Unless it's an old vw bug, cars usually run on a 12 volt dc system nowadays.
Motorcycles often run on a 6 volt dc system.
Different systems require different charging voltages so you won't ever be able to charge a 12 volt car battery from a 6 volt motorcycle battery charger as the output voltage would be way too low.
However, 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 12 volts if you want to use it to charge a 12 volt car battery.
Battery chargers generally operate at the same voltage as the voltage as the battery they are charging. They usually vary the amperage they feed into the battery to recharge it. A trickle charger usually only feeds a few amps into a battery to recharge it slowly over time. A fast charger feeds more amps for less time to bring the battery to full charge faster. Automotive alternators are the only charging systems that I am familiar with that generate more voltage than the battery they are charging. That's because they have to run the car AND recharge the battery at the same time. Car alternators can vary their amperage and voltage outputs to allow for the varying demands of the car and all of it's electrical devices and recharge the battery as needed.
A: If you means for a car it would be 13,68 volts minimum. But what is really important is the amperes out of it that is what is needed to charge a battery and that can be as high as 100 200 amperes out of the generator. Once the car has started the battery is no longer necessary to run it the generator and the regulator will just do fine.
As long as the charger is connected to its power source it will take a small amount of power from that source (even if the phone is not connected to it), regardless of whether it is an AC "wall wart" charger or a cigarette lighter charger (although normally turning the car ignition off turns the cigarette lighter outlet off, so if it drains the car battery the car ignition switch may have a problem). If the phone is connected to the charger it may continue to take extra power even with the phone fully charged (I have a Tracfone that will drain my battery powerpack completely (if not connected to a charger its internal battery drains completely in less than 2 days even if I'm not using it at all -- this phone has something wrong in it). The real issue is now fast the charger is draining the battery. BTW, I am assuming above that you mean an external battery that the charger is connected to, not the internal battery of the cell phone itself (if this is the case I would say the phone is seriously defective as this would normally not be possible).
The milli-amp-hours rating has nothing to do with the voltage. The rating should be something like 3000 mah at 12V or 3000 mah at 1.5V. One common 3000 mAh battery is 3.0 volts; another is 3.7 volts. A common camcorder battery is 7.4 volts. Some DeWalt tools use 12 V 3000 mAh batteries.
This depends on the type of battery. Car batteries are always charged while in use. With other types of batteries, this is not recommended and may result in a battery explosion or damage to the device the battery is powering.
Depends on the amperage of the charger. A 10 amp charger will charge it in about 1 hour.
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.
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.
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.
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.
wth a charger
sure, you can buy a battery charger that will charge any car battery.
If it is an automatic charger let it charge until the charger shuts off.
As long as both batteries are the same voltage, you can jump start with the battery. If you want to charge the battery then use a battery charger.
No, you can charge the battery while it's in the car.
It is perfectly fine to charge a power wheel battery with a car charger. It is imperative that you make sure the charger is set to the same voltage as the power wheels battery though.
