Best Marine Starting Battery Reviews

Marine batteries use high starting amps which is short bursts of high power to start the engine. Good marine batteries have high starting amps to have the motor started and can run continuously for many hours just like a deep cycle battery does. The reserve capacity rating of good marine batteries is higher than normal ones. They also come with a higher cold starting amp rating. Another vital statistic is the pulse starting amp rating which measures the starting amperage with the engine.

Buying Guide for Best Marine Starting Battery

Whether a battery is right for you or not dependents on the usage of the battery. Below is a list of factors that you should consider.

 

Intended Purpose

The marine batteries may be used for two broad purposes: starting an engine, and powering the vessel throughout its journey. If you intend to use the battery for starting only, go for the one with a low rating capacity, but if you intend to use it for both starting and powering your boat, then a deep cycle or dual purpose battery with higher current capacity is best for you.

 

Cold Starting Amps

Cold Starting Amps or Marine Starting Amps is a measure of the ability of an acid battery to support plenty of power within a short duration of time. It shows how much of electrical power the lead-acid of a battery can generate within a 30-second duration, at zero degrees Fahrenheit temperature, before the voltage ultimately drops to below the 7.2 Volts threshold which is the minimum power needed to crank an engine.

 

Reserve Capacity Rating

Reserve capacity is the total duration that a fully-charged battery works. For example, a battery 150 minutes of reserve capacity rating can last for two and a half hours while discharging a load of 25 Amperes. The battery with the higher reserve capacity is preferable for optimal performance.

 

Amp Hour Rating

It is a measure of the number of amperes that a battery produces in a duration of 20 hours. For instance, a battery with a 100 ampere-hour rating can provide 5 Amperes of electrical current per hour for a total duration of 20 hours, providing that other factors are constant. However, some electrical current is usually lost by reason of the battery’s internal resistance. So it is strongly recommended that a higher rating than the one desired is to be generally selected.

 

Charging of the Battery

The electric appliances on boats draw current from the deep cycle battery, and it needs to be charged regularly to prevent damage to the battery. There are many methods of charging the battery from onboard chargers to portable alternatives.

 

Price and Warranty

Consider the cost of the battery and the accompanying warranty before you make the final decision. Choose one that balances between the two so that you can get the best service within your budget.

 

Versatility

Choose a battery that you can use for both starting the motor and powering onboard devices. That means it will work both as a starter and a deep cycle battery.

 

Weight

Choose a battery that is light and portable weighing somewhere between 20 pounds (9.1 kg) and 50 pounds (22.7 kg).

 

Vibration Resistance and Durability

As choppy waters create jarring vibrations, choose a battery that can withstand these vibrations easily. Spill-proof and shock-resistance boost durability as well.

 

Voltage Rating

The voltage rating of a boat battery decides the amount of power it generates. So a 24 Volt battery is preferable as it generates plenty of power and reliable as well.

 

Final Verdict

People often overlook the necessity of having a suitable marine starting battery for their boats, and they have the wrong impression that any battery will do the job well. They can only understand how wrong they were once they get stuck in the middle of the water. So be wise enough to buy the best marine starter battery for a wonderful cruising experience.
