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 48V lifepo4 battery 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.

 

50ah Deep Cycle Marine Battery

 

Now keep in mind, you might not want to get this as a cranking battery if you have an engine where it voids the warranty, like Yamaha. However, you can for sure with a Mercury outboard and probably other brands as well. So it’s more than enough to crank your outboard and power your graphs all day long. You will have to check it with your trolling motor manufacturer. Minn Kota motors, for example, are allowed to run on lithium batteries.

Most chargers have a shutoff and a trickle feature that will keep batteries topped off. Also, with wet cell batteries, make sure that water levels are adequate. If you have a bass boat or other medium-sized boat, you need a group 27 battery size, which is capable of delivering 110 amps per hour.

 

You may sometimes see batteries referred to by their Group number. This is a reference determined by the Battery Council Organisation and is related to the physical dimensions of the battery. But seriously, the Ampere hour is the unit of electrical charge, so the greater the Ah rating of a battery, the longer it will run. Housed in a vibration-resistant casing, the LXD100 has a low self-discharge rate, resulting in extended shelf-life when not in use.

 

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.

 

One of the most affordable types of batteries on 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.

 

I would rate this one right up there with the Optima BlueTop, which is considered one of the best batteries for trolling motors by many in the industry. If you’re looking for a reliable dual-purpose trolling motor battery then this 12V AGM battery is certainly worth considering. While most dual-purpose batteries offer starting power and decent deep cycling, this model has some of the better deep cycling functionality found in these types of batteries.

 

Its patented SPIRALCELL technology is an assurance that it has more running time, can be recharged fast, and it has longer life compared to marine batteries or any RV batteries. Optima batteries are tightly wounded to minimize plate movement and damages caused by rough conditions. It’s also spill-proof hence it is maintenance free as well as environmentally friendly.

 

Larger batteries are also recommended if you have a larger boat. The heavier the boat the more power is drained each hour, so a larger battery should be considered if you’re using a bigger watercraft. However, AGM batteries are much more expensive than wet cell batteries, so remember that the additional durability comes with a higher price point. That said because it ensures a longer-lasting battery, the extra price may end up paying for itself over the years.

 

Lithium-ion (Li-ion) batteries – this is the smallest type of trolling battery. Bear in mind that the lifespan of each battery is far from guaranteed just because it is either a wet cell or AGM. Some AGMs are better than others, meaning you may find one that lasts up to 4 years while others struggle to last this long. Should you have lots of weight capacity on your boat, then consider going for a heavier battery if it means you get a much-improved performance. The more durable the battery the longer it will last, so keep an eye out for features that highlight the durability of the battery.

 

It is a 12 Volt battery with an Amperage 55 AH; the chemical elements are AGM and SLA. It weighs 38.58 lbs, and the dimensions are 9.02 in x 5.43 in x 9.13 inches. Customers have mixed opinions about the battery’s durability, with some praising its quality while others report that it doesn’t last long. 12.8V 10Ah LiFePO4 battery is a best choice for alarm system, off-grid application.

 

Conversely, AGM and lithium-ion batteries require no maintenance, meaning you don’t need to worry about checking water levels or checking inside the battery for damage. Once you buy it you won’t need to do any maintenance, although it will cost more than batteries that need some maintenance. While this may seem like more hassle than it’s worth, wet cell batteries are very affordable so the need for minor maintenance may be worth the savings. For instance, a wet cell battery requires some infrequent maintenance, namely topping it up with filtered water and inspecting it for signs of corrosion and cleaning as necessary. Removing corrosion is easy enough, with a basic mixture of water and baking soda removing this with ease.

 

Also, this type of battery has the shortest lifespan, lasting 1-2 years, although this is reflected in the lower price. For a 24-volt trolling motor, you need two 12-volt batteries connected in a series. For a 36-volt trolling motor, you’ll need three 12-volt batteries in a series.

 

You are less likely to see a battery discharged, and a perfect purchase will last long. It shows good discharging vulnerability and can stand between 7000 (50%) to 3000 (80%) cycles. It is one of the best batteries of a quality/price ratio in this list. The capacity of 100 Amps provides at least five hours of continuous work. With a nominal 12V voltage, it gives away 12.8V of actual voltage.

 

For example, a battery rated for 100Ah can deliver this capacity only when discharged slowly over a 20-hour period, which means a current of 5 Amps. If you want to increase the current to 20 Amps, the same battery will give you only 80Ah, and the available capacity rapidly diminishes as you draw more current. Since a dual-purpose battery does two jobs, its lifespan isn’t as long as a deep-cycle marine battery. Dual-purpose batteries are more for long-term use and quick power.

 

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.

 

The battery has a CCA of 1150amps, so its starting power is excellent. So you can rely on it to run your boat and other electric equipment and tools for hours. And with a capacity of 100AH, you can fish for more than 5 hours before the battery needs a recharge. And AGM batteries have an advantage over standard batteries in that, the lead plates inside the batteries are cushioned with a fiberglass mat. Our battery run time calculator will give you an idea of what you can expect from a given battery capacity at a specific amp draw. When you have a rough idea how much power you draw and how long you draw it you can figure out what setup you need.

 

The SCM0035 is an easy to install, zero maintenance battery that is perfect for rough trolling. Please note any warranty included in purchasing the trolling motor battery. Contact the manufacturer right away if it does not last that long. Charging the battery with a trolling motor may be damaging if you do not use a deep cycle battery. To avoid this unfortunate situation, you need to choose a trolling motor battery that will give you the power and reliability you need to keep fishing. Customers find the marine battery works flawlessly all day without any issues, with one mentioning it powers their ice house.
