  • Dimensions: 12.2 x 6.6 x 9.2 inches
  • Weight: 63.9 pounds

The Universal Power Group presents a top-quality offer here with this UB121000. It's a 12-Volt battery, perfect for running trolling motors, and it comes with a large 100 Ah capacity, which allows you to spend more time troll-fishing.

Universal Power makes it using Sealed Lead Acid (SLA) technology and this helps to keep its price competitive, making it our overall best battery for trolling motors. SLA batteries are spill-proof, maintenance-free, and need no topping off from time to time.

This battery measures 12.2 x 6.6 x 9.2 inches and weighs 63.9 pounds. It comes with a good vibration and shock resistance, and you're free to mount it in any position of your choosing thanks to its spill-prof design.

For cons, although it's competitively priced, there are still cheaper trolling motor batteries on the market. But keep in mind they may come with less desirable features. Universal Power backs it with a 1-year warranty.

Pros:

  • Top-quality sealed lead acid battery
  • Maintenance-free and spill-proof design
  • Delivers up to 100 Amp-hours of power
  • Backed by a 1-year warranty

Cons:

  • You can get cheaper offers

  • Voltage: 12
  • Amp Hours: 35
  • Dimensions: 7.7 x 5.2 x 7.1 inches
  • Weight: 23 pounds

Budget shoppers will love this Mighty Max ML35, a trolling motor battery that's compact, maintenance-free, and offered at the lowest price on this list. This makes it one of your top choices.

Other reasons include its lightweight design at just 23 pounds. This battery measures 7.7 x 5.2 x 7.1 inches and is a maintenance-free SLA battery. Its package includes the battery with installation screws, plus it is shock and vibration resistant as well, and you can mount it in any position.

The only major issue with it is its power capacity. This ML35 offers a 35-Ah capacity, which can be too small for some people, leading to shorter trolling durations. But if you only plan short fishing trips, then this lightweight trolling motor battery should work out just fine. Mighty Max also backs it with a 1-year warranty.

Pros:

  • Sealed lead acid battery good for trolling motors
  • Offered at a very low and attractive price
  • Comes with a 1-year warranty
  • Lightweight at just 23 pounds

  • Voltage: 12
  • Amp Hours: 35
  • Dimensions: 7.7 x 5 x 6.1 inches
  • Weight: 25 pounds

Absorbed Glass Mat or AGM batteries offer many advantages over SLA batteries. And so, this Vmaxtools V35-857 is an AGM battery, offering you a longer service life and improved user-friendliness.

It's a 12-Volt battery with a 35-Ah capacity, which makes it ideal for short to medium term trolling sessions. It also features heavy-duty construction and there's no need to add water, check gravity, or carry out any type of maintenance. Just install and use it.

  • Dimensions: 12.1 x 6.7 x 8.2 inches
  • Weight: 68 pounds

Vmaxtanks makes some of the best electric trolling motor batteries, so here's another offer from this reputable company. This one is the 100-Ah version and it also runs on 12 Volts.

It's a top-quality AGM with a heavy-duty design for long service life. This means heavier-gauge lead-tin alloys that provide a better performance, deliver more power, and last longer overall.

As with AGM batteries, this one costs more than competing SLA batteries. But, remember that it's a 100-Ah battery that's ready to serve serious fishers. It offers a tough tank with permanent seals, the ability to survive repeated deep discharges, and Vmaxtanks backs it with a 1-year warranty.

Pros:

  • Top-quality AGM battery
  • Offers a 100-Ah power capacity
  • Heavy-duty design for long service life
  • Backed by a 1-year warranty

Cons:

  • It's relatively heavy at 69 pounds

  • Voltage: 12
  • Amp Hours: 55 Ah
  • Dimensions: 10 x 6.9 x 7.8 inches
  • Weight: 43.5 pounds

Optima offers different batteries, but this is their 'Blue-top' battery with a light gray case, meaning it's a dual-purpose battery that works well for starting your outboard motors and then, additionally powering your trolling motor when you need it.

