How Do You Intend To Use The Battery?
Do you want a battery for running onboard appliances or do you want one for cranking the boat or both purposes? This is a crucial factor you should put in mind that will help you select the right marine battery to suit your needs.
This is measured in cold cranking amps (CCA) which is the number of amps that is delivered at 0 degrees F in 30 seconds so that it can maintain the voltage over 7.2 volts which is the least power for cracking an engine. If you intend to start your engine on a cold season, you should purchase a battery that has at least 5000 CCA rating or even more.
Design And Maintenance
Some older batteries require maintenance, and this can bore you if you have such a battery. You can think of buying new AGM (absorbent glass mat) technology that doesn't need any maintenance. This makes them very easy to own as compared to older batteries.
Date Of Manufacture
Even if a battery is new and unused, it can lose its effectiveness and fail to maintain charge. If you compare the performance of a battery that has stayed one year to the one from the factory, you will notice a very big difference when it comes to the performance.
