Fish Finder Battery Fundamentals

What kinds of batteries that we can use for the Fish finder? And what is the spec of the fish finder battery? And what is the inner structure of the fish finder battery? This chapter will take you to learn more.

Battery Type

Lithium Battery

LiFePO4 batteries are popular in the market due to their extremely long cycle life and high safety. In addition, because the raw materials do not contain precious metal elements, the price is relatively cheap. The cycle life can reach 2000~4000 times.

Lead Acid Battery

Lead-acid batteries have gone through decades of market research. However, it is also because the lead-acid technology has been developed to the end that its energy density is low and its lifespan is poor. Therefore, if lead-acid batteries are used, they may need to face the problem of multiple charging and short single mileage. But a very advantageous point is that the price of lead-acid batteries is lower than that of lithium batteries.

Why Choice Lithium Batteries For My Fish Finder?

Light Weight(50% Weight)

Lithium-ion marine batteries are extremely lightweight; in fact, most weigh only 50% the mass of their lead-acid counterparts. These batteries are easy to get to and from your boat, and you can even use them in your kayak to power your trolling boat, in addition to your fish finder.

Dependable(Safe)

Lithium batteries are safe and reliable. To illustrate this fact, let’s compare them to lead-acid batteries, which should not discharge more than 50% of the battery’s capacity. Doing so will damage the battery, and after a few times like this, your battery will be completely dead.

However, when you use a lithium battery for your fishfinder, it can be discharged to 20% of its capacity without damage. Most Li-Ion batteries have a failsafe switch that registers the battery as dead once it reaches 20% capacity, so you don’t have to risk damaging it. So in a sense, you can drain it to 100% without worrying about it.

Fast Charging (1-2hours)

Lithium-ion batteries can be charged four times faster than lead-acid batteries at the same charging current. This is because lithium batteries accept charging better. They have low internal resistance and charge at higher currents. Because they have low internal resistance and charge at higher currents, they are able to accept all the energy during a charge cycle, effectively charging much faster than lead-acid batteries.

How To Prolong The Life Of Your Fish Finder Battery

As we all know, Proper maintenance of the battery, and compliance with the principles of battery use, which can greatly extend the life of the battery.

Improper use of the battery will also shorten the life of the battery.

Damage to the battery structure.
