For a fish finder to work effectively, it has to use the right battery. However, there are several factors you should consider for an effective working fish finder. Today, I’ll be discussing the best fish finder battery. Below are some of the fish finder batteries and how effective they are when it comes to their use in fishing.

Lithium Batteries

These are the most recent fish finder batteries in the marine industries. They are light and small making it easy to carry and place them anywhere. They also provide perfect performance with voltages above 12v. Compared to SLA batteries, lithium batteries drain slowly in cold water. Their life span is longer compared to SLA batteries. These batteries have a built-in battery management system which protects and also balances cells regularly.

These batteries may be the best fish finder battery based on their advantages, however, these batteries are very expensive hence making them less affordable. They are also not fire-resistant hence can cause damage and injuries if not used safely.

It is rechargeable hence flexible enough to use when needed. The battery provides a 12-volt charge and able to charge more than one device at a time. Its high quality ensures a long life span and gives you the freedom to use it in any condition.

SLA Batteries

Being the most common battery in the fishing industry, SLA batteries are relatively cheap. They carry lots of power and can be charged fully overnight. Fast chargers may be used to charge them quicker, however, they shorten the battery’s life span. SLA batteries are also able to operate regardless of their position. They don’t leek and come in various shapes. However, these batteries have various limitations: 

  • They are heavy and large
  • They lose power drastically, especially during cold weather.
  • They are also short cycled.

One popular SLA battery includes:

SLA Battery Piranha MAX 160 Fish Finder

 It has a flush cover which keeps it free from acid.  Plate separators present in the battery helps prevent internal short circuits. It is made in the USA for West Marine.

Nickel Cadmium (NiCd) Battery

Another group of fish finder batteries is the Nickel Cadmium. They are generally lighter than SLA batteries but heavier compared to Nickel Metal Hydride or Lithium Batteries.

However, they are not environment-friendly and can cause memory effects as well as other issues. So these batteries are not recommended.

Best Fish Finder Battery: Conclusion

In conclusion, lithium batteries are the most advantageous. They can be used as excellent fish finder batteries with huge power output and small-sized. However, their cost is a great drawback. 

It is, therefore, best to choose a fish finder battery according to your preferences. These preferences may include required battery capacity, usage, dimensions and weight, cold-cranking amps, reserve capacity, the battery box you have, and also the battery’s charging speed. Batteries should be charged using their designed chargers to avoid damage and injuries and even explosions. Moreover, despite the type of fish finder battery you have, it greatly needs to be kept in a watertight compartment, low in the boat to improve stability.

From this guide, I hope you’ll be able to determine which is the best fish finder battery. If you have any questions, don’t hesitate to leave a comment below or contact me.
