Buying guide for Deep Cycle Marine Batteries 2020

There are many different Deep Cycle Marine Batteries on the market from well known to lesser-known brands. The buying process can be a minefield if you don’t know what to look out for. We have taken this into account to bring you a thorough guide that will help you in choosing the right battery for your needs.

 

What is a Deep Cycle Marine Battery?

 

A deep cycle marine battery differs from your normal run of the mil batteries. They provide you with sustained energy over a long period. These batteries are meant to run until its 80% discharged when it reaches this point you will have to recharge it. However, most manufacturers will recommend you only discharge the battery to a max of 55% and this will aid in the longevity of the battery.

You will find that the ‘level of discharge’ is known as the “deep cycle” which is contrary to other batteries who only gives short discharges and needs to be charged again. It should be noted that a starter battery operates with small discharges and to be more specific normally 2-5% discharges each time it is used.

 

What are the benefits of investing in a Deep Cycle Marine Battery?

 

  • Deep Cycle Marine Batteries can supply power to appliances and electronics
  • The batteries have a long lifespan
  • The Deep Cycle Marine Batteries can be used in a wide range of applications
  • They have solid lead plates
  • There is a very low risk of the marine batteries overheating
  • These batteries can be discharged down to 80% without negatively affecting the battery

 

What types of Deep Cycle Marine Batteries are there?

 

There are different types of batteries that you should consider for various applications. You will get Starter/cranking batteries and dual-purpose batteries each with their advantages and disadvantages. This is a short overview of what each battery does.

 

Cranking/Starting Marine Batteries

A starting battery or cranking battery can be defined as a battery that allows the marine vessel to start. It does this by sending power to the engine when the ignition is turned on. What’s more strong and short bursts of energy are needed that are sent to the battery.

 

Dual Purpose Marine Batteries

A dual-purpose battery can do the job of a starter battery while also being able to contribute to other applications that you need running. They have thick plates inside of them that increase power and longevity.

 

 

Final thoughts on Deep Cycle Marine Batteries 

 

There are various Deep Cycle Marine Batteries out there to choose from and we hope that our guide has made the buying process a little easier. We found that a marine battery can be used in a variety of applications that are beneficial to your everyday and recreational life. They also come in dual and starter batteries that each has its disadvantages and advantages. We recommended a dual battery because it can be used for a wider range of applications. However, the choice should solely rely on how you will use the battery in your everyday life. This concludes our Deep Cycle Marine Battery review of 2020.
