Any car charger will do. I recommend that you use a trickle charger rather than a jump charger. Also, look into a Battery Tender which will not only charge your battery at a proper pace, but you can leave it plugged in an the Battery Tender will maintain your battery for you so that it never becomes low again.
Very gently. A motorcycle battery can't take as much charging current as a car battery, so you need to use the lowest setting on your charger.
Any good 12 volt battery charger that puts out around 10 amps. Make sure it is an automatic charger. The same charger you use on an auto battery can be used on a motorcycle battery.
Once the engine is running it mechanically turns an alternator. The alternator generates a current which powers the motorcycle and also recharges the battery.When removed from the motorcycle the battery will need to be recharged using a specialist battery charger which plugs into household mains.
In 24 hours it will be charged enough to start the car. You really need a much larger charger for a car battery.
If it is an automatic charger let it charge until the charger shuts off.
You need a 6 volt charger. When you buy a charger look for one that monitors the voltage level of the battery while it is charging and when the battery is fully charged it will turn off. Indiscriminate charging of a small battery can easily destroy it. Being left on the charger too long can boil the electrolyte out of the battery. A battery can not recover from this action and it will need to be replaced.
I doubt the charger is putting out 30 Amps on a slow charge. need more info on battery and charger.
No, you need a 24 volt charger.
A .6 amp charger is a trickle charger. It would take days to charge a dead 12 volt battery with this charger. You need a 10 amp charger which will charge it in a couple of hours.
Yes, you need to use a trickle charger or a very small charger such as one smaller than 5 amps.
Unless it is a rechargeable battery you cannot charge a dry charge battery. If it is rechargeable you need to purchase a charger for that size battery. Automobile batteries are not dry charge.
you need a battery charger.
