The Best Fish Finder Batteries for Those Long Fishing Trips

The Best Fish Finder Batteries for Those Long Fishing Trips

Fish are tricky creatures. Figuring out where the best fishing spots can be a bit hit or miss, and that’s why so many people who make the effort to go fishing come home empty-handed.

If you’re a big fan of fishing but not so keen on the fish finding, a fish finder could drastically impact your success rate out on the water. A fish finder, or a fish sounder, uses sonar to help find fish underwater. It saves fishing fans a lot of time and disappointment because it provides greater certainty about where the fish actually are. Some models also have GPS functionality too, which can help you stay safer on the water. But a fish finder is only as good as your fish finder battery.

Fish finders need reliable batteries in order to work. Before you go out and buy any old fish finder battery, you need to think about a couple of things first: voltage, size and brand.

Voltage

High-voltage fish finder batteries will always work better than lower-voltage alternatives. This is especially important if you’re fishing in choppy conditions, whether it’s from a boat or a kayak. If you’ve got the choice, always go for a higher-voltage option; your brag photos will thank you for it.

Size

When it comes to fish finder batteries, size doesn’t matter. As long as the battery you choose can supply enough power for a long period of time, physically smaller battery sizes might actually be better.

Larger batteries could give you the illusion of performance, which isn’t helpful when your vessel has weight restrictions (like kayak fishing). If you’re using a boat to fish from, size probably is less an issue than performance.

Brands

There are a lot of options on the market – some awesome, some not so much. Do your research and ask for recommendations before you go out and buy any old fish finder battery that might not end up being a great option for your needs.

Battery Types

The best fish finder batteries on the market tend to be lithium batteries. They’re small and lightweight, and they perform much better in cold weather than their SLA alternatives. As they drain in power, they continue to work at 12V until they die altogether, and they can be recharged over and over again which means you don’t have to buy as many. Lithium batteries are pretty expensive though.

SLA batteries are cheap … but that might be the only benefit. SLA batteries can be really heavy which might not be the best choice if you’re fishing from your kayak, and they generally don’t perform well in the cold. They’re also not designed to last very long, and as an SLA battery fades in energy the voltage will drop drastically too. A battery that drops below 12V can’t be used again until it has been recharged.
