How to Choose a Fish Finder Battery: Buying Guide
Now that you know some of the top fish finder battery brands in the market let’s discuss the factors you should focus on to ensure you make the right choice.
Here is a breakdown of the factors:
I) Battery Type
When looking for the best fish finders that can survive the unpredictable marine surroundings, there are two main types at your disposal. They are:
*Lithium Batteries (LiFePO4)
This type is highly rated mainly due to its lightweight and compact nature. As such, your device won’t be too bulky for comfort. In addition to that, this battery can discharge its power to its entirety without having an impact on its useful life.
However, these batteries tend to be the priciest in the market.
*Sealed Lead Acid Batteries
Also known as absorbed glass mat batteries, these units are fully sealed, making them the ultimate marine batteries. Their affordability and wide operating temperatures make these units to be very appealing to their users.
However, they have their downsides, including being bulky, making your device unnecessarily heavy. Further, discharging more than 80% of its power could damage its useful life.
The weight is a vital factor to think about since you wouldn’t want your fish finder to make your vessel too heavy for you to paddle with ease. So, consider going for lithium-ion units, the lightest and smallest batteries around, rarely exceeding 6lbs.
In addition to that, since kayaks don’t have too much space to accommodate huge batteries, smaller units would be a reasonable choice.
Next, it is vital for the battery to meet your fish finder’s power requirements. After all, there is nothing as frustrating as your device to dying down before you are done with your trip.
Assuming that your fish finder is powered by a 12V battery, it will consume around 1 amp per hour. Then, since your fishing trip is unlikely to exceed twelve hours, multiply this figure (time) by the device’s amps to know the capacity needed to power it.
With this simple calculation, you will know the kayak fish finder battery that will meet your fishing needs adequately.
IV) Charging Time
This factor mostly matters for an active angler since you wouldn’t want to waste valuable time waiting for your battery to attain full capacity. Here, lithium-ion batteries would be your best bet due to their fast recharge rate.
V) Watertight Storage
We all know the damage that occurs when electronics mix with water. So, you should do your best to ensure that you keep the battery in a waterproof case away from splashing water and other similar elements.
After finding the perfect box, store it in the vessel’s compartment, which is watertight, to maximize the distance from the water.
How to Hook to Trolling Motor Battery
If you want to get the best out of a trolling motor, you should connect it to batteries specially designed to power it. In most cases, a voltage of 12V, or 36V is enough to power it.
First, there are several things that should be close by:
*A wrench set
With these items in place, you can now get down to business. First, ensure that all power switches are off to ensure electrical shocks don’t occur.
For a 12V trolling motor, connect it to one 12V battery by fastening the black negative lead from the motor to the negative terminal. Secure the red positive lead from the trolling motor to the positive battery terminal.
It is important that you include a 50-amp circuit breaker in this connection.
And if it is a 36V motor you are dealing, with the process will be longer as you will be connecting three 12V batteries to the system.
You see, it isn’t as complicated as you may have expected.
FAQs on High-Quality Fish Finder Batteries
Let’s also answer some of the common queries regarding the top fish finder batteries to boost your knowledge on the topic.
Q: What battery size is recommended for fish finders?

Then, most of these devices draw between 0.25 and 1 amp per hour, with the screen size and brightness being the determinant factors on the amperage draw.
Q: How do I charge a fish finder battery?
A: It is pretty simple as you have to do is connect the charger to the fish finder via the charging port and then plug it into the socket. However, always ensure that the charger is compatible with the battery beforehand.
Getting the wrong charger could lead to catastrophic consequences.
Q: What are the benefits of lithium-ion batteries?
A: There are several advantages of using li-ion units to power your fishfinder. These batteries are small and lightweight, have a longer life cycle than SLA batteries, need less time to recharge and do not experience a drop-off in power when they start discharging.
