No, most alternators with charge in either direction,, external fan type alternators may not cool as well when run in reverse, but you can find a bi-rotational fan.
An anti aging vitamin will not help reverse damage to the human body. Nothing can reverse the damage you have done.
Alternator Output Voltage RangeGenerally, an automotive alternator is considered to be "good" if the output voltage is in the range between 12 1/2 volts and a maximum of 16 volts.Anything below 12 1/2 volts probably will not adequately charge the battery, and voltages above 16 volts can "cook" the water out of the electrolyte, and cause damage to the battery.
"Big" Battery Damage Alternator?No, it should not damage the alternator. If this has happened it's probable that the problem is somewhere in the wiring circuit connected to the battery and alternator.
No
The battery will be Damaged. Possible damage to the Started Relay. Also check the alternator, more specifically the voltage regulator circuit which is built into the alternator.

As long as the ignition switch is off, it will not damage the alternator.
"If you connected the battery in reverse that will certainly fry the alternator and cause damage to any other polarity sensitive components as well. The alternator is NOT suposed to spark, it charges by by generating alternating current which is converted to direct current through a diode pack known as the rectifier, and the voltage is regulated by some more electronic wizardry called (amazingly enough) a regulator. Normally when alternators go wrong the charging warning light will glow, and you will get the wrong readings from your voltmeter (if your car has one)."
Yes, it will overheat.
I'm confused, do you mean when you are going in reverse or turning the engine over in reverse direction?
It's not at all uncommon. A failing alternator can easily damage a battery.
Not likely, but running the engine with a dead battery can damage some alternators. Always fully charge the battery when installing an alternator.
No. It is made to withstand water.
