Facts to Consider Before Buying a Marine Trolling Battery

 You will need a specially designed battery for your trolling boat that can withstand the pounding and vibration common aboard a powerboat. It should also be robust and capable of standing up to extreme temperatures while on the water. The marine trolling battery should be able to meet all these criteria. Its price tag may be heftier than a car battery’s, but it is still the best choice for marine and trolling applications if you want something that will be more reliable and last longer. 

If you are looking for a good and reasonably priced marine trolling battery, be sure to mind these facts to help you make an informed decision: 

Types of marine batteries 

There are different kinds of marine batteries, but not all of them are suitable for trolling. The basic types are starting, deep cycle, and dual-purpose. Here is a quick overview of each: 

• Starting batteries – They offer quick and powerful energy spurts over short periods, as they are meant to start the engine while being rapidly recharged by an engine alternator. Thus, they are not ideal for powering appliances or trolling motors. 

• Deep cycle battery – A good marine trolling battery that discharges slowly over longer periods and can withstand several discharging and charging cycles. 

• Dual purpose batteries – With the combined performance of deep cycle and starting batteries, it is ideal for smaller boats without room for two batteries. 

You are also likely to come across battery types like lithium, AGM, and lead-acid. Among those three, lithium batteries are far superior for trolling applications, given their performance, longevity, reliability, and safety. They do not require maintenance, too. 

Amperage hour rating 

This is an important factor before you buy a marine trolling battery. Consider a battery with at least a 100-amperage hour rating. 

Battery features 

Consider high-quality batteries that are built following ISO9001 and UN38.3 standards. A LiFePO4 (lithium iron phosphate) battery is non-explosive and safe, and it comes with its battery management system. Some manufacturers have designed their lithium marine trolling battery to have a built-in LED charge indicator to end your second-guessing.
