Marine Batteries Buyer’s Guide

There’s a lot of technical terms being thrown around in these reviews, so it may benefit you to brush up on some of the features to look for when purchasing the best marine battery for your needs. Here’s a quick breakdown of some terms you’ll often see and how they relate to your marine battery experience.

Purpose: There are three types of marine batteries: starting batteries, deep cycle batteries, and dual-purpose batteries. The starting one are solely designed to crank the starter so your engine can turn over. The deep cycle batteries are designed to power your electrical components, which mean they are designed to last longer. The dual-purpose batteries are the best of both worlds, as they combine both the starting battery features and the deep cycle battery features.

Reserve Capacity: The reserve capacity rating is how long a battery can sustain a load of 25-amps before dropping down to 10.5-volts. Some batteries are more universal and don’t have reserve capacity ratings. These batteries are better used with solar panels, small trolling motors, etc.

Cold Cranking Amps: The cold cranking amps is the amount of amps a battery can provide in a 30 second period, while maintaining a minimum voltage of 7.2-volts.

Weight: Weight is a good feature to pay attention to, especially if you want to use your battery for a trolling motor on an inflatable boat, because you will have to haul the battery around.

Keep these terms in mind when comparing prices and features to find the Best Marine Battery!
