Recently, he’s expanded beyond that niche to include adventure travel and bluewater angling. Some Fish Finder Battery batteries have 10-year warranties, others have 3 months warranties. They are cheaper than AGM batteries but have a shorter life span. Lead-acid batteries can last for two years at best, but AGM batteries can last for more than 5 years. This is not the case with the Interstate Batteries, which you can place in any position in your boat because the battery is spill-proof.

One critical feature in the ODYSSEY batteries is that they are made with almost 100% pure lead (99.99% to be exact) instead of the traditional lead alloy that most AGM batteries employ. Pure lead is thinner than its alloy counterpart which allows for more plates in the battery, making for a more powerful and long-lasting battery. Of course, being an AGM means you can install it in any position without worrying about it leaking, so you should be able to squeeze it in even when short on space. This also means no maintenance or diminished performance from vibrations, with the battery being incredibly durable and reliable in most conditions. Another feature to like about this battery is that it is non-toxic and more environmentally friendly than other battery types such as lead-acid and even lithium-ion. In any case, it offers plenty of charge for most fishing excursions, save for those 12+ marathons that some anglers enjoy.

You can use it with more powerful motors and still expect plenty of runtimes, with the 100Ah lasting a good length of time even on more draining motors.

They also need to be easy to charge, simple to maintain, and reliable in all weathers and temperatures. There are lots of different models to choose from, so picking the right one is not always easy. An AGM battery has a longer life expectancy, usually between 2-4 years depending on the quality of the battery. These batteries have virtually no maintenance so you’ll likely get the maximum lifespan from an AGM unless you damage it or store it incorrectly. Also, the battery charger (check out our battery charger guide) is an important consideration. Those that bulk charge tend to offer better bursts of short charges, so they probably aren’t the best for fully recharging the battery.

 

That means it can deliver 100 Ampere hours of current to your trolling motor – so if your outboard draws a steady 20A, this battery would power it for 5 hours. Save time and eliminate the hassle of connecting and disconnecting your deep cycle batteries from your trolling motor with a pre-built wire harness from Connect-Ease. This battery though small packs some good power with 15 amp hours.
