Can a car alternator charge a deep cycle marine starting battery?

Question

I want to make an alternator wind mill to charge a battery but will a deep cycle marine starting battery charge properly with a standard car alternator? I am using the battery on an electric moped and wanted to charge the battery without having to cost my parents alot on the electric bill.

Answer 1

If you are using the regulator that comes with the alternator, I think it will be ok, as long as the marine battery is about the same rating as the car battery was.

I'd keep an eye on it until I was sure it was OK.

Answer 2

They're not much different than the alternator on the outboard or inboard motor, so yes, it'll work.

  But the cost of running a regular deep cycle battery charger is really not that expensive, so the alternative is not worth the cost of manufacture or effort.