It also features a unique design that visually sets it apart from the rest, making it both remarkable in function and looks. This battery offers a 12-Volt design, with 750 cold cranking Amps or 870 marine cranking Amps for engine starts, and 55 Ah for troll-fishing.

Note that cold cranking Amps is how much power a battery can supply at 0°F for 30 seconds before its voltage drops below 7.2 Volts. Marine cranking Amps, however, refers to how much power it can supply at 32°F for the same 30 seconds.

The single disadvantage with this design though, is that you don't get the efficiency of dedicated deep-cycle batteries for trolling. But, it remains a great starter battery that can additionally power a trolling motor, plus, it comes with a 2-year warranty, making it one of the best trolling motor batteries out there.

Pros:

  • Dual-purpose battery for starting and trolling
  • Offers up to 55 Ah of electric power
  • Delivers 750 cold-cranking amps

Here's another attractively priced trolling motor battery, and this one features a 35-Ah capacity, 12-Volt system, an absorbent glass mat sealing technology, and a removable handle.

Asides from being an attractively-priced AGM battery, it's also average on many other features, measuring 7.7 x 6.4 x 5.1 inches and weighing just 22.9 pounds.

As the DCM in its DCM0035 model number shows, it's specifically designed as a Deep Cycle Mobility (DCM) battery and thus, offers all the benefits you can get. It's great for trolling, totally maintenance-free, and includes a valve-regulation technology to prevents spills.

The only issue it has is how far you can go with it because it's just 35 Ah. If you're the type that does short trips though, then it's probably one of the best interstate trolling motor batteries you can get and a great buy. Interstate backs it with a 1-year warranty.

Pros:

  • Compact sealed acid battery
  • Delivers 35 Ah at 12 Volts
  • Offers flexible mounting positions
  • Backed by a 1-year manufacturer warranty

  • Voltage: 12
  • Amp Hours: 75
  • Dimensions: 10 x 6.7 x 8.9 inches
  • Weight: 47.2 pounds

If 30- to 50-Ah batteries are too small for your intents, and 100 Ah also seems 'too much', then a 75-Ah battery like this Weize LFP1275 might be just what you need.

Measuring 10 x 6.7 x 8.9 inches, it features an AGM construction with a valve-regulated design to prevent spills and keep it maintenance free. It's also rated at 12 Volts.

This battery measures 9 x 5.4 x 9.1 inches and weighs 36.3 pounds, making it perfect for short- to medium-distance troll fishing. It's also offered at an attractive price, which comes as a result of its SLA construction.

So, for downsides, while it may not be as user-friendly as AGM or GEL batteries, it remains a great option at a great price. Mighty Max offers a 30-day refund policy and a 12-month warranty on it.

Pros:

  • Compact SLA battery with a maintenance-free design
  • Delivers 55 Ah at 12 Volts
  • Installs in multiple positions
  • Backed by a 30-day refund and 1-year warranty

It measures 12.8 x 6.8 x 8.5 inches and weighs 67 pounds. Weize, the maker, uses a lead-cadmium alloy for the grid, giving one of the lowest self-discharge ratios n the industry. It also comes with the longest lifespan in this list, with Weize rating it for up to 15 years of service under optimal conditions.

As you can imagine, a major issue with this trolling motor battery is the price. So, it isn't for hunters of the best cheap trolling motor batteries. The good news though, is that it's worth every penny in it.

Pros:

  • GEL trolling motor battery
  • Better lifespan than AGM and SLA batteries
  • Ideal for very deep-cycle operations
  • Comes with a 1-year warranty

Cons:

  • GEL deep cycle batteries cost above average

How to Buy the Best Trolling Motor Battery

How to Buy the Best Trolling Motor Battery

Photo: pontoonopedia.com

The following paragraphs list the most important features to look out for when deciding on the best trolling motor battery for your boat.

