Can a car alternator charge a deep cycle battery?

Yes it can but it is better to bring the engine speed up to 1500 rpm or so. The alternator will be able to charge the battery at a higher rate because it is turning faster. At idle speed 500–700 rpm the alternator wont produce much charging capacity.

Can alternator charge deep cycle?

Will a high output alternator damage a deep cycle battery?

The answer is probably “not a good idea” for several reasons. Car Alternators are not designed for high current output–they will fall back and/or not last long with heavy loads. You would have to look at a truck or marine alternator designed for charging large battery banks and retrofit to your car.

Can you jumpstart a car with a deep cycle battery?

Yes it will jump start a deep cycle battery just as easily as any other 12 volt battery. … Deep cycle batteries are made to be discharged a lot more than car batteries and still charge back up to full without damage.

How fast does an alternator charge a deep cycle battery?

If the car has a 100 amp alternator it would probably put out maybe 10 amp at idle speed, so a 50% discharged 100 amp hour (you should avoid a lower depth of discharge) battery would take at least 5 or 6 to fully charge. At highway speed more like a little over one hour.

What amp should I charge my deep cycle battery?

It is better to charge a deep cycle battery at a higher charge rate like 6-amps, 10-amps or higher. However, check you battery specifications for the proper charge rate.

How long does it take to charge a deep cycle battery while driving?

Normally, a deep cycle battery often holds 48 amps so if you charge it at 1 amp, it will take you 48 hours. Similarly, if you charge your car battery at 4 amps, the total time to make the battery fully charged is about 12 hours. Therefore, if you need a quick charger, a 4 amp charger is not a good option for you.
