You should check your alternator output.It should be between 13.8volts and 14.2volts.If the battery is dead the alternator will charge at it's maximum rate just after idle.The output of the alternator is regulated by the voltage regulator so reving the engine won't make any difference to the charge rate.

Nope. The alternator in your engine is regulated to supply a certain amount of voltage and current to all the electrical components of your car, including your battery. Driving a car at high-RPM in a lower gear is actually bad for your engine because it generates a lot of extra heat and can break down the viscosity of your motor oil. Don't do that. You'll burn your engine up. If you're trying to charge a dead battery, driving it on the freeway for 30 minutes or so should do the trick.

nope. the peak output of the generator is about 15 to 18 v. It will take time to charge the battery...a 1hour drive will do more than a short high RPM trip

yes but i wouldn't drive it that way i would just sit with it in neutral and rev the engine. if the battery has a dead cell it wont matter because it wont hold a charge anyway.

Why are you involving the transmission? Your battery is in question. Use a volt meter and see if your getting 12+ volts. If you are, ok, if not replace.

Assuming your alternator is good and putting out full voltage, the answer is no. The Alternator should put out the same voltage regardless of speed.

no the diode in the alternator dosent care what gear you drive in..if it did fast drivers would over charge their battery...

They charge at idle. If you have a voltmeter gauge on your car observe that, it will be steady from idle to the crusing speed.

No, it could create engine trouble though.
