Does my Mercury outboard charge my battery?

Does my Mercury outboard charge my battery?

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.

How do I know if my outboard motor is charging my battery?

Put the multi-meter on Volts scale and look for 13.5 to 14.5v DC as indication it’s charging. Anything around 12.8v or less means it’s not getting charge. If it is below 12v with the engines off it may take a bit to climb above 12.8, but if it’s climbing with the engines on, it’s charging.

What part charges the battery on an outboard motor?

alternator
Once the outboard is running, its alternator will recharge the cranking battery to compensate for the power delivered while starting the motor, and for any power drawn for other “house” needs, including live well or bilge pumps, fish finders, or navigation lights.

How do I know if my outboard has an alternator?

The most certain way to find this out is to place a voltmeter on your battery terminals while the outboard is running at about mid-throttle or high idle speed. If the voltage you measure is above 13 volts, you have an alternator and it is working.

How do I know if my boat alternator is charging my battery?

If you have a voltmeter, with the motor running, put the leads across the battery terminals and rev the engine to 2000 rpm and check the voltage. Again it should be between 13 and 15 volts DC. If it is, then charging system is working correctly.

Does a boat battery charge itself?

Yes, they charge. Most outboards with an electric start will re-charge the battery as they run. Deep cycle batteries can be used for things like pumps.

Do outboard boat motors charge batteries?

How do I keep my boat battery charged?

HOW TO TO KEEP MARINE BATTERIES CHARGED UP

  2. Avoid high voltage fast charging cycles – Stick to recommended voltage requirements and unplug immediately after the charge is complete OR see the next tip.

How long does it take for an outboard to charge a battery?

around 4-6 hours
In most cases, a marine battery will take around 4-6 hours to charge. This will bring your battery from 0% charged to 80% charged. In addition, it depends on the type of charger that you’re using. Some chargers are more efficient than others, which means that it’s important to pick out a high-quality charger.

Do I need to disconnect my boat battery to charge it?

No need to disconnect the batteries. If you have a battery switch, turn it off, if not, don’t worry about it. A word of caution, if you run the battery down playing music or with lights for hours, the charging system on the boat will not bring the battery back up sufficiently in a short boat ride.

How often do I need to charge my boat batteries?

Fully charge them about once a month over the winter and they will be ready when you are in the spring. Try to keep them off of concrete floors if possible and cover the terminals to help prevent discharge. The last thing you want is a dead battery on the launch ramp on opening day, or a dead trolling motor battery.

How often should I charge my boat battery?

Any type of lead acid battery should always be left in a fully charged condition. Having done that, you should either charge your battery every 30 days or so, or consider getting a smart battery charger to maintain your battery all the time.

Should you run your boat on both batteries?

NEVER use the “BOTH” position except to parallel both batteries if they’re both flat, almost like an attempt to “jump-start” your own engine. And don’t forget to pay attention to the warning, which says, “Stop engines before switching ‘OFF'”.
