Best Answer

you would have to put some type of resistor in the circuit with the motor...the resistor would have to be in series with the motor and would have to be of a high enough value to lower the voltage by 9 volts....There is a formula for working this out but you would need the amperage of the motor to figure this....

Can a 12 volt motor turn a mini alternator to charge a 12 volt battery that runs a car stereo?

If you can get the battery to run the motor, write it up in a science journal. You'll be rich. Sure but what are you going to use to power the 12 volt motor? You will have to use another battery which you could just use to power the radio in the first place.

Yes, it has twice the voltage power.


How many hours a 850amps battery can run a 2000 watts motor?

It depends on the battery's voltage. Such a battery's capacity is given in ampere-hours, not amperes. An 850 amp-hour 12 volt battery can theoretically operate a 12 volt motor for about 12 minutes but in practice it's probably, maybe a lot less, since the motor will probably stop as the battery nears its depletion.
