Best Marine Battery Reviews – A Buying Guide

The true fact is that it is quite difficult to purchase a boat battery because there are numerous factors to consider. You will want to acquire the best boat battery that is worth the money from and will also consider your budget. In short, you won’t like to spend a huge amount of money.

There are numerous varieties of batteries ranging from starter, deep cycle or a combination of the two popularly referred as dual purpose. However, the selection of this product depends on your intended usage of the battery. Listed below are the several factors that you should take into consideration.

Intended Purpose

The boat/marine batteries may be used for two main purposes which include: generation of power to the vessel for the duration of use or for traveling purpose, igniting an engine to start operation.

These batteries can effectively discharge power of several voltages and ratings, a fact that greatly determines the type of usage that they may be utilized for. Follow this rule, if you intend to use the batteries for cranking only, then I suggest that you opt for the low rating type.

However, if you intend to use it to carry out the two major operations i.e powering and cranking the vessels, then I suggest that you opt for a dual purpose battery or deep cycle with higher rating/capacity.

Cold Cranking Amps

The full meaning of the acronym CCA is termed as Cold Cranking Amps (or Marine Cranking Amps utilized mainly for marine batteries) this measures the capability of an acid battery to generate plenty of power within a short period of time.

This will show the capacity of the electrical power to be generated by the battery’s lead-acid within the duration of 30-second, and at a temperature rate of zero degrees Fahrenheit, and afterward, the voltage will drop to around 7.2 Volts threshold. Note that the minimum power of electrical energy that is required to crank an engine is 7.2 Volts.

If you are using the boat in an extremely cold region, I suggest that you use a battery that comes with an MCA rating of at least 500.

Reserve Capacity Rating

Reserve capacity measures the total length of time that will take a  fully-charged battery to deliver 25 amperes of electrical current in an area with a temperature of 80°F and below, before being applied to 10.5 volts devices.

For instance, a battery that has a reserve capacity level of 150 minutes can effectively last for last for the same period of time while discharging 25 Amperes of load. However, it is better to opt for a battery with higher reserve capacity compared to the ones with low capacity for maximum performance and utilization.

Amp Hour Rating

This rating is mainly utilized for the variety of trolling battery. It measures the number of amperes that the battery will deliver in a space of 20 hours. For instance, for a battery with 100 ampere-hour rating, theoretically, it will deliver 5 Amperes of electrical current in one hour and will last for 20 hours, provided that all factors are constant.

However, some electrical current is lost due to the battery’s internal resistance, there might be cases whereby the battery won’t be able to deliver the maximum electrical current as stipulated in the rating.
