One of the most affordable types of batteries on trolling motor battery the market, wet cell trolling motor batteries are capable of handling frequent drains and recharges while being relatively durable. If you’re looking for a budget-friendly trolling motor battery, then a wet cell is a good option. Deep-cycle lithium marine batteries offer the most lightweight and long-lasting battery for a weekend on the water.

Some people claim to be able to get as many as 10 years from one AGM battery, whereas others state only getting 2 or 3 years. Another big factor that determines how many seasons you get from your AGM battery is the charger you use. If you invest in a great charger that is recommended by the battery manufacturer, you have a higher chance of getting a longer life cycle out of your battery. This is a pure, non-alloy lead design with some of the most advanced technology included. Compared to the competition, this battery has a super-fast recharge and a long lifespan.

Of course, how much exactly you’ll want depends on your specific motor. The VMAX MR127 has the power, performance, and construction found in more expensive AGM batteries at a lower cost. This AGM battery has the same recharge and discharge rate and cold-cranking amps as similar batteries. With 200 minutes reserve capacity, the VMAX has plenty of power for trolling motor, electronics, and starting. The Optima battery is a dual purpose battery, meaning it can be used both on deep cycle applications or starting applications.

And here are several things you should pay attention to in order to get a good trolling motor battery. You may also follow this video to see the hand-on differences between different types of the electric trolling motor battery. And within that range, the Lead Acid Wet Cell batteries and Sealed AGM trolling motor batteries are the two most popular choice for anglers, each with their own pros & cons.

To do this, buy a battery level indicator and maintain 50% or higher. If possible, you should recharge your battery to 100% after every use. This is no surprise since you’re splitting the battery in two to perform both a cranking battery and a deep-cycle’s job. When purchasing, come into your search with a price range and a few characteristics in mind. With a lower price, there’s a chance you’ll lose some advantages.

Since this one is designed with AGM technology it requires very little maintenance, a strong powerful turnover, and a fast recharge. This is an excellent battery for serious anglers who care about their fishing. Whether you need one trolling motor battery or three of them, that’s the first guideline, but there’s more to it than that. And of course, if bargain basement batteries aren’t up to snuff in the first instance, you were penny wise and pound foolish. This is a pretty “vanilla” battery, but that’s meant in a really positive way. It’s proven technology, works with a variety of chargers, and will most definitely not break the bank.

The Amp-Hour Rating determines how long a battery can provide power to a trolling motor before recharging or replacing it. The higher the Ah rating, the more charge the battery can store and the longer it can power the motor. A deep-Cycle battery can run at full capacity for 4-6 hours (depending on size and brand). But when using them with a trolling motor, they’re not recharged by an alternator like an engine.

Lithium Trolling Motor Battery

Its dimensions are 10.75” x 6.75” x 9.1” and it weighs roughly 45 lbs. The sealed unit allows the battery to be mounted up to a 45-degree angle without the need to worry about spills and leaks. Unlike other wet acid batteries, it is sealed to prevent leaks and spills making it easy to mount at various angles without worry. The AGM technology helps bind the batteries cells together and contains the electrolytes, therefore, making it spill proof.

Here’s our pick of the best trolling motor batteries on the market. And don’t miss our extensive trolling motor and electric outboard test. Customers find that the battery holds a charge for a long time and lasts all day. They appreciate its lightweight design and functionality, with one customer noting it performs as well as advertised.

Trolling motor batteries used several times a week should last no less than three or four years, and possibly five or six with no loss of charge. The Optima Bluetops incorporate AGM design into a frame that’s lighter and substantially more compact than the often-unwieldy AGMs from other manufacturers. That means you get the incredible runtime and the high number of recharges this category provides, but without the space-stealing footprint of the competition.

These batteries are sealed completely, and it is fit for everyday uses of a trolling motor. They consider it an excellent value, and one customer mentions it powers fish finders effectively. The durability receives mixed feedback, with some praising its quality while others report it doesn’t last long. With Black Oak’s Trolling Motor Batteries, you’ll never have to worry about running out of power when you need it most. Our lithium batteries offer industry-leading performance with fast U.S.-based support and an 11-year warranty to back every product. Whether you’re upgrading your boat’s battery system or need reliable power for long fishing trips, trust Black Oak to deliver.

The sealed lead acid used in batteries is an unstable substance, and the absorbed glass mat contains the acid effectively (so it can’t spill). The absorbed glass mat also stabilizes the plates inside the battery, making it much more difficult for them to shift. If you have a longer, heavier boat, you’re obviously going to need more lbs of thrust out of your trolling motor. This might mean a decision to use a 24 or 36-volt trolling motor. Perhaps you always bring a group, carry extra weight for other reasons, or often fish against wind and current.

By contrast, car batteries work in a pampered environment, and it’s important to keep that in mind. But they require proper ventilation, can leak and spill acid, don’t hold a charge as well in storage, and can be damaged by the vibrations typical in marine use. Unfortunately, battery tech is confusing, and unless you really do your homework, you’ll shortchange your motor and yourself.

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.

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.

Starter batteries are designed to give a short burst of high current, more than 200 Amps at a time. Like other deep-cycle batteries, lithium batteries are designed to provide a steady amount of current over a longer period. While it is technically possible to use a lithium battery as a starter battery, it is not recommended. Traditional marine batteries suffer from constant voltage drop as you use them. And if the voltage is too low, your trolling motor may stop altogether, even though some power is still left in your battery.
