You don’t have to worry about spills as it is AGM/SLA spill-proof. In addition, this battery can recover quickly from repeated deep discharge. You’ll be able to use it for a long time without worrying about replacement anytime soon. In other words just take the Ah rating of the battery, divide it by the current the appliance draws and, bingo, you know how long it will last.
These batteries refer to the cells in the battery immersed in a solution of sulphuric acid and water. This battery requires maintenance as per frequent usage and overcharging. It is recommended to check the battery before using, to make sure adequate water is in the battery. You can add purified water if the water level is down to prevent the battery from being damaged.
It operates well in cold climates and extreme weather and packs a powerful punch when starting the engine making it an ideal choice for those in temperate climes. It also promises fifteen times vibration resistance for durability. 100 Amp hours (Ah) of capacity is optimal for larger 24V trolling motors. When it comes to marine batteries or trolling motor batters, you have your typical 12-volt lead acid batteries, AGM (or Gel Mat) batteries and you have lithium batteries (LiFe PO4). These can be used to start an outboard, power lights and pumps, power multiple electronics and fish finders and run a 12, 24 or 36-volt trolling motor. One of the key components are that the batteries are waterproof.
But they don’t like sudden, powerful discharges, which can lead to damage to the plates. And they must be recharged carefully, never exceeding a maximum charge. And like the battery in your car or truck–which is also a starting battery–they need to be more or less constantly recharged via an alternator or on-board battery charger. Letting them discharge and then recharge will quickly damage the battery, resulting in failure. These are dedicated trolling motor/electronics batteries, and they’re what you’re looking for. If weight is an issue for your boat, and if you don’t mind the extra maintenance issues of old-school, wet-cell tech, the SRM-27 is a good buy.
Since the electrolyte is totally absorbed by the AGM, the VMAX is classified as “non-spillable and non-hazardous”. A tough tank seals and protects the tightly packed plates delivering the VMAX in a 100% maintenance-free package. Though VMAX tanks are best known for their long life span, their capability to recover after repeated deep discharges is what makes them the favorite choice for any application.
With proper voltage matching, smart charging practices, and certified safety features, anglers can achieve 8-12 hours of continuous runtime. Invest in quality BMS-equipped models from reputable brands to ensure 10+ years of reliable service across thousands of charge cycles. Selecting the ideal lithium battery for a trolling motor requires evaluating voltage compatibility, amp-hour (Ah) capacity, weight, charging speed, and cycle life. Lithium batteries outperform lead-acid alternatives with 2-3x longer lifespans, 50% weight reduction, and consistent power output.
Deep-cycle batteries are designed to be drained and recharged over and over. A 12V 100Ah battery typically lasts from four to eight hours on a trolling motor, depending on factors like motor thrust, speed, and water conditions. At lower speeds or with intermittent use, the battery may last closer to eight hours, while operating continuously at high speeds will considerably reduce your runtime. The manufacturer also offers a nice four- year warranty on the battery.
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.

Customers are satisfied with the battery’s functionality, with one customer noting it performs as well as advertised. Connect-Ease is a Minnesota-based company with a passion and mission to develop innovative practical products that allow sportsmen and women to enjoy more time in the great outdoors. Geoff started fishing as a child in the gorgeous lakes of Mammoth, while on family vacations. This might be a good compromise if you’re thinking of going with an extra battery, and want to keep the price down.
A cranking (also starting) battery is designed to give a high burst of amps for a short period of time. After the starting battery has done its job, it isn’t required by the car to provide any more energy. Instead, the alternator works to restore any spent energy released by the battery. Car batteries are not designed to be able to provide sustained power to accessory devices. Before we get into the characteristics of deep cycle batteries themselves, it seems wise to take a look at how much thrust power you need. Consider the fact that your overall boat weight is an inconstant factor (you might bring an extra buddy, and some extra gear, coolers, etc. sometimes).
If you have a kayak that has a 24-pound thrust motor, you can low speed drive it for more than 2 hours and the batteries are still going to be at full charge. By doing so, the mat protects the lead plates inside from touching each other thereby protecting the plates from deteriorating quickly extending the lifespan of the battery. There is an absorbed glass mat sealed inside the battery to keep the lead plates from breaking down quickly. You just need to do your research to see which type of battery meets your needs. If you are looking for batteries that have a long life and deliver excellent performance, consider buying AGM batteries or Lithium-ion batteries. For lead-acid batteries, the deeper a battery is discharged, the lower its capacity and run time will be.

A lead-acid wet cell battery typically lasts between 2 and 4 years with proper maintenance. AGM and lithium batteries may last longer, with some lithium batteries boasting a lifespan of up to 10 years or more. Whether you’re a seasoned angler or a first-time boat owner, this guide will provide you with all the information you need to select the right trolling motor battery for your needs.
Armed with this information, you should have much less trouble tracking down the best trolling motor battery. In contrast, “cranking” batteries, like those found in a car, are designed for a high-power output but minimal discharge, such as when starting an automotive engine. The harder your motor has to work, the faster you’ll deplete your charge. Most users should buy the battery with the highest amp-hour capacity they can afford.
Frankly, the size was somewhat of an issue for me, as this battery is rather bulky. Nevertheless, the above-average runtime, huge reserve capacity, AGM design, and price still make this battery the cream of the crop. AGM batteries are similar to flooded, except they use a fiberglass mat to hold the liquid in place. AGM batteries also have more mounting options, and they can take a beating. In fact, the best AGM battery discharges power more efficiently than a flooded wet-cell battery.
However, if you have a 36V system you have a lot more leeway with one cell shutting down the battery. Ultimately, 36V systems in parallel are actually a better choice for anglers than three 12V batteries in a series. Your 12-volt batteries have 12V controllers and are somewhat limited on managing a 36V system. A 36V controller is way better equipped to handle your 36V power environment in each battery and as a system. One of the most notable features is the battery’s Bluetooth 5.0 connectivity.
