How To Find The Best 36V trolling motor battery For Your Boat

A trolling motor battery can be a big investment, so it’s important to make sure you’re getting the right one for your boat. Trolling motors are used by boaters of all skill levels and in many different types of boats. These motors are great for helping you navigate through shallow waters and over rocky terrain, but they can be very expensive if you get the wrong one. And while some brands have good reputations for their durability and performance, others may be a better fit for your needs. This guide will help you choose the best 36V trolling battery for your boat!

Battery CCA (Cold Cranking Amps)

Cold Cranking Amps (CCA) is a measurement of how much current a battery can deliver at 0 degrees Fahrenheit for 30 seconds. The higher the CCA rating, the better your battery’s ability to start your boat in cold weather conditions.

If you live in an area where winters are harsh and temperatures are often below freezing, having a high CCA rating may mean being able to start your boat on those days when it’s too cold outside for even electric motors to work properly.

Battery Warranty

When you’re looking for the best 36V trolling motor battery for your boat, it’s important to consider warranty. The length of battery warranties varies from company to company, but most warranties are between 1 and 3 years long. In addition to providing coverage for parts and labor during this period, a good warranty should also include free replacement if your battery fails within that timeframe (and some even cover damage caused by accidents).

Battery Capacity

The next thing you need to consider is battery capacity. Battery capacity (Ah) is the amount of current that can be delivered over a period of time. The higher the Ah, the longer your battery will last on one charge and vice versa. To calculate this number, take your boat’s weight and divide it by 20. For example: if your boat weighs 3,000 pounds and you want to know how many amps per hour (A/h) are needed for your trolling motor batteries then simply divide 3,000 by 20 = 150 amp hours per hour or 100 amps per hour if we were using 2 x 50 amp batteries instead of one big 100 amp battery like most people do!

  • Note: This formula works great but there are some factors that come into play such as terrain conditions so make sure you’re familiar with any potential issues before deciding which type works best for you!

How Many Batteries Should I Buy?

It depends on your boat’s size and how far you plan to go. If you have a small boat, one battery might be enough for the trip. On the other hand, if you have a larger boat or if you plan to go further than usual, then it may be worth buying multiple batteries so that they can charge while one is in use.


Hopefully, this guide has helped you understand what to look for in a trolling motor battery and how to choose one. We know it can be confusing when there are so many options out there, but we hope that we’ve given you some insight into what makes each one unique!
