A Guide to Choosing a Kayak Battery

There are different types of batteries, for example, the car battery or the duracells. But did you know that there is more to batteries? You might not want to understand the chemist behind their operation, but you should learn about their differences. If you love kayaking and it is time to buy a battery for your kayak, and there are some things you should know as discussed below. Read on.

Size and Weight

If you have a powerboat, you are not supposed to worry about the size or weight of the batteries. Some powerboats run with three 12v batteries, one to start the outboard, move the fish finder and troll the motor. Have it in mind that a kayak battery weighs between 50 to 75 pounds. Before buying any battery take a close look at the kayaks maximum capacity and space. The added weight should not affect the kayak in any negative way. If you are not running a trolling motor, you can use an external power bank instead.

Battery Life

As much it might sound hard and complicated it is best for you to understand the power of the batteries. Battery power is measured in amp-hours. You will either see the abbreviations Ah or mAh(for smaller batteries) on the battery descriptions. It is essential to look at how many Watts your battery draws at. If it becomes too difficult for you, you can use online calculators or ask the salesperson to help understand the power and battery life as per the descriptions, a deep cycle battery can keep you going for hours.


A battery is not supposed to be too hot or too cold. Extreme temperatures affect their functionality. If you have ever tried to start a car when it is freezing, you are aware of this, but what many people do not know is that high temperatures are not good as well.


The battery should be stored in a cool and dry place when it is not in use. Also, make sure that it is charged and not depleted when in the store. Before you put it on that store, ensure to top it off.


There are some batteries whose pack plug into the outlet, but most of the time you will need to invest in a new battery charger. Always go for batteries which take long to recharge. Fast rechargers will fill fast, and many times you will end up overcharging. A standard battery will recharge overnight with the smaller ones recharging in hours.
