How Much Amps Does An Alternator Produce. Most factory alternators are rated at 65 to 100 amps and are capable of handling your vehicles basic. But maybe its 5 amps.
Car batteries range from 40AH to 110AH and alternators range from 45 amps to 200 amps. Efficiency peaks at around 3000rpm ie 50 amps and will only give small increases over this regardless of. This is because charging at full pin would overheat the battery generate high levels of hydrogen gas and dramatically reduce the longevity of the battery.
The output of the alternator ranges from 40 Amp as much as 120 AmpFor top-amp alternator it can generate as much as 300 Amp.
Additionally how many amps does an alternator charge at. As the engine rotates the alternator pulley the rotor spins past three stationary stator windings or wire coils surrounding a fixed iron core that makes up the stator. Lets take an alternator that is capable of putting out 100 amps. 144 volts x 60 amps 864 watts.
