Looking for the best marine battery on the market is quite different from a car battery hunt — they inherently have very different benefits and design features. Understanding things like CCA vs MCA is key if you want to find the right battery for your boat or RV. Advance Auto Parts' recommendation is a DieHard Marine Battery, so read on to find out more about why it has the performance level and reliability you need for all your boating adventures.
THE DIFFERENCE BETWEEN A CAR AND MARINE BATTERY
So how does a marine battery differ from conventional car batteries? The latter cranks up the engine, after which they more or less sit in the car and benefit from the alternator (aside from minor power supply tasks like running the A/C or sound system). A marine battery has to behave very differently. Not only does it need to offer high cranking amps to start up your boat's engine, but it also has to have significantly slower discharge power. This is to successfully supply energy for lights, sound systems and any important equipment required to ensure the safety of the crew.
WHAT TO LOOK FOR IN MARINE BATTERIES
When looking for the best marine battery, you have to consider three essential factors. The first and most important is the marine cranking amp (MCA) rating, which is essentially the same as the CCA rating in cars except that it's tested at a temperature of 32 F. This is to ensure your boat will perform well in cold temperatures. Two other factors are reserve capacity (RC) and the amp hour (Ah) rating, which measures the current drained from the battery at 80 F degrees while sustaining a voltage of 10.5V for a period of 20 hours. Always make sure to get at least what the manufacturer recommends when it comes to these ratings — if you want to go for an even better battery, search according to what your budget allows.
THE BEST BOAT BATTERY OUT THERE
The DieHard Marine Gel battery is currently considered the best marine battery on the market. Like all DieHard deep cycle batteries, it is designed to meet the high energy demands of a boat and is capable of powering all GPS systems, radios, trolling motors and lighting systems. The battery also has a faster recharge rate than most of its competitors, which makes it a much safer choice for frequent boat rides.

WHY CHOOSE THE DIEHARD MARINE GEL BATTERY?
The DieHard battery is rated at an impressive 780 CA, and its MCA rating is very close. It was also rated at 550 CCA, which means you can even take your boat out in freezing weather. Unlike most marine and RV batteries, it is designed specifically for boats, and its RC rating of 180 is superior when compared to most deep cycle batteries. If you ask most experts, they can tell you the DieHard Marine Gel battery is the best marine battery for many possible uses, as well as a highly reliable model that won't let you down when faced with trying conditions.
