Yes. It is done all the time in automotive electrical systems. The alternator, which creates AC, has its current rectified using diodes.

How you charged the 12 volt battery?
Charge it with a 12 volt battery charger.
Can you use a 12 volt battery to charge a 48 volt battery?
No
Can you charge a 6 volt battery with a 12 volt battery charger on slow 2amp charge?
No.
Can a 12 volt charger charge a 8volt battery?
No, a 12 volt charger will overcharge a 8 volt battery and destroy it.
Can a 12 volt battery charger be used to charge a 24 volt battery?
no it can't
Can you use a 6 volt battery charger to charge a 12 volt battery?
No it will not work
Why would the battery in a VW Jetta not be getting any charge if it has been replaced but you still have the same problem?
You need to check if the ALTERNATOR is giving the correct output so as to charge the battery. By having a volt meter across the batery terminals one can then rev the engine and the voltage accross the battery should be about 13.8 volt indicating that the Alternator is charging the battery. If this 12 volt bateery voltage does not increase, this indicates a charging problem (mostly with the alternator either the brushes or one of the diodes in the alternator).
Can the wrong size car battery damage the alternator?
No, not unless you installed a 6 volt battery instead of a 12 volt battery.
Will a 120 volt AC to 12 volt AC adapter charge a 12 volt car battery?
No, the battery is DC not AC.
How do you equalize a 6 volt marine battery with a 12 volt charger?
If you are asking the question, can you charge a 6 volt battery with a 12 volt charger, the answer is no.
Can you charge a 28 volt Gill aircraft battery with a 12 volt car charger?
No, the battery charger has to match the voltage of the battery it is to charge.
Can you connect a 12 volt auto alternator to a 24 volt system to charge the batteries?
If you connect an alternator that has been designed for charging a 12 volt battery to any 24 volt system in an attempt to charge its batteries, that alternator will not work because of either of two different reasons:if the 24 volt battery is completely dead or flat the 12 volt alternator will not be able to charge it to much above 18 volts. That is about as much practical use as having a flat 24 volt battery!if the 24 volt battery is not "flat" but has a voltage that is in its normal range - between about 23 volts and 27 volts - the 12 volt alternator would not do anything because its output voltage cannot go high enough.Some more facts:12 volt systemsAn alternator designed to charge a nominal 24 volt battery will have a voltage and current regulation system to control its output voltage between about 13.5 and 18 volts and an output current that could vary between zero and about 40 or 50 amps.The overall range of current amperage output from the alternator would vary from vehicle to vehicle depending on the sizes of the alternator and battery and those in turn would be sized to match the likely normal current amperages drawn by the vehicle's ignition, night-time road lighting, air conditioning and other systems.The actual charging voltage and current being output from the alternator at any instant depends on the "state of charge" of the 12 volt car battery. A nominal 12 volt lead-acid type car battery that is flat has a voltage of about 11.5 volts or less. One that is fully charged would have a voltage of about 13.5 volts.24 volt systemsAn alternator designed to charge a nominal 24 volt battery will have a voltage and current regulation system to control its output voltage between about 27 and 36 volts and an output current that could vary between zero and about maybe 80 or 100 amps.The overall range of current amperage output from the alternator would vary from vehicle to vehicle depending on the sizes of its alternator and battery and those in turn would be sized to match the likely normal current amperages drawn by the vehicle's ignition, night-time road lighting, air conditioning and other systems.The actual charging voltage and current being output from the alternator at any instant depends on the "state of charge" of the 24 volt vehicle battery. A nominal 24 volt lead-acid type battery that is flat has a voltage of about 23 volts or less. One that is fully charged would have a voltage of about 27 volts.Only in the instance where two 12 volt batteries were connected in series to produce power for a 24 volt system, could a method be devised to use a 12 volt alternator to charge the batteries independently.
