In the right corner it's....Sir Gawain! He is nephew to King Arthur, and an honorable knight of Arthur's Round Table. He is very popular with the ladies, and quite charming. He is loyal to his king and queen and keeps his promises.
To charge the battery, the alternator voltage output has to exceed a minimum charging voltage. This minimum charging voltage is 13.8 volts dc across the battery terminals, or at the output of the alternator. A single lead-acid cell starts to charge at anything over 2.25 volts.ince a 12 volt battery has six cells, any 12 volt lead-acid battery needs at least 13.8 volts to start to charge. This voltage will be enough to fully charge or maintain the battery on a trickle charge, but charging time will be very long at 13.8 volts.
It can be brought back to life by recharging it with a battery charger, or by running the engine so that the alternator can charge it. For more information on the battery, Click Here. .The main component in the charging system is the ALTERNATOR.The alternator is a generator that produces Alternating Current (AC), similar to the electrical current in your home. This current is immediately converted to Direct Current (DC) inside the alternator.his is because all modern automobiles have a 12 volt, DC electrical system. A VOLTAGE REGULATOR regulates the charging voltage that the alternator produces, keeping it between 13.5 and 14.5 volts to protect the electrical components throughout the vehicle.
