Longest Lasting Trolling Motor Batteries: Our Top 7 Picks

The market abounds with marine batteries of varying specs and by several different brands, and making the right choice from the pack can be a really difficult task.

But we’ve done all the hard work for you. We’ve hit the market to compare several marine batteries in terms of durability, performance, other specs, buyer reviews, and brand trust. And after several hours of thorough comparative research, we were able to figure out those that hold charge for the longest periods and that last for years before dying out completely.

And here are our top recommendations.

1. Weize 12V 100AH Deep Cycle AGM LFP 12100

longest lasting trolling motor battery


Weize LFP 12100 is a highly rated battery that is known for its ability to provide power for quite a long time between discharge cycles. There are many reasons to invest in this battery.

For starters, the manufacturer optimized the design of this model to make it more efficient in the storage of DC power. An additional perk of the optimization is that you get a stronger performance than what other batteries with the same capacity offer. In other words, you can expect more power longer than standard batteries because it can be nearly discharged.

Additionally, the Weize LFP 12100 stands out in terms of the ability to recover from a state of deep discharge. Some deep cycle batteries struggle to recharge properly when they reach a certain level of discharge state but this problem is almost non-existent on the LFP 12100.

While the LFP 12100 delivers long-lasting performance, you will have to make sure that you charge it fully always to avoid a chemical reset that prevents it from fully charging in the future. Also, it is recommended to avoid instances of extremely deep discharges over and over again as this may cause the same issue.

Although the battery boasts a compact design, it still heavy and you may need to flex your arm muscles to move them around. The LFP 12100 comes with a 30-day refund policy attached to a 1-year warranty, so you can expect Weize to stand behind their product.