1. Dual Purpose Vs Deep Cycle Batteries

This is one of the early decisions you'll have to take, as it matters a lot. There are starter batteries and deep-cycle batteries. A starter battery is designed to start a big engine using a large burst of electric power, while a deep-cycle battery is designed to power an electric device for a long time.

As you can see, a deep-cycle battery like the Vmaxtanks R127 is the perfect battery for your trolling motor. But that means you'll also need a separate battery to start your boat's engine, and this makes two batteries on board.

A dual-purpose battery, such as the Optima OPT8016 tries to solve this problem by its ability to provide large bursts of energy at startup and a slow but steady flow when you need to power your trolling motor. The major downside is that most dual-purpose batteries don't last as long as deep-cycle batteries. So, it's left for you to make your choice.

2. Construction & Battery Type

Another battery difference worth noting is its construction method, which determines its type. The two most popular battery types for trolling motors are the Sealed Lead Acid (SLA) and Absorbed Glass Mat (AGM) batteries. Here's a closer look at them, including a third type.

SLA Batteries. Sealed lead-acid batteries are a modification of the original flooded batteries. With SLA batteries, however, the user has no access to the individual cells and there's no need to top-off the battery with electrolyte. This makes them more user-friendly than ordinary flooded batteries. SLA batteries usually last for 2 - 3 years and a good example is the Mighty Max ML35.

AGM Batteries. With absorbed glass mat batteries, you get a more efficient battery design with a suspended electrolyte in glass fibers that works better with the battery's plates. AGM batteries are also sealed, they maintain their charges longer, they are lighter, spill-proof, and typically last up to four years. Optima OPT8016 is a great example.

GEL Batteries. Here, an additive is introduced into the electrolyte to stiffen it and turn it into a gel. So, the difference is that while an AGM battery is technically still a wet-cell battery, a GEL battery is completely dry. Their major advantage is in very deep-cycle operations. Else, GEL batteries are costlier than AGM batteries and often more difficult to maintain. A typical GEL battery is the Weize LFP12100.

3. Battery Voltage

Most deep cycle batteries run on a 12-Volt system and connecting two such batteries in series will create a 24-Volt system. Voltage is a measurement of tension in an electric system and you can easily damage your motor or other gear when you use the wrong voltage. So, always check first and make sure you are using a 12-Volt battery for a 12-Volt motor or a 24-Volt battery for a 24-Volt motor.

4. Amp Hour (Ah) Rating

This is another important metric you should keep in mind when making your choice. An Amp-hour refers to the amount of electric charge you release when you let one Amp of current flow for one hour. It's a very important rating for batteries because it shows exactly how much power you can store in it.

You'll need to check your fishing needs to determine the exact Amp-hour capacity that might be right for you. Small batteries will range from 25 Ah up to about 50 Ah, while larger batteries will reach 100 Ah and beyond. Keep in mind that the higher the Ah-rating, the longer the battery will last on a full charge.

5. Cold Cranking Amps (CCA)

This metric is only useful with dual-purpose batteries. It shows how much raw power the battery can produce when used to start an engine. This is usually measured in the first 30 seconds and at 0°F.

6. Cycles & Lifespan

While starter batteries won't last long if you discharge them beyond 50% often, deep-cycle batteries are designed to survive deep discharges before recharging. However, you need to keep in mind that a lower discharge before a recharge will prolong the battery's life.

For instance, a battery that loses only 30% charge before getting fully recharged every time, will last longer than a battery that loses 50% charge every time before getting recharged.

Conclusion

We've reached the end of this trolling motor batteries review and you've seen all the top offers out there, including sealed lead acid, AGM, and GEL batteries. Now's the time to choose.

If you just want an all-round great trolling motor battery, then our recommendation is the Universal Power UB121000. It packs 100 Ah, is fairly priced, and comes with a 1-year warranty.

For budget shoppers, we recommend the Mighty Max ML35, with its compact design, lightweight, and 1-year manufacturer warranty.

You could also desire an affordable heavy-duty battery, in which case we recommend the Weize LFP1275, with its 75-Ah rating, attractive price, and VRLA design.
