Attach the free end of the third wire to one of the “AC” terminals on the rectifier pack, and solder the connection. Attach the free end of the fourth wire to the other “AC” terminal on the rectifier pack. Turn the rotor shaft on the motor to charge the battery.
Can a DC power supply be used as a battery charger?
A charger that uses a DC power supply instead will usually convert the power into AC, then turn it back into DC in whatever voltage your batteries need. Determine the voltage of your power source. DC power supplies vary in voltage. The two places where you usually have to use DC power are in a car and in a boat.

Do lithium batteries need a special charger?
It is highly recommended to charge lithium batteries in series with a multi-bank charger. This means each battery is charged at the same time but completely independent of each other.
Can a 12v DC motor run on 5V?
Probably not. The motor will not have much torque, if any. Depending on the motor size the current draw will go up and is likely to be more than the charger can supply. 5Vdc is less than 1/2 the expected drive voltage of 12Vdc.
What is in a DC motor?
A DC motor consists of an stator, an armature, a rotor and a commutator with brushes. Opposite polarity between the two magnetic fields inside the motor cause it to turn. DC motors are the simplest type of motor and are used in household appliances, such as electric razors, and in electric windows in cars.
Can a completely dead battery be recharged?
While your vehicle’s alternator can keep a healthy battery charged, it was never designed to completely recharge a dead car battery. … With a seriously depleted battery, your best option is to connect it to a jump starter or a dedicated battery charger either before or immediately after a jump-start.
How do I know if my battery is charging?
Check the reading. A fully charged battery will typically display a voltmeter reading of about 12.6 to 12.8 volts. If your voltmeter is showing a voltage anywhere between 12.4 and 12.8, that means your battery is in good shape. Any voltage above 12.9 volts is a good indicator that your battery has excessive voltage.
How long does my battery last?
In ideal conditions, car batteries typically last 3-5 years. Climate, electronic demands and driving habits all play a role in the lifespan of your battery. It’s a good idea to air on the side of caution and get your battery performance tested regularly once it gets close to the 3-year mark.
