Howdy all,
I have a 10 amp Napa car battery charger, the circuit board of which has died. The transformer still puts out a healthy DC current at maybe 16 volts. My thinking is to simply put in (only) a hefty 12v IC regulator and use it to bring a battery up the the point (12v) where it will presumably start the car. I don't have a problem if it doesn't charge the battery to a desired higher voltage. The question is will I have to closely monitor the charging, or will the battery stop charging when it reaches 12 volts? Or..what am I missing here. I just don't want to thrown the thing out but would like to get something useful out of it without getting too elaborate with the circuitry. Thanks.
