Purchasing a trolling motor battery might not be the most glamorous job, and it might not have the same excitement attached to it as buying a new rod or a brand new kayak. The fact is very simple though: getting the best possible trolling motor battery is absolutely vital, as it is an integral part of any fisherman’s kit.
So, instead of putting off purchasing a new trolling motor battery, and spending your hard earned money on something more exciting, perhaps it’s time to invest in this important piece of equipment? But what should you consider when buying a trolling motor battery though? Well, there are three important considerations to make…
The first thing to look at is how long they hold their charge for. After all, if you are out on a long fishing trip, the last thing you want is for your battery to go flat! All good makes of trolling motor batteries will be rechargeable, but do you want to be recharging them constantly and running up your energy bills?
It’s also really important to consider how safe the batteries are, in terms of keeping the potentially harmful substances locked away in them. Good trolling motor batteries will have a spill-proof design, which means that any battery acid isn’t able to escape, even in the worst conditions. The big advantage to this is that it means that batteries can be placed anywhere in the boat, without any risk.
Finally, it’s really important to consider your boat’s weight, as you’ll need to be able to purchase a battery that can provide the thrust needed to propel your boat effectively. After all, do you really want to be chugging through the water slowly, or would you rather get to your favorite fishing spot as soon as possible?
The final thing to say before moving onto looking at the best trolling motor batteries is this: try to avoid using a standard SLI-type battery, such as the ones used in cars. They might work, but they are not ideal and, over time, could well damage both the battery and the motor. Spend a little cash and get something built for the job, and you won’t have problems in the future.
So, what are the best trolling motor batteries out there? Below, you’ll find five that come highly recommended by anglers throughout the country…
Wilderness Tarpon 100
The Wilderness Tarpon 100 is a fantastic trolling motor battery, built specifically for kayakers. It has a really small size, making it easy for smaller kayaks to transport, and also weighs very little. What’s more, it features Absorbent Glass Mat technology, meaning that you’ll be able to extract every last bit of power from it. When not being used on a kayak, it can also be used for a multitude of other purposes.
This trolling motor battery is also spill proof, meaning that it can be placed in any compartment, nook or cranny in your kayak. Finally, it is also pretty cheap and can be purchased for around $65, but still manages to stand-up well to other, more expensive, batteries. All in all, it’s a great choice for those on a budget, but who still value reliability and performance.
Optima Batteries 8016-103 D34M
Optima Batteries are generally considered to be the gold standard in this area, and are trusted by people all over the world. This deep-cycle 12v battery is lightweight, making it perfect for smaller boats and kayaks, but still manages to put out a lot of power. What’s more, Optima Batteries promise that it has 15x vibration resistance, therefore leading to great longevity. It’s also a great choice for those heading into harsher weather conditions.
Perhaps the biggest selling point of this battery is its SPIRACELL technology though, which ensures that it holds its charge for long periods of time, and can also be recharged quickly when needed. It is slightly more expensive than many other trolling motor batteries on the market, however the extra cost leads to much better results.
VMAX is another company noted for their high-quality trolling motor batteries, which can be used for a variety of different applications. This specific battery promises to power a 40lb thrust motor for around 3-5 hours, providing it is running at a low/medium speed. It offers AGM technology for enhanced performance, plus it has an extremely low self-discharge rate. With a weight of 32lbs, it’s not the lightest battery on the market, but it is still more than acceptable.
The VMAX MR86-50 is maintenance free, meaning that it’s perfect for those with little or no technical know-how, and it is renowned for its durability. If you’re looking for a trolling motor battery that won’t let you down, this could well be the best choice.
This 12v battery is completely maintenance free, and also comes with sealed silver calcium lead acid technology, meaning that it is incredibly safe. The charge indicator will let you know when the battery is close to running out of power, giving you time to get back to shore and recharge it, ready for another stint on the water.
When not in use, its low self-discharge rate means that it will retain much of its power, and it is able to withstand hundreds of recharging cycles, meaning that it should last an incredibly long time. What’s more, the price is also reasonable, coming in at around average cost.
Universal Power Group UB12350
The final trolling motor battery on the list is this offering from Universal Power Group which, like many other batteries, has AGM technology incorporated into its design. It certainly won’t break the bank, as it is one of the cheaper batteries on the market, however it does compare well to many other, more expensive, batteries.

It will generally provide power for around three hours when kayaking, which should be enough for those looking to spend shorter amounts of time on the water. It can be used in any position, thanks to its spill proof technology. What’s more, it is waterproof and recharges very quickly, plus it is lightweight, which allows for easier transportation.
Lightweight trolling motor batteries
A lot of the batteries listed above are very heavy, usually tens of pounds, making it quite a pain to lug around. Ideally, it’ll be fixed in your boat, but you’d still like to be able to move it around without having to go through a huge hassle.
As far as lightweight trolling motor batteries are concerned, you have a couple of options.
One is to use a jump starter instead of a regular battery. Jump starters have far less capacity than the usual lead acid batteries, but they weigh almost nothing compared to lead acid packs.
This battery is a good option – it’s lightweight at 18 pounds and delivers a decent amount of peak amperage.
The second option is a Lithium Ion battery. This battery is super expensive at $1300, but this battery is top of the line and a superb, power-dense replacement for any application of lead acid batteries.
This battery gives you 108 Amp hours from just 28 pounds of weight, and it also has many safety mechanisms built into it.
