best kayak fish finder battery [Answered]


As an avid paddler, having quality equipment is imperative for a successful fishing day. A kayak fish finder battery is a crucial piece of equipment, especially for those who want to locate fish quickly and efficiently. Choosing the right fish finder battery can be overwhelming with the multiple options available in the market. This article aims to help kayak anglers in selecting the best kayak fish finder battery for their needs. We will provide an overview of the different types of batteries, key factors to consider when choosing, and outline the top recommended batteries. Proper maintenance of the batteries and alternative options will also be covered to extend their life and ensure uninterrupted water adventures.

II. Types of kayak fish finder batteries

There are three common types of kayak fish finder batteries: lithium-ion, sealed lead-acid, and nickel-metal hydride.

  • Lithium-ion batteries: These are lightweight and compact, making them an excellent option for kayakers who want to minimize the weight of their gear. Lithium-ion batteries have a longer lifespan and maintain consistent power levels, but they can be more expensive than other options.
  • Sealed lead-acid batteries: These batteries are economical and offer a good balance of power and weight, making them a popular choice for kayak anglers. However, they can be heavier and larger than other options, which may not be ideal for those with limited storage or weight capacity.
  • Nickel-metal hydride batteries: These batteries offer a good balance of power and weight, and they are more environmentally friendly than other types of batteries. However, they may have shorter battery life compared to other types.

III. Key factors to consider when choosing a kayak fish finder battery

When selecting a kayak fish finder battery, it is essential to consider these factors to find the best battery that meets the user’s individual fishing needs:

  • Battery capacity: Battery capacity is critical, as it determines how long the battery will last before requiring recharging. The larger the battery capacity, the longer it will power a fish finder, but it also means a heavier and more significant battery that might not fit easily into the kayak.
  • Weight: Battery weight is key to consider, particularly for kayakers who want to conserve valuable storage space and minimize the weight of their gear. Consider a lightweight battery that won’t take up too much space in the kayak or paddleboard.
  • Size: Battery size, particularly its width and height, is critical to consider to prevent any hassles of carrying the battery when paddling. A large battery can limit the storage space of the kayak and the anglers’ movement.
  • Durability: Battery durability is an essential factor to consider. Make sure to choose a battery that is built from quality and tough materials, durable enough to withstand the saltwater and harsh conditions in the water
  • Price: Lastly, price is a determining factor when choosing a battery, and choosing the best kayak fish finder battery that balances features and price is essential.

V. Tips for proper maintenance of kayak fish finder batteries

We strongly recommend following and applying the following tips to maximize the lifespan of your kayak fish finder battery:

  • Store battery in a cool, dry place: Extreme temperatures can damage the battery’s cells and significantly reduce its lifespan. Keep the battery in a dry and cold place and away from direct sunlight.
  • Check battery water levels regularly: In the case of sealed lead-acid batteries, it’s important to ensure that the battery water levels are enough. It’s recommended to monitor battery water levels every three months.
  • Clean battery terminals and connectors: After every use, clean the battery terminals and connectors to remove dirt and debris that can damage the battery’s cells.
  • Charge the battery after every use: Make sure that the battery is fully charged after every use. It’s crucial not to store the battery uncharged, reducing its overall lifespan

Proper maintenance of the battery contributes to longer battery life and aids in preventing the need to purchase a new one to replace an undoubtedly damaged one.

VI. Alternatives to a standard kayak fish finder battery

Alternative to traditional kayak fish finder batteries that come in handy on extended trips and for kayakers who need to charge gadgets include:

  • Solar panel chargers: Portable solar panel chargers use solar energy to charge the battery. They are environmentally friendly, cost-effective, and an excellent backup solution if the battery dies unexpectedly. In sunny weather, they can charge a battery rapidly.
  • Hand crank chargers: These portable chargers operate by turning a crank, converting mechanical energy into electrical energy to charge the battery. They are reliable and require no external power source except human effort, a significant benefit on extended trips or in emergency cases.
  • Portable power banks: These power banks are an excellent option for those who need a small and portable power backup. Portable power banks specifically for outdoor activities have built-in solar panels that aid in charging on extended trips.

These alternative options offer flexibility and ensure kayakers can power their fish finders and gadgets even without electricity.
