How Long Will 7ah Battery Run My Fish Finder? [Expert Review!]


Sharing is Caring


Your fish finder’s battery might as well be an extension of yourself; it can be your constant companion on your fishing adventures and an indispensable part of your catching game. When your battery finally gives out, you’ll have to throw it away and buy another, which is why you might want to consider just how long each battery lasts before you need to replace it.

Luckily, there are a few things you can do to increase the life of your battery and make long, happy hours of fishing even more enjoyable. Today, we’re going to tell you about four ways you can make your life on the water more convenient and how long each battery life-extending method will get you.

Use An Innovative Charging Dock

When it comes to keeping your devices powered up and in good working order, modern life doesn’t get much more convenient than the charging docks available today. These devices allow you to keep your phone, tablet, or laptop powered up and ready to go whenever you need while also avoiding the hassle of constantly plugging them in and having them turn off whenever you leave your vicinity.

If you’re planning on using a fish finder for a lengthy period of time, consider investing in one of these docks so you can keep your device powered up and ready to go. The convenience of being able to pull it out whenever you need it along with the fact that it will remain powered up even when left on the dock for a while will make a sizable difference in how much you enjoy your time on the water.

Install A Water Charging Station

If you’re out on the water a lot, you might consider investing in a water charging station. These are devices that are specifically designed to keep your boat’s electrical equipment powered up and in good working order while also preventing the damage that can occur from regularly charging your devices on an open circuit.

The convenience of being able to fill up your boat with fresh water at any time and the security of knowing your devices will be well-charged even when left in the water will be a few of the things that make water charging stations valuable additions to your boat.

Use High-Quality Batteries

If your device uses high-quality batteries, you might be able to get away with using a cheap, throwaway model. However, if you’re planning on using a fish finder for a lengthy period of time, it’s generally recommended that you invest in some high-quality, rechargeable batteries so you don’t end up having to keep replacing the models that eventually degrade.

While it’s convenient to use a cheap battery that you know can be replaced when it dies, investing in a high-quality model that you know will last longer will have plenty of advantages. Not only will the battery last longer, but you’ll also avoid worrying about whether or not it can be replaced when needed.

Avoid Using Your Fish Finder In Cold Water

If you’re new to fishing, it’s highly advisable to start out using your fish finder on relatively calm, still ponds. This is usually the best way to get a feel for how well each model works and what features it has that make it valuable. Once you’ve familiarized yourself with how your device functions, you can move on to areas with deeper water where larger fish may be present.

The cold water will not only prevent your fish from being able to sense your presence, but it will actually shrink the range at which they can hear you. This makes it more difficult to pinpoint their location and bring them in for the catch. As an added bonus, the cold water will keep your fish fresh, so you won’t have to worry about them going bad before you can use them.

Even experienced fishermen have found it beneficial to keep their fishing tackle boxes and ice boxes separate in order to prevent ice from spoiling the fishing trip. As you’d expect, the separation of these items leads to less of them getting damaged and broken, especially since there’s less of them to begin with. If you’re planning on using a fish finder for a lengthy period of time, it’s advisable to keep its location in a relatively cool place so it doesn’t begin to deteriorate quickly. This is especially important if you’re using a gas-powered model; the additional strain that the cold air would put on the engine might cause it to stop functioning properly or even break down completely.

Consider An Air Pressure Regulator

If you’re out on a blustery day with little or no breeze, it’s highly advisable to invest in an air pressure regulator. These devices are essentially miniature pressure vessels that regulate air pressure for your equipment as you would expect. In addition to keeping your equipment in good working order, they can also prevent damage from rapid changes in air pressure that accompany heavy wind or waves. Rapid changes in air pressure can cause things to malfunction or burst, especially if you’re using a gas-powered model.

The convenience of having everything you need in one place while on the water and the peace of mind that comes with knowing your device will be protected from water damage are a few of the reasons why you might want to invest in an air pressure regulator. If you’re planning on using a gas-powered fish finder for a lengthy period of time, it’s generally recommended that you invest in one that can handle rapid changes in air pressure so you don’t have to worry about your equipment suffering damage.

With these tips in mind, you’ll be able to keep your fish finder’s battery functioning long after your initial investment. Not only that, but you’ll also be able to enjoy your time on the water more than ever before because you’ll have less of a distraction worrying about whether or not your battery is going to die soon.
