You already know that marine batteries come in a diverse range of varieties, sizes, prices and they also come in various features, see more here. You might end up confused when you are shopping for the best marine battery. But with this article, the selection of the right battery will be easier and less problematic.

How Do You Intend To Use The Battery?

Do you intend to get a battery used for onboard devices or do you intend to get one for cranking the boat or for dual purposes? This is a very important factor you should take into account that will help you choose the ideal marine battery to suit your requirements.

Starting Suitability

The measurement of this tool is in cold cranking amps (CCA) and it is the number of amps that is discharged at 0 degrees F per 30 seconds to enable it to maintain a voltage of at least 7.2 volts. This is the minimum power required to crack an engine. If you intend to use the engine during the cold season, we suggest that you buy a battery that comes with at least 5000 CCA rating and even higher ratings.

Design And Maintenance

Some older models of these batteries require frequent maintenance but this can cause discomfort and even bore you in the process of maintaining the battery. I suggest that you purchase a new AGM  (absorbent glass mat) technology that doesn’t require any maintenance. This reduces the discomfort compared to older batteries.

Date Of Manufacture

Even a battery that is coming directly from the store can lose its effectiveness and its battery hold. If you do a comparative analysis of a battery coming directly from the factory to the one that has stayed in the store for one year, you will come into the realization that they have a different level of performance. In view of this, always peruse the battery for the date of manufacture to enable you to get the one that offers the best performance.

Size

Marine batteries come in different sizes and they are grouped into several varieties. For example, you can get 27, 6D, 24, 31 and a host of others. If you intend to replace your old battery, ensure that you opt for the one that fits into the old box. Another factor that you should consider is the ventilation of your boat to avoid ending up with a large battery that occupies much space.

Types

The batteries are available in different types depending on your requirements. For instance, starting batteries deliver short high amperage to run the starter. These batteries only need to be charged for a short time. Asides this, another variety is the deep cycle batteries that can withstand deep discharges. These set of batteries can tolerate a series of discharges and recharges before you dispose of them.

Technology

Marine batteries feature several types of technologies. One of them is the flooded-electrolyte batteries that offer a moderate performance and they come at a low price rate. These batteries have the capability to discharge themselves and they require frequent maintenance by ensuring that they electrolyte are filled to the required level. You can also decide to opt for absorbed glass mat batteries that feature fiberglass coils immersed in electrolyte liquid to prevent spilling acid. These batteries offer a slow self-discharge rate and have more power capacity.
