Customers find the battery easy to use, with one mentioning 36V lifepo4 battery it’s convenient to handle in the boat and another noting it’s particularly suitable for older fishermen. Customers appreciate that the battery is relatively light, with one customer noting it weighs less than 40 lbs including the case. Customers are satisfied with the battery’s charge rate, noting that it comes almost fully charged and charges well, with one customer mentioning it charges quickly. It has been tin-plated and has great deep cycling capabilities, around 400 Cycles at a depth of discharge of 80%.

It weighs around 75 lbs, and the dimensions are 12.9 x 6.8 x 8.5 inches and have a power capacity of 120 AH. Hence, it is an ideal trolling motor for your Jon boat, giving more power with higher amperage. The service life of this trolling motor is about 8 to 10 years.

So if you find the motor to be very weak after a day’s use or against the current, upgrading the trolling motor battery group 27 to group 31 could be helpful. They’re powerful and reliable, even in very hot or icy environments. Still, if you anticipate using your trolling motor on rough water, a leakproof AGM or lithium-ion battery would be a better choice. This battery is a great trolling motor option if you use a tandem fishing kayak or a small boat.

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.

As one of the best 12V 100Ah lithium battery for trolling motor, the battery is perfect for trolling motors with thrust ratings between lbs. It provides up to double the runtime of traditional AGM batteries, while weighing 1/3 less (only 22.16 lbs total), improving boat speed and efficiency. The best marine battery for a trolling motor, according to our recommendation, is the 12volt deep cycle marine battery. It needs to have at least a 110 amp hour rating, and ideally, it should be of 27 sizes.

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.

However, performance doesn’t deteriorate with repeated discharging/recharging. On the downside, this is the least environmentally friendly type of battery. If you need a battery that will work in all weathers, even in extreme cold, you need an AGM battery – short for absorbed glass mat.

Each of these options has unique benefits and applications, ensuring that there is a battery to meet every mariner’s need. The has been constructed with top technology, which regards the acid inside the battery. None other than the Absorbed Glass Mat technology allows for a low-maintenance and spill-proof battery. It provides 12 volts with 34 Ah and can be safely mounted in any given position. Not only is this affordable, but it also cuts any risk of corrosion or leakage due to the highly porous absorbent glass mat.

Below, we’ll get into the specifics of each, making your decision easier. As mentioned earlier, I brought this motor out to sea for 8 hours straight. Then, once I got home and put the battery on charge, it was still well above 90% 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.

Get Enough Reserve Capacity

Universal Power Group Battery is a spill-proof battery that is praised by a lot of anglers. The battery is made with a thick Abs plastic casing and is resistant to shock and vibration. It also has a low self-discharge rate, so you can be sure that it will work perfectly even after being stored for a long time.

Just as the name implies, the starting batteries (aka cranking or starter battery) are designed to start a motor smoothly with short and strong bursts of energy. They are not designed for multiple discharge/recharge and draining it can cause damage. If you are in a hurry, here we’ve compared all popular trolling motor battery options and hand-picked the top 5 that can easily fit in Minn Kota and other trolling motors on the market.

Staying with the internals, the AGM design allows for little to no maintenance with a spill-proof design. Not to mention, the center-placed terminals allow you to mount this battery in almost any direction. This means no more hassle trying to get negative terminals on one side and positive terminals on the other. For more than 125 years, Field & Stream has been providing readers with honest and authentic coverage of outdoor gear.

Marine Enhanced Flooded Batteries (efb): Power Beyond The Ordinary

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.

With 120 amp-hours to call on, you won’t even need to charge this battery after every trip. This reliable battery is a big unit, but it’s a very reliable option if you’ve got the space. The one drawback of having all this power is the battery is on the bigger side. It weighs a whopping 68 lbs and measures 7” x 9” x 12”, so it’s not going to fit in some smaller boats and will add a good bit of weight to your overall capacity.

That said, the Autolite unit has plenty to offer, not least of which is its formidable Ampere hour rating. In practical scenarios, this calculator can assist in both short-term plans and long-term strategies. For example, a weekend fisherman can use it to optimize battery usage for a single outing, while a tour operator might rely on it to ensure consistent service over a season.

Lithium batteries offer significant benefits that are hard to ignore. Some makers may ask you how your batteries have been charged and used, which could make your claim problematic. Maintenance is straightforward, as a built-in BMS usually takes care of your battery’s health. Power Queen 12V 50Ah offers over 4000 cycles, which is more than ten years of typical use. For example, a Minn Kota Terrova 55 has a maximum amp draw of 50A.
