintenance-free service and longtime service. They are lightweight and small, so you can install them anywhere you want. Now, you can choose the battery according to your needs.

Protection

Fishfinder batteries must-have safety protection. The short circuit, over-voltage, over-current, and more accidents often occurred when you left the batteries in charging. The batteries with AGM technology automatically prevent accidents by stopping the battery’s power supply after a full charge. So, there is no chance of accidents. The AGM batteries provide spill-proof protection and shut down at low power mode. So, you should consider the protection issues while buying a battery for a fish finder.

Capacity

For fish finders, you need a 7 to 10 AH battery for long time usage. This range of batteries is small and compact. You can go for large size batteries, but they need enough space to install. So, decide what you need, and the smaller batteries are enough for a fish finder.

Time of charging

The time of charging of the fish finder battery is one of the main parameters that should be taken. The battery must be charged up within 4 to 6 hours. Because the fisherman goes hunting fish daily so if a battery takes more than 6 hrs to charge up 100%, it will not be preferable.

Size and weight

The size of a fish finder should be small and compact. Heavyweight batteries are difficult to place in the kayak boat. Also, a lightweight battery is easy to carry and comes with a carrying case that protects the battery from water and shock. Its weight should be no more than 5 pounds.

By following these factors, you can easily choose a perfect battery for a fish finder.
