Yes. Almost all outboards that have electric start and that were built in the last 20 years, will have either an alternator or a stater that charges the battery when the engine is running. At what capacities and loads they charge the batteries is another thing.

How many cranking amps do I need for my boat?

This deep-cycle marine/RV battery is rated for 500 MCA (marine cranking amps) and 80 amp-hours. The 140-minute reserve capacity indicates the number of minutes a battery can deliver 25 amps of current without dropping below 10.5 volts.

Will a boat battery charge while idling?

The battery of a boat does get charged while idling, but it isn’t a lot until you either rev up the engine or take the boat out and start running it at normal speeds. The output current needed for a recharge highly depends on the rotational speed of the alternator.

How many batteries do I need in my boat?

Boats under 14 feet will only require one battery. Boats 15-23 feet, with a single-engine, will only require two batteries unless they have a trolling motor, which can require up to three more batteries.

Deep cycle batteries can be entirely drained and recharged many times over, cranking batteries can’t.

Is higher cranking amps better?

And the higher the cold cranking amp rating of the battery, the better it is for your car. … Cold, cranking amps are rated at 0, and the higher the temperature when they’re doing the rating, the higher the numbers. So, that CA rating may look impressive, but it really isn’t.

What is a good CCA for a battery?

Typical CCA readings for a car range from 350 to 600A, and higher for trucks. SAE J537 specifies that a battery with a CCA reading of 500A can deliver 500A at –18°C (0°F) for 30 seconds without dropping below 7.2 volts.

When should I replace my boat battery?

Generally, batteries will last from 2-5 years when properly maintained. If you have any questions about charging, caring for or replacing your battery(s), please call Chris in our Service Department at (508) 563-7136, or by email at chrisg@kingmanyachtcenter.com.

What kind of battery do I need for my boat?

Basic Boat Battery Types There are two basic types of 12-volt batteries: 1) cranking, or starting, batteries, which are designed to start your main engine, and 2) deep-cycle batteries, which are used to power electrical accessories such as trolling motors, fish-finders and radios.

Can you jump start a car with a marine battery?

Yes you can, most marine deep cycle batteries are also marine starting batteries (look for CCA rating on top of battery) so jump starting should be no issue at all. … If my alternator is broken and I jump start my car, how long should I leave the cables connected to charge the battery?

Can a deep cycle battery start a boat?

Is it OK to use a higher CCA battery?

As long as it physically fits in the battery tray and hold-down, there will be no problem. Your new battery simply has more cranking capacity than your original. A good thing on cold mornings!
