sure, you can buy a battery charger that will charge any car battery.
No, the battery charger has to match the voltage of the battery it is to charge.
If it is an automatic charger let it charge until the charger shuts off.

No, you can charge the battery while it's in the car.

No
Use a battery charger.
Not with out being attached to a battery charger. On a 10 amp charger in 8 hours it will charge enough to start the car, allowing the battery is god enough to charge
