Yes and no. If you use a jumping unit, most have a setting that should match your cycle's battery voltage and limit current. You can jump one cycle's battery with another cycle's battery provided they are the same voltage and a rechargable-friendly (for example lead-acid) chemistry.
Yes as long as it is the right voltage: a 6v battery needs a 6v charger; a 12v battery needs a 12v charger. <><><> If you can set the battery charger's output to give either a 6 or a 12 volt output, then you must always remember to set it to 6 volts if you want to use it to charge a 6 volt motorcycle car battery.
In 24 hours it will be charged enough to start the car. You really need a much larger charger for a car battery.
Depends on the amperage of the charger. A 10 amp charger will charge it in about 1 hour.
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 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.
A trickle charger is a car battery charger that is designed to be left on a car for very long periods of time to re-charge that car battery by slowly adding charge to the battery.
Chargers don't care is the battery is used on a boat, a car, or whatever. What is important is that you match the voltage of the battery and the charger. Don't use a 12volt charger on a 24volt battery, etc.
Not on any modern car with a 12 volt system.
sure, you can buy a battery charger that will charge any car battery.
No
A battery booster is a portable battery, fitted with cables and a charger, which is used to charge a dead battery, especially in a car.
Yes, the car can be started with the battery charger attached to the battery as a boost.I been doing that for years.
