What is the difference between a regular car battery and a marine battery?

Car batteries are designed to deliver concentrated bursts of power to crank over and start the engine. Marine batteries must not only have the starting power to crank over high compression engines but also provide the reserve capacity needed to run on board accessories.

Are boat batteries the same as car batteries?

Car batteries, which fall into a class known as starter batteries, consist of lots of thinner plates. Marine batteries are made up of a combination of these same thinner plates, as well as thicker, heavier plates that are traditionally found in what are known as deep cycle batteries.

Do I really need a marine battery?

Not only are marine batteries expected to crank over an engine, they are also required to supply energy for lighting, pumps, sound systems and anything else that might be essential for comfort or safety while out on the water. Anyone that has spent time in rough water will appreciate shock resistance in a boat.

Do boats need special batteries?

Many boats will need two types of batteries, an engine starting battery and a deep cycle battery for powering navigation, lights and domestic equipment. Dual types are manufactured, but are usually only suited for small powerboats or sailboats.

Can I use marine battery in my car?

If the marine battery is a 12-volt battery, then you can use it for your car. This will enable it to be both a starter and a deep cycle battery. Marine batteries are probably not recommended to power cars for a long period of time. This is because they would probably shorten the battery’s lifespan.

How many cold cranking amps do I need?

The standard recommendation is a battery with at least one Cold Cranking Amp (CCA) for every cubic inch of engine displacement (two for diesels). CCA rating is an indication of a battery’s ability to deliver a sustained amp output at a specified temperature.

How many cranking amps do I need for my boat?

Starting batteries need to deliver large amounts of current (often between 75 to 400 Amperes ) to start your boat’s engine. They can only provide this huge amount of current for a short time (less than 15 seconds). Using your starting battery for longer than this can cause irreversible damage to the battery.

What is the difference between marine cranking amps and regular cranking amps?

Cold Cranking Amps (CCA) is a test conducted at 0 F (-18 C) for 30 seconds without falling below 7.2v at the battery’s CCA rating. Marine Cranking Amps (MCA) is a test conducted at 32 F (0 C) for 30 seconds without falling below 7.2v at the battery’s MCA rating.

What is special about a marine battery?

Marine units feature thicker internal lead plates than their automotive counterparts, which allow them to discharge energy over a longer period of time. Finally, you can identify a marine battery by its use of “marine cranking amps,” or MCA rating, instead of the standard automotive “cold cranking amps” (CCA).

Can you jump start a boat?

All you need is a set of jumper cables and a functional battery, OR it could become very handy if you have a jump starter. Jump-Start your boat with a battery from another boat or car directly. Take the battery out of the boat and use it after fully charging it. Use a Jump Starter to start your boat.

What size battery should I put in my boat?

Most boaters will use 12-volt lead-acid batteries in their boats. If your boat uses 6-volt, 8-volt or some other type of battery that isn’t 12-volt, you can still read the next few paragraphs, but know that OPTIMA doesn’t offer replacements in those voltages for your boats.

Is a marine battery 12v?

A typical 12-volt lead-acid battery must be taken to approximately 14.2-14.4 VDC before it is fully charged. Once fully charged, marine batteries should be held at a considerably lower voltage to maintain their charge – typically 13.2 to 13.4 volts.

How often should I charge my boat battery?

In the marine environment, it is more likely to be done every 20–50 cycles to extend the life and capacity of wet batteries. Gel and AGM batteries should not be equalized. Since electrical equipment and light bulbs can be damaged by high voltage, the battery should be disconnected from all loads during equalization.

Can a boat battery get wet?

Continual exposure to freshwater will break down the battery with rust and slow, discharge rates. If you notice that the battery is submerged in freshwater, you should react in the same way as saltwater. Dry the housing and terminals. Marine batteries will always be negatively impacted by any type of water.

How long should a boat battery last?

The average life of a boat battery is around 3-4 years, although they can last up to 6 years in the right conditions. To ensure your battery lasts its full lifespan, keep your batteries connected to a maintenance charger to keep it fully charged.
